| What VISIT
Teacher Investigators are
learning about sources of geo-referenced data to use in their
Investigations. VISIT teachers look for data that will help
their students to understand and apply key concepts to their
own experience and their own local community's interests. Field
data collected by their own students often motivates and provides
a starting point for the inquiry. Teachers work with geo-referenced
digital data sets available from national, regional, state,
and local sources. VISIT staff and collaborating scientists
work with individual teachers to assist them in learning how
to identify, access, evaluate, and apply existing data bases
and student-collected data to their own projects. In the VISIT
Collaboratory, teachers learn these skills and concepts by working
with data sets that other VISIT teachers have already found
to be useful for a particular type and topic of investigation.
VISIT teachers, teacher leaders, and staff also work together
to perform these data mining steps with data sets that have
not yet been evaluated or processed. Teachers sometimes combine
data sets from their students' field data collection with other
data sources.
Steps in locating, accessing, evaluating and applying
data sets in VISIT:
- Becoming aware of national, regional, state,
and local sources of data relevant to air and water quality
and environmental hazards. The VISIT courses provide overviews
and online references to about 20 such sources, with practice
exercises in how to locate and access these. Teachers learn
to find and acquire geographic data via the Internet from
institutions like the U.S. Geological Survey, the U.S. Census
Bureau, the National Spatial Data Infrastructure, ESRI's ArcData
Online, state and county governments, as well as the VISIT
online data sets.
- Identifying types and properties of geographic
data and metadata, including entities and attributes, spatial
data organization, spatial reference systems, data quality,
map scale and map projections and georegistration.
- Evaluating candidate data sets for their relevance
and adequacy for addressing a particular investigation topic,locality,
and available tools. Criteria include, for example, parameters,
time frame, scale, geographic coverage, file formats, compatibility
with other data sets being used in the investigation and compatibility
with the software tools the teacher is using for analysis.
- Selecting and acquiring appropriate subsets
of available data for use in a particular investigation, and
performing any needed file format conversions and other preprocessing
steps.
- Mapping, graphing, and performing other visualization
and analysis steps to find patterns, formulate and test hypotheses,
interpret relationships in the data, in relation to other
sources of knowledge about the phenomena under study.
- Preparing presentations of the investigation,
such as thematic maps, charts, and written reports that incorporate
the data.

Climate Monitoring and Diagnostics Laboratory
http://www.cmdl.noaa.gov/
The Climate Monitoring
and Diagnostics Laboratory (CMDL) of the National Oceanic
and Atmospheric Administration, conducts sustained observations
and research related to source and sink strengths, trends
and global distributions of atmospheric constituents that
are capable of forcing change in the climate of Earth through
modification of the atmospheric radiative environment, those
that may cause depletion of the global ozone layer, and
those that affect baseline air quality. CMDL accomplishes
this mission primarily through long-term measurements of
key atmospheric species at sites spanning the globe, including
four fully-equipped Baseline Observatories. These key species
include carbon dioxide, carbon monoxide, methane, nitrous
oxide, surface and stratospheric ozone, halogenated compounds
including CFC replacements, hydrocarbons, sulfur gases,
aerosols, and solar and infrared radiation. The measurements
are of the highest quality and accuracy possible, and document
global changes in key atmospheric species, which are all
affected by mankind, identifying sources of interannual
variability. In addition, research programs in key regions,
utilizing an array of platforms including aircraft, balloons,
ocean vessels and towers, complement the land-based information.
CMDL's data are used to assess climate forcing, ozone depletion
and baseline air quality, to develop and test diagnostic
and predictive models, and to keep the public, policy makers,
and scientists abreast of the current state of our chemical
and radiative atmosphere. For more information, visit our
online
overview or find out more about our five research
groups.

Federal Geographic Information Clearinghouse
http://www.fgdc.gov/
The Geospatial Data Clearinghouse (FGDC)
is a collection of over 250 spatial data servers, that have
digital geographic data primarily for use in Geographic Information
Systems (GIS), image processing systems, and other modelling
software. These data collections can be searched through a single
interface based on their descriptions, or metadata.
The Federal Geographic Data Committee
coordinates the development of the National Spatial Data Infrastructure
(NSDI). The NSDI encompasses policies, standards, and procedures
for organizations to cooperatively produce and share geographic
data. The 17 federal agencies that make up the FGDC are developing
the NSDI in cooperation with organizations from state, local
and tribal governments, the academic community, and the private
sector.
The Clearinghouse Activity, sponsored
by the FGDC, is a decentralized system of servers located on the
Internet which contain field-level descriptions of available digital
spatial data. This descriptive information, known as metadata,
are collected in a standard format to facilitate query and consistent
presentation across multiple participating sites. Clearinghouse
uses readily available Web technology for the client side and
uses the ANSI standard Z39.50 for the query, search, and presentation
of search results to the Web client. A
fundamental goal of Clearinghouse is to provide access to digital
spatial data through metadata. The Clearinghouse functions as
a detailed catalog service with support for links to spatial
data and browse graphics. Clearinghouse sites are encouraged
to provide hypertext linkages within their metadata entries
that enable users to directly download the digital data set
in one or more formats. Where digital data are too large to
be made available through the Internet or the data products
are made available for sale, linkage to an order form can be
provided in lieu of a data set. Through this model, Clearinghouse
metadata provides low-cost advertising for providers of spatial
data, both non-commerical and commercial, to potential customers
via the Internet.
VISIT
participants have access to lessons called "Using Metadata and
Data Clearinghouses" that assist in using the FGDC. Contact

This site contains data sets from the USGS Global Change research
program.
Global GIS
http://webgis.wr.usgs.gov/globalgis/
The Global
GIS is built from relatively small scale data (1:1 million scale
or 1 Km resolution) and put on seven CD-ROM's organized by regions
of the world. Each CD-ROM integrates data for a given region
and includes a user-friendly GIS viewer. Also a single DVD-ROM
will be created that includes all the data with a refined interface.
The atlases contain the following datasets:
Country political boundaries, digital shaded relief map, elevation,
slope, hydrology, locations of cities and towns, airfields,
roads, railroads, utility lines, population density, geology,
ecological regions, historical seismicity, volcanoes, ore deposits,
oil and gas fields, climate data, landcover, vegetation index,
and lights at night.
Combining
existing global datasets in this manner enhances the impact
of individual data products and make the aggregate product attractive
to a larger and more diverse customer base. The Global GIS database
is designed to be used with the full version of ArcView 3.0 or higher, or
the included free software, ArcView Data
Publisher. Each CD will contain a suite of customized ArcView
tools specifically designed for the datasets, making it useful
for beginners or advanced GIS users. Interface
Snapshot
Application of GIS in the geosciences has grown explosively
over the past few years as scientists and land-use specialists
have been able to prepare thematic maps and determine spatial
relations among multiple datasets. Although GIS applications
hold great potential for most organizations, their availability
and application largely have been limited to institutions that
can afford and assemble the necessary hardware, software, datasets,
and hard-to-find technical expertise. Our approach can provide
a good source of data and GIS tools to the community at large.
The USGS
has a well-deserved reputation for the collection, interpretation,
and distribution of geologic, hydrologic, cartographic, and
biologic data. Although the Bureau's mission is primarily domestic
in focus, many of the datasets we develop are global. These
include the recently released Global Digital Elevation Model
(DEM), a wide variety of remotely sensed products, data on world
oil, gas, coal, and mineral deposits, biodiversity, and geologic
hazards (earthquakes, volcanoes, and landslides).
Virtually
all of these datasets are readily available in digital form,
either on the Internet or on CD-ROM. However, most of them are
stand-alone products, and, even though they are readily available,
they often require specialized software access. Very few have
been combined into integrated products.

National Hydrography Dataset
http://nhd.usgs.gov/
The National Hydrography Dataset (NHD) is a comprehensive
set of digital spatial data that contains information about
surface water features such as lakes, ponds, streams, rivers,
springs and wells. Within the NHD, surface water features are
combined to form "reaches," which provide the framework for
linking water-related data to the NHD surface water drainage
network. These linkages enable the analysis and display of these
water-related data in upstream and downstream order.
The NHD is based
upon the content of USGS Digital Line Graph (DLG) hydrography
data integrated with reach-related information from the EPA
Reach File Version 3 (RF3). The NHD supersedes DLG and RF3 by
incorporating them, not by replacing them. Users of DLG or RF3
will find the National Hydrography Dataset both familiar and
greatly expanded and refined.
While initially based on 1:100,000-scale data, the
NHD is designed to incorporate and encourage the development
of higher resolution data required by many users.
National Hydrography Dataset Tutorial Series. http://nhd.usgs.gov/tutorials.html
Each tutorial provides students with the opportunity to actively
learn about and use NHD data. The tutorials come with sample
NHD datasets and ArcView project files.
The
purpose of the NHD Tutorials is to acquaint users with the NHD
data model, learn how to use NHD data in simple query-and-display
applications, and to access and query NHD metadata.
The
NHD Tutorials are meant to be a companion to the NHD Technical
References documentation. There is a great deal of conceptual
information, background information, and detailed data-specific
information on the NHD
Technical References web site. Students are encouraged
to consult digital or hard copies of the documents posted on

federal agencies must seek to avoid or mitigate actions that
would adversely affect one or more NRI segments. The NRI is
a source of information for statewide river assessments and
federal agencies involved with stream-related projects. For
any group concerned with ecosystem management, the inventory
can provide the location of the nearest naturally- functioning

After reading this thread on
importing data into arcview,
I'd like to share 2 resources
I've used in the past:
First, for accessing data:
http://njgeodata.state.nj.us/
This
is the NJ geospatial
data clearing house.
Much of the data is in
".shp" or "shape file" format -
this is the most user
friendly for ArcView 3.x.
In
my searches, much of the data is available in an "E00"
format - here is a link that explains what to do with
it when you download this data to your computer:

New National Land Cover Dataset
http://edcwww.cr.usgs.gov/programs/lccp
The U.S. Geological Survey (USGS) and
the U.S. Environmental Protection Agency (EPA) have teamed up
to compile the first seamless National Land Cover Dataset (NLCD)
using satellite imagery for the conterminous United States.
At 30-meter resolution, the NLCD is the most detailed land cover
information ever compiled at a national level. The new CD-ROMs
include data for the states east of the Mississippi and Ohio
Rivers. Data for the remaining states will be available within
the next six months. The first eight CD's of a planned 31-volume
disc set contains 21 categories of land cover information across
the lower 48 states. These data are used in a variety of national
and regional applications, including watershed management, environmental
inventories, transportation modeling and land management."Many
federal, state, and local agencies rely on land cover data in
making critical decisions related to managing natural resources,"
said USGS associate director for geography Barbara Ryan. "Land
cover has changed considerably since the last data set was developed
in the 1970's, and it's important to provide resource managers
with the most up-to-date information available."The release of the CD's is the culmination
of a five-year effort by the USGS, EPA, the National Oceanic
and Atmospheric Administration and the U.S. Forest Service to
purchase and analyze the necessary Landsat satellite Thematic
Mapper imagery used in the NLCD. Scientists at the USGS used
a variety of supporting information in addition to the satellite
data, including topography, census, agricultural statistics,
soil characteristics, other land cover maps, and wetlands data
to determine and label the land cover type for each 30-meter
pixel. This imagery database is also being used by the partner
organizations for their own programs.The
NLCD was designed to be compatible with the earlier Land Use/Land
Cover data set compiled from 1970's and 1980's aerial photography.
The data from these two time periods provide an opportunity
to investigate the land cover change in the United States over
the last 30 years. The experience gained from this mapping effort
will be used to improve the next-generation national land cover
data set, which will use Landsat-7 data collected over the next
three years.
The CD-ROMs can be ordered from Customer
Services at the USGS EROS Data Center (605-594-6151; email custserv@edcmail.cr.usgs.gov;
FAX 605-594-6589), contact any other USGS Earth Science Information
Center or order online from this address: http://edcwww.cr.usgs.gov/programs/lccp/mrlcreg.html.

Characterization Program, please visit: http://edcwww.cr.usgs.gov/programs/lccp
As the Nation's largest water,
earth and biological science and civilian mapping agency, the
USGS works in cooperation with more than 2,000 organizations
across the country to provide reliable, impartial scientific
information to resource managers, planners and other customers.
This information is gathered in every state by USGS scientists
to minimize the loss of life and property from natural disasters,
to contribute to the sound conservation and economic and physical
development of the Nation's natural resources, and to enhance
the quality of life by monitoring water, biological, energy,
and mineral resources. For details - http://www.usgs.gov/public/press/public_affairs/press_releases/pr1299m.html
Joseph
Kerski, geographer at the USGS, provided the following additional
information in the VISIT Collaboratory:
I have briefly examined
the new USGS CDs of the National Land Cover Dataset.
These are geoTIFF files of 21 categories of land cover
info derived from Landsat TM imagery. Only the E 1/3 of the USA
is completed so far. The data is distributed by
state with several states on each CD. The initial
Landsat TM mosaics, all ancillary data sets, and the land
cover product are registered to an Albers Conical Equal Area
map projection.
Projection: Albers Conical Equal Area Datum: NAD 83
Spheroid: GRS 80 Standard Parallels:
29.5
degrees north latitude
45.5 degrees north
latitude Central Meridian:
96 degrees west
longitude Origin of the Projection:
23 degrees north
latitude False Easting:
0 meters False Northing:
0 meters
You can't do much analysis
with these raw geoTIFFs unless you're working
in a remote sensing environment with Image Analysis or
Imagine. However,
most people will probably want to
convert the image to a GRID, with either ArcInfo or ArcView
Spatial Analyst, which provides a grid of the
21 categories. Then,
optionally, depending on whether
the user wants to examine the data in a vector or raster
mode, one can convert it to a shape file.

U.S. Census Bureau TIGER files
http://www.census.gov/geo/www/tiger/index.html
The term TIGER® is the acronym
for Topologically Integrated Geographic Encoding and Referencing
which is the name for the system and digital database developed
at the Census Bureau to support its mapping needs for the Decennial
Census and other Bureau programs. The TIGER/Line files are a
digital database of geographic features, such as roads, railroads,
rivers, lakes, political boundaries, census statistical boundaries,
etc. covering the entire United States. The database contains
information about these features such as their location in latitude
and longitude, the name, the type of feature, address ranges
for most streets, the geographic relationship to other features,
and other related information. They are the public product created
from the Census Bureau's TIGER data base of geographic information.
TIGER was developed at the Census Bureau to support the mapping
and related geographic activities required by the decennial
census and sample survey programs.These
files are not graphic images of maps, but rather digital data
describing geographic features. To make use of these data, a
user must have mapping or Geographic Information System (GIS)
software that can import TIGER/Line data. The Census Bureau
does NOT provide these data in any vendor-specific format. With
the appropriate software a user can produce maps ranging in
detail from a neighborhood street map to a map of the United
States. To date, many local governments have used the TIGER
data in applications requiring digital street maps. Software
companies have created products for the personal computer that
allow consumers to produce their own detailed maps. There are
many other possibilities.
To
learn how to use TIGER files, you can download a series of ESRI
lessons "Don't be afraid of the TIGER" from http://www.emich.edu/visit/modules/ACF90C4.zip
THE TIGER/LINE PRODUCT DOES NOT
INCLUDE DEMOGRAPHIC STATISTICS. The Census Bureau's TIGER® System
automates the mapping and related geographic activities required
to support the decennial census and sample survey programs of
the Census Bureau starting with the 1990 decennial census. The
TIGER® System provides support for the following: - Creation
and maintenance of the digital geographic data base that includes
complete coverage of the United States, Puerto Rico, the Virgin
Islands of the United States, American Samoa, Guam, the Commonwealth
of the Northern Mariana Islands, the Republic of Palau, the
other Pacific entities that were part of the Trust Territory
of the Pacific Islands (the Republic of the Marshall Islands
and the Federated States of Micronesia), and the Midway Islands.
- Production of maps from the TIGER® database for all Census
Bureau enumeration and publication programs. - Ability to assign
individual addresses to geographic entities and census blocks
based on polygons formed by features such as roads and streams.
The design of the TIGER® data base adapts the theories of topology,
graph theory, and associated fields of mathematics to provide
a disciplined, mathematical description for the geographic structure
of the United States and its territories. The topological structure
of the TIGER® data base defines the location and relationship
of streets, rivers, railroads, and other features to each other
and to the numerous geographic entities for which the Census
Bureau tabulates data from its censuses and sample surveys.
It is designed to assure no duplication of these features or
areas. For details - http://www.census.gov/geo/www/tiger/index.html
U.S. EPA BASINS
http://www.epa.gov/OST/BASINS/
The U.S. Environmental Protection
Agency’s water programs and their counterparts in states and
pollution control agencies are increasingly emphasizing watershed
and water quality-based assessment and integrated analysis of
point and nonpoint sources. Better Assessment Science Integrating
Point and Nonpoint Sources (BASINS) is a system developed to
meet the needs of such agencies. It integrates a geographic
information system (GIS), national watershed data, and state-of-the-art
environmental assessment and modeling tools into one convenient
package. BASINS provides a useful source of information for
creating a GIS base map of your locality.Originally released in September 1996, BASINS addresses three
objectives: (1) to facilitate examination of environmental information,
(2) to provide an integrated watershed and modeling framework,
and (3) to support analysis of point and nonpoint source management
alternatives. It supports the development of total maximum daily
loads (TMDLs), which require a watershed-based approach that
integrates both point and nonpoint sources. BASINS can support
the analysis of a variety of pollutants at multiple scales,
using tools that range from simple to sophisticated.The
heart of BASINS is its suite of interrelated components essential
for performing watershed and water quality analysis. These components
are grouped into five categories:
- national databases;
- assessment tools (TARGET, ASSESS, and Data
Mining) for evaluating water quality and point source loadings
at a variety of scales;
- utilities including local data import, land-use
and DEM reclassification, watershed delineation, and management
of water quality observation data;
- watershed and water quality models including
NPSM (HSPF), TOXIROUTE, and QUAL2E; and
- post processing output tools for interpreting
model results. BASINS’ databases and assessment tools are
directly integrated within an ArcView GIS environment. By
using GIS, a user can fully visualize, explore, and query
to bring a watershed to life. The simulation models run in
a Windows environment, using data input files generated in
ArcView.
The following
is a quote from Charlie Fitzpatrick, education specialist at
ESRI:
(BASINS = Better
Assessment Science Integrating Point and Nonpoint Sources) It's
a rich website with data about watersheds in the 48 conterminous
states that can be used for detailed GIS projects. It's even
a bit intimidating. BASINS was designed for people doing hardcore
watershed analysis, and they have created sophisticated applications
using ArcView which can be downloaded or ordered for free. This
can all be a bit much for school use, but they also have elevation
files plus streams and other data sets, all neatly carved out
by 8-digit watershed. All the data are in decimal degree shapefiles,
so they work perfectly with ArcView or ArcVoyager. They're great
for doing a Community Atlas project, in combination with downloadable
TIGER data from the Census. It's a little tricky working with
the BASINS site because there is so much there, and EPA just
released the BASINS 3 update.
For a page of
instructions for accessing, downloading, and using the BASINS
data, which covers the version 3 update, see: http://www.esri.com/industries/k-12/basins.html If
you don't know your 8-digit watershed, the directions link you
to the EPA's "Surf Your Watershed" site, where you can find
it. Or, if you have ESRI's "GIS for Schools & Libraries"
CD, you'll find the 2-, 4-, 6-, and 8-digit watersheds on that
CD. This year, go beyond just awareness of rivers. Look at what
students can do to ensure the long-term health of our rivers.

ALOHA
http://www.epa.gov/swercepp/cameo/what.htm
CAMEO ® Computer Aided Management of
Emergency Operations is a system of software applications used
widely to plan for and respond to chemical emergencies. It is
one of the tools developed by EPA’s Chemical Emergency Preparedness
and Prevention Office (CEPPO) and the National Oceanic and Atmospheric
Administration Office of Response and Restoration (NOAA), to
assist front-line chemical emergency planners and responders.
They can use CAMEO to access, store, and evaluate information
critical for developing emergency plans. In addition, CAMEO
supports regulatory compliance by helping users meet the chemical
inventory reporting requirements of the Emergency Planning and
Community Right-to-Know Act (EPCRA, also known as SARA Title
III). CAMEO also can be used with a separate software application
called LandView ® to display EPA environmental databases and
demographic/economic information to support analysis of environmental
justice issues.
The CAMEO system integrates a
chemical database and a method to manage the data, an air dispersion
model, and a mapping capability. All modules work interactively
to share and display critical information in a timely fashion.
The CAMEO system is available in Macintosh and Windows formats.MARPLOT
® - Mapping Applications for Response, Planning, and Local Operational
TasksMARPLOT is the mapping application for CAMEO. It allows
users to "see" their data (e.g., roads, facilities, schools,
response assets), display this information on computer maps,
and print the information on area maps. The areas contaminated
by potential or actual chemical release scenarios also can be
overlaid on the maps to determine potential impacts. The maps
are created from the U.S. Bureau of Census TIGER/Line files
and can be manipulated quickly to show possible hazard areas.
ALOHA ® - Areal Locations of Hazardous Atmospheres
-- ALOHA-- is an atmospheric dispersion model
used for evaluating releases of hazardous chemical vapors. ALOHA
allows the user to estimate the downwind dispersion of a chemical
cloud based on the toxicological/physical characteristics of
the released chemical, atmospheric conditions, and specific
circumstances of the release. Graphical outputs include a "cloud
footprint" that can be plotted on maps with MARPLOT to display
the location of other facilities storing hazardous materials
and vulnerable locations, such as hospitals and schools. Specific
information about these locations can be extracted from CAMEO
information modules to help make decisions about the degree
of hazard posed.

Watershed Data/Toxic Overloads Data for Lesson 2
Hi all!
We would begin with the discussion of water quality generally
for our lesson plans.
This would inevitably contain a strong math/science application,
as well as the interdisciplinary one.
So ... I linked to “Watershed Information Network”

was a great map of the September 1999 IWI Release rating
various watershed vulnerability.
Not only was data given, but there was a section titled: “importance of the national
watershed characterization.”
Another data set that I found quite interesting, perhaps
even more usable to the unit might be:

Date of Collection: From 1780s to present 1990s
(Wetlands), from 1970 to 1995 (Risk of Groundwater
Nitrate Contamination); various, based on data set.
Data Collection Methods: The data was originally
collected depending on type of water quality measured.
For instance, three data sets are combined to produce a
partial picture of the condition of rivers,
lakes/reservoirs, and ground waters used by public
drinking water systems. While the contaminated sediments
data includes data from sediment chemical analysis,
sediment toxicity data, and fish tissue residue data.
The ambient water quality data shows “percent
exceedences of national criteria levels, over a six year
period (1990-1996), of copper, chromium (hexavalent),
nickel, and zinc.” from, Index of Watershed Indicators:
An Overview, http://www.epa.gov/iwi/iwi-overview.pdf
Spatial Reference: “A watershed is the land area that drains
to a waterbody and affects its flow, water level, loadings of
pollutants, etc….Watersheds are defined in nature by topography. The US Geological Survey has
developed a Hydrologic Unit Classsification (HUC) System of
watersheds at various scales and mapped these watershed. The IWI is depicted at the
‘eight digit scale—the smallest nationally consistent set of
watersheds in the HUC system.’
Projection or Coordinate System: Varies based on sample
type, similar in format: “This map is a representation
of threatened and impaired streams, rivers, coastlines, estuaries,
lakes and wetlands within an 8-digit Hydrologic Unit Code (HUC),
divided by the total number of water miles within the HUC.”
File Type: This data has been found in these types of
files: CSV, GIF, MDB, TXT, HTTP, WPD (again depending on data)
Size of Data Set: Various file sizes, when listed: 8 to 50 KB

U.S. Geological Survey Hawaiian Volcano
Observatory
http://wwwhvo.wr.usgs.gov/
This site provides all imaginable information
about the Hawaiian volcanoes. The Hawaiian Islands are at the
southeastern end of a chain of volcanoes that began to form
more than 70 million years ago. Many of these volcanoes formed
islands that have subsided and eroded beneath sea level, and
some of the old volcanoes probably never reached sea level.
Each Hawaiian island is made of one or more volcanoes, which
first erupted on the sea floor and only emerged above the ocean's
surface after countless eruptions.
The largest and most southeastern island
of the chain, Hawai`i, consists of five volcanoes. Kilauea,
Mauna Loa, and Hualalai have erupted in the past 200 years.
Lo`ihi, the youngest volcano of the Hawaiian Volcanic Chain,
is still about 1,000 meters beneath the ocean's surface. East
Maui Volcano, commonly known as Haleakala, on the island of
Maui, is the only other Hawaiian volcano to have erupted since
the late 1700's.
U.S. Geological Survey Real Time Water Data
http://water.usgs.gov/realtime.html
Using a map you can select the
10 nearest stations to the point you click, a list of all the
stations in a state, or an interactive map of a state. You also
may use a list to obtain data by state. The stream-gaging program
of the USGS does not represent a single "network" of stations,
but is an aggregation of networks and individual stream flow
stations that originally were established for various purposes.
Because the data from about 4,200 of the 7,292 stations are
telemetered by an earth-satellite-based communications system,
those data are available in realtime for many agencies to conduct
water-resources projects and for the National Weather Service
(NWS) to forecast floods. Data from the active stations, as
well as from discontinued stations, are stored in a computer
data base that currently holds mean daily-discharge data for
about 18,500 locations and more than 400,000 station-years of
record, or more than 146 million individual mean daily-discharge
values. Additional data are added to the database each year.
The stream-discharge data base is an ever-growing resource for
water-resources planning and design, hydrologic research, and
operation of water-resources projects. Increasing the length
of individual station records is valuable for at least two reasons.
Additional years of record provide ever-improving accuracy of
estimates of stream flow characteristics, such as the magnitude
of extreme infrequent floods or low flows, and an opportunity
to determine how stream flow characteristics are changing over
time due to such causes as agricultural practices, urbanization,
ground-water development, or climate change. Today, more than
one-half of the currently operating stations have equipment
that permits immediate transmission of data by means of satellite
from the data-collection site. By using the telemetry, data
are transmitted around the clock by means of two geo-stationary
operations environmental satellites (GOES) that are positioned
above the Earth at an altitude 22,300 miles above the Equator
over the eastern Pacific Ocean and Brazil. The satellites are
operated by the National Oceanic and Atmospheric Administration.
These data then are retransmitted by means of a domestic satellite,
and the resulting signal is received by the USGS and other users.
The transmission and receipt of the signals are automated, as
are the provisional discharge computations that are available
for meeting current data needs. For

The Virginia Spatial Metadata Clearinghouse
Search Tool lets you customize your search in four different
areas:
- Nodes: Simultaneously search one or
more data sources from around the state, region and country.
- Keywords: Enter up to four keywords
or phrases to specify the type of data desired.
- Location (optional): Identify the geographic
area you are interested in by selecting from the menus or
drawing on a map.
- Time Period (optional): Specify the
time period for the data you want.
A Virginia Spatial Metadata Clearinghouse search
returns titles of data sets that match your selection criteria.
Each title links you to a detailed description of the data,
called metadata, which includes the most important facts about
the data and information on how to obtain a copy. Data often
can be downloaded directly through the metadata.
Water on the Web
http://wow.nrri.umn.edu/wow/index.html
WOW's primary goal is to train students to understand
and solve real-world environmental problems. Water on the Web
(WOW) offers unique opportunities for high school and first
year college students to learn basic science through hands-on
science activities, in the lab and in the field, and by working
with state-of-the-art technologies accessible through a free
web site. Teacher and student lesson plans can be found on the
site under the headings "Teacher" and
"Student".
Real water quality data, provided
in real-time and archived formats, is obtained through the project's
Remote Underwater Sampling Stations (RUSS). Currently we are
providing data from five RUSS units that are located in four
Minnesota lakes.
Data visualization tools embedded in the web site allow students
to see and explore relationships that might be lost to them
when the data appears as just arrays of numbers. The data visualization
tools and data are both found under the "Data" portion of the
site.

Water on the Web.
This site allows students (and teachers) to work with
either real-time or archived data from 5 Minnesota
lakes. The impact of human development on lake ecology
and the overall water quality within the region is
studied. GIS (maps and an interactive section) is used
to help users understand the region being studies.
ArcIMS allows you to view maps and manipulate them
on-line, without having GIS software installed on your
computer.
The site is divided into two main sections; one for
teachers and one for students. The teacher area contains
many very well done lesson plans. The student area is
divided into two components: directed study and inquiry.
One lesson I examined more closely involved data
interpretation. The tool the site has the students use in this
lesson is Excellent.

I found the WOW material very useful
in applying to any topic. The material is well organized
and gives strong student instruction as well good
teacher support. It shows student application directly
so there is no real need for a busy teacher to reinvent
activites. It has very interesting initial research
questions that students could take to a variety of
levels and easily expand upon. The data is obtained from
a WOW site and analyzed using excel, a program most of
us have access to. They use poster presentation for
reporting out and give very good hints as to what makes
a good reseach poster. It is a good lead in for science
projects in science fairs as well in poster design,
scienctific method and data analysis. This activity
also gives strong support for student sto use graphs to
display data as an effective communication tool. I
think it could be a great early lesson for students,
especially young students. Jackie

The Weather Underground
http://www.wunderground.com/
This user-friendly and very
popular weather information site was originally designed by
a graduate student in meteorology at the University of Michigan
to provide real-time weather data to school children. The name
"The Weather Underground" is a tongue-in-cheek reference to
the 1960's radical group that also originated at the University
of Michigan in 1991. The web site matured in 1998 with the addition
of several foreign languages, leading the Weather Underground
toward its current state as the most widely translated weather
site in the world - over 35 languages. Media Metrix named the
wunderground.com site as the #5
most used sites by kids.
