National Land Cover Dataset
MRLC is a successful example of a bottom-up, E-Government initiative where several federal agencies have collaborated in a collegial environment to provide digital land-cover and ancillary data to the nation. A host of Federal Institutions participate in MRLC including U.S. Geological Survey (USGS), Environmental Protection Agency (EPA), National Oceanic and Atmospheric Administration (NOAA) and the U.S. Forest Service (USFS). Later joining the consortium were the National Atmospheric and Space Administration (NASA) and the Bureau of Land Management (BLM), National Park Service, U.S. Fish and Wildlife Service (USFWS), National Aeronautics and Space Administration (NASA), Office of Surface Mining (OSM), and the Natural Resource Conservation Service (NRCS).
The MRLC Consortium produces four different land-cover databases. The mapping efforts are not duplicative: all three use the same basic methods and data, and mapping done in one project supports the other two. The primary source of data for all three mapping efforts is Landsat (TM).

Census Tiger Data
# TIGER/Line®Shapefiles are spatial extracts from the Census Bureau's MAF/TIGER database, containing features such as roads, railroads, rivers, as well as legal and statistical geographic areas.
# TIGER/Line®Shapefiles are made available to the public for no charge and are typically used to provide the digital map base for a Geographic Information System or for mapping software.
# TIGER/Line®Shapefiles are designed for use with geographic information system (GIS) software. The TIGER/Line®Shapefiles do not include demographic data, but they contain geographic entity codes that can be linked to the Census Bureau’s demographic data, available on American FactFinder

USGS Topographic Change Site
The USGS has developed a national inventory of significant topographic changes based on seamless multitemporal elevation data and land cover data. The National Elevation Dataset (NED) and the Shuttle Radar Topography Mission (SRTM) data form a unique pair of seamless elevation datasets that can be used to detect and analyze 20th century topographic surface changes in the United States.

NRCS Soil Data Mart
Welcome to the Soil Data Mart! The Soil Data Mart allows you to:
* Determine where soil tabular and spatial data is available.
* Download data for one soil survey area at a time. (Download requests for more than one survey area at a time can be submitted through the Geospatial Data Gateway. Going through the Geospatial Data Gateway also provides the option to obtain data on CD or DVD.)
* Download a template Microsoft Access® database for working with downloaded data.
* Generate a variety of reports for one soil survey area at a time.
* Find out who to contact for information about soil data for a particular state.
* "Subscribe" or "unsubscribe" to a soil survey area. A person who is subscribed will automatically be notified whenever data for that soil survey area is updated. You must register and login before doing this.
