The Earth Resources Observation Systems (EROS) Data Center, located in Sioux
Falls, SD is a data management, systems development, and research field center
of the U.S. Geological Survey's National Mapping Division.  The Center was
established in the early 1970's to receive, process, and distribute data from
National Aeronautics and Space Administration (NASA) Landsat satellites.  The
Center holds the world's largest collection of space and aircraft acquired
imagery of the Earth.  These holdings include over 2 million images acquired 
from satellites and over 8 million aerial photographs.  The Center is also a
major focal point for information concerning the holdings of foreign Landsat
ground reception stations and data acquired by other countries' Earth observing
satellites.
 
The EROS Data Center carries out a broad range of activities in the management
of global observations data, including the development and operation of advanced
systems for receiving, processing, distributing, and applying land related Earth
science, mapping, and other geographic data and information.  These data support
scientific studies, resource management and environmental monitoring activities
world-wide.  The Center is a major supplier of analytical and other support
services to Federal agencies involved in the application of these data to
research programs.
 
To support the Data Center's mission, the facility houses one of the largest
computer complexes in the Department of the Interior.  In addition to computers
to support scientific processing and analysis of data, over 100 locations in
Federal, State, and commercial offices are linked to the Center for data
inquiries.  More than 60,000 inquires and orders are received annually,
resulting in the distribution of over 250,000 products to scientists and 
resource managers around the world.
 
The Global Land Information System (GLIS) is an interactive computer system
developed by the U.S. Geological Survey (USGS) for scientists seeking sources of
information about the Earth's land surfaces.  GLIS contains metadata that is,
descriptive information about data sets.  Through GLIS, scientists can evaluate
data sets, determine their availability, and place online requests for products.
GLIS is more than a mere list of products.  It offers online samples of earth
science data that may be ordered through the system.
 
Scientists can use GLIS to bring up outlines of the geographic areas covered by
the data sets.  Using digital browse functions to manipulate the data, they can
determine such information as the amount of cloud coverage or the quality of an
image.
 
Online requests can be placed via GLIS for earth science data.  The producing
organization will receive the request and provide the user with price and
ordering information.
 
GLIS contains references to regional, continental, and global land information
including land use, land cover, and soils data; cultural and topographic data;
and remotely sensed satellite and aircraft data.  GLIS is routinely updated with
new data set descriptions, as they are contributed by the global change
scientific community.  GLIS inventories are reviewed daily to assure access to
the most current information.  The system operates 24 hours a day, 7 days a week
for world-wide connectivity and availability.
