The GeoResources Data Library will provide a "front door" into GRI for data access and processing. This "front door" will provide a comprehensive query capability for data discovery, a mechanism for data ordering and delivering, and a number of data processing tools. However, we are in the process of preparing GRI's Data Library for public release.

This satellite image of Starkville, MS is an example of imagery data that will be available soon via the GRI Data Library. DigitalGlobe's QuickBird satellite, which was launched in 2001, took this image on March 17, 2004. Click the thumbnail to view a larger image.

In the meantime, please utilize the current online access or contact information for the different items that are available:

• Remote Sensing Technologies Center's Data Warehouse - The Remote Sensing Technologies Center's Data Warehouse houses several different types of imagery data, including Airborne Terrestrial Applications Sensor (ATLAS) data, and Geovantage Digital Camera System data. A catalog of the datasets available is provided. Questions about the Data Warehouse should be directed to rstcdata-support@erc.msstate.edu.


• Mississippi Digital Earth Model (MDEM) Aerial Orthoimagery - MDEM is an up-to-date, highly detailed, computerized map of the State of Mississippi similar to and coordinated with the National Map being compiled at the federal level by the United States Geological Survey (USGS).
  
  The original GeoTiff imagery and MrSid imagery are distributed directly to county governments. Anyone may download mosaics in MrSid Generation 3 imagery from the website of the Coordinating Council for Remote Sensing and Geographic Information Systems. MrSid Generation 2 mosaic imagery is also available from the Mississippi Automated Resource Information System (MARIS).
  
  A free MDEM Image Viewer is available from either website mentioned above. The MDEM Image Viewer is simple to install and use and is designed specifically for use with MDEM orthoimagery. The MDEM Image Viewer was developed by Dr. Scott A. Samson of Mississippi State University’s GeoResources Institute. For more information, a MDEM FAQ is available.


• Ground Truth Data - Ground Truth data of surface features is collected with an Analytical Spectral Device (ASD) spectroradiometer with a spectral range from 350 to 2500 nanometers. Each ground truth dataset comes with observations on meteorology during collection, latitude/longitude of each ground truthed point, digital photos and a description of the feature. Other observations are noted if required. Currently, the data is not available online. For more information, please contact Louis Wasson at lwasson@gri.msstate.edu.
