Users are able to access socioeconomic, census, and GIS information for the state of New Mexico. Earth Data Analysis Center (EDAC) was established at the University of New Mexico (UNM) in 1964 to transfer NASA space-based technology to the private and public sectors. Their mission is to serve the needs of these communities by employing GI-science and technologies. They strive to bridge UNM’s academic units and the external communities they serve; to facilitate and stimulate collaborations between government agencies, between government and private organizations, and between universities in the region; and to strengthen graduate education to meet the increasingly complex resource management and decision needs. Since 1964, EDAC has expanded its services from a library clearinghouse (1968-present) to include remote sensing (1973), image processing (1979), GIS (1983), GPS (1990), and information technologies (1999). They provide a complete suite of Geospatial Information Science (GI-science) and technology services to all users. The New Mexico Resource Geographic Information System (RGIS) is the statewide clearinghouse for geospatial data for New Mexico that can be accessed through Earth Data Analysis Center or by going to

Data Notes

Using the New Mexico Resource Geographic Information System (RGIS) Data Clearinghouse, users can search for a variety of GIS data. Users are able to use the “Quick Search Bar” by searching by data title or place. Users can also browse by date last updated and defined folder categories. Users can use the “Advanced Search Feature” to perform a more complicated search of the data. Specifically, users can search by Place Name or Quad Name. Users can filter data by title key words, or folder categories for users to refine their search options. Users are able to download data in various formats which are displayed below each data set. Users can also view data using Metadata, Web Services, and the Map preview. Vector data use ESRI formats of ARC Export files and shape files. Raster files, such as images and DEMs, are GeoTiffs, .bils, or ARC/INFO Grids. Many of the .tif files have been compressed using MrSid, making their file extensions .sid. Non-spatial socioeconomic data is provided in the form of ASCII text files and Excel files. All the files have been zipped with WinZip for downloading. There is no indication of when the database will be updated next.
