Cold Land Processes Field Experiment Plan - December 7, 2001

6. GIS DATA SETS


A large number of geo-spatial data sets exist for the experiment study area. These include a variety of geophysical variables such as elevation, soils, hydrography, land use, and vegetation data, as well as a variety of "logistical" data sets, such as transportation, hospitals, and station locations for various measurement networks. Many of these GIS data sets have been collected to assist with experiment planning. A CD-ROM containing a CLPX Digital Atlas in ArcView format was prepared and distributed to the CLPWG (and on the web) in June of 2000. The Digital Atlas will be updated with finalized study area boundaries and new data sets prior to the experiment.
 

6.1. CLPX DIGITAL ATLAS (ARCVIEW)

The CLPX Digital Atlas is a compilation of spatial data sets (currently) for the Small-Regional Study Area. The Digital Atlas is in ArcView GIS format. An ArcView project is the primary method for viewing the geographic data. The Spatial Analysts extension for ArcView is required to view the atlas. The Digital Atlas v1.0 is available on the Cold Land Processes web site at: http://www.nohrsc.nws.gov/~cline/clp.html.

All data sets in the atlas are geo-registered. Data sets in the atlas include:

  1. Landsat TM Composite
  2. Digital Elevation Data (USGS)
  3. Forest Cover Density (USDA)
  4. Forest Cover Type (USDA)
  5. Land Use/Land Cover (USGS, EPA)
  6. Soil Texture Classes (CONUS-SOILS, STATSGO)
  7. Soil Sand/Silt/Clay Fractions (CONUS-SOILS, STATSGO)
  8. Soil Bulk Density (CONUS-SOILS, STATSGO)
  9. Soil Porosity (CONUS-SOILS, STATSGO)
  10. Areal Extent of Snow Cover (NOHRSC)
  11. Monthly Precipitation (NRCS-PRISM)
  12. Roads - Primary, Secondary, Tertiary (Colorado DOT)
  13. Hospitals and Emergency Facilities ( Colorado Department of Public Health and the Environment)
  14. Airports
  15. Operational GAMMA Flight Line Network (NOHRSC)
  16. SNOTEL and Snow Course Network (NRCS)
  17. Cities
  18. Counties
  19. Operational Forecast Basin Boundaries (NWS)
  20. National RF-3 Hydrography Dataset (USGS)
  21. Hydrography (Rivers and Lakes) (USGS)
  22. Study Area Boundaries
