Title:Conterminous U.S. Prototype 1990 Land Cover Characteristics Data Base
Source:USGS EROS Data Center605-594-6151
Description:This CD-ROM contains a prototype land cover characteristics data base for the conterminous United States (lower 48 states) derived from the classification of 1990 AVHRR time-series satellite data, with post-classification refinement based on other digital earth science data sets, including topography, climate, soils, and ecoregions. The Center for Advanced Land Management Information Technologies of the University of Nebraska at Lincoln was a major collaborator in this effort.The data files include (1) the source data, (2) the initial and the final interpretation of land cover regions, (3) descriptive and quantitative attributes for each of the land cover regions, and (4) derived thematic data sets. It contains the complete land cover characteristics data base and is intended to provide users with the flexibility to tailor data the unique requirements of a variety of applications. The data base provides researchers with the capability to compute new parameters, derive new classifications and aggregations of the data to suit specific needs, and to develop custom products. The data on the CD-ROM also complements the 1989-1993 AVHRR CD-ROMs and the AVHRR Companion Disc produced by the USGS. |
