ACCURACY AND CONSISTENCY COMPARISONS OF LAND USE AND LAND COVER MAPS MADE FROM HIGH-ALTITUDE PHOTOGRAPHS AND LANDSAT MULTISPECTRAL IMAGERY

The Central Atlantic Regional Ecological Test Site (CARETS) project (NASA-USGS) evaluated data from the title map-making techniques as inputs to a regional land resources information system. Accuracy analyses for land use and land cover maps of the 74.712 sq km were performed for a 1-percent sample of the area. Researchers compared Level II land use and land cover maps produced at three scales, 1:24,000, 1:100,000, and 1:250,000 from high-altitude photographs, with point data obtained in the field. The same procedures were employed to determine the accuracy of the Level I land use and land cover produced at 1:250,000 scale from high-altitude photographs and color composite Landsat imagery. Accuracy of the Level II maps was 85 percent at 1:24,000, 77 percent at 1:100,000, and 73 percent at 1:250,000. Accuracy of the Level I 1:250,000 maps produced from high-altitude photographs was 77 percent and for those produced from Landsat multispectral imagery was 70 percent. Accuracy of the Level I land use maps produced using Landsat imagery is approximately that of the Level I land use maps produced from high-altitude photography with the exception of urban and built-up land. No built-up land was identified from landsat imagery in the non-urban areas.
