Recognition and assessment of error in geographic information systems

Abstract:

Depending upon the level of error inherent in the source data and the error operationally produced through data capture and manipulation, GIS products may possess significant amounts of error. Errors inherent in 1) land-cover maps derived through classification of Landsat digital data; 2) slope-angle and slope-aspect information derived from digital terrain tapes; and 3) soil-type data acquired from USDA Soil Conservation Service soil survey reports, were assessed. These data were compared to field information collected for 35 sample sites. -from Authors
