“S-BAND”, a model to describe uncertainty of an objectin an integrated GIS/remote sensing environment

摘要

In a geographic information system (GIS) an object is generallydefined by two aspects, positional and thematic values. It is possibleto have error indicators to describe the positional accuracy and todescribe thematic accuracy. However, ther is not a well developed theoryto derive a combined uncertainty indicator for a GIS object. the authorspresent a strategy for such a combined error model, the“S-BAND” uncertainty model. This model is based on acombined uncertainty indicator with both positional and thematic aspects
