An evaluation of SPOT capability for mapping the geology and soils of Central Java

Stereoscopic SPOT P and monoscopic SPOT XS data were tested for assessing the SPOT capability for geological and soil mapping in Indonesia, down to 1:50 000 and 1:100 000 scales. Methodological approaches for spatial and spectral analyses of SPOT images are briefly discussed and illustrated. The operational SPOT capability was tested with the geological and soil mapping of Wonosari (Central Java) from monoscopic SPOT XS data. Generally speaking, results compared well with mapping from 1:50 000 infrared aerial stereo-pairs. The paper concludes that SPOT has the potential of a major data source for operational small/medium scale geological and soil surveys in Indonesia.
