Geographical information science: geostatistics and uncertainty

The assessment and modelling of uncertainty in GIS continues to be one of the most important areas of GIS research. The emphasis in this report was on the geostatistical assessment of uncertainty. In particular, the indicator formalism was described to encourage practitioners to move on from the Gaussian formalism to approaches which naturally allow for the assessment of uncertainty in spatial data (Isaaks and Srivastava, 1989; Journel, 1996). © Arnold 1999.
