Areas of Uncertainty Example

The following series of slides illustrate how error can be propagated when spatial data layers are combined by presenting the zone of uncertainty that actually surround data of a specific map scale. The example illustrates how, using raster modeling techniques, maps of uncertainty can be generated that reflect a level of confidence in data combined using GIS (from Dr. J.K. Berry).
