GAP Ecological Systems (Gap Analysis Program - Northwest) 30m for Wyoming

Summary

Multi-season satellite imagery (Landsat ETM+) from 1999-2001 were used in conjunction with digital elevation model (DEM) derived datasets (e.g. elevation, landform, aspect, etc.) to model natural and semi-natural vegetation. The minimum mapping unit for this dataset is approximately 1 hectare. Landcover classes are drawn from NatureServe's Ecological System concept. For the majority of classes, a decision tree classifier was used to discriminate landcover types, while a minority of classes (e.g. urban classes, burn scars, etc.) were mapped using other techniques..
