U.S. Potential Natural Vegetation, Original Kuchler Types, v2.0 (Spatially Adjusted to Correct Geometric Distortions)

Oct 30, 2012
Description:
This dataset was created by performing spatial adjustments on the original Kuchler dataset in order to correct for geometric distortions identified in the digital source data.  The adjustment was performed manually in ArcGIS 10.0 using the rubbersheeting adjustment method.

Note that alignment errors may still be present in this dataset, particularly towards the center of United States where displacement links were not used during the spatial adjustment process.

Source Data Description:

This coverage was digitized at the USA EPA from the 1979 Physiographic Regions Map produced by the Bureau of Land Management, which added 10 physiognomic types to Kuchler's 1966 USGS Potential Natural Vegetation map (and similarly differs from the 1985 US Geological Survey map revised by Kuchler and others) The dataset consists of two thematic layers a) Vegetation Form and b) Vegetation Type.  Dataset is a polygon coverage with 6700 meter mean consecutive point spacing.
