Section 1	Identification Information
Originator	Brian Hargrave-Minnesota DNR
Title	Minnesota Early Vegetation
Abstract	This data set contains early settlement vegetation for Minnesota that is within the boundary of the Great Lakes Assessment (GLA) study area. The coverage was digitized by Brian Hargrave of the Minnesota DNR from a 1:500,000 scale paper map originally created by F.J. Marscner. Marschner's methods are not fully documented, but it is known that he used General Land Office (GLO) notes and maps from the original land survey conducted during 1847-1907 in Minnesota. He is thought to have supplemented this information with descriptions of soils, landforms and vegetation. GLA personnel re-projected the coverage, clipped it to the GLA boundaries and reclassed Marschner's vegetation codes to match the 8 class GLO vegetation codes. After this data was assembled, it was clipped with the 50 km buffered basin boundary. This was done to provide easier access for downloading the data sets.

Lineage	Process Step Process Description: Projected from UTM 15 to Albers Equal Area (GLA). Boundaries were clipped to the Great Lakes Assessment (GLA) study area within the state. Process Date: 1997 Process Step Process Description: New GLA class = Marschner Veg Class 1 = 10 ,11,12 2 = 13, 14, 15 3 = 5, 6 4 = 7 5 = 9 6 = 4, 8 7 = 1, 2, 3, 16, 0 8 = 17 Process Date: 1997 Data was then clipped with the 50 km lake superior basin boundary, and split into county coverages for the US side. It was left whole for the canadian side.
