Title	Michigan's Native Landscape - As Interpreted from the General Land Office Surveys 1816-1856
Abstract	Vegetative cover maps derived from General Land Office Survey notes (1816-1856), polygon interpretation included use of supplemental mapping sources such as 1:24k topographic quads, soil surveys, wetlands, etc. Boundary lines originally were drawn on 1:24k quad sheets, and digitized (by county) in Intergraph format. The Great Lakes Assessment converted the county coverages to Arc/Info format, edge-matched the county maps, converted the individual county coverages from three state plane coord. systems to a single Albers projection and combined them into one coverage. Data set is being distributed as two separate coverages, one for the Upper Peninsula and one for the Lower Peninsula. After this data was assembled, it was clipped with the 50 km buffered basin boundary, and then split into counties on the US side. On the Canada side, the data was left whole. This was done to provide easier access for downloading the data sets.

Attribute Accuracy	Final, combined coverages were check spot checked for errors due to appending the individual county coverages together. In places were two labels or no label occurred, the original Intergraph coverage was consulted, and the Arc/Info polygon attributes corrected. Where the Intergraph information was insufficient, a very few cases, MNFI staff members were consulted on the correct polygon value. MNFI staff are currently conducting a final review of the entire coverage.
Logical Consistency	Contact NRRI, Mark White
Completeness	Only the vegetative cover type polygon information was converted; the original Intergraph coverages contain additional information on cultural and natural features, section and township lines, and other geographic features.
Horizontal Positional Accuracy	Consult MNFI staff for information on original digitization accuracy (http://www.dnr.state.mi.us/wildlife/Heritage/Mnfi/main.htm). Some movement of County boundaries and polygon lines occurred during the edgematching process. This was un-avoidable, and care was taken to minimize the extent of change to any individual coverage. In general, the most interior counties were held constant and the adjoining counties were edgematched to those, and then the process was repeated radiating outward from the center to the lake shore(s) and state line(s). All coverages were edgematched in the original Michigan State Plane (MSP) Coordinate system, and then converted to an Alber's Equal Area Conic projection within Arc/Info. The only exception to this was the boundary along the MSP-Central and MSP-South boundary, which had to be converted to a common projection prior to edgematching. During the edgematching process, records were kept of places along the county boundaries were connecting arc segments were missing or significantly shifted away from the intended connection point. Some of the missing arc errors were corrected (only in very obvious cases), the rest were noted, and MNFI has been given a complete report. The APPEND and CLEAN commands in Arc/Info were used to join the county coverages, and some movement of arcs/nodes did occur as part of the CLEAN process. Select portions of the final conbined coverage were compared with the original Intergraph files (side-by-side on the same screen) to see if any major alterations had occurred. Specifically, rivers and very narrow polygons were analyzed to see if nodes had snapped together. This did occur to a very limited extent in the combined coverages, and usually where polygons narrowed to a narrow point or at bends along narrow streams.
