The project was funded in 1989 by the State Legislature per recommendation from the Legislative Commission on Minnesota Resources incooperation with the Red River Watershed Management Board. LMIC is the final repository for the resulting data. The Data is derived principally from 1990 vintage aerial photography. It has been subjected to variety of data processing processes in the interim period through which the information content of the data has been preserved. This data set was developed independently of other DNR GIS data resources.
All polygons are closed and lines intersect where intended.
Although the data have been processed to eliminate overlaps between individual tile coverages, some processing failures have occurred when joining tiles into spatially larger blocks. These occurrences have been rare, and the underlying data problems have been corrected as they have been identifed. Completeness Completeness of the data set is uncertain. Edgematching problems are common throughout the data set, although DNR has reconciled the neat line boundaries between processing modules. The data extent is essentially limited to the non-forested regions of the state, although good coverage is locally present in some areas of the state.
