Abstract
Geostatistical Interpolation of Historical GLO Forest Data, Luce District, Michigan
Track: Forestry, Wildlife, and Fisheries Management
Author(s): Karen Owens, Ann Maclean
General Land Office (GLO) survey witness tree data for an area (583,000 ha) located in the central Upper Peninsula of Michigan as used to generate a pre-European settlement forest cover map. Two geostatistical techniques-indicator kriging (IK) and inverse distance weighting (IDW)-were used to interpolate the point tree data. Ancillary soils information was included in the analysis to aid in the interpolation process. The results of these analyses were compared to the Michigan Natural Features Inventory (MNFI) manually interpreted presettlement forest cover map to assess the consistency of the forest cover polygon labeling and forest cover type identification.
