Abstract
Vegetation Mapping for San Juan Island National Historical Park, WashingtonTrack: Forestry, Wildlife, and Fisheries Management
Author(s): Robert A. Norheim, David L. Peterson
We have developed geodatabases of vegetation and fuels for San Juan Island Historical Park using field-based classification and data collection. This will provide park managers with a valuable database relevant to scientific and managerial applications. We outlined patches on color DOQs using color and texture clues in the imagery. We then conducted sampling in the field, touring all of each patch and revising boundaries as necessary. Because the park is only 715 hectares, we were able to achieve essentially 100 percent coverage. Allocation of heterogeneous patches to combinations of fuel models and community types led to some interesting cartographic results.
