The files linked to this reference are the geospatial data created as part of the completion of the baseline vegetation inventory project for the NPS park unit. Current format is ArcGIS file geodatabase but older formats may exist as shapefiles.

To produce the digital map, a combination of 1:12,000-scale true color aerial photography, 1:12,000-scale true color ortho-rectified imagery, and 3 years of ground-truthing were used to interpret the complex patterns of vegetation and land-use. In the end, 52 map units were developed and directly cross-walked or matched to corresponding plant associations and land-use classes. All of the interpreted and remotely sensed data were converted to Geographic Information System (GIS) databases using ArcGIS© software. Draft maps were printed, field tested, reviewed and revised. 1,122 accuracy assessment data points were collected and used to determine the map’s accuracy. After final revisions, the accuracy assessment revealed an overall thematic accuracy of 82%.
