Geospatial data for the Vegetation Mapping Inventory Project of Fort Vancouver National Historic Reserve

Published by National Park Service | Department of the Interior | Metadata Last Checked: January 25, 2026 | Last Modified: 2015-01-01T00:00:00Z
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. Data collected in the classification plots consisted of a GPS point, notes on the appearance of the site on the aerial imagery, site description, photo in each cardinal direction, plant association, confidence level of the association selection (weak, moderate, strong), and alternate association. Once the classification was finalized, all of the annotated polygons from the field maps were digitized using ArcMap 10.2 and attributed with a final association, alliance or map class. Because this was a true census (i.e. every portion of the Reserve was visited and there was no interpolation or modeling done) an accuracy assessment was not performed.
