Geospatial data for the Vegetation Mapping Inventory Project of Zion National Park
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.
The map units delineated on the orthophotos were derived from the NVC classification as constrained by the limitations of the photography. We combined the preliminary NVC classification with the aerial photo signatures to determine how many plant associations could be recognized on the photos. In most instances, one NVC association corresponded to one map unit. However, sometimes a plant association could not be recognized consistently on the photos or we could see more detail than was recognized by the classification. These problems were overcome by using two separate but related classifications: 1) the NVC for the plot data and 2) map units for the GIS database. The two were related or “crosswalked” by noting when plant associations were lumped into a single map unit or where when associations were split into multiple map units.
