Geospatial data for the Vegetation Mapping Inventory Project of Padre Island National Seashore
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.
ECognition software was used to circumscribe visually homogeneous polygons. Multiresolution segmentation (Scale parameter: 25, Shape: 0.2, Compactness: 0.2) was applied to four bands of 1 meter (3.3 ft) National Agricultural Imagery Program (NAIP) imagery and normalized difference vegetation index (NDVI) derived from the imagery. We used eCongition to calculate eighty-one variables and attributed the variables to the polygons. These variables summarized attributes of the topographic relationships of the polygons, reflectance values derived from aerial photography, surficial geologic composition, and vegetation height.
