Geospatial data for the Vegetation Mapping Inventory Project of Buck Island Reef National Monument
2010. Geospatial data for the Vegetation Mapping Inventory Project of Buck Island Reef National Monument
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. Polygons were digitized in ESRI ArcMap for the entirety of Buck Island based on an initial photo-interpretation of the digital orthoimage within a range of 1:200 through 1:7000 scales. The variation in scale proved helpful in defining larger polygons at larger scales and vice versa. Vegetation polygons in general were digitized with a minimum mapping unit of 400m2. However nine polygons were digitized smaller than the minimum mapping unit. All nine of these polygons had a high degree of certainty in their mapping class and location (e.g., buildings).
