Geospatial data for the Vegetation Mapping Inventory Project of Rocky Mountain National Park
2004. Geospatial data for the Vegetation Mapping Inventory Project of Rocky Mountain 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. To produce the digital map, we used a combination of 2001 1:12,000-scale true color aerial photography, 2001 1:40,000-scale true color ortho-rectified imagery reproduced at 1:12,000-scale, and 3 years of ground-truthing to interpret the complex patterns of vegetation and landuse at ROMO. In the end, 46 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 ArcInfo© software. Draft maps created from the vegetation classification were field-tested and revised before independent ecologists conducted an assessment of the map’s accuracy during 2004.
