Hello all,
I am working on a GIS project to map campsites found in a wilderness area. I'm working with the Forest Service and their inventory data for campsites.
I have three feature classes:
campsites.shp: point data for campsites found in the wilderness
SystemTrails.shp: official Forest Service trails in the wilderness
hydro.shp: line data that shows all the streams in the wilderness
I have two questions:
1. Does anyone know how I can download free DEM data for a certain location from USGS?
2. If I have contour elevation data that I can get from the DEM, is there a way to extract the elevation that a certain campsite falls on and add that elevation to the attribute table of campsites.shp for that specific campsite?
Thanks,
Anam Khan
