Hi Anam, You can get DEM data from the USGS National Map viewer. http://nationalmap.gov/viewer.html Sincerely, Brian Stice GISP Senior GIS Analyst [cid:[log in to unmask]] 650 Suffolk Street, Wannalancit Mills, Lowell, MA 01854 T: 978.656.3635 | LinkedIn<http://www.linkedin.com/company/trc-companies-inc> | Twitter<http://twitter.com/TRC_Companies> | Blog<http://blog.trcsolutions.com/> | Flickr<http://www.flickr.com/photos/trcsolutions/> | www.trcsolutions.com<http://www.trcsolutions.com/> From: Northeast Arc Users Group [mailto:[log in to unmask]] On Behalf Of Anam Khan Sent: Wednesday, April 15, 2015 10:40 AM To: [log in to unmask] Subject: question about GIS Project 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?
