I am trying to run an spatial analysis on a line using elevation data and a polyline running through mulitple counties. I'm using http://seamless.usgs.gov/ to get my elevation. But when I add it in my .mxd its boundries have shrunk greatly.
I orignally thought it may be a projection issue. But I made sure my data frame was in GCS_North_american_1983 to match the NED from usgs in GCS_North_american_1983 Any ideas?
Attached is a screen grab. The DEM shown in OK should actually take up most of OK.
