I have a route that crossed into a new Lat Lon and or a different DEM (hgt) file area, and the terrain stops dem-ing at the border from one longitude to the next. Hitting ‘T’ on one side of the route is fine but stops at the point where it changes. If i go 110 miles into the new area (hgt file area) and hit 'T' noting, no terrain is dem'd....
Anyone know why or how to fix it.
