GUESS WHAT!!! Im so excited that I finally got Hog to work for me. The only thing I have to know is how to merge the DEMS so I get the one contiguous route from Lake Placid to Tupper Lake.
Merging DEMs is an easy process. On the toolbar is a button labeled "In<->Out" When you click that, a Data Manipulation window opens, with an option to Merge on the top. Put each DEM in the list until they're all there, then click "Cancel". The window to complete the merge will open.
