No, Haven't worked on the route for a few years. The problem was that when I downloaded the DEMs from the USGS for the extension down the Northfield all looked well but for some reason the last two miles were perfectly flat, no data in the file. I tried to build it up myself but wasn't impressed, so walked away from it.
Maybe put the equipment together and offer as a pack?
Odd that there are corrupted DEM's. In all the gigs of DEM I've downloaded and used to create terrain, I do not recall ever having one corrupted so that there was no data. Did you by any chance attempt to download again and try?
The equipment for the route has been in the library for years. As for the DEMs, the ones that covered Vermont and New Hampshire were fine, the ones that included the borders and anything in Massachusetts were just flat ground at sea level, they were all generated at the same time from the USGS site. About a year after the first try I did go to the site that was storing the old USGS DEMs (NED3s actually) and download the ones that had no data from the first time and just got the same thing. Never had a problem like this before myself.
