I think most of us were as well rather perplexed at first.
I'm really at a loss why you get an error using USGS 2005 unless of course the DEM doesn't have any track on it or falls outside the continental United States. That file pretty much covers border to border and coast-to-coast.
I've used the Tiger data from the same source you are getting from for individual counties if I know the county name etc. and have never had that error pop up that I can think of anyway.
I remember using Hog years ago and if I recall it "seemed" rather difficult at the time. I got rather frustrated right off the bat with TransDem because running Windows 7 64-bit the first version I got after purchase (which was a couple of updates ago) would throw a Windows error trying to open more than one raster map. That was extremely frustrating lucky I had a laptop that I could put XP on and it worked just fine and Roland quickly updated and solved the issue.
But I'll outline the steps I go through just to be boring and maybe you might see something...
1. I go to the seamless server and select the area I want, I download it after changing the default to geotiff.
2. I unzip the file or files into their own directories, I open TransDem and open each Geotiff and then save it as a dem repeating for how ever many files I have.
3. I then open the dem, and then add each additional dem and till I get everything in there and then save it back as a merged dem.
4. Then I open the route and select the USGS 2005 and it puts the blue polygon line down.
5. I then go back to open route, simple route editor new route, and then go back into it a third time and select polygon.
6. Then I trace over the USGS route as close as I can using the zoom were needed.
7. Then select route, close all routes and I'm left with the route I just created which is simplistic enough to pull raster maps or map tiles along the route.
8. Then I select raster map web mapping services and get a 24K set of rasters along the route.
9. Then I close all raster maps and do the same thing using the map tile servers, saving each different set in their own directory.
I pretty much learned this from trial and error and for what it's worth I've not found too many that I've not been able to get to work. Occasionally I'll grab too big an area and due to the 4 GB limitation can't merge all the dems into one big file. But I think I picked up some of it from the documentation and the rest from Gisa's videos.
I think once you find a process that works well for you, and get over the initial frustration and learning curve, you'll be like I am and can't fathom ever creating a route without it. When I think back to some of the early stuff that I pulled, makes me cringe. I was almost to the breaking point trying to get something on the texture to be readable when it donned on me to use wire frame mode, talk about feeling stupid :hehe:
