Drickets: thanks for the compliments. I'm sorry I didn't see your post before.
I used wink to make the tutorials, which is great for a freeware program but it has limitations and it was a *learn as you go* kind of process for me. Rewind and rewatch if you can. If you are stuck with directions on one part or the other, just ask and I'll see what I can do to point out what I was doing at the time (that is, if my old memory serves me well).
I was also asked about the catalogue (or what the other vectors mean in this example). For Canadians who are curious as to what other vectors might work, look at this catalogue here:
http://ftp2.cits.rncan.gc.ca/pub/canvec ... gue_en.pdfAs I explained in the tutorial, the best (and pretty much the only) vectors one can really use in transDEM/trainz are:
- rail
- road
- watercourses
- powerlines
- trails
- walls/fences
I noticed one can also get gas lines, but I didn't feel that was worthy of being included (usually gas lines are in thick underbrush or underground anyhow from what I've seen). In rural areas, this may not be the case, but I never get gas lines when I make Canadian DEMs now.
There
may be other vectors you can find that are of use, but note that many of the data files you get are not
vectors, but are rather
points. For that reason, you won't be able to open them in transDEM and can't use them. Look through the catalogue and see if there is anything that tickles your fancy (look in ENTITIES). Then find that item and look at the summary at the top. Look at the geometry column. If it says line, it
might work. If not, it definitely wont!
In my experience, I only needed the 6 paths mentioned above anyhow.
For American DEMS, I only usually try to pull major roads (interstates I think?) and rail, although there is probably a lot of data you could get there too (I suspect maybe powerlines and watercourses, both of which I think are quite important).
