TransDEM Forum

I decided to re-visit this problem where TransDEM is unable to find and crop out margins in recent USGS GEOPDF topo maps. This time I am using a 2021 USGS GEOPDF. As before, I have installed GDAL 1.11.1 from the TransDEM site (as recommended in the TransDEM documentation). As before, the neatline ...

Apparently, in addition to running TranzDEM-2.6-Setup64.exe followed by TranzDEM-2.6.8-Upd64-Setup.exe... somewhere along the way I mistakingly downloaded and installed 2.6.4.2 ground textures. That may have been the problem. Anyhow, I've since re-installed the full 2.6.8 package... and that did the ...

My texture folder looks like this. When I installed TranzDEM, I ran TranzDEM-2.6-Setup64.exe first, then ran TranzDEM-2.6.8-Upd64-Setup.exe. When running TransDEM, Help→About Transdem indicates I am running 2.6.8.

I have Transdem Trainz Edition 2.6.8.0 and TANE SP4. The Transdem Trainz PDF file, page 15, indicates I should use "TransDEM-Ground-Textures V6.cdp". However, that file doesn't exist in "C:\Program Files\Ziegler-Tools\TransDEM-Ground-Textures". The highest version I see there is V5. What am I ...

It would be great if there was a way to specify multiple, disconnected polylines in a single ASCII XYZ file. Right now, for example, if I put the following points in an XYZ file, and open it in Transdem using "Open Route", it creates one contiguous polyline that looks like an "N":

I know this is a really old topic... I'm now running Transdem 2.6.5.1 with TANE SP3. I still have the same problem where Transdem's UTM tile exporter creates a somewhat dark TGA file with occasional splotches of ultra-bright, unnatural color (cyan, pink, etc). If I go into that TGA file, in ...

Are there any issues running TransDem on TRS22?

Thanks

Same question here. I'm running TANE SP3, wondering if I should upgrade to TRS22. I won't upgrade unless I know I can utilize DEM data, ortho tiles, topo maps, geo-reference things, and create a really big map in TRS22 with 3D UTM ...

Just a small update. I've noticed that USGS 2018 "Geospatial PDFs" are perfectly usable in Transdem (and, ultimately, in Trainz) provided that I manually enter the correct coordinate system, zone, and hemisphere, and manually crop the margins. In other words, I can use the new maps. The process just ...

Thanks. Here's an example, a USGS 7.5 minute map for Felton, CA published in 2018...

Normally, the process I follow to utilize a topo map in Trainz starts out like this:

1. Download a GEOPDF from the USGS National Map Download page
2. Open it in Transdem (Open Raster Map)
3. Mask the margins (click "Define Transparent Margins with Polygon Mask" twice)
4. Convert to UTM
5. Save the ...
