TransDEM Forum

Track sits on the terrain as it should in 19sp1, but not in 19sp4. I never installed sp2 or sp3.

Welcome Franck,

I'm confident that you will enjoy using Transdem once you work through the tutorials and then start your own projects. Since it's been several weeks since your post you may be busy enjoying Transdem already.

I now have a much nicer computer than originally mentioned and use Trainz ...

Hello BraselC5048,

As I understand it, TransDEM can adjust the route's elevation and edit the coordinates of a route's origin marker only on routes that you imported into Trainz via TransDEM. The TransDEM documentation will confirm that. However, this will only work on Trainz version TANE sp1 and ...

Matt,

In Trainz surveyor, from the object splines tab, you can use the "split spline (Q)" tool which will disconnect the splines from each other and relax some of the odd angles that resulted from Trainz connecting them together.
Then you can manually reconnect the most important splines that might ...

Thank you. I had not even thought of checking the NAD27/NAD83 specification with the USGS GeoPDFs. I'll try using the OSM tiles if they are more consistent with the NAD27 specification.

I'm not the most sophisticated TransDEM user. I love the ability to import terrain into Trainz, it has made a ...

Usually I get my DEMs and rastermaps from USGS The National Map client here in the USA. Often using the 1/3 arc-second DEMs. I try to be very careful arranging the mask to remove the geopdf borders, usually magnifying the map to carefully place the mask corners. Of course I use the convert to UTM ...

I may not have had everything aligned correctly.
My edits in the .str file brought the poly lines in line with the DEM terrain.

geophil,

Thanks for the tutorial on installing JOSM and instruction on how to use that to transfer data from Open Street Maps to TransDEM. Being able to do that for a railyard saved me days of struggling with paths and polylines. I'm a slow learner, but everything worked when the directions were ...

Paul,

Thanks for sharing the website. Looking at a few of the abandoned lines that I've worked on which the tracks have been removed, it seems to me that the poly lines are drawn in using a best guess. I believe that you will need to reposition the track in Surveyor to adjust the grades. It will be ...

I'm late to this discussion, I don't know if I'm helping much.

If you are using Map Tile Servers and the "Map along a path" mode, you have probably seen the ".lgb" files that are produced. These are just a text file list of the Geo-referenced Map Tiles that TransDem reads to find the tile images to ...
