Roland Ziegler, the master of TrainzDEM, has kindly agreed to host a series of tutorials on his site, which are written by myself. The tuorials are primarily aimed at the novice TrainzDEM user, and specifically apply to USGS resources.
The tutorials are planned to parallel those tutorials already posted on the various websites.
The first two units of the tutorial are available now, in down-loadable pdf format.
The first unit is actually a tutorial on accessing NED data from the USGS Seamless Server.
The second covers the implementation of that data by TransDEM, to generate DEM maps.
A third tutorial centers on the developement of routes from 'historic' USGS raster maps, which are just 'old topo maps'! It explains the procedure for georeferencing these maps to recently generated DEM maps. the tutorial will be available early next week.
The TransDem site is http://forum.transdem.de/index.php?s...8411f925cb8624
It pleases me to offer these tutorials to a generous Trainz community, which has offered so much to me, over the years.
