Hmm. my edit for the correct link didn't work. Here is the correct one: https://opentopomap.org/#map=11/49.9991/9.8383

This should take you to the area near Gemunden, Germany where TF Baum had to leave its planned route to get to Hammelburg on account of a blown bridge.

Another problem I see with importing terrain data, is all the other stuff is left out: roads, cities, bridges, vegetation and so on, so you have to figure out how to put all that onto the map.

Others on the map pointed me to Fractal Terrain which I couldn't get to work and I decided adding the above (augmenting the terrain data) was too difficult, especially trying to align the paper map with the digital data, it was just better to do it manually.

I also found 1:100000 maps to be lacking in detail and so have bought 1:50000 German maps (expensive) or 1:24000 maps (US) and do the tracing thing. USGS offers downloadable PDF maps, which can be stitched together, but the German maps are paper, so one has to scan them in order to manipulate them. Bothersome.

Neat stuff.

That subcontinent reminds me somewhat of the aliens in the movie Independence Day.

This is a fairly simple map that shows the movements of the three US Army Columns and the Sioux Village movement from April 1876 - June 26. Obviously, I am only showing the rivers. I will be adding a legend and the north arrow.

There were three columns involved. The Gibbon/Montana Column (Light Blue) leaving from Montana and moving East. The Crook Column (Orange) moving North out of Wyoming, fighting a battle on 17 June, then giving up the field and going back to Wyoming until July. The Terry Column (Black), with Custer commanding the 7th Cavalry (Yellow) moving West from Dakota and Reno's reconnaissance with one 6 Companies of the 7th (Green).

Reno was about 50 miles from the Battle of the Rosebud (the lower 3 black dots) on the 17th, having discovered the Sioux Trail and then turning back due to lack of supplies. He disobeyed orders, but had he not done so, they would not have known where the Indians were.

Terry moved West along the Yellowstone with Gibbon's column aiming to move up at least as far as the Big Horn/Little Bighorn river junction while Custer was supposed to move North along the Little Bighorn, hoping to pin the Sioux between the two forces.

Custer then took the whole Regiment moved down the Rosebud until he picked up the Sioux trail, then disobeyed his orders to attack the Sioux village. Had he followed orders, he would most likely have come across the Rosebud battlefield, but they likely would have lost the Indians again.

The map is very busy. What I am going to do next is show where units are on specific dates so one can see the progress of the various groups on a day by day display so I can display the maps in PowerPoint to show the progress of campaign.

I am not likely to try and put any indications of terrain into the map because I think it will be too busy and I have been without success in trying to do maps with the hashmarks they used at the time to indicate hills..
