Question regarding map

[legiox]

I am trying to create a 3-D map of the gettysburg battlefield, but I'm having a hard time finding any good topographical maps of Gettysburg. Anybody know where i can possibly find or buy some? Thanks!

Hit Google and you will find many locations on the web.

If the link does not work, google Warren Gettysburg Map Library of Congress.

I don't know how much of a change in the surrounding terrain there has been since 1800's, but you could try and search here for a DEM covering the area? They are collecting lidar data of the US for a national dataset. Not sure if its free, but sounds like it could be.

Once you had something as accurate as that as a base layer, it would be easy to add man made features.

We actually used the DEM as our base, but because of the various edits to the real landscape since then we had to use the oldest maps to 'tune' the terrain. We also went out and walked some specific areas during our team annual meetings. This allowed us to make the finer adjustments needed to correct some specific things that were just in or out of LOS that should have been the other way around.

excellent, didn't know that. You should add that (if you haven't already) to the games info when advertising!

I purchased some great topographical maps from Friends of the National Parks at Gettysburg a number of years ago. They're great maps; they look just like USGS topo maps. Here is a link to their site:

Here is a blurb from another site regarding the maps:

"Dr. Thomas A. Desjardin was the cartographer for the development and production of this excellent set of four battlefield maps for The Friends of the National Parks at Gettysburg. The four maps depict: 1 - The topography of the battlefield as it existed in July of 1863; 2 - Troop positions as of Early Afternoon July 1, 1863; 3 - Troop Positions as of Late Afternoon July 2, 1863; 4 - Troop Positions for Day 3 - July 3, 1863. The base map upon which all of the information is depicted was carefully researched and shows fences, structures, roads, etc. from the 1868-69 survey supervised by G.K. Warren for the U.S. War Department, plus information from the 1863 E.B. Cope "Horseback Survey" map as well as from information gathered from a variety of other historical sources. The maps come folded and measure 25-1/2" X 32-3/4". Follow the link from here to the Friends website then follow the links on their site to "FNPG Merchandise". These maps could prove to be one of your best investments toward understanding the Battle and the layout of the field."

Hope this helps
