Background

Very early on, Mike Bartholomy with the contributions of many barflies created a set of topographic maps which inset the Ring of Fire into the Thuringian landscape using USGS and German topographic maps.  While Mike’s website is gone, his work persists here.

930ft in the Mannington Map is defined to be the same altitude as 205m in the Thuringia map. The trip through space and time has deposited Grantville 78.5m lower in elevation than they started according to the map. (The Mannington portion of the map is labeled in feet and the Thuringia map is in meters.)

The first two sets of maps have changes to the maps which are not a part of the original USGS or German maps. The elementary and high schools have been manually drawn into the maps. A rail line has been added to the power plant — the significant change is that a hill was cut-through to allow for a reasonable grade. If the power plant isn’t where I speculate then the rail line will be removed. (This is easy.) The oil wells have been removed and so have the oil pumping stations because Eric says they aren’t there.

The RoF circle in these maps is 10144 meters or 6.3 miles in diameter. Really, it worked best I wasn’t just trying to get more back in 1632 and all Eric really says is that the RoF is about 6 miles in diameter. I varied the RoF both smaller and larger while trying to determine this. Another little tid-bit is that there appear to be 24 structures which will be flooded by the forming lakes. Most of the lakes won’t form very quickly since there aren’t external streams feeding them. Schwarza falls is 30-35 feet high.

The large maps are full-resolution cut-outs from a much larger map of Thuringia which I have been using. The large Mannington map is all of the data which I have spliced together. If you’re interested in getting the full resolution Thuringia map or an image not lossy-compressed send me a message.

The source data for the Thuringia topographic map before it was joined is available here. (46.0MB) I don’t recommend opening the topo.html file contained within the archive unless you have a system with about a gigabyte of RAM and lots of time to wait. Here is an index showing what numbers represent what areas: http://media.1632.org/uploads/2015/04/thuringia-index.pdf.
