View Full Version : Basrah Map Concept

I'm tinkering with a way to create new maps more easily. Basically, it involves resizing the .xml files provided by ProSim and using paper maps as the .bmp. This might not work out too well in all terrains, but should do all right when modeling urban terrain.

The map below is of Basrah, Iraq, using the lake charles-e.xml map. Instead of being 50km x 50km, it is 13km x 19km. The paper map is one I got last year from Global Security. Lake Charles, LA is similar to Basrah in some ways. In addition, terrain can be added. Unlike the Mosul map I tested last year, this one is scaled appropriately.

Is this a good ideal?

Hi,

being the newbie that i am i can say that the map looks good for me.
Slowly understanding the concept behind maps, the way it is done looks even as good.

The drawback IMHO are the Gridlines which are modeled by the ATF-Engine (can i put it that way ?) overlapping with those from the map graphics.
At least it looks like they are overlapping in the screenshot. The idea itself is cool. I love the "original-paper-map-look" :D

DP.

If you get the grid of you bottom left corner grid of your map image and make that, also, the bottom left corner of your map image when building it, the grid lines will line up exactly

There are a couple of things you can do to make this ultra-hooah.

First, you can take the grid lines off the map bitmap if they are a distinctive color (most are). This can be done with some playing with the "magic eraser" in Photoshop. You can similarly erase contour lines, so that they don't clash with the game's.

Second, you can georeference the image so that it lines up perfectly. You'll need some GIS software to accomplish that, but some of it out there is quite reasonable nowadays. For the low budget regarding this purpose, I recommend Global Mapper, available from Rockware Software (http://www.rockware.com). It gives you a number of abilities, including the ability to georeference, merge and drape images over DEM data for a "3D" look. This would be great with satellite photography! It even speaks MGRS. Not bad for $179, and a demo is available so you can see if it does what you want before you have to shell out. You might also look at GTEP, which is cheaper, if you only want to georeference TIFF images.

Also, as for getting the map images in the first place, for US maps an extensive collection is already available from USGS. You want the DRGs, which are essentially scans of the various paper maps. Try this link page: http://www.pipeline.com/~rking/gobb.htm

Thanks for the advice.

KB,

I don't know if I can generate that 3D look since I'm using the Lake Charles xdm to simulate Basrah. That is unless I can think of a way to manipulate the bmp.

Well, naturally GM won't accept *.xdm files. But, you can just start with the USGS DEM of Lake Charles instead. Converting to .xdm is about the easiest part of the process, if the file is standard USGS format.

BTW, no need to unzip; GM will do it automatically.

Oh yeah, I feel stupid now. Thanks for the advice. I'll see what I can do.

I recommened WinTopoPro for editting DRGs - the raster vectorisation functions are very nice for the contours, and the colour "remover" is great to get rid of gridlines :)
