I know Curt did a Fallujah map a while back you might be able to get from him.
Otherwise, you can make maps yourself. To get the data, I purchased USGS SRTM (shuttle radar topography something-or0other) data in DTED format, and then converted it to USGS DEMs, that I used to produce the maps.
You can purchase this data here:
