Can we mod the contour lines?

[Terring 6,473]

if you hit Control+Shift+C, you'll notice some yellow lines crossing your map and hugging some of its mayor geographical features, such as hills and mountains. That's the contour lines, isolines of equal elevation, which obviously comes in handy for many projects.

However, I've noticed that they appear every 100 to 150 meters, which is not as often as I'd like to see. Of course I can understand that making them appear too often (say, every 10 meters) would be overkill, but still I feel that having them every 100 meters is just not as useful as it could be.

So, can we mod those lines to make them appear a bit more often, like every 20 or 50 meters?

Possibly. The contour line image is in SimCity_3.dat (TGI 0x7AB50E44, 0x1ABE787D, 0x07F94205), but I can't tell from looking at it how the game applies it.

Some time ago I made an accurately scaled map of the San Francisco bay area using a 16-bit mapmaking process and 1 arc-second (30m) Copernicus DEM data layered over 30m NCEI bathymetry DEM data.  I noticed the NCEI bathymetry when rendered using SC4 Mapper colors had a processing artifact:  contour lines!

I admit, I kinda like the visual effect even if it is a sign of stair-stepping in the underwater portions of the map.  Sadly, it would be masked away and lost once these tiles are rendered within SimCity with a proper terrain or water mod.
