I am looking for an engine / library / technic to implement a large scale 2D topographical map that will be used in an RTS game.
The closest I've been able to find is: http://stackoverflow.com/questions/263305/drawing-a-topographical-map which isn't exactly what I want..

Idealistically I'd like to have something that will give me similar result to "Google maps Terrain view", I will also need "Layers" just as with Google maps.

The game modules were originally written in Delphi but they are going to be rewritten, I don't have any programming language constraint.

Rendering your terrain (or directly from the heightmap) with contour lines should be simple, this GLSL shader should be relatively easy to adapt: gamedev.net/topic/… –  melak47 Jul 14 '12 at 21:36
Sadly as a noob it opens up so many new questions :) I wanted to avoid writing my own terrain/graphical engine and focus more on the gameplay. –  tanffn Jul 15 '12 at 8:28
Do you need B underlying height map to go along with the contours, or do you just need something that looks like a contour map? Also, does the same map get used for every game, or is it different? –  Tim Holt Jul 15 '12 at 17:36
Er, THE underlying height map not "B" - I'm lookin' at you, iPhone keyboard... –  Tim Holt Jul 15 '12 at 22:55
I want to generate a random map that the end result will 'look like google maps terrain view'. I am now looking at Amit's mapGen also not exactly what I need but its close. –  tanffn Jul 16 '12 at 7:10
