Map with slope doubled work so:
Normal calculations with scilab:
example :
highest point of map 130 mt , lowest 50 mt
scilab put at = 0 mt lowest point and ricalculations the other points, at the end new highs are
highest point of map 80 mt , lowest 0 mt
at this point I use a factor from .1 to xxx.
In this case i use 2.(only for experiment)
highest point of map 160 mt , lowest 0 mt (lowest remain 0 because 0*2=0)
With this method is possible decrease slope in a map very mountainous area or increase slope in a flat area.
I made another test,but now there are not hidden points for french.The flags are visible.
I do not know....
2 pics , i made some roads to see better terrain undulations.View from road of Belle Alliance
