Last year I have prepared maps of avalanche potential by Munter’s method for Tatra mountains in Poland based on polish geoportal data. However, I’d like to apply this method to any mountains in the world, so I wonder whether there is some interface for developing new color layers on open street maps? What should I read to learn doing this? What programming language?
What I need to do is to analyze slope angle and slope direction with respect to “safe directions” of the avalanche communicate (so I need process the elevation data).
