How to create new layer on the map - avalanche risk potential


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).

Best regards,

OSM does not contain general elevation data. There are a few features with point ele tags, but the structure of OSM data isn’t suited to storing rasters and generating them is generally beyond hobbyist which make up the bulk of contributors.


This seems a general GIS question, Openstreetmap forum is not really the place to ask.
You’re maybe wanting to look for information on digital elevation model (DEM). Qgis may also be a tool you’d like to learn how to use.
