Hi! I will highly appreciate your help in matter that I am struggling with since few days. I would like to create a hazard map of selected area. I read that in order to do that, I need to create a raster and assign the values to each cell (and later add colors). I don't want to convert selected polygon to raster because I would like it to be visible when selected ( I would imagine it like showed on image in attachment). The process I started by creating an extent of the polygon in order to define Xmin, Xmax, Ymin and Ymax for future raster (see attachment). Later on I tried to calculate a length of raster sides and its area. I though that thanks to that I will be able to define cell size. Nevertheless when I run a script I receive errors about wrong parameter. I have to say that I am quite a beginner in python and I really don't know what I am doing wrong. I tried to change a code using many examples that I found but still errors occurred. Many thanks in advance for any opinions, suggestions, tips and comments!.
Regards,
Paulina
