In qgis in the raster menu there is an item "convert vector to raster".
This behaves strangely - I do not understand how it is supposed to work.
I can select a vector file, an attribute and an output raster. But, for some reason the output file is only accepted if it exists and even if I select an existing raster nothing seems to happen.
Also I do not understand how the program knows what kind of raster to create, what cell-size, projection etc.
How can I convert vector to raster?
