I was wondering if anyone could enlighten me about how
exactly the v.to.rast function works. I would like to turn a
vector layer of polygons into a raster layer. Basically, my
layer shows where a species occurs (the value for the areas
where they occur is 1). When I transform this vector into a
raster file, how does v.to.rast decide what raster cell
becomes 1 versus which becomes a 0? Does it depend on what
percentage of the raster cell is covered by the polygon, or
does the cell get a 1 assigned to it as soon as the polygon
transects it at all?
If I recall, that is explained in the help page for each type.
Feel free to point out the paragraph there that needs to be
expanded.
