Points to raster

Algorithm

The Points to raster operation rasterizes a point map. The output raster map always uses the same domain as the input point map. The user has to specify the georeference for the output raster map.

Process:

If the chosen point size is 1, then for each point, the corresponding pixel in the raster map is found; this pixel is assigned the class name, ID or value of the point. Other pixels obtain the undefined value.

If the chosen point size is larger than 1, then a square is drawn around each point with the specified size in pixels. All pixels inside this box are assigned the class name, ID or value of the point. Other pixels obtain the undefined value.
