The rasterization of points, lines and polygons went nicely with -burn 1
-add to a discrete heat map. Thank you, Jukka.
Particularly we where happy with the line density, but have a follow-up
question:
What does the raster values represent?
We did a vector polygon grid test clipping up the lines,
I think of create a discrete raster from points burning the number of
points of each cell into the band value. In the manual at
http://www.gdal.org/gdal_rasterize.html I figure out, that the -add switch
could be the solution. But no value has to be set unlike -burn or -a
switches.
What is the synt
I try to perform a vertical transformation from WGS84 ellipsoid heights to
geoid MSL heights on a Geotiff with a geoid GTX raster translated from
Geotiff.
