I am looking for some libraries that can assist me in creating geotiffs from 3d polygons that becomes surfaces.
Given a set of polygons where each node is [x,y,z] coordinates, i would like to create a geotiff at a given resolution [r] that has elevation of the polygon at each sample point, such i can use it to subtract from DSM.
It is to be used to generate a surface that a DSM cannot penetrate. which can be found by subtracting the DSM from the geotiff surface generated from the 3d polygons above.
Do anyone have examples of libraries, it do not matter what the framework is - can be python or anything else.
It could also be combined to solve the real problem above such the intermediate step of creating a geotiff is not needed and it outputs the difference of the polygons to the DSM right away. Anyway, i need a way to represent 3d polygons and use them to subtract from DSMs.
(I dont want to be dependant on QGIS or other desktop installed software).
Can GDAL or PDAL solve the problem?
