Hey folks,
we got some 3D-surface-data in our postgis-db and we need to
simplify/generalize it. The geomtype is polyon cause we use a geoserver
with w3ds extension to publish it.
The data comes from a shapefile with x,y,z-pointdata. The points are in
regular distance (every 100 meters).
This is of course inefficient and i would like to simplify the data and
reduce the amount of points without losing information. The shape of the
surface shouldn't change to much but the neighbouring points of (nearly)
equal height should be erased.
Any hints or tips on how to do that? (ST_Simplify did just nothing with
the data.)
Kind regards,
Kai
