I am looking for a way to create isometric 3D maps based on data stored in a PostGIS database.

My idea is to create a PostGIS function that will return a SVG image like the one below. It is easy to do for a 2D image using ST_AsSVG and some math to position the map, but I don't know how to "rotate" the map to add some perspective, then "extrude" the contours to add volume. Any help is welcome !

  • For the perspective view you can use tpers as stated in this answer. It comes with proj.4 so it should be supported by PostGIS. For the extrusion part I really don't know – plablo09 Sep 2 '15 at 0:53

    Do you truly want an isometric 3D projection or just 3D? Not trying to nitpick, but those are different things and your example doesn't appear to be isometric. – Evil Genius Sep 2 '15 at 11:14
  • This is almost certainly best left to software that's meant for rendering geometry, rather than a spatial database for storing and querying geometry. PostGIS can be used to create a 3D geometry, however. – Richard Law Nov 8 '15 at 1:39
