I am trying to convert some DEM in .tif image to polygon geometries representing 3 dimensional triangles that is: Well-known text (WKT) - 3D (x, y, z) https://en.wikipedia.org/wiki/Well-known_text



I was able to use SAGA to convert my GeoTif image to TIN, but what really wanted is a WKT format as stated above.



How do I do this is in QGIS, SAGA, GDAL, PostGIS or any other open source solution?






gis postgis gdal wkt
