[postgis-users] POLYHEDRALSURFACE WKT format and related tools?

[Stefan Keller]

Hi,

We're experimenting with terrestrial surveying data about buildings in
3D whereas there are mainly facades and the roof (but mostly no
floor).
Now I'm looking for a format to store the output which consist of 3D
planes, possibly interrelated.
So far we are visualizing the work using VRML (.wrl) format and viewers.

Knowing PostGIS 2D quite well I thought that the WKT format of
POLYHEDRALSURFACE could be a better solution.
I somewhere found that there is a ST_AsX3D(geom. precision) which
could output a VRML-like visualization format.

What do you think about chosing the POLYHEDRALSURFACE WKT format?
Are thee tools/fragments to insert and visualize POLYHEDRALSURFACE
data out of PostGIS?

Yours, Stefan
