Both ST_3DIntersects and ST_3DIntersection (with SFCGAL support)
can handle 3D space volumetric intersection.

Hi Bobb,
hi all,
https://hub.sharedgeo.org/apps/x3d/ looks great!
We have similar requirements for a 3d WebGIS.
A first prototype you can find at:
http://www2.htw-dresden.de/~s68071/3DWebGIS/
For Projektauswahl: select W3DS
and then select Historische Gebäude (Historical Buildings)
If there
Hi,
Try pg 21 of this:
http://presentations.opengeo.org/2011_FOSS4G/postgis-power.pdf
That will give you the metacode.
Overlays. (he sighs.) Be glad you only have 2 layers... .
Best,

Hey steve thanks for the book is really good as a resume, but the only
apart that it have to do
Seems like If you want :
for each little square, get the id of big square overlaping.
If this is simply this, you don't need the intersection function,
but only the intersects function :
You could do something like this
SELECT ss.id, bs.id , ss.geom
FROM smal_square_table AS ss, big_square_table
All,
I have a development team wanting to work on this, just need a funded project
to work from, otherwise it’s going to happen much more slowly as time permits.
So if you know of any projects in the works, etc. . . .

Hi list,
epsg 15948 is needed to transform from DE_DHDN(BeTA, 2007) (for example
31467) to ETRS89.
BUT epsg 15948 is neither available in spatial_ref_sys (postgis 2.1) nor
at http://spatialreference.org!!
I have about 10.000 tables in 31467, because that was standard in
germany last
I'm very sorry it is difficult to understand what you mean.
Maybe with a real drawing and link here to it, or to some screenshots?

Hey,
first you add your custom projection to qgis, so you can check that
everything is good.
For this go in the options/custom projection and add yours.
If you already have a shapefile with this projection, just import it in
qgis and save the created user defined projection.
When you know you
Sorry I'm not trying to offend you.

A topological approach would solve it.
Simplifying a polygon may overlap with the still-unsimplified
adjacent one, so you can't check after each single simplification.
You could check afterwards, at the end, but then resolving one

I am running postgresql 9.1 with postgis 2.0 in Windows 7. After
creating a dump from the database, I tried to restore on a machine

The docs don't have ST_3DIntersection, just ST_3DIntersects:

And, my 2.1.2 Ubuntu build (with SFCGAL) doesn't have the function.
Would I have it if I

You're right it's was forgotten in the doc.
