[postgis-devel] PostGISplus for 3D graphic primitive

[Torsten Lange]

Dear Deni,

I found your mail in the archive. We are working at Department of 
Applied Geology at Goettingen University (Germany) with a 3D-Geoobject 
modeling system called Gocad and have of course all the problems of 
various data formats coming from environmental authorities and 
geo-consultants etc...

I thought about PostGIS as a cartridge for objects which are used by 
Gocad and other geoscientific applications - first of all: simple 
objects like points, polygones, but then also wells, TINs, and which 
would be of course a big thing even more complex 3D-geoobjects. There 
are other approaches I know of to store geoobjects for instants in terms 
of XML schemes by using an extended XQuery language. But in my opinion 
most public authorities still depend on the usual SQL-type RDBMS and it 
seems it would be easier for them to integrate those spacially extended 
RDBMS. I currently try to gather some people to initiate something in 
that direction and I hope if I find those including maybe some regional 
environmental and mining authorities which might be interested.

If I succeed in the way I'm thinking of, I could imagin that we might 
get in contact about this issue.

Best regards, Torsten
