[postgis-users] Re: 3d support in postgis

[Wolfgang Bär]

Hi Chris,

thanks for your fast answer.

I know that the datatypes in postgis are 2.5d. But I thought maybe 
the spatial index method is implemented with the 3d-Box datatype and 
so could also be use with custom implemented fully 3d datatypes.

But after your answer its clear what I thought - if I want fully 3d 
support I have to implement also the access method new and not only 
the datatypes and operations.

Just now I am looking at different databases in the 
object-relational and object-oriented field checking their 
possibilities for extensibility for fully 3d spatial datatype 
support for my research.

So at this time its not clear which database system I actually want 
   to use. But if I decide me for PostgreSQL/PostGIS or if I will 
try something out in PostGIS which might be of interest for the 
PostGIS community I will let you know for sure.

Thanks,

Wolfgang
