[postgis-users] Raster data questions

I want to use PostGIS for handling 3D cubes but I couldn't figure out how
to do it from the manual.

The main tasks I want to accomplish are:

1. Import a 1D char array file (grey cube) into a 3D cube.
2. Retrieve sections from the cube, where a section is defined by a domain.


Given a file of 1024*1024*1024 bytes, I want to import it into a cube with
the domain [0:1023, 0:1023, 0:1023]. Then, select the sub-domains

   -  [100:200, 100:200, 0:100]
   -  [0:1, 0:1023, 0:1023]

Is this possible using PostiGIS? If yes, are there any detailed tutorials
which explain how to do that?

Thank you!

Best regards,
George Merticariu
