[postgis-users] Postgis for geology work

[Luigi Castro Cardeles]

hi,
you can see x3d for 3d visualization at www.open3dgis.org. It uses postgis
as backend for data, and web browsing for viewer.

> Globe viewers:

> viewer with google terrain and has license issues for commercial users. The

> General 3D scene viewers:
