[postgis-users] Postgis for geology work

Hi Gus,

	These might also be useful: gdal_grid, gdal_contour 
http://www.gdal.org/gdal_grid.html  http://www.gdal.org/gdal_contour.html


> I´ve got to separate visualization and operations ( make something and
then visualize in browser or other software ).

What are you looking at to visualize 3D Models in browser? 

Map viewing:
	1. OpenLayers is 2D

	2. SVG is 2D

Globe viewers:
	3. GoogleEarth has nice 3D but is pretty much a read only globe
viewer with google terrain and has license issues for commercial users. The
models you are needing would be hard to overlay as kml polygons

	4. Virtual Earth 3D similar to Google with same problems. Low
performance on heavy external datasets.

	5. NASA World Wind - I think it has/is moving to a .NET base (does
this mean Windows only), source is available but geared to global terrain 3D

General 3D scene viewers:
	6. WPF is 3D but is still limited to IE clients and XBAP/XAML (XBAP
works somewhat like Java Web Start)
	 It is somewhat promising for IE web viewing, and could be used for
rendering gridded subsurface models and volume models. (Windows Firefox
.Net3.5, Safari plugin future? Linux doubtful? Silverlight WPF 2D subset
only)

	7. X3D what viewers do people recommend? How does X3D work as
browser plugin?

Gus,

Have you checked out California Soil Resource Lab.  Dylan has a lot of good
examples on there involving soil using Grass, R, and PostGIS and I think he
has some 3D examples although I guess they are mostly 2D.  I'm not sure it
would have anything of interest to you.  I think its worth a look if you
haven't already.

Hope that helps,
Regina

Hi Chris,

    to be honest, i´d  prefer to code just what i need! :)
I was looking for software to do those tasks and only found comercial 
software ( Rockware,Gemm, oasis montaj, target,...). What i need is a 3d 
environment, gis and  postgis interaction,with some geological functions or 
with capacity to implement those in python... Grass 6 seems to be an 
interesting option ! Do you know any geological application to subsurface 
modelling with GRASS?
Thanks for answering!


Gus
