Re: [GRASS-user] Plot 3D Drillholes in Grass GIS
Casey, I was very interested in your original email, so I tried to track down the GRASS modules mentioned in the paper you cited. As it turns out the authors have written several related papers. While I was able to obtain the other papers, I could not locate the software. So, I emailed the authors (Shinji Masumoto) and just got a response. Unfortunately, the authors are unwilling to release the software into the public domain. I have not specifically tried NVIZ visualization as you describe, but I think the 3rd Ed. of Open Source GIS: A GRASS GIS Approach covers how to create 3D vectors which can be brought into NVIZ to produce what you need. Regards, Tom Casey Vandenberg wrote: I was wondering if anybody is familiar with ways of plotting drill hole data in Grass (i.e. to visualize in NVIZ or to manage attributes, query etc...) based on point features with known dip, strike and azimuth angles. I have come across a paper (Development of Visualization Tools for Geologic Information on Grass GIS) which seems to do just that, however as far as I can tell it has not been released or provided to the Grass Community. If anybody is familiar with anything else, it would be greatly appreciated.

Re: [GRASS-user] Plot 3D Drillholes in Grass GIS
I was trying to find related software or a way to work with boreholes and geological cross sections in grass, not just for the drawing part but a way to use it for geological analysis. It's very sad the fact that these modules are not for public use, even with a stricter licensing than GPL.

Re: [GRASS-user] Plot 3D Drillholes in Grass GIS
Thanks for your reply to my question Ivan and Venka (and thanks for the links to the papers). If you get word on when the corresponding author is planning on releasing the above work to the grass community I would be very interested in hearing about it.

[GRASS-user] Plot 3D Drillholes in Grass GIS

Re: [GRASS-user] Plot 3D Drillholes in Grass GIS
Hi... we have worked on doing volumetric interpolation of dip and direction obtained from survey of geological strata (but if you have a lot of data coming from more drill holes the problem is exactly the same: 1) we consider the normal to the plane representing in each point the badding strata 2) we interpolate (3d interpolation with v.vol.rst) the three components (xyz) of this normal, obtaining a voxel map for each component 3) we combine back this three components to obtain a volumetric interpolated map (voxel) of geological dip and direction 4) now we can obtaine slices of this two maps but if your problem is simply visualization of the data coming from a single hole then a possible solution is to create inclined planes (small) that pass from the point where bedding has been collected. Then represents this planes into NVIZ cheers ivan Il giorno mar, 10/03/2009 alle 12.30 -0700, Casey Vandenberg ha scritto: I was wondering if anybody is familiar with ways of plotting drill hole data in Grass (i.e. to visualize in NVIZ or to manage attributes, query etc...) based on point features with known dip, strike and azimuth angles.
