ADD OR VIEW BING IMAGERY IN OASIS MONTAJ 9.4.4 MAPS
I AM UNABLE TO ADD OR VIEW BING IMAGERY IN MY MAP. EARLIER I WAS ABLE TO ADD, BUT FOR THE LAST COUPLE OF DAYS IT IS NOT. PLEASE PROVIDE THE REASONS FOR THIS. PLEASE NOTE THAT IT IS ONE OF THE BEST FEATURES OF OASIS MONTAJ AND SHOULD BE AVAILABLE. AS FAR AS I KNOW IT IS ACCESSIBLE IN OASIS MONTAJ 8.5, WITHOUT SUPPORT.…

Three Key Challenges in Wind Farm Development
Three key challenges in wind farm site development are: 1. Unexploded Ordnance (UXO) may be a safety and insurance concern for construction projects. 2. Cable and pipeline routes need to be planned, monitored and modeled. 3. A thorough understanding of the subsurface geotechnical properties are needed before wind turbines…

How to turn off floating windows - New to 9.2
Have you tried using floating windows in Geosoft? Instead of stretching the main Oasis montaj window across multiple monitors, you can drag just your map, database, or grid onto a second monitor. While I love this floating document feature when I'm working with multiple monitors, sometimes I am only working on my laptop…

depth-to sources methods: tilt angle and Euler deconvolution
Hello everyone please I am a beginner on Geosoft. I have used a satellite gravity data whose resolution is 5000m (2.5 arc minutes). I have three questions: 1. Considering a flying height of 5000 m and a suitable structural index, will the results from the Euler method give me solution depths below ground surface? 2. Are…

GM-SYS 3D - Synthetic Sensitivity Modelling Study
Good morning all, I am currently running simplified 3D wedge models approximating my geological scenario with the ultimate goal to assess resulting depthing uncertainties through structural Inversion considering the inherent input density and picking uncertainties. After running some initial tests, I discovered some…

Target for ArcGIS Scripting Capability
Is there a method available to use Python within ArcGIS to script or automate some of the mapping tools? I'd really like to be able to script the section tool to be able to save sections in separate map files (MXDs) rather than having to turn on and off dozens of layers. Anyone else have the same requirements? Govi

3D SEG-Y using external "Nav" file?
I am wondering if anyone who works with 3D SEG-Y volumes has encountered volumes "in the wild" that get their X,Y trace coordinates from an external "Nav" file? In all of the cases I've seen, either * The text header or a "load sheet" ties 3 or 4 Inline/Xline coordinates to actual X,Y coordinates, * the trace headers have…

Error 154: parse error at "GRID3D"
Hi all, I have just moved onto version 9.4 of GX developer, and now, upon running the gxc compiler, I get the above error. It isn't my code, as the same happens on the supplied Geosoft source code. The grc compiler appears to run correctly, I have checked the "all.gxh" and "grid3d.gxh" files and they appear to be normal -…

import .tiff file
We used to drag the raw .tiff file into geosoft map directly, but this seems no longer working with Geosoft 9.3. It's also not working by using the menu option 'Import ->Image (bmp,tiff,etc.)...'. Just wondering if that is due to the updates of newer Geosoft version or could anyone suggest a better way to import the raw…

Custom grid colour
In Oasis Montaj viewer 9.3 I have a grid containing position coordinates (x,y) and magnetometer altitude (z). I would like to change the grid colour so that everything under 3.5m is blue and everything over 3.5m is red. How can I do this? I've tried using the colour tool but it only seems to want to change colour according…
