how to make a rectangular map of polar region
Hi all, I'm wondering how to make a rectangular map of Antarctica region with Lat and Lon labeled. When I first created the Map, I used the Lat and Lon limit to define the specific region that I'm interested in Antarctica, but it will give me a conic shape of map. If I created the map by defining the X and Y limit (from…

Oasis Montaj Project file (.gpf) not saving/updating
Running version 8.3.3, which has started to not update an Oasis Montaj gpf project file via File > Save. Saving a new gpf file each time (File > Save As) results in all current settings/loaded data/maps etc reverting back to a previous save. So I get a new project file, but have to reload all my data files in again, which…

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…

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
