How to call extension from GS script with relative paths?
Extensions can currently be called using hardcoded paths, for example: SETINI ENTRY.PARAM1=5 GX C:\Users\v.savenije\Documents\Geosoft\Desktop Applications\python\entry.py but to distribute the gs script, all paths need to be relative of course, something like SETINI ENTRY.PARAM1=5GX python\entry.py But this doesn't work.…

Discarding database changes in Oasis montaj
One particularly useful tip I like to share with new users of Oasis montaj, is the ability to quickly discard any changes I've made to a database, without having to physically delete or revert each of the channels I want to remove. When new data is written to a database in Oasis montaj, the changes are not actually…

How to get a defined boundaries of a masked grid?
Hello everyone, I masked my grid using a polygon to only include my area of interest, AOI (within the polygon). However, the grid boundaries are not well-defined. My polygon is rectangular but the masked grid has irregular or 'zigzag' outer boundaries. Is there a way to get these boundaries clear (shaped as rectangle…

Removal of Line Artifacts
Hello everyone, My gravity data has been previously levelled but I observe noises that could be line artifacts since they seem to be following the survey lines. I don't have the line levelling extension to use. Based on several references, this could be improved by applying directional cosine filter. However, the filter…

Null Data Affects the Grid?
Hi everyone, Some columns in my dataset have null values of 999999.99. I am trying to grid these columns, and they look odd. The 'background' where no acquisition lines are available, appear in single color. While the areas with lines are shaded in a different color. Could the null values be the culprit of this issue? If…

Residual-Regional Separation (FTG)
Hi all, a new learner here. I am working on FTG data on Oasis montaj and still familiarizing myself with the geophysics workflow. I want to separate the residual-regional anomalies of the FTG data. This can be done by wavelength filtering, right? However, I am confused on how to decide the cut-off wavelength for filtering.…

Drape DTM 2.0 gx
Hi, Does anyone know if the Oasis Airborne QC tool- 'Calculate Draped Survey Altitude' uses the Canadian Geological Survey's Drape DTM v.2.0 gx or algorithm? The CGS's doc for Drape DTM v.2.0 refers to drape_dtm.gx but I cannot find this gx. Just wondering if it is the same tool as found in the Airborne QC extension.…
