Issues Importing Geosoft .GRD into ArcGIS Pro (Plugin Not Installing)
Hello everyone, Hope you’re being well. I need some guidance on importing a .grid file from Oasis montaj into ArcGIS Pro. As you may know, Geosoft grid outputs often open only as images in ArcGIS, without true raster data values. I’m trying to bring Geosoft grids into ArcGIS Pro as proper numeric raster files. I also…

How to show shapefile labels on a map in Geosoft Oasis montaj?
Hello everyone, I’m currently working on a mineral exploration project using magnetic data in Oasis montaj. I’ve added a shapefile containing mineral index locations within my study area, but I’m not sure how to display the labels (i.e., the mineral index types) on the map. Could anyone please guide me through the steps to…

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…

MVI results
MVI services posts INVERSION STATUS: SUCCESS, job closed. Previously, there would be a wayto download the clipped .geosoft_voxel files. Last Friday and today, Oct 10 and 14, I had to used my ply file to window the amp proj and perp files in the \results\ folder. No downloading these clipped files from the server anymore?

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…
