Ternary Map Challenge: Put your learnings into practice
In today’s session, we’ll explore how to turn raw radiometric data into something clean, reliable, and ready for interpretation. Then it’ll be your turn to put those skills into action with a fun, creative ternary map challenge! Your challenge (should you choose to accept it) is to create a ternary map in Oasis montaj…

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…

Rotating Data in map view
Hello! I wish to create a map, but the grid is at an oblique angle, which will take up needless space in report. Is there a way to rotate a grid in map view, while keeping all the other map elements at the original position? Basically a diagonally positioned rectangular grid needs to be rotated to horizontal position,…

Automatic interpolation on opening grids?
Hi, I have an issue with making a constraint grid for 3D gravity inversions. I have made a blank grid with all values 1 in Oasis, then edited an area of it to be 0 in Arc. I then want to re-import it into Oasis to use, but opening it appears to do some sort of smoothing/interpolation between cells in an attempt to increase…
