Feb 16, 2018 at 14:16 comment added Thoram The map shows the data from a aeromagnetic survey from 1980. The wiggles represent the strength of the magnetic field. This plot contains data from other surveys as well. I'm trying to extract the East-West trending lines which is the main focus of this map. I only have an image of this map in a PNG format.
Feb 16, 2018 at 9:48 comment added Michael Schumacher Out of curiosity, can you edit the question to describe what data is supposed to be contained in the map, and what of the data shown is significant and how? Also, do you still have the map itself and can re-scan it, or is this image file - hopefully not in JPEG format - the only surviving item?
