If we’re using our laser scanner, we get two points from the mine surveyors, one where the scanner takes it’s measurement and one at the “back site” or “reference”. These are given in the mine’s local coordinates and used in the import into the blast design software. The total station exports an FSC file.
With a drone, we’ve used Drone Deploy in the past, putting out ground control points that are surveyed by the mine. We use those points (given to us in the mine coordinate system) with the Drone Deploy software to get an LAS point cloud.
For now all I want to do (if it’s possible) is get a point with the Emlid and convert it to the mine’s grid coordinates instead of relying on the surveyors.
They must be doing this already but using Trimble.
How would they be doing the conversion?
This is a large mine and does get aerial photogrammetry on a continual basis. I should try to get some information from that service provider if I can. Good idea.
