I have been given a large dataset of X,Y positions of animal movements in a generic grid system. It uses 0,0 as an origin and then position units are in feet from origin. I have the geo-referenced coordinates for the origin of the generic grid in the real world and would like to convert the entire grid to the coordinate system. One complication is that the x-axis of the generic grid is ~-38.4 degrees off of equatorial flat. They used a structure as their x-axis plane. Any tools or techniques that would enable this?
Basically the manufacturer of an animal tracking system dumped this generic X,Y grid on us and I need to overlay with geo-referenced imagery.
