We have tried and tried, downloaded the geoid, making .prj files, and we still have no solution
We have drones that geotag photos using rtk, accuracy less than 20mm, an we would like to transform the coordinates into the correct Irish Transverse Mercator, with Malin Head Datum, before aligning them
Even after the downloading of the goeid model osgb36_osgm15.tif there is no improvement, still the tranformed coordinates are off by maybe 50 meter in height
Can some help us please??
