You would have to use Ground Control Points or re-geotag the pictures XYZ EXIF with positional information from an RTK receiver. If you don't use GCP or RTK then you are subject to a pixel error that relates to GPS accuracy. The relative information in each DEM (height of building/etc) is still accurate, just each pixel XYZ will have an error to its exact spot on earth. |
