I move my .tiff files generated with pix4d mapper to Autodesk software “Map3D”. It’s similar to Autocad but engineered to handle maps better.
My problem is that when I try to enter image file to Map3D it asks me whether I want to use “world file” or “image file” for insertion. One could think that the values are same but for my surprise I discovered that they differ slightly (see PICTURE1).
Img_file: 24493012.462 , 6815835.440
world_file: 24493012.453 , 6815835.450
Coordinate system ETRS-GK24 (EPSG 3878)
Why is this? I know the difference is really small but it feels bad because we are using GCP points measured with RTK-unit so it’s quite useless if this step has variance.
