FS#2686 - Enabling the import of GeoTIFF files with their inherent geolocation
It would be great if it were possible to import GeoTIFF files into QCAD with their specific geolocation. Currently, they lose their position and size during import. It would be a very valuable feature and probably not too difficult to implement.
In the QCAD forum I had a discussion about that topic with CVH and he had some valuable insights which I like to cite here:
“[...] Since we can create Map Tiles from drawing data (Tutorial) it would indeed be beneficial that bitmap data could be imported correctly.
Because the GeoTIFF format is fully compliant with TIFF 6.0 it is simply imported as a bitmap.
The question remains if QCAD is really fit to use it as a GIS application.
I assume that one can extract the left lower position and scale by other means. With the corner positions for example it should be possible to scale and place the bitmap correctly.
Then it should be as simple as adapting the Bitmap entity properties in the Property Editor after insertion.”

Sven,
It is not entirely correct to state that GeoTIFF files lose their position and size.
As replied in the topic:
Because the GeoTIFF format is fully compliant with TIFF 6.0 it is simply imported as a bitmap.
... As a normal bitmap entity from a file in the TIFF format.
I did not imply that extracting geospatial data would be easy.
But I assumed that one can extract the left lower position and scale by other means.
... Using well-equipped third-party applications.

Hi CVH,
thanks for the clarification! I really hope that this feature can be implemented in the medium term, as it would make my work much easier!
All the best,
Sven
