I have some raster and vector data in one coordinate system and a WMTS services on another coordinate system. To go from on coordinate system to another i need to use custom transformation parameter and to go through 3 different coordinate systems and 2 custom transformation parameter because there is no transformation parameter for going from coordinate system 1 to coordinate system 3.
I can re-project data so they can fit together but i want to use it on the fly because i don't want to re-project data everytime.
For maps to fit together the workflow of projecting data is:
Coordinate system 1 (EPSG:28404) (vector or raster data) -> custom transformation parameters(EPSG:28404 to EPSG:32634) -> Coordinate system 2 (EPSG:32634)-> custom transformation parameters (EPSG:32634 to EPSG:3127 )-> Coordinate system 3 (WMTS service) (EPSG:3127)
So the input coordinate system is EPSG:28404 and the destination is EPSG:3127 but you should go through EPSG:32634 so that the maps can fit together.
Is there any way to do this in QGIS on the fly projecting?
