I'v got a detail map for an event as PDF an made an openlayers slippy map with Maptiler. I now need to place markers at the position of gps/gsm-trackers, which store their coordinate on a server.
The map's north isn't at top and i need some kind of formula (projection?) to translate the gps coordinates to the coordinates of my map.
Is this somehow possible, e.g. via. 2 points where I know the coordinates in both systems?
I don't expect a finished solution but maybe you can give a hint where to start, I've no idea how to do this.
Example: GPS 48.26771, 16.36882 (somewhere in Vienna, Austria) in my projection is 0, 0
GPS 48.26673, 16.3696 is 100, 0
