How do I find a projection to a target CRS (Coordinate Reference System) based on a number of reference points?
Lat Lng -> Unknown CRS (X, Y) 29.999999999999456, 10.0 -> 0, 0 29.999942188937776, 10.099416075499747 -> 10000, 0 52.51051013417886, 13.430682115106462 -> 229459, 2511140 52.420591784398034, 12.98406698769891 -> 200000, 2500000 52.44802435357121, 11.492633733515229 -> 100000, 2500000
From the data above it seems, the unknown CRS has its origin at 30.0, 10.0 and the unit is in meters. My closest guess based on the tools recommended in related questions are:
Esri:102014 - Europe_Lambert_Conformal_Conic
Esri:102031 - Europe_Equidistant_Conic
However, trying to transform the coordinates using the CRS above does not yield the correct target reference points.
Disclaimer: I have read the related questions (Determining unknown Coordinate System using QGIS? and Find CRS (coordinate reference system) based on known location and coordinates?)
The EPSG-Registry and Projfinder tools recommended in those questions did not yield a result.
