Hi, I need some advice. I installed Land 10 and tried online maps of Switzerland /Swiss_Ortho_LandSat25. 
When the map is displayed, it is deformed. 
Could someone advise me how to fix the cwms file so that everything is in order?
Thank you. 
Lukas

  Hi,

  The DATUM off the other map is not WGS84 ?

  yes, the second map is datum ETRS89
  
  

  It's interesting that the map is distorted even when it is displayed separately :-(

  If you want to get the free IGN Switzerland map for Land or your GPS it is possible to create tiles with MOBAC Format MBTILE SQLITE (It's recent) the tutorial is here.

  The tiles are assembled in a HYPER MAP.

  Otherwise to have it directly in Land you have to create a script from the WMTS address available on the IGN SWISS Site

  The WGS 84 Datum projects the map onto a geoid (globe) the local Datums are generally projected onto a cone, hence this trapezoidal perception.
