[GRASS-user] Import CH1903 Referenced Geodata

[Helmut Kudrnovsky]

Hi Adrian,


if you open a e00-file from the same web-site in an texteditor, you can find the following projection info:

  Projection        OBLIQUE
  ~
  Units             meters
  ~
 Spheroid          BESSEL
 ~
 Datum             user_defined 674. 14. 405.
 ~
 Parameters
 ~
 2                 /* Projection type < 1 | 2 >
 ~
 1                 /* Scale factor at the projection's center  
 ~
 7 26 22.5         /* Longitude of the projection's center (DMS) 
 ~
 46 57 08.66       /* Latitude  of the projection's center (DMS)
 ~
 90.000000         /* Azimuth at the projection's center   
 ~
 -9419820.5907     /* False easting  (meters) 
 ~
  200000.0000     /* False northing (meters)


Hope this helps to find and define the right projection to import the shapefile.

Best regards
