21 | * SwissGrid CH1903 / L03, see http://de.wikipedia.org/wiki/Swiss_Grid.
|
---|
22 | *
|
---|
23 | * Actually, what we have here, is CH1903+ (EPSG:2056), but without
|
---|
24 | * the additional false easting of 2000km and false northing 1000 km.
|
---|
25 | *
|
---|
26 | * To get to CH1903, a shift file is required. So currently, there are errors
|
---|
27 | * up to 1.6m (depending on the location).
|
---|
28 | *
|
---|
29 | * This projection does not have any parameters, it only implements
|
---|
30 | * ProjectionSubPrefs to show a warning that the grid file correction is not done.
