Swiss Grid for GIS applications
The map projection and the corresponding parameters are required inputs for using Swiss spatial data in GIS applications. The following list contains the most frequently used applications.
ESRI
The following parameters may be used for older ArcInfo versions:
| Projection | OBLIQUE |
| Units | meters |
| Spheroid | BESSEL |
| Datum | user_defined 674.374 15.056 405.346 |
| Parameters | |
| 2 | Projection type <1 | 2 > |
| 1 | Scale factor at the projection's center |
| 7° 26' 22.5'' | Longitude of the projection's center |
| 46° 57' 08.66'' | Latitude of the projection's center |
| 90.000000 | Azimuth at the projection's center |
| -9419820.5907 | False easting (meters) |
| 200000.0000 | False northing (meters) |
The following parameters can be used for the ESRI Projection Engine:
| PROJCS["CH1903_LV03" |
| GEOGCS["GCS_CH1903" |
| DATUM["D_CH1903" |
| SPHEROID["Bessel_1841",6377397.155,299.1528128]] |
| PRIMEM["Greenwich",0] |
| UNIT["Degree",0.0174532925199432955]] |
| PROJECTION["Hotine_Oblique_Mercator_Azimuth_Center"] |
| PARAMETER["False_Easting",600000] |
| PARAMETER["False_Northing",200000] |
| PARAMETER["Scale_Factor",1] |
| PARAMETER[Azimuth",90] |
| PARAMETER["Longitude_Of_Center",7.439583333333333] |
| PARAMETER["Latitude_Of_Center",46.95240555555556] |
