Description of CRS - AT_MGI / Austria GK| Attribute | Entry |
|---|
| Country | Austria |
| Country identifier | AT |
| CRS identifier | AT_MGI / Austria GK |
| CRS alias | AT_MGI / Austria GK extended 3 zones of Gauß-Krüger
projection, named Austria GK West (EPSG: 31254)
Austria GK Central (EPSG: 31255) and
Austria GK East (EPSG: 31256) |
| CRS valid area | Austria |

survey |
| CRS remarks | The CRS AT_MGI / Austria GK is used for the digital data
distribution (as default value) through the BEV Geoportal
www.bev.gv.at. It is based on the description of AT_MGI /
AT_TM but includes some changes in the parameters due to
the zoning, the used prime meridian (Ferro / Greenwich) and
false northing (-5 000 000 m). |
