With regard to the sectoral plan of railway transportation the cartographic basis for existing rail infrastructure shall be adjusted. Basis for the project - data forms the "Database fixed assets (DFA)" (digitized and attributive data) the project has received from the Swiss railways. For present purposes, the data, which reflect to the individual rail track beds have to be simplified. In addition, it is not apparent from the original data, whether it is open routes, tunnels or bridge portions. This information can be seen from another record of the Swiss railways.
The objective of the project is preparation and updating of GIS data to railway lines and stations as a basis for the sectoral plan of railway traffic. The GIS data contain data on population and land use. Project conducted analyses of the potential for further development. The data are to be prepared in a similar way as already published traffic map. Data can be created in an updated form with little effort.
