| Schematic Track Plan
| |
| | |
| {{UC description}}
| |
| Infrastructure managers use maps for the visualization of their railway infrastructure. These maps comprise:
| |
| * Geographic maps
| |
| * Geoschematic maps / drawings
| |
| ** Operational points have geodetic coordinates
| |
| ** In between, the line layout is schematically interpolated
| |
| * Schematic drawings
| |
| ** All elements have screen coordinates resulting from their complete schematic layout.
| |
| | |
| The following figure depicts an example for a schematic drawing:
| |

| A more complex real world example of a schematic track plan is depicted in the following figure:

| |
| The infrastructure manager uses data from their own data bases to visualize them in the mentioned different types of maps. If the visualizing system comprises also editor functionality, there will be also a feedback channel to import the modified data into the infrastructure manager data bases.

| |
| *IS
| |
| This interference to interlocking relates to the visualization of routes and their attributes (ATP device type, CTC handling, overlap/safety zone/slip, timers, speeds), which is demanded by JBV.
