The background map cannot be displayed.
Wenn trying to insert static backgrounds, a warning is displayed:
'Cannot insert backgrounds from online sources. No maps are available for the coordinates of the window section. Please check whether your network coordinates comply with the used projection and if the selected section lies within the valid coordinate range.'
The coordinate values of the network elements do not match the set coordinate system.
Typically the coordinate values match to a projected coordinate system e.g. 'WGS 1984 UTM Zone 32N'.
Either no coordinate system was set: 'Visum' means that no coordinate system was declared.
Or accidentally a geographic coordinate system e.g. 'GCS_WGS_1984' was set.
Network -> Network settings -> Scale -> Coordinate system
the declared coordinate system has been saved.
Choose the correct coordinate system, in this example ' WGS 1984 UTM Zone 32N':
Projected Coordinate Systems -> Utm -> Wgs 1984 -> WGS 1984 UTM Zone 32N.prj
Klick OK and uncheck the option 'Transform coordinates in case of changes'.
This will declare the coordinate system to meet the real network object coordinates.
