PTV Visum - Frequently Asked Questions (FAQs)
After exchanging the coordinate system, the coordinate transformation leads to an error message:
'Transformation of one or multiple co-ordinates failed.
Object type: Points
Object key: ...'
The set coordinate system is as stated a geographic system (which means: degrees), but some coordinates exceed the maximum of +90N or +180E degrees or minimum of -90N or -180E degrees. Probably, the coordinates of the network meet a metric (projected) coordinate system.
Try to find out which metric (projected) coordinate system actually is used, and set it to that, without the option 'Transform coordinates in case of changes'.
