TUM Open Infra Platform


The TUM Open Infra Platform (short OIP) is a software for viewing alignment and digital elevation model data.



Supported file fomats

The TUM Open Infra Platform supports several file formats for alignment and digital elevation data. It has export and import functions for IFC Alignment, LandXML and OKSTRA. Furthermore it allows to import ASCII-XYZ data and laser scan data in the LAS 1.1/1.2 format.
