Maps and geodata
Distribution of geodata at EPFL
Geodata from different institutions are made available to the EPFL community.
Students are asked to address their questions regarding both the geodatasets and the GIS (Geographic Information Systems) software to handle them to their course assistants.
For an initial training on geodata and GIS, 2 references may be suggested at EPFL:
- ENAC offers an introductory course “Geographic Information System” in the form of MOOC (Massive Open Online Course) on the Courseware platform.
- For architecture students, the TUTO-cartographie page provides tips on how to use geodata in architecture and urban planning projects, including how to use it with QGIS software (in French only).

- A personal account must be created using the EPFL e-mail address. The data can then be ordered with the discounts (or free of charge) for research and teaching. To do this, in step 2 of the order, tick “Order for a third party” and choose “EPFL” from the drop-down menu. Specify the name of the project and the person in charge (or the professor for student work).
Any order placed must be validated by the ENAC correspondent, who automatically receives a request for validation by email for each order. The invoice for the paid data is sent by the ENAC correspondent to the person who placed the order.
- Features: search, visualization and geodata order (various formats)
- Support: https://viageo/support
