When you import your network, Qatium will read the map projection from your files. If we can’t find it we’ll start a wizard for you to locate your network (zoom in to its location). Once zoomed in, you’ll have a list of potential projections to test and select.

Some projections end up being very similar, if in doubt select one, you’ll be able to change it later. Qatium is using the EPSG referencing to display the recommended projections. If you don’t know the EPSG reference of your projection, we recommend:

• Search for it at http://epsg.io/
• Ask your GIS or hydraulic modeling team or consultant that built the model what projection system was used
