I've received a .dxf file of a small area in Sicily. Now I have a problem with the coordinate system. It's not the usual European UTM or similar. I absolutely cannot find what coordinate system it is.
The extent is
-4011.0709999999999127,-4410.8940000000002328
-790.0000000000000000,-2388.5529999999998836
I have been using QGIS (without Python) for a long time and I know my way around. Here I have not found a way to get the EPSG from the metadata. or is there a way?
I googled a lot but couldn't find the system.
