Hello,

I am a researcher from Slovenia. I'm having huge trouble working with Slovenian datasets,

as they are in EPSG:3912 or EPSG:3794. These two systems are not supported by FME.

I solved this for shapefiles by using ESRIReprojector. But it does not seem to work

with las datasets.

I am trying to extrude footprints using LIDAR data and convert that to KML, which needs WGS84 data.

Is there a sollution? I am quite surprised that FME does not support all EPSG projections.

I even tried to add custom coordinate system and was not successful.

Regards!

Jernej

You may need to add your coordinate systems:

Oh I see you tried that.

ArcGIS cannot reproject LAS data sets, but you could convert them data to point and back after reprojection.

Hi @jernejtekavec, You are on the right path that is to say to add the custom coordinate systems and then reproject. I would advise you to contact support for some help on introducing the coordinate systems.
