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:

http://docs.safe.com/fme/2016.1/html/FME_Desktop_Documentation/FME_Coordinate_Systems/Workbench/coordinate_sys_custom_about.htm

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.

@jernejtekavec,

I have created a couple of custom coordinate systems for you:

Slovenia1996.SloveneNationaGrid (EPSG:3794)

MGI/gc.SloveneNationalGrid (EPSG:3912)

Please unzip the attached file into your Documents\\FME folder to add the coordinate systems to FME.

Both coordinate systems are working as expected. Could they be included in the FME release?

@daveatsafe​ Hello, could you please send me the zip in question too? I am too working with EPSG: 3794 and having issues. Thank you.

Hi @matija​ ,

The link in the post above has been fixed, which should allow you to download the definitions from it.
