LiDAR data (.las) reference system unknown

EvaNougier — Mon, 05 Mar 2018 14:34:41 GMT

Hi everyone,

I have a problem with my data LiDAR (.las). I think the data is in RGF 93 lambert 93 due to their coordinate when I put the .las in CloudCompare. But, when I try to insert .las in ArcGIS Pro, my data is not at their "good" location in the map and when I check the properties, indeed the reference system is unknow.

How can I fixe it ?

My goal is to add a reference system to my LiDAR data in order to have the data in the good place in my map.

Thanks a lot for your answer,

Eva

You could try the Create PRJ for LAS https://www.arcgis.com/home/item.html?id=fe221371b77940749ff96e90f2de3d10 The requirements on that page don't specifically include ArcGIS Pro so I'm not sure they'll run directly in Pro.

Hi,

I try but I didn't find the appropriate toolbox to fixe my problem.

My LAS data don't go to the right place when I insert the las file.

I put in attached files the properties of my raw files without any transformation.

Thanks for your help,

Eva
