Greetings.

When I import las for new project , error displayed.

 ![image](https://global.discourse-cdn.com/pix4d/original/2X/c/c7ba7ac208fa455bdc09aea31e1547d447153aec.png)

Imported Las file is Edited by TREND-POINT (The most famous Point-Cloud Editing Tool in Japan.)

I know Pix4Dsurcey need coordinate system information in las file.  
But I don’t know how to write coordinate system information into las file.

I want to select coordinate system when import las file.

Best regards.  
Seiichi Takayama.

You can use lastools - las2las to give coordinates to your point cloud

C:\LAStoolfolder\las2las.exe -i C:\pathToPointcloud\pointcloud.las -epsg 25830  
Use the epsg code of your desired coordinate system
