Hello, I just created a TIN from a LIDAR point cloud (L1 DJI). I want to export it to GIS software. This is impossible with an .xml format…  
How to do ?

thanks in advance

Camille

Hi camille,  
Esri uses a format called the Esri TIN. This is a proprietary format however you can convert the landXML file to the Esri TIN using their spatial analyst extension. You can read more about this tool in the article below.

> **[LandXML To TIN (3D Analyst)—ArcGIS Pro | Documentation](https://pro.arcgis.com/en/pro-app/latest/tool-reference/3d-analyst/landxml-to-tin.htm)**
>
> ArcGIS geoprocessing tool that imports one or more TIN surfaces from a LandXML file.

Thank you for your reply. I managed to convert it to ESRI TIN but the file is not georeferenced. Is this normal? Do you plan to offer a raster output format on pix4D Survey?

Thanking you,

Camille P.

Hi Camille,  
I had to do a little digging on the Esri site to understand why it throws an error when defining the projection within ArcMap. It appears that this is a known issue. As a result Esri has published this article on several workarounds to help correct the problem.

[Problem: Unable to project a TIN in ArcMap](https://support.esri.com/en/technical-article/000012608)

Survey is designed for vectorization and is not intended to create a raster output. If you are looking for a raster then you will want to bring the L1 dataset into either ArcGIS or QGIS to classify and generate a raster.
