Hello , I have this coordinate system, but I have no idea what to put for the “Geoid Height over the clarke 1866 ellipsoid” box. This is a point cloud, DJI Terra generated this coordinate system no problem, but when I bring it in here it wants this height. How do I figure out what this should be?

Bringing it into pix4dsurvey for contours.

Thank you!

Hi [christopherjacksonmvp](https://community.pix4d.com/u/christopherjacksonmvp)

Thanks for your question,

From what I can see you are using NGV29 height (ftUS) - EPSG:5702 and it’s not supported in Pix4Dsurvey:

[List of supported geoids](https://support.pix4d.com/hc/en-us/articles/5079622980637-How-to-use-vertical-coordinate-systems-and-geoids-PIX4Dsurvey#list_of_supported_geoid_models)

Analyzing the [EPSG:5702](https://epsg.org/crs_5702/NGVD29-height-ftUS.html) , It has been replaced by NAVD88 height [EPSG:6360](https://epsg.org/crs_6360/NAVD88-height-ftUS-.html) that it’s supported.

More info about the vertical CRS in Pix4Dsurvey here: [How-to-use-vertical-coordinate-systems-and-geoids-PIX4Dsurvey](https://support.pix4d.com/hc/en-us/articles/5079622980637-How-to-use-vertical-coordinate-systems-and-geoids-PIX4Dsurvey)

I hope my answer can help you, and sorry but I don’t know how DJI Terra works or how it deals with vertical coordinate systems.

All the best,  
Rafel
