Coordinate System Geoid Height?

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

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

Analyzing the EPSG:5702 , It has been replaced by NAVD88 height EPSG:6360 that it’s supported.

More info about the vertical CRS in Pix4Dsurvey here: 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,
