Geoids Download
If you need to convert a geoid to our format, please feel free to contact support@3dflow.net and we will be happy to assist you.
The following downloads are for 3DF Zephyr 7.0 and newer releases. If you are using 3DF Zephyr 6.513 or older, please head to the legacy Geoid download page.
Installation Instructions
Simply pick the “Import from disk” in the geoid selection dialog when converting from/to a coordinate system.
Doing so will open a dialog that will ask you to locate the proper geoid file. Proceed to select the downloaded desired Geoid and Zephyr will do the rest!
