QField elevation receives Ellipsoidal elevation only from Trimble Catalyst DA1 via USB Connection - Orthometric not possible

[jeanbeeckman]

Hello,

Does anyone know how to get orthometric height on QIELD cloud with a GNSS connected via USB cable. The receiver is a Trimble Catalyst DA1. The vertical grid used (.byn format) doesn't change anything because it's always the elipsoidal height collected in may case

Hi Jean,

QField was improved using external GNSS receiver those last release.

Did you have a look at the documentation Using an external GNSS Receiver

Maybe you will find your answer in here Altitude correction / vertical grid shift

Please tell me if it helps.

Best,

Lucie
