Transformations are performed using open source grids from a BME (Budapest Technical University) project. These grids are not official VITEL grids and are not suitable for official land surveying work.
Rover Setup
Coordinate System
Choose a coordinate system based on the HD72
datum (such as HD72 / EOV
).
Vertical Datum
Choose the Hungary EHT2014 height
vertical datum.
The EHT2014
geoid is used to perform the transformation.
Base Setup
Your base or NTRIP service should be in ETRS89
. The ETRS2EOV
grid is used to perform the datum conversion.
When setting up a base station on a benchmark, enter ETRS89
geographic coordinates (lat/long) and ellipsoidal height in the Emlid Flow Base settings.
