Welcome to the GEOpinie RDNAP to ETRS89 transformation.

This is a demonstration application for the official transformation from RDNAP to ETRS89 and vice versa as published by the Netherlands Parntership for Geodetic Infrastructure (NSGI).

Add your points to the form below in the following format:

PointID x y H for RDNAP or PointID Latitude Longitude Height for ETRS89

Where:
