Land surveying in the Netherlands: the RD grid and ETRS89
In the Netherlands the whole country fits inside one local grid: RD. That is the rule; the exceptions arrive with foreign data.
Field takeaways
- The national system is RD (EPSG 28992); cadastre and utilities run in it.
- RD is a Netherlands-specific projection centred on Amersfoort; it is not UTM.
- X values run 0-300 km and Y values 300-650 km; a value outside those ranges signals the wrong system.
- International and GNSS-sourced data arrives in ETRS89; converting to RD is daily work.
- The app opens in the Netherlands with the official system covering the location.
RD: one system built for one country
The Dutch national system is the Rijksdriehoek, RD for short (EPSG 28992). It is a projection centred on Amersfoort and designed around the country's shape; it is not part of the UTM family. Cadastre, municipalities and utility authorities work in it.
The number range tells on itself
RD has a convenient property: X (easting) values run between 0 and 300 km, Y (northing) values between 300 and 650 km. Y is always larger than X. A coordinate outside those ranges is not RD — it is ETRS89 degrees or another system entirely. That simple check exposes a file opened in the wrong system within seconds.
The relationship with ETRS89
GNSS measurements and international datasets arrive in ETRS89. In Dutch practice, moving between the two is daily work, not an exception: measure in ETRS89, deliver in RD. The official transformation is well defined and works at centimetre level.
What the app does in the Netherlands
MapLab Survey opens in the Netherlands with the official system covering the location. RD and ETRS89 sit together in the catalogue; you can measure in one and deliver in the other, or bring in an old plan and compare it with the current measurement. Output goes to DXF, KML or CSV in the system you choose.
One practical warning
Labelling an RD coordinate as "UTM" and sending it moves the recipient's map to another country. Writing the system's name into the file is a one-line job; not writing it is an hour-long one.
Try these steps on your own phone.
MapLab Survey handles RTK/GNSS point capture, drawing, area and volume calculations and coordinate conversion, then exports to DXF, KML/KMZ, GeoJSON, Shapefile, GeoPackage, NCZ or CSV. Capture, calculation and export work offline. Live NTRIP corrections and online basemaps need a connection.
Frequently asked questions
Which system is official in the Netherlands?
RD (Rijksdriehoek, EPSG 28992); cadastre and utilities run in it.
How do I tell whether my coordinate is RD?
Check the ranges: X 0-300 km, Y 300-650 km, and Y always exceeds X. Anything outside is another system.
Can I deliver a GNSS measurement in RD?
Yes; measure in ETRS89 and convert with the official transformation. The app does this from its catalogue.
Which system does the app open with in the Netherlands?
The official system covering the location; RD and ETRS89 sit together in the catalogue.
