RD ↔ INSPIRE / GNSS Converter

Convert Dutch RD coordinates to latitude/longitude for mapping, DATEX II and INSPIRE workflows.

Input

Use RD New X/Y in metres for the Netherlands. The reverse conversion is included for convenience, but this page remains a practical approximation, not a certified geodetic transformation.

Approx. valid range: 0–300000 metres
Approx. valid range: 300000–620000 metres

Decimal commas are accepted. Example: 155000, 463000.

Result

Latitude, Longitude
Enter RD X/Y to calculate.
Longitude, Latitude

RD result
Use Lat/Lon → RD to calculate.
CRS explanation 
Source: RD New / EPSG:28992
Output for practical GNSS/web use: WGS84 / EPSG:4326
Output for INSPIRE context: prefer ETRS89 / EPSG:4258 where required

Compact explanation

What is RD?

RD means Rijksdriehoeksstelsel, also known as RD New or EPSG:28992. Coordinates are X/Y values in metres, used widely in Dutch mapping and public-sector datasets.

What should I use for DATEX II?

DATEX II point locations are typically exchanged as latitude/longitude, not Dutch RD X/Y. For practical system integration, WGS84-style EPSG:4326 latitude and longitude are commonly expected.

What should I use for INSPIRE?

INSPIRE context often requires ETRS89, commonly EPSG:4258 for geographic coordinates. Do not blindly label every latitude/longitude pair as INSPIRE-compliant without checking CRS metadata.

Accuracy note

GNSS, WGS84 and INSPIRE are related words in many workflows, but they are not exactly the same thing. This page uses a practical browser approximation. For official Dutch geodetic, legal, cadastral, or high-accuracy engineering use, apply RDNAPTRANS2018 and validate the full CRS metadata.

This browser tool provides a practical coordinate conversion for operational and exploratory use. For official Dutch geodetic, legal, cadastral, or high-accuracy engineering use, apply the official RDNAPTRANS2018 transformation and validate the complete CRS metadata.

Small test section

These examples are intended as sanity checks for Dutch locations, not as legal survey references.
