Frequently Asked Questions
What is the difference between Gauss-Krüger Zone 3 and WGS84?
Gauss-Krüger Zone 3 (EPSG:31467) is national grid and based in Germany, while WGS84 (EPSG:4326) is geographic based in Global. Legacy German national grid (Gauss-Krüger, zone 3). Still used in older cadastral data, Bayern, Baden-Württemberg. Being phased out in favor of ETRS89. In contrast, the global reference system used by gps, google maps and virtually all modern navigation. defined by satellite geodesy and continuously refined.
Is this conversion accurate for surveying?
Yes. The conversion uses the industry-standard proj4 library with full datum shift parameters (). Typical accuracy is sub-meter for civilian applications. For cadastral precision, always verify against the official agency datum.
What coordinate format should I use?
For Gauss-Krüger Zone 3, enter coordinates as easting, northing in meters (e.g. 514500, 5033880). The tool auto-detects the format.
Can I convert many points at once?
Yes, use our batch CSV converter. Upload a CSV with your points, select the transformation, download the converted file. Free with a SurveyingPedia account.
Is there an API?
Yes — call /api/v1/transform?from=EPSG:31467&to=EPSG:4326&coords=lat,lng for programmatic access. It returns the transformed coordinates as JSON.
