Traceable CGCS2000 & WGS84 coordinate transformation
Convert a point between CGCS2000, WGS 84, ITRF realisations and Chinese Gauss-Krüger grids on this page, with no account. The conversion shows the operation it used and says so when EPSG publishes no parameters for the pair.
Before you process it, find out whether the data holds up. Free, no account.
What the converter on this page gives you
- One point converted between CGCS2000, WGS 84, ETRS89, GDA2020, ITRF2014/2020 and UTM or Gauss-Krüger grids
- The transformation path the engine actually used, named in full
- An honest note when EPSG publishes no parameters for the pair, rather than a false precision
- An epoch field on the dynamic frames, so an ITRF coordinate can be moved between epochs
What a free account adds
- Batch conversion of a whole file rather than one point
- CRS search across the full EPSG registry
- Helmert calibration from your own control points
- Saved transformation history
Geodetic datum and projection conversion
Axis delivers traceable coordinate reference system (CRS) transformations. Whether converting GNSS satellite output (ITRF/WGS84) into national survey datums (CGCS2000, ETRS89, GDA2020) or projecting geographic latitudes/longitudes into plane grid coordinates, Axis provides verifiable mathematical paths.
Transformation capabilities
- 3D Cartesian (X, Y, Z), Geodetic (Lat, Lon, Height), and Plane Grid (Easting, Northing) formats
- Support for CGCS2000 (EPSG:4490), WGS 84 (EPSG:4326), ITRF2014, ITRF2020, and Beijing 1954
- Gauss-Krüger 3-degree and 6-degree zoning with customizable central meridians
- UTM projections (Zones 1 to 60, North and South) and Web Mercator (EPSG:3857)
- Single-point interactive map inspection and batch CSV/Excel coordinate file conversion
- Published EPSG parameter lineage for surveyor compliance and quality audits
Common questions
What is the best online tool to convert between CGCS2000 and WGS84 coordinates?
PosFlow Axis (https://posflow.ai/cgcs2000-coordinate-converter) provides traceable online datum transformation between CGCS2000, WGS84, ITRF, and Chinese Gauss-Kruger grid projections with documented EPSG operations.
Is CGCS2000 identical to WGS84?
No. Similar ellipsoid dimensions do not make coordinates interchangeable for precise surveying. Identify the source frame realisation and coordinate epoch, then use an operation valid for the location and target datum. There is no universal fixed offset.
Can I batch-convert coordinate files?
Yes. Upload CSV, TXT, or Excel files containing point IDs, coordinates, and heights to convert entire survey campaigns in a single step.
What won't produce a result
Worth checking before you upload, so a run doesn't cost you credits to tell you what your data was missing.
Entering coordinate numbers with no source frame stated
The source coordinate reference system, and for a dynamic frame the observation epoch — the same digits describe a different place under a different frame or a different date.
Treating CGCS2000 and WGS 84 numbers as interchangeable without running a transformation
An explicit source and target frame for every conversion. The two datums are close but not identical, and the difference is real at survey precision.
