How to transform coordinates between CGCS2000 and WGS84 online

Perform rigorous 3D datum transformation and map projection between CGCS2000, WGS84, ITRF, and Gauss-Kruger grids.

  1. Select input coordinate system

    Choose source CRS (CGCS2000 EPSG:4490, WGS84 EPSG:4326, or projected Gauss-Krüger/UTM).

  2. Enter coordinates or upload batch

    Input single point coordinates or upload a CSV/Excel file containing multiple survey points.

  3. Choose target reference frame

    Select target datum and projection parameters, including central meridian and false easting/northing.

  4. Compute and export

    Inspect converted coordinates with traceable EPSG parameter lineage and export transformed results.

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.
