Преобразование геодезических координат CGCS2000 и проекций
Точный математический пересчет пространственных прямоугольных (XYZ), геодезических (BLH) и плоских проекционных координат с трассируемыми параметрами EPSG.
Поддерживаемые координатные системы
- Связка WGS84, CGCS2000, ITRF2014/2020 и региональные эллипсоиды
- Проекция Гаусса-Крюгера (3° и 6° зоны) и проекция UTM
- Мгновенный расчет одиночных точек и пакетная обработка файлов CSV/Excel
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.
Select input coordinate system
Choose source CRS (CGCS2000 EPSG:4490, WGS84 EPSG:4326, or projected Gauss-Krüger/UTM).
Enter coordinates or upload batch
Input single point coordinates or upload a CSV/Excel file containing multiple survey points.
Choose target reference frame
Select target datum and projection parameters, including central meridian and false easting/northing.
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.
