Convert survey points between coordinate systems such as geographic, plane and local grid.
大地坐标(经纬度)→ 高斯-克吕格平面坐标(CGCS2000 椭球),含带号、中央子午线与子午线收敛角
| Item | Formula / Note | Source / Standard |
|---|---|---|
| Gauss-Krüger projection | 6° zones L0=6n−3, 3° zones L0=3n; no distortion on the central meridian | National geodetic specifications |
| Zone conversion | Convert via inverse to lat/lon then forward into the new zone at ~1 mm | Standard zone-conversion procedure |
| CGCS2000 datum | CGCS2000 is the current national datum; Xi'an 1980 being phased out | SBSM 2008 announcement |
| DMS conversion | Decimal degrees = deg + min/60 + sec/3600; field books use DMS | Angle-recording convention |
