EPSG:32655 — WGS 84 / UTM zone 55N

Source: EPSG Dataset via PROJ 9.5.1 · Updated

Summary

EPSG:32655 (WGS 84 / UTM zone 55N) is a projected coordinate reference system on the World Geodetic System 1984 ensemble datum using the Transverse Mercator method, with coordinates in metres. Area of use: Between 144°E and 150°E, northern hemisphere between equator and 84°N, onshore and offshore. The datum is an ensemble with about 2.0 m accuracy, so precise work should name a specific realization.

  • Type: projected
  • Datum: World Geodetic System 1984 ensemble
  • Units: metre
  • Axes: E, N
  • Central meridian: 147°

Example coordinates

A WGS 84 point at longitude 148.5°, latitude 24.0° (inside the area of use) has these coordinates in EPSG:32655:

Computed with PROJ using the EPSG default operation: axis order change (2D) + UTM zone 55N.
AxisValueUnit
E652,578.355m

PROJ string

A PROJ string cannot carry every EPSG detail (axis order, datum ensemble, transformations). Prefer WKT2 or the EPSG code itself.

Proj4js definition used by the converter

+proj=utm +zone=55 +datum=WGS84 +units=m +no_defs

No datum shift is needed: this CRS is on WGS 84 or a datum Proj4js treats as equivalent at the metre level.
