About EPSG:3414

EPSG:3414 is SVY21 (Singapore TM 2021) — a Transverse Mercator projection on the WGS 84 ellipsoid (SVY21 datum) with central meridian 103°50'E, latitude of origin 1°22'N, scale factor 1.0 and false easting/northing of 28,001.642 m and 38,744.572 m. Compact bounds, designed to keep all Singapore coordinates positive metric values within a manageable numeric range.

The Singapore Land Authority (SLA) uses SVY21 for the national cadastre, infrastructure planning and OneMap, the official government basemap. The previous Kertau RSO and SVY 1948 systems are retained only in archived records.
