Convert coordinates from MAGNA-SIRGAS / Colombia Bogota zone (EPSG:3116) to MAGNA-SIRGAS 2018 / Colombia Bogota zone (EPSG:11116) — official EPSG transformation parameters, accuracy and area of use, with a free in-browser converter.
MAGNA-SIRGAS / Colombia Bogota zone (EPSG:3116) is the workhorse projected system of central Colombia — a Gauss–Krüger zone with its false origin (1,000,000; 1,000,000) at Bogotá on the MAGNA-SIRGAS datum adopted in 2005.
MAGNA-SIRGAS 2018 (zone EPSG:11116) is Colombia's updated realisation, aligned to ITRF2014 at epoch 2018.0. The frame update shifts coordinates only centimetres to a few decimetres, but official IGAC products and new surveys reference the 2018 realisation.
The published EPSG operation converts directly between the two Bogotá zones, preserving the familiar easting/northing structure while updating the underlying frame.
