EPSG:2104 Lake / Maracaibo La Rosa Grid
Projected system (Lambert Conic Conformal (1SP)) in use: Venezuela - Maracaibo - blocks I II and III. The full definition below, and conversion in one click.
EPSG publishes no simple transformation to WGS 84 for this datum: conversion works on the ellipsoid alone and can be off by tens of metres.
