THE BOLIVARIAN REPUBLIC OF BY Clifford J. Mugnier, CP, CMS, FASPRS The Grids & Datums column has completed an exploration of every country on the Earth. For those who did not get to enjoy this world tour the first time,PE&RS is reprinting prior articles from the column. This month’s article on The Bolivarian Republic of Venezuela was originally printed in 2000 but contains updates to their coordinate system since then. riginal inhabitants of modern Venezuela consisted of the Arawak, Caraïbe, and OChibcha peoples. Discovered by Columbus on 1 August, 1498, the coast of Venezuela was traced by the Spanish navigators Ojeda and de la Cosa in 1499, and Las Casas established the first European settlement at Cumaná in 1520.
