Nautical Charts

Nautical cartography in force information.

NAUTICAL CARTOGRAPHY

The Hydrographic Institute published New Editions of the Nautical Charts of the Oceanic and Coastal Series of Angola - 72101, 72102, 73201, 73202, 73203, 73204, 73205.

In the compilation of the 2nd Edition of these letters, new information provided by the Government of the Republic of Angola was used, namely, multibeam bathymetry and the coastline collected based on satellite technology.

With the publication of these letters, the Hydrographic Institute is responding to the need for cartographic updating of the territories of African Lusophone Countries (PAL), highlighting the relevance of these letters to Angola in the regulation of its maritime space.
