The Nigerian Navy Hydrographic Office (NNHO) has also commenced the production of the electronic versions of the paper charts produced so far. This is also part of the National Charting Scheme developed in 2018 by the Navy (Nigeria’s Charting Authority); indicating the survey and charting plans for the entire navigable waters in Nigeria. The NNHO has therefore produced three cells which can be procured from ICENC's value added resellers.
