- NHO`s are National Hydrographic Organisations.
- RENC`s are Regional Electronic Navigation Chart Systems.
- Whereas CMAP,TRANSAS,MARINE PRESS are the main distributors.
- Lets understand the above chart , IHO is the governing authority under which the NHO`s of various countries are working.These NHO`s , survey and collect their own data and send it to the RENC`s i.e UKHO,PRIMAR which in turn compile these datas,process them and then distribute it to the respective distributors which in turn sell those charts to us on ships.
Any suggestions/comments are most invited......
Cheers....
