SENC (SYSTEM ELECTRONIC NAVIGATIONAL CHART) - Abhishek Sabharwal

In order to get efficient data structures that facilitate the rapid display of ENC data,most ECDIS convert
each ENC dataset from S-57 into an internal machine language format called SENC or System ENC - which is optimised for chart image creating routines. Each ECDIS software manufacturer has its own SENC format.Consequently the SENC format may differ between ECDIS manufacturers.
