Quote:Can someone explain to me what S-57, S-62 means in layman's terms?
Both are vector graphics formats which are opposed to bitmapped BSB charts which are scanned maps/charts.
Vector graphics don't use as much space on your harddisk as bitmap charts.
But the main advantage is that these charts can be zoomed in and out whithout loosing details. Plus text or symbols are always drawn in the same direction if yoir rotate the map.
S-57 charts are non-protected charts (mainly US seas) where as S-62 are charts which are licenced by a code and are only usable on 1 computer. Most European vector charts are stored in the S62 format.
Both formats are called ENC charts and all main chart plotter manufacturers do use these ENC charts, but do include some changes (special options like 3D, Radar, special symbols etc.) so that these charts are compatible with the same make only.
As stated somewhere: MacENC uses the industrial standard that is S57/S62.
Last week I bought S62 charts from Chartworld for Netherlands and Belgium. Works fine with MacEnc.
They did send me the charts and can pay (178€ incl. VAT) later (14 days).
I think I can use these charts on 1-5 different computers! There site stated that I have bought a licence for 5 computers/users. Which is great, so I plan my journey on my Mac at home and use my iBook when sailing.
