Gobo. apologies I think I got my vectors mixed up with rastor. I think the charts I saw were Endeavour
(Raster), I was trying to encourage more names of other ECDIS approved chart suppliers.
However this is not important to me, older scanned charts are. I would love to have them as backup to my CM93 that, I called them a toy because in some areas they are woeful (cloud shaped blobs), still they are calibrated to WGS 84, certainly more accurate than the Admiralty charts I scanned and geo referenced. But my bugbear is so much information is missing from CM93 compared to older Admiralty charts.
That aside I do believe that the word ECDIS has a legal
connotation that is important to our Commercial brethren, not us. I do not know much about S57 other than its to a IMO standard. Great more is more. maybe a economic version will filter down and give me more accurate coastal detail that our commercial cousins are not so interested in (even if it was surveyed 100 tears ago), with semi-regular updating of corrections.
