I'm a long time user and big fan of OpenCPN
. Being used to Norwegian paper charts
, I've always used to replace chartsymbols.xml and rastersymbols-day.png in s57data with the "swedish look" from OpenCPN's website.
For as long as I was using the "semi-legal" CM93 chart databases one could get a hold of on the Internet
, all was fine. The two top attachments (with the fewest depth
measurements) shows the old 2012 CM93 charts
with original (left) and modified s57data (right)
However, when using the same technique with the official charts purchased from o-charts, the chart is absolutely filled with useless symbols, slowing down OpenCPN
to the point that it's not possible to use it anymore.
The bottom two attachments shows the chart with original s57data files (left) and modified (right). And yes, that is about 150 000 pink question marks blotting out the entirety of the Shetland islands.
Anybody else encounter the same problem using the "swedish-look" palette with purchased charts from o-charts?
Thanks for any tips.
