I'm testing opencpn on mine Macbook to see if its fits mine needs. I use enc
charts from iENC | RIS portal Nederland
but they are still in a very preliminary state (no depth
lines) etc and mine own scanned chart set. Converted them with RasterChart2BSB to a *.kap file and implemented them into opencpn so far went all good only when sailing from the Haringvliet out to the Northsee I noticed I was still on the Haringvliet chart but on the outside of the lock at the North sea without a proper vieuw of the boys etc. fig 1 is at the Oosterschelde passing the bridge you have to switch to the next chart but on the last one is still a blank place without navigational info and opencpn switch only to the next chart if you pass the border of the chart where you where on at that moment.
the problem by hand due to drawing a route
across the charts boarders
Saving this route
as a gpx file and opening this in a text editor
Leaving the lat and lon data and getting rid of the rest will leave you with two collums of lat lon data of the route marks then completing each line so it will look like this PLY/<follow number>, <xx.xxxxx>,<yy.yyyyyy>
Open the .kap file which you draw the route outline on and select the 4 lines which begin with “PLY”
Paste the lines in this kap file you just made so it will look like this
Force a chart data base rebuild
within opencpn and voila when passing the bridge next chart will be active also. One question is remaining if it also possible that data outside the chart boarders won't show up in Opencpn
Mine thought now is it should be reasonable easy to make work within Opencpn by just making a tool like route manager and then applying it in the chart in one go. I would do it but it is far beyond mine programming knowledge.
