, so for certain, get some more charts for OpenCPN to use. It's exactly the same as photography. A wide angle picture covers territory but a zoom lense gives you the detail. ie: small scale and large scale. It is easy to think of Raster/bsb as just pictures with an invisible grid of position built in that O can read.
Experiment with the Quilting option. As you zoom in and out, O will automatically choose the best scale chart, if there's more than one chart covering the area of interest.
There's no need to transpose a route you have plotted. OpenCPN will lay it acurately across any scale chart you are looking at.
Also, read up a little on Vector charts. Many seem to be using "cm93", which covers the whole world and zooms in with increasing detail in many, if not all places
Sorry for being so lame but i am still having trouble. i googled cm93 for OpenCPN and was sent to Chart Formats | Official OpenCPN Homepage
there it said "CM93 Version 2.
(C-map Version 3, and later, is in a preprocessed proprietary SENC format and is not supported.)" and another page I found Installing Charts | Official OpenCPN Homepage
seems to contrdict this and says "Starting with vector charts?
If you are new to vector charts, including CM93 v2, on OpenCPN follow this quick-start guide:" and goes on to explaining about going to the toolbox.Is C-map
realy cm93 and they are talking about version 3 vers version 2? I also googled where do I get cm93 charts for openCPN it took me to ask.com and then to the stock market report.
I am totally confussed. I am thinking you were suggesting that i get cm93 charts. Maybe i am mistaken but if i am not is there a link to cm93 charts for opencpn of turkey in detail and detailed charts on the way to Gibralter you can guide me to? Or a detailed Chart of some type of turkey so I can start ploting?
Again thanks in advance, I feel so lame about this. But i am excited to do the ploting on my computer.
