We use vector-charts. You probably wonder yourself why?
Well, raster-charts are what in US we are used to, isn’t it? They are the regular Nautical Charts, as we are used to see since ever, simply scanned and “transposed” in a digital memory. Fast to produce and good to make us feel “at home”.
But what happens if we are sailing South and we want a Course Up display? All writings and information are upside down. A bit uncomfortable...
Again, what happens if we are sailing in a complicated area full of batimetric lines, forbidden zones, light houses, buoys and more and more? Again… it’s confusing but we feel home, it’s what happens with a physical Chart.
Let’s try to change mind, we are in the third millennium, we can do something better, much better, by using vector charts. They are much longer to be produced but this just matters to instruments makers or specialized electronic charting companies.
They are wonderfully flexible. Let’s see some examples.
This is a bit complicated zone, we well know. A bit confusing, isn’t it?
We just want to see better the batimetric lines? Good, we hide the spot soundings, buoy, lights and bottom type.
And now we display the place names and we sail 120° in Course Up mode.
The writings are all standing upright. We don’t need to get crazy understanding what’s on the screen. So cool!
Well, these are just examples. A good sailor would leave some more information on the screen: buoys and lights are always better to be displayed. What’s important is that we have been able to show you the extreme flexibility of vector-charts versus raster-charts.
Now, are you still sure that raster charts are the best choice?
Probably not. You just want to discuss with us a bit more on this or other marine navigation matters?
