This week on Luckyfish, we're diving right into
some of the free technology that's available to
aid navigation for cruisers now quick disclaimer,
these are aides only. There's no substitute for
keeping a sharp lookout on the bow. If this video
isn't of interest to our regular subscribers, fear
not, we're still doing our regular blogs on
Fridays, right? Let's jump right in. Yeah.
Satellite images can be really useful when
electronic software like Navionics CMAP Garmin and
even British Admiralty charts are unreliable.
There's a ton of advice out there about getting
satellite images into open CPN. But most of it is
outdated. I've spent a while going through it all
and sifted it down to a fast track way of getting
them installed. It's actually pretty simple. There
are links in the description for all the downloads
you need to get started. And I've also given you a
text summary of the instructions in this video to
make it easy for you to have a ready reference.
Don't forget to subscribe to our channel. It
really helps us to go on sharing.
Firstly, install open CPN. Now go to sass planet
in the link provided and download the zip file.
Find the file and downloads, right click and
extract to your root directory. You don't install
SAS planet and state. Copy the executable and
sinned to your desktop. Double click the icon to
open and scroll through the list of imagery
available. SAS planet has done all the work for
you. Linking to Google maps, Google satellite
images, satellite images from Bing sonar charts
from Navionics and many more.
Move to your area of interest and choose what
imagery gives you the best detail zoom in and find
the limit where no more detail is offered.
The zoom limit is shown in the bottom left hand
corner. I find 18 is about the limit for satellite
imagery, zoom out and choose a broader zoom level.
For general scale viewing 14 works pretty well.
Now I go to operations selection manager and
select polygonal selection. Click the battery of
the area of interest and click the green checkbox
to finish.
Now with selection manager, open on the download
tab, select zoom levels, 14 and 18. Make sure your
map overlay is set to the imagery you chose in
this case. Bing satellite maps and click start.
Now, we need to export this cashed image as an
MBTile file. This is a high resolution geo
referenced database that open CPN can read, go to
operations, selection manager and select last
selection. Open the export tab. Choose the MB
tiles. 1.2 option. Go to the save to box and
choose the directory where you store your charts.
Check the zoom levels you used previously. Leave
everything else on the defaults and click start
the export. Doesn't take long.
We're almost there. Now start OpenCPN go to
options and main chats. Add the directory. You
just stored your MB tile file. If the directory is
not already there, click scan charts and update
database, click apply and vain. Okay. You will see
a red box outlining the satellite images. You just
installed. Select the image layer to view your new
satellite imagery, zoom in to see firstly, your 14
level zoom. And then you are 18 levels. Zoom pan
around to confirm you have what you expected.
