Use OpenCPN with Saved GE Caches Offline

[yachtvalhalla]

FWIW, I've just posted an addition to my website on the above subject.

Comments welcome

..it's sure a good idea you have to split the caches up into small named bits!..My caches are too big..and the zoom levels contained therein vary too much....also,I fear the day is coming when my old version won't work online (so I better get on it..!)

Sorry ... the link in post #1 seems to be broken now.

Go to this link and look for the subject posted 12 Aug 11.

I am obviously missing something here,but why go to all this effort when you can copy and convert any GE view prior to departure with GE2KAP and save it as a .kap file in your normal charts directory. Then use Windows dual screen facility for simultaneous viewing of your nav chart and the GE view.

I downloaded and tried to use the 'Bungee' software to display a previously saved .GPX track file,but without success. The software just froze up my laptop.
The .GPX files I attempted to open,imports easily and without problems to OCPN via Route Manager.

Managed to get the 'Bungee' to work at last,using a .GPX track file I downloaded from one of the Globalstar SPOT 'Adventures',a sail from Bergen to Trondheim. Interesting way to simulate the trip,similar to the feature offered by Fugawi in their Marine ENC program.

Would be great,as an alternative, to also be able to run this simulation in OCPN on 'real' charts. Could that be a possibility?

Hi Tore,

I began a library of GE/KAP charts to use in OpenCPN. What I discovered was that the GE/KAP chart obscured the 'other' chart so you lost that chart's information. Sure, you can switch back and forth but that's not very convenient when maneuvering and want to know where you are on both views without manipulating the keyboard.

Using the Windows dual screen facility gives you both views but you won't see your position on the .kap file ... right?

Hi Terry..

Thanks for the tip re 'Bungee' which could become a very useful addittion.
As shown below,it should be possible to have the ship's position shown in
both OCPN as well as the Bungee activated GE display.

You're doing a great educational job for us mere mortals..

Hi Tore,

I've just completed an installation that gives me

MaxSea
OpenCPN
Yacht AIS-Pro
Bungee

all running at the same time. And with a com port to spare! Hope my little Atom processor can keep up with it!

Terry..

STREWTHHH!!! That IS powerful.. what size of screen do you have???

The dual screen combination I showed in my #8 should work from the same GPS with
a port splitter, don't you think?

I am also very interested in the Globalstar SPOT gps/satellite system,able to transmit
the ships position across the oceans and look forward to future developments allowing
duplex position messaging.

A netbook with 10.3" screen. A small item I've just told Greg Heppenstall (Bungee guy) about is that when using the Bungee/GE display the GE screen keeps popping up on it's own. Since on my screen the nav program overlaps the GE screen (which has a minimum width that can be set) it is a bit annoying.

(That was a simulated GPS run ... I don't usually go over land .. unless I'm flying)

Nice little application that can be used to store the Google earth cache files and enable

use of route/country data.

http://www.desert-info.ch/download/p...ffline_111.zip

"Hello,

some of You are travelling with a notebook, laptop or a car-pc and, maybe, have the

wish to use GoogleEarth offline. So, You must know, that GoogleEarth builds an

internal cache on Your harddisk. This cache GoogleEarth requires for starting faster

after a new start and it must not load all the date again. Try to start GoogleEarth

without an internet-connection. Wait, that needs some time and when arrives this

message (on Your computer in English)

You must press "No"

and than You can navigate in GoogleEarth offline. For example, You prepare a route

or a track in KML or GPX, open it in GoogleEarth, zoom in and "travel" along the

desired route. If this than is stored You can use it offline.

You also can rename the cache-files manually, but this is not very commod.

Hans-Josef M. from the Unimurr-forum has written a small program, which is dealing

with the cache files much easier. After I have tested the programm, we contacted,

phoned many times, made some changes, and this is now the result:

The GoogleEarth offline cache management

Your invited to download the program (see below), unzip and start it (the program

requires no installation). Google Earth must be deactivated.

Actually, the program is self-explaining, I still write a little guide for it.

So virginal, the program looks like after the first start. As first save your current

Google Earth cache, write in the map-field a meaningful name, if you want including

a remark in the next field.

After pressing the button Save or Save current cache appears this notice:

That can now be up to 5 min + time, depending on the size of the cache file. The

cache file may, after long use have 2 GB and are due to the peculiarities of this file

saving stop lasts so long. Please wait so long to notice the window disappeared.

So you have your current cache, a small trick to the hereafter to be stored caches for

their respective countries as small as possible to keep.

Go inn the File Manager of Windows to the following folders:

System C: -> Documents and Settings -> Ulrich (your area) -> Local Settings ->

Application Data -> Google -> Google Earth

and delete the two visible in the image files.

Now quit the program and start Google Earth again, visite the country to get detailed

data (Google Earth generates again the two cache files), quit Google Earth and start

the GE-cache-program again.

Forgive a name and saves the active cache. Since this probably less than 2 GB will

take this not too long. Repeatedly described the process of removing the two cache

files and visited with Google Earth for the next country. Repeate so often until You

have stored on the computer the desired countries.

That could now look like mine.

A rapid activation of the country is now nothing in the way. Select the desired country

and press the switch Activating or Activate stored cache.

Wait until the program is finished and then the offline using Google Earth to begin.

The download of the program

Thanks again to Hans-Josef M. for the excellent cooperation.

Regards

Ulrich

Hello ami keren,
Ulrich's program could be a very useful tool.
Unfortunately, the link to download the little program doesn't work. Could you please give a working one?
Also, I'm not sure that I understand correctly everything Ulrich wrote . Is the original German version of the document somewhere to be found?
Thank you for your efforts.
Klaas

Greg has a fix coming out in Bungee 6.2 !
