This might not be news to anyone, since I am new to using GE. I use it with Bungee, a shareware program that costs very little and allows you much control over GE. It's pretty slick and a lot of cruisers in this part of the world use the GE/Bungee combination to supplement charts
, whether raster or vector, which tend not to be very accurate.
GE seems to be much more accurate. Some cruisers contend they can tell shallow depths within a metre or two depending on the shade. I will trust it and myself only to a point, though I have found dark water
is just that, and deep enough for my draft
. I haven't tried to load tracks yet (having too much fun getting to know openCPN
and have converted most of my library of tracks to the GPX format it uses), but will.
As was explained to me, I located dbCache.dat and dbCache.dat.index. Then saved them both in a new folder so I had them stored and they wouldn't be automatically deleted when I oversaved them. Not sure the purpose of this, but I did as I was told. I think we arrive at the same end.
I have found that when I save a file in the position where I am, the high-res pictures will be good for about 100 miles around, when I will have to reconnect to the internet
and again save my position.
But I would find it much more useful if I didn't have to periodically connect to the internet, and have thought that it would be nice if GE allowed you to download DVD-sized files of certain parts
of the world so that you could access them at will.
Sorry if this has been discussed before, but your post caught my attention. I am curious how you go about saving routes to cache. Before you set out, do you follow your proposed route
, saving images
along it to cache, and find that you have high-res GE images
along that route? How far apart do you find you have to save images? This might certainly solve most of my perceived shortcomings of GE. Perhaps I could save a couple gigs of images, store them on a flash stick, then save a couple gigs more, etc.
Also, my disk cache size is set the maximum 2000mb. My memory cache size is set to 192mb. Do you know if the size of the memory cache plays a role in determining how big an area is cached each time you save an image?
Any thoughts on this?
