What are they? Who published them? Does "93" indicate the year of publication or what? Who owns the copyright? Who sells them? etc?

I've installed OpenCPN and got it working with some CM93 charts. It doesn't seem to be very detailed. Is that to be expected?

:confused:
 
CM 93 Charts

CM-93 format charts are now specialist commercial use only . Downloaded a set from Demonoid . Russian . Not that good .

Most of the free software ones are from the States where they have access to free charts. Its only the UK were we have to buy them :eek:

You can always scan your own charts but I have seen some . Not that good . Or find someone with a large plotter / copier and get it downloaded in a format you can import jpeg etc ..

Massive files though .......
:eek:

I have the cmap93 whole world charts updated to 2000 on cd. Well worth having if you can find one.
Here's a sample of upper Loch Sween and Tayvallich.

Slider

Have you tried the 'detail slider' , I think it's a right mouse click , it allows you to adjust the level of detail
 
I think there were some "liberated" UK/Scandinavia/Europe/Russia.CM93 sets lurking about a few years ago. They always opened on a home port in Scandinavia, and I assume they originated from there. They will not be updated, so while the rocks will probably be OK, new causeways and marinas may fool you. The detail (as already shown) is excellent where covered.
They came with CMWFW and CMapecs browser/nav progs. CMapNT mAx is the current offering I have, but it is on a plotter chip rather than laptop CD, so can't beat the system.
As to "zoom" detail layers, they are picked out on the aphabetic buttons on the upper bar. Not all levels are available throughout, but are usually there when important. (The picture above is a screenshot from CMWFW, your zoom may be different)

Mine says:

CMAP ECS
ELECTRONIC CHART SYSTEM
Version 4 – February 1999
(with revisions 2001)

It saves the last position and scale viewed and opens to the same screen.
 
I use them with maxsea, and am pretty satisfied with them. On the net are quite recent versions (latest is Jan 2010!) floating around for free download. Don't know who does those updates - but I always compare the areas where I plan to sail with the updated navionics on my iPhone, and have never seen changes not included.

I had an older version of CMAPECS that always opened with a chart somewhere in Norway but my latest version opens with the last viewed screen. I also have OpenCPN using CM93 charts but they don't seem to have the same detail as when using CMAPECS.

We are currently cruising in Norway and have run off the top of our borrowed paper chartage so are using CM93 charts with both CMAP-ECS amd Open CPN.

Open CPN is quicker to load and a better interface, but CMAP-ECS does show more detail - depth contours are numbered for example. The big advantage of Open CPN is that it will take an AIS input from our NASA AIS engine whereas I can't find a way to get cmap-ecs to do that.

We are runing both on an IEE PC with SSD and Win XP and a USB PS 'mouse' I got four yeafrs ago on Ebay, and the setup works great - we usually up under t

Most of the charts are 1998 or 2000, and although there may be occasional buoyage changes the rocks haven't moved.

I got hold of a copy of the CM93s this winter (see: torrent), running on OpenCPN. Excellent for passage planning and as a backup if the C120 goes down.

Cruising south along the Portugese coast this spring I noticed, as we were entering Figuera de Foz, that the north mole was a lot longer than shown on my 2009 Navionics chart (C120). In fact it cuts the leading line in half and was still being made.

The CM93 had been corrected and showed the mole in it's new, correct, possition. The date on the chart shows 2010.

Put that in ya pipe 'n' smoke it!

The CM93 charts I have seen running on the CMap plotter software ( definitely better than Open whatsit, but a bit dated eg no AIS) have every bit as much detail as my own C80 running whatever it is C80s run on.

As to who owns it. Well if you havent bought it, then it is pirated software usually broken by a Russian hacker.

My post in no way linked directly to anything illegal. Anyone that can use a search engine is more than capable of finding what they are looking for, if they so wish.

However, I still recommend OpenCPN, which is opensource and available for free (and legal) download.
