CM93v2 chart download

They're also still a CMap product, even though they haven't been updated since 2011, so folks are cagey about posting them online.



Because of this, we've been making our own extremely accurate & detailed charts, using SAS Planet & Sat2Chart. The tools & data are all free on the internet, but it does take a lot of time, internet data, & a Windows computer. The charts themselves can be used on any computer that runs OpenCPN, but the tools to make the charts only run on Windows.



The available chart data currently includes Navionics & CMap marine charts, which are reasonably accurate & have depths. But we actually prefer the satellite imagery from ArcGIS, Bing (MSFT), Google Earth, Nokia, etc. These are amazingly accurate, with max errors on the order of 3m. Superb geo-registration, & they show near-shore reefs & shallows, including the GBR. They don't show everything, but where they show something, that's exactly where it is.



We've recently put together a How-To page on Making mbTiles, which is a chart file format that OpenCPN has been able to use for a couple of years, since v5. It's written so even a novice can make high-quality navigational charts, & we also show you how to use the automation provided by Sat2Chart to get your computer to do the hard work while you sleep (or do something else).



The page is only a few months old, so we encourage folks with questions to contact us. The only silly question is the one not asked, & if you have questions, it's a sure bet that others will have the same question, & we'd like to address those in the page itself.



Good luck!

Thanks Jon.

Your info page is really helpful. Finally I understand what Sat2Chart does.

I have sucessfully used SASplanet before, but did not understand what Sat2Chart adds in functionality.

Great info!

Those appear to be the 2005 version. Try this for the 2015 version:

Biku, the CM93v2 charts haven't been updated since 2010, so they're at least 13 years old. There are certainly no 2019 v2 charts.

CMap switched to their v3 charts in 2011. They're much better than the v2 charts, but they're encrypted. But even the v2 charts are not public domain. Many people copy them, but that's not strictly legal. And they're not very accurate, so using them for any commercial purpose is pretty dodgy.

Downloaded the file, and unzipped... Is there another step? Can't seem to recognize the charts.

You have to put them in a folder where OpenCPN can find them. We create a D:/Charts folder, & we put our charts under that, arranged in folders by County/Area. Then we point OpenCPN to just the folders we need.

If you're going to be doing this a lot, you should develop a system that works for you. OpenCPN will only look for charts in the places you tell it to. Otherwise it could drown, as we have several hundred Gigabytes of these types of charts, available for cruisers to download at our Chart Downloads page.

Did you add the directory to the unzipped folder in Options/Charts/ChartFiles?

Did you try the download listed below.

You will need to unzip with 7z, Google for it. Warning, the download is 1GB.

Also, sources of free satellite charts that work in OpenCPN are found here:
https://svsoggypaws.com/SatCharts/

Be sure to check the "Other Sources" link on that page. Lots more from other people.
