Dietmar,

it seems to me that CarCode suggested to team-up efforts and not to disperse capacities. Anyhow - if somebody wants to play, no issue.

Another question: I would be interested in the sources for the survey quality, especially with regards to the IHO stats. Where can I find those?

Ahoy Opie91, yes you do need to sign up (for a free account) as we need to confirm that our members are mariners and are providing accurate data. If you like to take a sneak peak you can still access some of the data by following our standard & open URLS please go to goodanchorage.com (forward slash) anchorage (forwardslash) musket-cove and you'll see an example of one worldwide anchorages.

Each and every one of them - in order to be part of this and useful to our members some of which have 11foot keels - come with depth - sat image - and refrence charts below is a screenshot - your local knowledge is very valuable to the mariner who comes after you - especially in poorly charted areas - happy to post some screenshots - but you'd miss out on all the dynamic goodies such as 72 hour weather wind swell temp cloud % forecast for every anchorage and specific maritime area information.

Re: GoodAnchorage.com Plugin – Alpha Release

rgleason,

First of, thanks for adding an anchorage! Writing this plugin was worth it after all.

After you log-in just double-click anywhere on the map. That will cause anchorages in the nearby area to show up.

Roll-over an anchorage marker to see summary (name, coordinates).

Right click on the marker and select Properties to view full description. Depending on network connection you might need to do this a couple of times.

Attached is a screenshot of your anchorage. (Hope I'm not breaking any forum rules with this).

Will work on the compilation warning.

Thank you.

Re: GoodAnchorage.com Plugin – Alpha Release

Hello MYTraveler - Good Anchorage - launched in October (after 18 months of planning). In an effort to inform mariners globally - I as an owner of a Lagoon Cat informed my peers of our free system in our group and got some flack - most of the global sailor members however seemed happy. Another member of our team & superyacht captain - new to the community aspect of the online world - "got eaten alive" by your forum - apologies - his intentions where to inform & make sure that there is always some water left under the keels. The ironic part is - that the inception of Good Anchorage - took place in country which use to be populated by - well cannibals. That is launch enthusiasm. Fortunately we are equally excited about this GA openCPN plug-in & promise to continuously improve it to make the sharing of your maritime knowledge easier & more accurate.

Re: GoodAnchorage.com Plugin – Alpha Release

Thank you bcn;


The IHO - releases data on survey accuracy in their notices to mariners -

Commercial & Superyachts are required to monitor this. - you can search for their website - the domain ends in .INT


Worldwide, the number of government survey vessels has declined by 35% in the last 30 years - contract surveys, improved equipment capability & other options have not filled the gap.
(IHO Year Books 1979-2011)
In many parts of the World the quality & coverage of hydrographic surveys require significant improvement (XVIIIthIHO Conference Resolution 2012)

Below is a screenshot of what we found at the point of inception - of wanting to make it easier for us.

If you log into our site and go to the Maritime Area of the Bahamas and read the Captains' Log you'll get to a section of Hydrography -

The current state of surveys as summarized in IHO Publication C55 'Status of Hydrographic Surveying & Nautical Charting Worldwide' Third Edition (2004) updated 27 September 2011.

1% of coastal area adequately surveyed (<200m) from shore
0% of offshore area adequately surveyed (>200m) from shore

It is only in the last few months that we have become aware of similar resources - more resources are better - that lead us to launch the Good Anchorage openCPN plug-in. Our hope is to make seafaring safer and information available to those who still sometimes gaze at the horizon when navigating unfamiliar waters and monitor their depth sounders.

Re: GoodAnchorage.com Plugin – Alpha Release

Dietmar,

Double Click works!

Here's a screenshot of the anchorage I added.

Thanks for adding to our plugin options for information!
We need to give this plugin some good exercise and advise Dietmar, so I hope Windows users will do so.

Thank you rgleason - & thank you for adding the anchorage -
but need to give full credit to our technical leader Dmitry - who is a tad south of the Kitchens Anchorage.

Looking at the anchorage information you just added and is now in openCPN - This data is very VERY good indeed - including the nearby "merrygo round "

A few questions though - what is the mayor swell or wind protection there ?
The reason is - if a mariner is nearby & needs to find a sheltered spot - GoodAnchorage & openCPN's plugin will reveal nearby anchorages and by providing this data - someone may use this anchorage to get out of worsting conditions.
NAVY BLUE means protection.

Thank you again - for adding this anchorage.

Warm regards,

Dietmar

I just compiled your plugin on a linux box AMD 64.
Just a few harmless compiler warnings, but I had this runtime warning in opencpn.log

Same here and apt-get install sqlite didn't fix it either

Re: GoodAnchorage.com Plugin – Alpha Release

Thomas, Dirk...
Code:
sudo apt-get install libsqlite3-dev
Should fix the build for you.

It does, thanks! But really, cmake should puke when not finding libsqlite3-dev...

Re: GoodAnchorage.com Plugin – Alpha Release

Doesn't it complain that SQLite was not found? But you are right, it should fail completely...

Re: GoodAnchorage.com Plugin – Alpha Release

Just published an updated Windows installer:
- Removed Windows compile warning.
- Added link to anchorage page (for photos, forecasts, reviews).
- Added instructions for first-time users.

I would classify this as a "non free" plugin.
Free used in the meaning freedom.
The plugin leads you straight to a login prompt. Unless you register and accept a draconian, typically proprietary EULA, you get no content at all.
I'm used to FOSS, free and open source software, OpenCPN is one example.
So good luck with your site and thank you for the plugin, but I'll not use it in it's present form.
Thomas

Re: GoodAnchorage.com Plugin – Alpha Release

cagney,

The plugin code is free to access, and modify (although I do need to add GNU GPL headers) and content is free to access and modify. But you are certainly free to make your own product use decisions.

Thanks for the feedback.
