sindbad7,
these charts are obviously made in Macromedia Flash and I do not know a tool to download them for your computer. You may use a screenshot tool only to keep them for you. My screenshot tool saves them in tiff format and you may convert it to kap when you know the coordinates of the chart. See example below from visitmyharbour.com:

Thank you CharCode..
Yes I am aware of that,just very tedious having to collect a large number of tiles for later assembly. However,you pays your money,(or not) as the case may be. he he
I was hoping there was a smart way to alter a 'pannable' display to one using scrollbars, where I could use my bi-directional Snagit9 screen capture.
Thanks 'depons' for the Firefox tip. Works great on some pages.

You are a victim of nasty proprietary crap: that page is a flash application. I know that there are tools to snatch flash media, but I've never used one, so that's the end of my wits. The only thing you can do is pan around, take screen dumps, and then labor to paste them together.

You can amend the source page on some of these flash tiled map components to increase the dimensions the flash component is rendered to. That can give you a bigger area to screengrab, but you are still going to be screen grabbing and then joining images (to get a good sized chart downloaded at native resolution).
Regards,
Mike

hi,
I am new here. I am using OpenCPN and cm93/2 maps I downloaded fron the Russsian site.
All is OK but there are no place names on the charts. Rightclicking on a proper area does come up with the area place names so the data must be there. Is this normal or am I doing something wrong?
regards

Please read the first paragraph on this page: Vector Chart Display | Official OpenCPN Homepage, and why not look through the rest of the documentation wiki!

Make sure the 'A+' icon at the top is engaged.

I still use paper charts and paper cruising guides. I have sailing charts, harbor charts and coastal charts stacked up in my pilot berth.
I use the sailing charts to plot my route so I can get the big picture. I transcribe the waypoints to my navcomp and zoom in, looking for any details I might have missed on the sailing charts.
I do the same with harbor charts. I like the double check and the fact that when the navcomp breaks, pencil and paper seem to do just fine.
To me, the biggest problem is the cost and reduced availability of paper charts. Once upon a time, electronic charts were obscenely expensive and paper charts cheap. Today, as chart plotter manufacturers scramble for market share, the prices of electronic charts have dropped significantly. With the NGA/DOD declining to make their charts available to non-military mariners, the cost of paper has risen and the choices reduced. But that doesn't negate the reason to carry both paper and electronic charts.

all it takes is one wave to crash down the companion way, or blow out a window of the bridge, or a blown battery block mid-passage, and all our fancy electronic gimzos and modern crutches are toast. (except for the backup handheld waterproof vhf and gps in a ziplock bag in the back of the drawer of the chart table of course, but when's the last time the batteries were changed?)
In a newly commissioned navy boat down here they were bragging about how it didn't even have a chart table on the [rather spacious] bridge. Complete insanity if you ask me, if for no other reason than for planning your next move there's nothing better than a full-sized paper chart to pour over versus the tiny this-instant portal of a 15" laptop display.
aka paper fails safe (albeit soggy), while electronics fail dangerously. And things with dongles fail dangerously^2, as the software's natural state, by design, is to not function.
2c,
Hamish

argh pressed the wrong button...
...or just helping to understand what the BSB headers look like, as far as I've been able to reverse engineer from the NOAA charts**, here's my little GIS -> KAP template tool for GRASS GIS. It just spits out a GeoTiff and a text file with the metadata in it, it is up to you to do the final tiff2bsb step yourself.
Provided for educational purposes and in the hope that it is useful, *Do Not Use As a Primary Means of Navigation*, expect it to be buggy, etc.
[**] any help welcome, see also the ticket in the GDAL bug tracker system.

Both the stable version (2.1) and the devellopment version (2.2) have a button shown as a large A that switches on/off all the text data. The text data also depends on the scale you are using so you may have to zoom in/out.
good luck
Peter
