12/8/2023 0 Comments Noaa rnc chart viewer![]() Two popular ones, Fugawi and Polar View, ended support in 2019. In the original 2013 version of this article we had a list of over 20 products, and for now I will just leave these links here at the end, many of which are defunct. These are called S-63 format ENC, whereas we are restricting to S-57 ENC. (4) We are not requiring live GPS functionality, just chart viewing, and we are not requiring coverage of encrypted ENCs or RNCs sold by other nations. These are essentially the same viewers we see at their chart selection options (see /getcharts). Click the (i) icon on the ENC viewer to get into a cursor pick mode. Thus we do not count several online viewers, notably the NOAA viewer for ENC and their NOAA viewer for RNC. (3) Must be stand alone product for PC or Mac or mobile device. Prices range from $50 to $2,000 or so, with several popular products in the $300 to $500 range (Coastal Explorer, Time Zero, WinGPS, to mention just a couple we are familiar with.) Most all of the commercial products include some free demo period that serves to show the unique features they offer, and indeed it is worth checking out a few contenders. (2) Must be truly free, not just a temporary demo. A popular example of these would be the many Navionics products. These can be quite good and the products cost effective, but they are not included here. A large number of these commercial ECS use third party vector charts that they produce themselves based on the official charts. ![]() (1) Must show either or both official RNC and official ENC. To clarify our shortlist amongst these hundreds, we have these criteria: Together this is called an electronic navigation system (ECS). To contact me click HERE.There are hundreds of computer and tablet programs that display echarts in some form and also accept a GPS signal for moving map navigation.

I used Photoshop and combined the images by setting the layer property to "Darken".The sketches of the shoreline and the shipping lanes etc were not the same on my two maps but when I lined up the mark, everything was very close. Once the maps are the same scale, I lined them up by aligning something that has a precise position on both maps, like a buoy.For example, with a map that lists the scale as 1:40,000 and another with 1:20,000, if you resize the larger one to 50% it will line up with the other one when you go to stitch them together. If you resize them to the same scale, they fit perfectly. Note: If you are pasting together two or more charts to make a chart that covers the area where you sail, make note of the map scale.Open Image in Paint, Photoshop, or any other image program.Select the source and destination directories and PNG as the format. ![]() Later the program was listed in "All Programs". I had to open windows exployer and navigate to "c:/Program Files/ BSB Reader" and click on BSBReader. It is nice to have the detail maps separate as that way you can put them some other place if you want. The other maps are the little inserts that go into the blank spaces on the main map. You might want to type "dir" to make sure of the file name. Run bsb2png.exe from this directory by typing (in my csae) "/libbsb/lib2png.exe 18649_1.KAP 18649.png" again change 18649 to the number you remember.I typed "F:" then "CD /charts/bsb_root/18649" Use the number you remembered from before in place of 18649. Navigate to the directory that has the image you want.Click "Start", "Run", and type "cmd" then hit enter. Download it from Sourceforge by clicking this Download Install it. BSBREADER - A newer easier to use program is called bsbreader.Download it from Sourceforge by clicking on Download. BSB2PNG - The program that converts the files is called libbsb.Visis NOAA pages for RNC or ENC and follow the instructions. Or, you can download regions, states, or districts to get a large group of charts. That should save a zip file on your computer.On the bottom of the user agreement, click on "OK" (read it first).On the right side of the page, click on "Download RNC's Go to the Interactive Catalog and select the region you want.Go to the NOAA online ENC chart viewer (.The RNC versions which are the same as the paper charts we are all familiar with and the ones we want. NOAA charts are available for free in two formats: Raster Navigational Charts (RNC) and Electronic Navigational Charts (ENC). Wouldn't it be great if you could print your own NOAA navigational charts, just the size you want, up to date, and do it for free with free software? I did it and here is how I did it.
