These new links should have been added here a long time ago. There are also two other related articles that should go as well. Thanks for the reminder. I will address this today.

I have added this to the list. We also have on the horizon several notes and videos on the ENC display of OpenCPN.

You will notice that I changed the name of the article and added a note in the introduction about a new easy method to follow. The features of this plugin are remarkable; every mariner doing weather analysis should have this. I will look into the history of the plugin. The one online is dated about 4 months ago, but that is likely an update to an earlier version. And again, thanks very much for your comment here, and frankly for your politeness in the way you put it! I should have known about this. We learn more everyday about how much opencpn has evolved over the years since we had first looked at it.

We consider this an important operation; this function alone would justify installing opencpn.

The above article and the one linked in it about the header file creation is just to show how the these headers are made. Our goal is to actually make and publish a set of headers, one for each of the standard NOAA weather maps. Once that is done, then the process of making a chart from a map will always be the same, and it will be accomplished from one command using imgkap... with or without a neat java interface. You never have to look at the map at all, and never have to worry about these header files.

Thanks for the information. I am sure many of our readers are glad to see another fine program for the Mac.<br /><br />It does not, however, look like it will do the job we are after. We need to get the weather maps into an echart program that will read both regular noaa charts as well as overlay grib formatted model forecasts. It does not look like that product will do either, but it will clearly georeference a weather map if that is all that is needed. It does say that it will load pdfs, which makes it very interesting because NOAA has their charts in pdf format, and this could be the perfect tool for that application. I will have to see if i can get a copy of that to test that point. thanks again.<br /><br />There are indeed several programs that will do a nice job of georeferencing a weather map. The program called Memory-Map Navigator (memory-map.com), which is an excellent echart program, will georeference any maps including weather maps, but it is $100 and it does not support grib overlays. It looks like the one you reference is about $60, which could make it an interesting option for navigation if it will read noaa chart pdfs…. then it just has to add tides and currents and grib files and it could be a contender for marine applications.<br /><br />But with that said… i agree completely with your description of the process! and we would also like to see some plugin to OpenCPN.<br /><br />We are however getting this a bit better dialed in. See our latest note at http://davidburchnavigation.blogspot.com/2016/01/converting-images-to-bsb-echarts-with.html which off hand looks *more* complex, but in fact is very fast and easy to do once the 3 utility programs are in one folder. <br /><br />Note that if the investment is not a prohibiting factor, then a clear choice for this solution is Expedition from expeditionmarine.com This program will import and georeference a weather map in well less than a minute, and then you have it to use for any navigation application within a world class echart program. <br /><br />Very shortly I will post a note with video on the importance of this process (i.e. importing weather maps to echart programs) and give examples of their use. <br /><br />We are also looking into building a java app that lets you just browse for a standard NOAA weather map on your computer and in one step export it as a BSB chart. if there are programmers reading this who might be interested we are glad to pass on the idea and details for someone else to do it.<br />David Burchhttps://www.blogger.com/profile/13413234790483329339noreply@blogger.comtag:blogger.com,1999:blog-714718709601620866.post-91509175359362221862016-02-01T17:27:06.401-08:002016-02-01T17:27:06.401-08:00This is ridiculous pain in the ass.
