One suggestion: It will be a great to have an option for projection of polar zones on the map.

What do you think?

I tried reproducing the bug, and it doesn’t happen for me. I’ll try following up by email.

I found a minor problem by enter my location JO41js and a distance of 3000, paper size A4. There comes a nice map of europe – but there is no England, no Ireland and no Islands at all. I can see the names of the british cities but no country border. The bug is witth distances between 2000 and 3000. at 1500 or less and 3500 or more it works fine so donot worry.

Unfortunately, my program uses a heuristic to determine what the inside of the curve is, and in some cases, it doesn’t get the right answer. I’ve had some ideas on how to improve it, but I’ve had no time to implement them.

I get around a thousand WordPress comment spams per week even with the reCATCHA plugin, and it takes a while to filter through them and find actual comments.

I would be happy to see your WSPR-net maps, and I could post them here. I’ve thought about adding a feature to allow people to upload a KML file that would add items to an azimuthal map.

There are tools that can convert PDF to a bitmap graphic format.

Thanks,

I am very impressed with the quality of your maps!

For a demo of WSPR at my work, I have just created a MatLab program to get WSPR spots of our 100mW beacon out of the WSPR-net database and plot them on an NS6T azimuthal map. On the firsts few tests the beacon has already been heard in the USA (7000 km) ! I’m sorry that I cannot post any pictures here. Can I mail them to you?

When we get more distant spots, I switch to a map with greater maximum distance. For that purpose I downloaded and save a couple of maps with different distances first. Seeing the spots on an azimuthal map is great, much beather than the Carthesian map on WSPRnet!
As soon as the software is stable (almost, doing some cosmetic things today) I will share it on MatLabCentral as open source and send you a link and some examples too.

As we have a demo to give, I focused on a solution for our location only, so another user will need to download his own maps first. If I have some time later, I will try if I can get that done automatically for any user QTH. I cannot read PDF maps with MatLab, JPG, EMF and the like are not a problem. so have to find out how to solve that problem.

When this works in MatLab, maybe I can someone else can translate the idea in a more common language or make a webpage for it… Later :-)

Kindest regards, 73,
Ben

I want to report a bug.
(For the rest your maps are fabulous, you really have made something unique and of very high quality!!!)

If I create an azimuthal map of Europe (center JO33he, distance 2000 km), the program makes a mistake in land and water. the continent shows up blue, the Atlantic Ocean as white, and England (which is an island) is also white.
This problem is not present in maps with the same center and a radius of either 1000 or 300 km.
