World Map Great Circle Lines

[aa0z]

I took a look around the web, but couldn't find a definite answer, so I'm posting here.

I'm looking at producing the following type map with the worldmap node. If it's not a current feature, I'd like to put in a request to make it a feature.

This is for amateur radio contacts mapping from a certain location where you are transmitting from.

As you contact another station, that station is plotted on on the map from an on-line lookup service for lat/lon. A great circle line is drawn from your transmitting location to each pinned station on the map. It would be nice to turn the great circle lines on/off also via the map legend as a layer.

Thanks
Kyle

Interesting thought. Indeed it should be possible to add an option to draw great circle lines. Adding buttons to show hide would be down to you. (probably easiest via embedding it in dashboard).
Will be in version 2.24.0 shortly

var m1 = { payload: { name: "GC1", greatcircle: [[51.464, 0], [25.76, -80.18]] } };
var m2 = { payload: { name: "GC2", greatcircle: [[51.464, 0], [35.6, 139.8]] } };
return [[m1,m2]];

Crikey that's fast work!

[aa0z]

I'm assuming you will still be able to plot a pin at each lat/lon and then draw the great circle from you home base to each pin?

[dceejay]

but of course

[dceejay]

Worldmap 2.24.0 now available

[aa0z]

Works great! Thanks for the quick add to the map! This will be a great addition to the map for my application.

One feature request in the future to make the great circle lines the color of the icons?

Thanks again. Kyle

I suppose the optional color properties may be required as per the readme.

var m1 = { payload: { name: "London", lat: 51.464, lon: 0 } };
var m2 = { payload: { name: "Miami", iconColor:"#ff00ff", lat: 25.65, lon: -80.18 } };
var m3 = { payload: { name: "Tokyo", iconColor:"#00ffff", lat: 35.6, lon: 139.8 } };
var m4 = { payload : { name: "GC1", color:"#ff00ff", greatcircle: [[51.464, 0], [25.76, -80.18]] } };
var m5 = { payload: { name: "GC2", color:"#00ffff", greatcircle: [[51.464, 0], [35.6, 139.8]] } };
return [[m1,m2,m3,m4,m5]];

[aa0z]

Yep. I should of realized. Thanks.

Just had a play with this feature - it's great.
I don't know if this is the right way to do it (without refreshing the map)... if you want to remove a great circle you can set the start and end coordinates to be the same (so it sorts of disappears). To remove the marker then the 'deleted' option can be used.

[dceejay]

The line should also disappear if it is set to deleted. please shout if not.

[dynamicdave]

Just checked and can confirm.. deleted:true will delete the great circle. So that's a neater way of doing it.

[dynamicdave]

This is just a bit of pure fun on New Year's Eve, 2021. You can probably guess what it does - or try it out.
