Hi All I have a requirement to add tracks to GPS data on a map I'm guessing/assuming that the tracks node will give these functionality [image] Only problem is, I'm not sure how to use it Is it stand alone? does it feed into the Worldmap node? what data do I feed it? I already have data fed …

I actually ran into the same problem last night, and looking through the closed issues on github as well as the source code for it gave me the answer. For the tracks node to work with markers, you have to feed the marker object with location into both the tracks node and the worldmap directly, and h…

One thing I seem to be seeing. I have points in track = 20 When I get multiple tracks on the map, and looking like 20 points, the tracks are all removed and the tracks start again, so rather than losing the oldest track, we lose all track history at given points in time. I would have thought keep…

Missing traces look like it could be a duplicate of points issue. My devices aren't moving, and the red and blue are indoors on a window ledge, so the traces are just from the 'inaccuracy' of the satellite data. So not inconceivable that points get duplicated, within a short space of time

If you are able, can you raise an issue against that node on github please. Preferably with details how to recreate the issue. Thanks.

@ChrisO - If you can find the file node_modules/node-red-contrib-web-worldmap/worldmap/worldmap.js - change line 1014 to if (markers[data.name].lay !== lay) { Stop and restart Node-RED and reload the map page a couple of times to flush the cache. Hopefully that is better.

@dceejay Done I'll keep you posted You still need me raise the issue on github?

Depends if it fixes it or not ....

@dceejay Missing traces seems to be covered [image] easier to see on red Trace At least one duplicate point on green trace too then the green trace does this [image] . 18 points, if I've counted correctly - that 'floating' wasn't the start point, but the penultimate point. And then all poin…

so yes - you may need to raise an issue - if it is possible to share some of the data you are using to re-create that would be helpful

Here's a link to a project I posted on Discourse to track a mobile phone (when I went cycling). http://resources-area.co.uk/node-red-flows/tracking_a_mobile_device.pdf By-the-way, the location shown on your map is just down the road from my daughter's house in Basingstoke on the new Belway estate!…
