Automating GPS to map

[pransil]

I figure someone has already done this but I could not find it.

I have an RPI/BBNOS system with SignalK and I am automatically writing GPS coords to influx every minute. I would like to automatically send the GPS coordinate once per hour to my map on my WordPress based blog. I can make my map pick up the coords from a file kept on an internet accessible file storage system.

I would like to do some preprocessing to only send coords if the boat is moving and to not send 'glitch' coords (sometimes the GPS coords are wrong by a lot but if I look at 3 consecutive points, I can tell if the middle point was a glitch), and amybe a few other special conditions.

If anyone has done something like this or can point me to something that does some of this, it would be appreciated. Especially if the code is in python. :-)
thanks
Pat

I wrote signalk-to-batch-format for a similar use case. There are more details in the README. https://github.com/c33howard/signalk-to-batch-format It's an unconditional publish though, which I prefer. My day job deals with distributed systems and I've learned to love constant work. Additionally, always publishing gives you a chance to alarm and notice that your last GPS push hasn't been made for some time. It's nice to know that's definitely an error in the system, rather than either an error OR because the boat hasn't moved. I've thought about setting up conditional alarms though, based on how far the boat is from my home slip. I've yet to implement that. If/when I do, it'll likely be a separate plugin that publishes a stat that is distance-from-home or similar. I'd then use that as an AND condition in my alarms. At least that's my current plan.

You could also easily do this in node-red.  I think I have a node that detects movement, I can send it if you wanted to go that route.  Enjoy Brad Harley. — Sent from my iPhoneOn Feb 1, 2024, at 23:24, Craig Howard ***@***.***> wrote: I wrote signalk-to-batch-format for a similar use case.
