Crowdsourcing depth for openseamap

It depends, but the more data you have, the more accurate you can get. The perfect case would be you have a reading from two sensors from the exact same position at the exact same time. Obviously this is not possible. But given enough readings from enough reference points, you can calculate offsets of a sensor. Tides also make this interesting. It's definitely a hard problem, but it's not impossible.

Crowdsourcing depth for openseamap

That's not actually true. Navionics does this with their sonar charts and it's really good. Given shared reference points, you can determine the offset of an individual sensor. You just need enough data

Looks like at least one other person has tried to make a SignalK plugin https://github.com/OpenSeaMap/depth_webfrontend/issues/230

Crowdsourcing depth for openseamap

Oh wow, I had no idea that project exists. My main motivation for getting into SignalK a couple months ago was so I could start tracking my own depths and maybe do something like this eventually.

Yeah, I was thinking about that. I think there should be a sanity test that has the top ~N plugins installed and runs some very basic integration tests.

No, nothing specific. Just working on updating dependencies because the debt starts to stack up

Yeah. I'm going to keep digging for a minute and see if I can fix the node-red issue with body-parser 2, but reverting is probably the easy route for now

Right, but they tried to update to body-parser 2 and their tests were failing, so they reverted it

So node-red is using body-parser 1.20.3 internally, so must be some kind of conflict mixing versions
