It is a little unclear to me how to get data from a local instance of the frost server running in docker to show up in the Helgoland map (which I also have running in docker). I tried selecting the adjust map button and changing the provider to OGC SensorThings API (STA, 1.0) but the data bought up from that doesn't reflect the data I posted from the frost server (indeed the data is currently pulled from https://calgary-aq-sta.sensorup.com/v1.0/). I also see the following in the center bottom of the adjust map page and not sure if this is the expected behavior:
"https://nexos.demo.52north.org/52n-sos-nexos-test/api/ is currently not reachable
https://sensorweb.demo.52north.org/sensorwebclient-webapp-stable/api/v1/ is currently not reachable
https://sensorweb.demo.52north.org/sensorwebtestbed/api/v1/ is currently not reachable"
