fixes #8866
fixes #8920
fixes #8925
fixes #8954

I'm not sure how to address this suggestion:

From the usage perspective it would be nice to have documented:
how to access a set of sensors and sensor observations related to a selected location or feature-of-interest
how to style a location based on (recently) measured values in the related /sensor/observation

I assume the first one is about #8925 and the second one is layer symbology or something else?

@pvgenuchten could you please help clarify your suggestions? Thanks

Thanks for tagging me Anita,

how to access a set of sensors and sensor observations related to a selected location or feature-of-interest

I think this was intended as: sensors typically register observations on a feature of interest, a water body, a soil horizon, an organism, or similar. The features of interest (which can be visualized as a map layer) could be selected and used as a filter to locate relevant observations for it.

how to style a location based on (recently) measured values in the related /sensor/observation

a topical use case is to take a latest observation of a sensor at a location and use the value to colorise an icon (red for high, green for low; eg noise, air quality, etc). Describe how one could create such a map.
