Re: Georeferenced sensor and coverage data

Hello Alejandro, Peter,

I am not clear on this yet. If we can relate a thing like a coverage or a
sensor observation to a geometry (e.g. a point, a bounding box or a
polygon), isn't the thing georeferenced? In my mind, the linkability
requirement covers georeferencing in general.

Regards,
Frans
