Dear all,

I am presently working on a project for the Muséum National d'Histoire Naturelle in Paris and we are using CRM. We need to model an observation activity which consists in observing from a certain place some taxon which may be at a distant place. For example, observing from a lighthouse a beluga whale (Delphinapterus leucas) passing at a few miles distance. My first guess was to consider this activity as a kind of measurement and therefore I used E13 Attribute Assignment as a parent class for ObservationActivity. The observation activity P7 took place at the lighthouse and "observed" a location (gps coordinates where the whale was seen).

Do you think this makes sense? Do you see any other way to model this ?

Thank you very much for your help,
All the best to all,
Pierre
