A SF media transcoder is placed in a lamp-post. It has no means to obtain GPS coordinates but has a _loc_label_ provided to it as a VM environment variable. It provides zeros in the longitude and latitude. In subsequent data analysis we can search for this SF by location label.

A SF that is a proxy to a user attached to a NAP running in street lamp post LAMP_1. Here we have knowledge both of the logical location of the service and also the fine-grained, dynamic position of the service user. Lots of interesting possibilities with both of these bits of information!

Note that tags are always strings and cannot be floats, therefore log and lat will always be stored as a measurement field.
