A key use case for a geo microformat is for people to be able to refer
to a place from a web page. Currently, people do this predominantly in
* referring to a human-readable address ('San Francisco', '665 3rd
Street, SF, 94107', '3rd and Townsend', 'by the ballpark'
* linking to an existing map service with a proprietary URL (mapquest,
These are useful in human terms, but they don't really map onto a point
location, as they are referring to a human-scale area.
Bare latitude/longitude is insufficient to present a cartographic
representation to a user, as there is no way to know what scale to
display that map at.
What would be useful, in my view, would be to translate the above into
a latitude, longitude, and radius of interest. These can be translated
back into different map display systems.
Translating the human-readable names is a tricky problem, but one that
mapping services already tackle with variable success, so having a way
of presenting the human-readable and lat/long/radius data as
alternatives is valuable.
