I see a map for a place, but how do I get the coordinates?
Coordinate information is stored in Pleiades "location" resources, which are grouped inside the "place" resources, so you need to drill down.
Pleiades "place resources", e.g. http://pleiades.stoa.org/places/108882, are essentially containers for information about notional places. The
maps on each place are pulling their coordinates from any "location
resources" that have been assigned to that place. You'll see links to
these under "In This Context" --> "Locations". If you click on a
location there, you'll see information about coordinates. This lets us
work with places whose locations are contested or unknown.
These same coordinates are encoded in the alternate KML representations for each place so that you can visualize Pleiades content in Google Earth and other software that can read KML files. Look down the place resource page for a link labeled "KML". The coordinates are also encoded in the alternate JSON representation for each place. The map for the settlement at le Châtelet de Gourzon (introduced above) is, in fact, rendered from the data in http://pleiades.stoa.org/places/108882/json.
You can also download all of our data here:
http://pleiades.stoa.org/downloads. The places tables include "reprLong", "reprLat" and "reprLatLong" columns which hold the coordinates of a single representative point for a place. If you'd just like the agreed upon, single representative latitude and longitude pair for a place, that's the best data source.
You can read more about how we model place information and what "place", "location" and "name" resources mean in the context of Pleiades here: http://pleiades.stoa.org/places.
