Welcome to the GeoDia User Forum

This blog is set up to serve as a way to collect feedback from users of GeoDia, a spatial timeline of the ancient Mediterranean developed by Adam Rabinowitz (University of Texas at Austin, department of Classics), Peter Keane and Stuart Ross (UT Liberal Arts Instructional Technology Services), and Nick Rabinowitz, using Nick's timemap.js library and the LAITS DASe architecture, with support from two LAITS project grants. It will also serve as a place where GeoDia managers can alert users to additions, changes, and new developments. The GeoDia code itself can be found at http://code.google.com/p/geodia/.

GeoDia sites linked to Pleiades URIs

We have now done a preliminary round of linking to Pleiades URIs for the sites in GeoDia. To do this, we queried the Pleiades feed to look for sites with the same name within the geographic bounding-boxes used by Pleiades to locate sites. These bounding-boxes are based on the spatial divisions of the Barrington Atlas.

About 2/3 of our sites could be connected automatically. Some others aren't found in Pleiades, while some didn't  link because the Pleiades feed didn't expose all alternate names.

We will be interested to see how well we can connect sites now that the Pleiades project is drawing more specific locations from Harvard's DARMC project. The DARMC site locations are less specific, in many cases, than the GeoDia locations, which are derived from satellite imagery rather than cartographic coordinates. The question will be whether the Pleiades feed will include both bounding-box information and specific DARMC coordinates.
