JGM,
I've started to work on polygon support in Exhibit using some sample
data provided by Franco Tamoni. I got this much so far:
http://people.csail.mit.edu/dfhuynh/misc/polygons/polygons.html
Most polygons are very tiny and hard to find, except the one in Ghana.
By the way, if you can, give me the polygons of the countries. Right now
I encode a polygon as a list of lat/lng pairs separated by |, e.g.,
{
"birthPlace" : "Crowborough, England",
"label" : "Anthropologist_7",
"ethnicGroup" : "Group_7",
"type" : "Item",
"nationality" : "uk",
"fieldworkPolygon" :
"-19.088076,-63.978882|-19.337062,-64.080505|-19.575318,-64.000854|-19.456234,-63.814087|-19.235957,-63.693237|-19.088076,-63.978882",
"birth" : "1966"
},
