GeoScript adds spatial capabilities to dynamic scripting languages

GeoScript implementations are available in JavaScript, Python, Scala, and Groovy.

js> var geom = require("geoscript/geom");
js> var p = new geom.Point([-111.0, 45.7]);
js> p
<Point [-111, 45.7]>
js> var proj = require("geoscript/proj");
js> var p2 = proj.transform(p, "epsg:4326", "epsg:26912");
js> p2
<Point [499999.42501775385, 5060716.092032814]>
js> var poly = p2.buffer(100);
js> poly.area
