Inspired by the Gmaps Pedometer, Jef Poskanzer has made created the Areometer Google Maps tool that computes the area enclosed by a given path. His tool uses completely accurate spherical geometry, including drawing great circle arcs instead of straight lines. There are a couple other features of interest to Google Maps authors: it remembers the most recent position/zoom/map-type in a cookie; and it correctly handles lines & regions that cross the International Dateline. Try it out..
..Some of Jef's previously featured mashups here on GMM were: Transpac Yacht Race , BART transit map , Paris Metro Map .. Some great work!
