Google Planimeter

Measure areas using Google Maps!

Notes:

• The page remembers your most recent position/zoom/map-type for the next time you visit.
• If you haven't visited before, it tries to figure out your location based on your internet address.
• The area computation is done using spherical geometry, so it's correct for large regions.
• The lines between points are drawn as great circles, to go along with the spherical area math.
• Lines that cross the International Dateline do work, with a small gap in the line. (Google Maps applications tend to have problems with the Dateline.)
• Areas that span more than half the globe may display strangely.
• This used to be called the Google Areometer, because I couldn't remember the name of the doohickey used to measure areas on a map. But the Lazyweb reminded be, so I changed it. Links using the old name will continue to work.
