[OpenLayers-Users] How to validate OpenLayers area calculation using PostGIS?

[Phil Scadden]

That doesnt look like a very accurate measurement from PostGIS. What 
happens if you try?
SELECT ST_Area(the_geog,true) As sqm_spheroid
         FROM (SELECT
         geography(
             ST_GeomFromText(    'POLYGON((50 0,-60 -5, -30 -30,50 0))',
         )
     ) As x(the_geog);

This should be comparable with getgeodesicArea in OL.
