[postgis-users] Polygon area in meters

[Kemal Bayram]

Hi,
 
I'm current working with data in long/lat (wgs84) format and using
st_distance_spheroid to calculate the length of my linestrings in meters.  I
now need to calculate the area of my polygons and am wondering what the
easiest way of doing this would be? 
 
I am thinking projecting the polygon with an equal area projection and then
using st_area on the result.  Anyone have any ideas on suitable
projections/SRIDS?
 
Regards
 
Kemal
