Hi everyone,

I have a database containing a number of polygons in lat/lon coordinates
for which I would like to determine the area in metres. Unforunately the
area() function only calculates area in the given coordinate system. How
can I reproject the data to get the answer in metres? Is it possible to
do this using the length_spheroid() / transform() functions?


Many thanks,

Mark.
