area calculation conversion to meters

[Paul Spencer]

Hi all,

I'm measuring the area and length of features using  
MgGeometricEntity::GetArea() and GetLength() in the Sheboygan data.   
This returns values in the units of the projection, which happens to  
be decimal degrees.  Not so useful.  I'd like the result to be in  
meters.

Since this code needs to be generic, I've implemented some stuff to  
transform the geometry into a coordinate system that supports  
meters.  This is not too accurate since I arbitrarily picked a World  
LCC projection wkt :)

What is the recommended way of doing this calculation?

Cheers

Paul
