Hello We have a simple issue down here: we want to compute the area of an arbitrary polygonal feature.
The straightforward way I thought about was to simply convert that geometry to an equal-area projection, and then let JTS Geometry.getArea do the rest. However... I was surprised that I couldn't find a single equal-area projection in GeoTools that is available globally (say the user wants to compute the area of Russia, or of Antarctica). From what I saw, something like the Mollweide or Sinusoidal projections would do the job, but they don't seem to be currently implemented in GeoTools. Going around the documentation, e-mail lists, etc. my impression is that the only available equal-area projection is the Albers Conic Equal-Area. However, it's not clear to me how I should play around with the standard parallel parameters (ok, would need to study it a little), but more than the that I'm really not sure how this would behave for features that cross the equator. Any help appreciated!
