[Qgis-user] Code of area calculation in qgis (ellipsoid WGS84)

[Gabor Szakacs]

Hi there,
I seek to calculate area (in hectares) in a MultiPolygon layer in crs 4326,
without the need to reproject to projected coordinates.

I was able to get this done using Python, but the calculation takes much
longer than the area calculation in QGIS (elipsoide wGS84), using $area.
Both area calculations are identical until the 6th decimal place of a
hectare (= < 1m2).

To speed up area calculation, I would like to know the code snippet that
QGIS is using to calculate $area.

Any help is very much appreciated!

Thanks,
Gabor
