Increare accuracy of area calculation
|Reported by:||hopfgartner||Owned by:||pramsey|
In the case of polygons which are "far" away from the origin, as happens frequently in projected SRS, the applied change may increase the accuracy of the area calculation by some order of magnitude. Doing some tests on UTM32N geometries and comparing the result with the result calculated with a routine written with http://de.php.net/manual/en/book.bc.php the accuracy improved by 4 to 5 orders of magnitude. The patch is against PostGIS 1.5.2.
