Hi, alternate alg was introduced in the time, when QgsZonalStatistics offered only some basic statistical information, e.g. min/max, count and couple of other values and did not allow to select individual stats.
Now, when QgsZonalStatistics is much more powerful personally I (as author if this alternate alg) see no sense in keeping other duplicated algorithm. 2017-06-28 9:07 GMT+03:00 Nyall Dawson <[email protected]>: > On 28 June 2017 at 15:55, Mathieu Pellerin <[email protected]> wrote: >> > >> Two statistical outputs (variance and mode) aren't available in >> QgsZonalStatistics-based alg, while two outputs (minority and majority) are >> missing from the alternate alg. > > Thanks! > > Mode = majority here, so both algs offer this value. > > Variance is trivial to calculate from the standard deviation, so > that's not a significant loss. > > I guess the other unknowns are speed & robustness of the two > algorithms.
