24.1. GDAL algoritmus szolgáltató

A QGIS algoritmus szolgáltató különböző elemzési és geofeldolgozási műveleteket valósít meg többnyire kizárólag QGIS API használatával. Így ennek a szolgáltatónak szinte minden algoritmusa „kulcsrakészen” működik minden további konfiguráció nélkül.

Ez a szolgáltató magába foglal pár algoritmust a modulokból és a saját algoritmusait is hozzáadja.
