I-QGIS sisicelo esisimahla nesivulelekileyo se-cross-platform yedesktop yolwazi lwejografi (GIS) exhasa ukujongwa, ukuhlela, ukuprinta, kunye nohlalutyo lwedatha yejografi.

I-QGIS isebenza njengenkqubo yolwazi lwejografi (GIS), ivumela abasebenzisi ukuba bahlalutye kwaye bahlele ulwazi lwesithuba, ukongeza ekuqulunqeni nasekuthumeleni ngaphandle iimephu zegraphic. I-QGIS ixhasa i-raster, i-vector kunye ne-mesh layers. Idatha yeVector igcinwa njengenqaku, umgca, okanye iimpawu zepolygon. Iifomathi ezininzi zemifanekiso ye-raster ziyaxhaswa, kwaye isoftware inemifanekiso ye-georeference.

I-QGIS ixhasa iifayili zemilo, ii-geodatabase zobuqu, i-dxf, i-MapInfo, i-PostGIS, kunye nezinye iifomathi zomgangatho woshishino. Iinkonzo zeWebhu, kuquka iNkonzo yeMephu yeWebhu kunye neNkonzo yeSimo seWebhu, nazo ziyaxhaswa ukuvumela ukusetyenziswa kwedatha evela kwimithombo yangaphandle.

I-QGIS idibanisa nezinye iipakethe ze-GIS ezivulelekileyo, kuquka iPostGIS, iGRSS GIS, kunye neMapServer.[4] Iiplagi ezibhalwe kwiPython okanye iC ++ zandisa izakhono zeQGIS. Iiplagi zingenza i-geocode usebenzisa i-Google Geocoding API, yenze imisebenzi ye-geoprocessing efana naleyo yezixhobo eziqhelekileyo ezifunyenwe kwi-ArcGIS, kunye ne-interface kunye ne-PostgreSQL/PostGIS, i-SpatiaLite kunye ne-MySQL yolwazi.

I-QGIS ingasetyenziswa ne-SAGA GIS kunye neKosmo.
