QGIS yog ib tug dawb thiab qhib-qhov chaw cross-platform desktop geographic ntaub ntawv lawv (GIS) daim ntawv thov uas txhawb saib, editing, printing, thiab tsom xam cov ntaub ntawv geospatial.

QGIS functions li geographic ntaub ntawv lawv (GIS) software, uas cov neeg siv los tsom xam thiab edit spatial ntaub ntawv, ntxiv rau composing thiab exporting graphical maps. QGIS txhawb raster, vector thiab mesh layers. Vector cov ntaub ntawv yog muab cia li taw tes, kab, los yog polygon nta. Ntau hom dluab raster yog txaus siab, thiab cov software yuav georeference dluab.

QGIS txhawb shapefiles, koj tus kheej geodatabases, dxf, MapInfo, PostGIS, thiab lwm yam kev lag luam-txheem formats. Web services, nrog rau Web Map Service thiab Web Feature Service, kuj txaus siab siv cov ntaub ntawv los ntawm lwm qhov chaw.

QGIS integrates nrog lwm qhib-qhov chaw GIS pob khoom, xws li PostGIS, GRASS GIS, thiab MapServer. [4] Plugins sau ntawv hauv Python los yog C ++ cuag QGIS lub peevxwm. Plugins yuav geocode siv cov Google Geocoding API, ua geoprocessing functions zoo ib yam li cov qauv cuab yeej nyob hauv ArcGIS, thiab interface nrog PostgreSQL/PostGIS, SpatiaLite thiab MySQL databases.
