QGIS ndi pulogalamu yaulere komanso yotseguka yopezeka pakompyuta yapaintaneti (GIS) yomwe imathandizira kuwonera, kusintha, kusindikiza, ndi kusanthula deta ya geospatial.

QGIS imagwira ntchito ngati pulogalamu ya Geographic Information System (GIS), yomwe imalola ogwiritsa ntchito kusanthula ndikusintha zambiri zapamalo, kuphatikiza kupanga ndi kutumiza mamapu ojambula kunja. QGIS imathandizira zigawo za raster, vector ndi mesh. Deta ya Vector imasungidwa ngati mfundo, mzere, kapena mawonekedwe a polygon. Mawonekedwe angapo azithunzi za raster amathandizidwa, ndipo pulogalamuyo imatha zithunzi za georeference.

QGIS imathandizira mawonekedwe, malo osungira, dxf, MapInfo, PostGIS, ndi mitundu ina yamakampani. Ntchito zapaintaneti, kuphatikiza Web Map Service ndi Web Feature Service, zimathandizidwanso kulola kugwiritsa ntchito data kuchokera kunja.

QGIS imaphatikizana ndi mapaketi ena otsegula a GIS, kuphatikiza PostGIS, GRASS GIS, ndi MapServer.[4] Mapulagini olembedwa mu Python kapena C ++ amakulitsa luso la QGIS. Mapulagini amatha kupanga geocode pogwiritsa ntchito Google Geocoding API, kuchita ntchito za geoprocessing zofanana ndi zida zomwe zimapezeka mu ArcGIS, ndikulumikizana ndi ma database a PostgreSQL/PostGIS, SpatiaLite ndi MySQL.

QGIS itha kugwiritsidwanso ntchito ndi SAGA GIS ndi Kosmo.
