ʻO QGIS kahi noi manuahi a me ka open-source cross-platform desktop geographic information system (GIS) e kākoʻo ana i ka nānā ʻana, hoʻoponopono, paʻi, a me ka nānā ʻana i ka ʻikepili geospatial.

Hana ʻo QGIS ma ke ʻano he polokalamu ʻōnaehana ʻike honua (GIS), e ʻae i nā mea hoʻohana e kālailai a hoʻoponopono i ka ʻike kikoʻī, ma waho aʻe o ka haku ʻana a me ka lawe ʻana aku i nā palapala kiʻi. Kākoʻo ʻo QGIS i nā papa raster, vector a me nā mesh. Mālama ʻia ka ʻikepili Vector ma ke ʻano he kiko, laina, a i ʻole nā ​​hiʻohiʻona polygon. Kākoʻo ʻia nā ʻano like ʻole o nā kiʻi raster, a hiki i ka polokalamu ke kuhikuhi i nā kiʻi.

Kākoʻo ʻo QGIS i nā shapefiles, nā geodatabases pilikino, dxf, MapInfo, PostGIS, a me nā ʻano hana maʻamau ʻoihana ʻē aʻe. Kākoʻo ʻia nā lawelawe pūnaewele, me ka Service Map Web a me Web Feature Service, e ʻae i ka hoʻohana ʻana i ka ʻikepili mai nā kumu waho.

Hoʻohui pū ʻo QGIS me nā pūʻolo GIS open-source ʻē aʻe, me PostGIS, GRASS GIS, a me MapServer.[4] ʻO nā plugins i kākau ʻia ma Python a i ʻole C++ e hoʻonui i ka mana o QGIS. Hiki i nā plugins ke geocode me ka hoʻohana ʻana i ka Google Geocoding API, e hana i nā hana geoprocessing e like me nā mea hana maʻamau i loaʻa ma ArcGIS, a me ka launa pū me nā ʻikepili PostgreSQL/PostGIS, SpatiaLite a me MySQL.

Hiki ke hoʻohana pū ʻia ʻo QGIS me SAGA GIS a me Kosmo.
