QGIS: Manhaja ta kyauta don tsarin bayanan kasa

GIS ko GIS (don ma'anarta a cikin Ingilishi) haɗakar kayan aiki ne na kayan aiki, software da bayanan ƙasa don kamawa, adanawa, sarrafawa, bincika da kuma gani a cikin dukkan nau'ikan bayanan da aka ambata wanda ke ba da izinin yanayin sararin samaniya zuwa karatunsu ko gudanarwarsu.

GIS kayan aiki ne masu rikitarwa, suna da mahimmin yanki wanda ke ba da damar bayanin da ke ciki ya kasu zuwa tsari, kuma ta wannan hanyar fassarar ta fi sauƙi da sauri. Bugu da kari, GIS suna da sassauci sosai dangane da aikace-aikacen su, suna bawa masu amfani damar kirkirar tambayoyin mu'amala, yin nazarin bayanan sararin samaniya, gyara bayanai, taswira da gabatar da sakamakon duk wadannan ayyukan, ta wannan hanyar aikace-aikacen su ya kasance a cikin zane-zane, tsarawa birni, kimanta tasirin muhalli, ilmin kimiya na kayan tarihi, da binciken kimiyya da yawa.

Akwai GIS da yawa a yau. Al'umma mai 'yanci ta tsunduma sosai cikin ci gaban software don tsarin buɗe ido na tsarin bayanai. Wannan shine inda ɗayan mafi kyawun kayan aikin kayan aikin kyauta ya shigo: QGIS.

QGIS (a baya jimla GIS) software ce GIS na lambar kyauta, ƙarƙashin lasisi Farashin GPL, aka inganta ta Bude Tushen Gidauniyar Gidaje (OSGeo) en C ++, wanda ke ba da damar gani, gyara da nazarin bayanan ƙasa.

Kamar sauran GIS ɗin da ke ciki, QGIS tana ba da izinin ƙirƙirar taswira tare da layuka masu yawa waɗanda za a iya haɗuwa a ƙarƙashin tsari daban-daban, gwargwadon aikace-aikacen. Amma ainihin abubuwan da ke sanya QGIS kayan aiki mai ƙarfi sune:

• Taimako don SpatiaLite, sararin sararin samaniya da Gara sararin PostGIS, wanda ke ƙara tallafi ga abubuwa na ƙasa a cikin rumbun adana bayanai, yana mai da shi cikin cibiyar adana bayanai.
• Yana ba da izinin ƙirƙirar taswira ta hanyar yadudduka (ƙwayoyin cuta) ko layin vector (layi da polygons), yana tallafawa fannoni da yawa, Shapefile, ArcInfo, MapInfo, GRASS GIS, GeoTIFF, TIFF, JPG, da sauransu.
