I-QGIS: Isoftware yasimahla yeenkqubo zolwazi lwejografi

I-GIS okanye i-GIS (kwisifinyezo sayo esiXhoseni) kukudityaniswa okulungelelanisiweyo kwezixhobo zekhompyuter, isoftware kunye nejografi yolwazi ukuze ifake, igcine, ilawule, ihlalutye kwaye ibone ngamehlo kuzo zonke iifom zayo ulwazi olukhankanyiweyo lwendawo oluvumela ukubonakaliswa kwendawo kwindawo yabo ukufunda okanye ulawulo.

I-GIS zizixhobo ezintsonkothileyo, zinendawo yogcino lwedatha evumela ukuba ulwazi oluqulethweyo lwahlulwe lube ngamacandelo, oko ke kwenza ukuba ukutolika kube lula kwaye kukhawuleze. Ukongeza, i-GIS ibhetyebhetye kakhulu ngokuxhomekeke kwisicelo sayo, ivumela abasebenzisi ukuba benze imibuzo enonxibelelwano, bahlalutye ulwazi lomhlaba, bahlele idatha, iimephu kwaye babonise iziphumo zayo yonke le misebenzi, ngale ndlela isicelo sabo sikhona kwimizobo, ukucwangciswa kwedolophu, okusingqongileyo uvavanyo lwempembelelo, i-archeology, kunye nophando oluninzi lwesayensi.

Zininzi ii-GIS ezikhoyo namhlanje. Uluntu olukhululekileyo luye lwabandakanyeka kakhulu kuphuhliso lwesoftware yemithombo yolwazi evulekileyo yemithombo yeendawo. Kulapho esinye sezona zixhobo zinamandla simahla zesoftware singena: QGIS.

QGIS (ngaphambili I-GUM ye-QuantumIsoftware I-GIS ye ikhowudi yasimahla, phantsi kwelayisensi I-GNU-GPL, ephuhliswe ngu Umthombo ovulekileyo weSiseko seGeospatial (OSGeo) en C ++, evumela ukubonwa, ukuhlela nokuhlalutya idatha yendawo.

Njengayo enye i-GIS esele ikho, i-QGIS ivumela ukwenziwa kweemephu ngeendlela ezininzi ezinokudityaniswa phantsi kweefomathi ezahlukeneyo, kuxhomekeke kwisicelo. Kodwa ezona mpawu zenza i-QGIS sisixhobo esinamandla zezi:

• Inkxaso ye-SpatiaLite, i-ORACLE Spatial kunye ne-PostGIS yolwandiso lwendawo, olongeza inkxaso yezinto zejografi kwindawo yogcino lwedatha, ukuyiguqula ibe yindawo yogcino lwedatha.
• Ivumela ukwenziwa kweemephu ngokusebenzisa iirasethi zeraster (iiseli) okanye iileyile zevector (imigca kunye neepoligoni), exhasa iifomathi ezininzi, iShapefile, iArcInfo, iMapInfo, iGREASS GIS, iGeoTIFF, iTIFF, iJPG, njl.
• Ingasebenza phantsi kwayo nayiphi na inkqubo yokusebenza, i-GNU / Linux, BSD, Unix, Mac OSX kunye neWindows

Enye yezona zinto zimangalisayo zeQGIS kukwazi kwayo ukuziqhelanisa nomsebenzisi. Ngolwakhiwo lweplagi eyandisiweyo kunye neelayibrari ezinazo, kunokwenzeka ukwenza iiplagi ezijolise kwimfuno yeprojekthi nganye, ukuvumela ukuba wenze izendlalelo ezinolwazi olunomdla kwimephu nganye. Kuyenzeka ukuba wenze izicelo ezintsha phantsi kweC ++ kunye nekhowudi yePython.

I-QGIS inenguqulo ephathwayo eyenzelwe inkqubo yokusebenza ye-Android, uguqulelo olulungiselelwe ukufakwa kwezixhobo. Ikwavumela ukuba kusetyenziswe iGeolocation yesixhobo esiphathwayo ukusebenzisa i-GIS kwindawo yangoku yomsebenzisi.
