I-QGIS: Isoftware yamahhala yezinhlelo zolwazi lwendawo

I-GIS noma i-GIS (ngesifinyezo sayo esiNgisini) ukuhlanganiswa okuhlelekile kwehadiwe, isoftware nedatha yezwe ukuze kuthathwe, kugcinwe, kulawulwe, kuhlolisiswe futhi kubonwe ngamehlo kuzo zonke izinhlobo zayo imininingwane ebhekiswe endaweni evumela ukuhlukaniswa kwesikhala sendawo endaweni yabo ukufunda noma ukuphathwa.

I-GIS ingamathuluzi ayinkimbinkimbi kakhulu, ine-database yezwe evumela ukuthi ulwazi oluqukethwe luhlukaniswe lube izingqimba, okwenza ukuhumusha kube lula futhi kusheshe. Ngaphezu kwalokho, i-GIS iguquguquka kakhulu ngokuya ngohlelo lwayo lokusebenza, ivumela abasebenzisi ukuthi bakhe imibuzo yokusebenzisana, bahlaziye imininingwane yendawo, bahlele idatha, amabalazwe bese bethula imiphumela yakho konke lokhu kusebenza, ngale ndlela uhlelo lwabo lokusebenza lukhona ebalazweni, ukuhlela amadolobha, ezemvelo ukuhlolwa komthelela, imivubukulo, kanye nophenyo oluningi lwesayensi.

Kunama-GIS amaningi atholakalayo namuhla. Umphakathi wamahhala ubambe iqhaza elikhulu ekwakhiweni kwesoftware yezinhlelo zemininingwane evulekile zemininingwane yezindawo. Yilapho enye yamathuluzi esoftware anamandla kakhulu ingena khona: QGIS.

QGIS (phambilini GIS Quantum) yisoftware I-GIS ye- ikhodi yamahhala, ngaphansi kwelayisense I-GNU-GPL, ithuthukiswe ngu Umthombo ovulekile weGeospatial Foundation (OSGeo) e C ++, evumela ukubonwa, ukuhlela nokuhlaziywa kwedatha yezwe.

Njengezinye i-GIS ezikhona, i-QGIS ivumela ukwenziwa kwamamephu anezendlalelo eziningi ezingahlanganiswa ngaphansi kwamafomethi ahlukile, kuya ngohlelo Kepha izici zangempela ezenza i-QGIS ithuluzi elinamandla yilezi:

• Ukusekelwa kwesandiso sendawo seSpatiaLite, ORACLE Spatial kanye nePostGIS, okunezela ukusekelwa kwezinto zendawo endaweni yokugcina imininingwane, ukuyiguqula ibe yindawo egcina imininingwane yendawo.
• Ivumela ukwenziwa kwamamephu ngezendlalelo ze-raster (amaseli) noma izingqimba ze-vector (imigqa nama-polygoni), esekela amafomethi amaningi, i-Shapefile, i-ArcInfo, i-MapInfo, i-GRASS GIS, i-GeoTIFF, i-TIFF, i-JPG, njll.
• Ingasebenza ngaphansi kwanoma yiluphi uhlelo lokusebenza, i-GNU / Linux, BSD, Unix, Mac OSX neWindows

Enye yezinto ezimangalisa kakhulu zeQGIS yikhono layo lokuzivumelanisa nomsebenzisi. Ngokwakhiwa kwe-plugin enwebekayo nemitapo yolwazi enayo, kungenzeka ukudala ama-plugins agxile esidingweni sephrojekthi ngayinye, ikuvumela ukuthi wakhe izingqimba ezinolwazi oluthakazelisa ngempela emephini ngayinye. Kungenzeka ukudala izinhlelo ezintsha ngaphansi kwe-C ++ nekhodi yePython.

I-QGIS inenguqulo yeselula eyenzelwe uhlelo lokusebenza lwe-Android, inguqulo elungiselelwe okokufaka kokuthinta kwemishini. Ibuye ivumele ukusebenzisa i-Geolocation yedivayisi yeselula ukusebenzisa i-GIS endaweni yamanje yomsebenzisi.
