I-GUM ye-Quantum, okokuqala ngqondweni

Qgis Ukuba ngabahlobo be-gvSIG bagcina isithembiso sabo, ngoMvulo olandelayo 27 kaJulayi siza kuba ne-1.9 ifom. Ngoku ngoku uvavanyo luye lwaba lukhulu, ngokwemiqulu ebonakalayo uluhlu lokuhambisa. Xa ifika ngoMvulo, xa ndiyathemba ukuba ulwaneliseko ndithi huntshu ukuzaliseka ilizwi lakhe, nangeendleko ndingalali inshorensi ebusuku ukuba babe ngabaphuhlisi yenziwe, makhe sijonge kwi Quantum GIS kunye ibhabha nentaka cowbird.

I-QGIS yaphuhliswa kwi-C ++ usebenzisa i-Qt toolkit, isebenza kwi-Windows, Mac kunye ne-Linux. Le projekthi ivela ngoMeyi ukusuka kwi-2002, ngenkxaso yeelwimi ze-26 kunye nelayisenisi yayo yi-GPL.

Siza kuzama i-1.02 ingqungquthela eyangishiyile ngokwenene ukuba ibe yithuluzi samahhala, ingalayishwa kweli qhagamshelo kwaye ngulo iphepha elisemthethweni laseQgis.

Ukubonakala kweGumum GIS

I-iconography kunye noyilo lwenkcazo yinto ehlawulelwayo kakhulu, ayichaphazeli ukukwazi ukuyenza, kodwa inomdla wokubambisana (ithengisa) xa kufike ukuyihambisa. Uhlobo olo Ndigxeka ngaphambili ye-gvSIG, kuba ngezinye iinkalo ukubonakala kwayo nokungafani kwendalo kubangela ukuba umphathi andixelele "ibukeka njengeprogram yezilwanyana, ezinye iimpawu zibonakala zenziwe nge Paintbrush ye-bits 8".

Qgis

Kodwa kule nto ubukhulu, QGIS ukwenza kakuhle kakhulu, nkqu elula cofa uyakwazi ukukhetha imixholo eyahlukileyo iconography 3 baba nengcinga kakuhle ngokuhambisa i mouse ngapha umba ubonisa indlela kujongano ngabe unjani.

Impawu ezinomdla kwi-Quantum GIS

I-QGIS idinga iGrass kwizinto ezininzi zokusebenza ezi zixhobo ezidibeneyo, ezilungileyo kakhulu ukwenzela ukuba zingaphenduli imizamo. Xa uqala iQGIS kwaye awukwazi ukuyifumana, faka isilumkiso; Kule meko ndiqhuba ukuhlaziywa ngaphandle kokufaka iGrass. Xa ufuna ukulayisha isethi yeData yedatha, ngenxa yokuba ingafaki isicelo sivaliwe, ngoko andincomo ukuyisebenzisa ngaphandle kokufaka zombini izixhobo.

Qgis Iifutshane, Inombolo enemiyalelo enobumba enikwe yona, ukuze ulayishe umsebenzi ngokucinezela le leta. Oku kuyasebenza kakhulu, ndiyakhumbula ukuba kwi-AutoCAD kwakungenye yeendlela ezilungileyo xa phantse yonke imiyalelo yenziwe ngebhodibhodi.

Uhlolo-mpendulo, kwicala lasekhohlo kukho imephu ebonisa indawo yokuthunyelwa, kunye nokuvumelanisa kwiindlela zombini. Uncedo kakhulu, unokukhetha ukuba yeyiphi iindatshana ofuna ukuyijonga kwi-overview, kwaye unako ukuwayeka njengefestile ejikelezayo ngobukhulu obuhlukeneyo.

QgisUluhlu lwesalathisi, lukhulu kakhulu, ungadonsa iifowuni njengeebhalile ngaphambili, zingenziwa zintantyambo, kunye neqhosha lasekunene lisebenzise okanye lisebenzise. Kwakhona ukusingatha ububanzi kukudosa okulula kuphela kwipaneli ekhohlo kodwa kumntu ophantsi.

Ipaneli ephantsi, xa ubonisa itafile yembonakalo, ibonakala kuloo ndawo, kodwa ingaba isantya. Kusebenza kakhulu, kunye neenketho zokuncedisa imigqa ekhethiweyo kwaye utshintshe ububanzi bamakholomu nge-drag drag elula. Kwakhona kwisakhelo esisezantsi sinemisebenzi yokukhangela kwaye ukhetha, kufana nendlela i-GIS eneenkcukacha ezininzi ngayo, ngaphandle kwebha yerhafu elula.

i-quantum gisUkuqulunqwa kwale interface design kwenza kube ezisebenzisekayo ngakumbi, yintoni iframe yeyona ilungileyo, indikhumbuza Microstation, njengokuba kunjalo, athunyelwe ukuba iimpawu window ngaphandle echaphazela eminye imisebenzi.

Uhlalutyo lwedathaIngaba iziseko geoprocessing kunye nophando ukuba umntu angafuna, xa uqala kukho iimpawu ezithile umdla kakhulu ukuba ukhetha ukubona ngesinye isihlandlo, njengoko fTools plugins ziquka terrain modelling, zoxinzelelo lwamanzi kunye nabanye.

Qgis Iiplagizi ezingaphezuluNjengaye nawuphi na isicelo GPL, inzuzo yakho kwi plugins eyenza kancinane kuluntu (nakuba uncedo wokungabi kwi Java), ngokungagqibekanga luzisa ezingundoqo kwaye zibonakala zimbalwa kodwa elula njengoko zibonakala: loadable umaleko WFS, thumela ku MapServer, bamba ukuququzelela, yongeza inkxaso imboniselo njenge ngasentla, isikali copyright, itekisi ikoma-emida, abe dxf Converter SHP plugin for imifanekiso georeferencing, GPS console, python console, zilungelelanise igridi , njl Kodwa ke engcono ukhetho ukulayisha iplagi Grass na umba eyahlukileyo. Kunxibelelana nento eyenzeka kunye gvSIG kunye kwesextant nangona bokudlala ingca na ezifanelekileyo, omnye izixhobo zindala GIS.

Okubangel 'umdla kukuba OGR lokuguqulela, nto leyo ukuguqula iimaleko phakathi iifomati ezahlukeneyo, ezifana SHP, DGN, eyisebenzisayo, GML, CSV, KML, MapInfo kunye nesithuba BD nge ODBC, I SQL yam, PostgreSQL, phakathi kwabanye.

Eyona nto ihamba phambili: dxf ukuya kwi-shp kunye ne-kml ukuya kwi-dxf, eyona siseko kodwa engenziwanga ngezinye iinkqubo zokuhlawula.

Imisebenzi ebalulekileyo, njengamanye amathuluzi, unokwenza iibhukummaki zendawo, amaqela omqolo, izitya zinolawulo oluncinci kunye noluninzi lwezondlo, kulula ukudibanisa iinkqubo kunye neenkqubo zokucwangcisa; xa kwenzeka i-shp layers, ukuba i-prj, i-Qgis ihlangula le ngcaciso. Zininzi iinkqubo ziquka ibha yenkqubela phambili, esicinga ukuba yinto enhle.

Qgis Kuyathakazelisa kakhulu ukuba iimpawu zezinto ziqwalaselwe njani, kuba kwipaneli enye kukho iithebhu zeepropati eziqhelekileyo, isimboli, imethadatha, iilebula, izenzo kunye neempawu eziphathekayo; yonke into ingagcinwa njenge style .qml kwaye ilayishwe ukuyifaka kwezinye iindawo. Kwakhona le tafile iyajikeleza kwaye unokulungelelanisa ububanzi bayo kunye nokuphakama ukunambitha. Kwaye le ganeli kunye nabanye banokuvulwa njengesicelo esahlukileyo.

i-quantum gis Kwakhona kugxininisa ekusebenzeni okubonakala ngathi kulula kodwa kunokuba luncedo kakhulu, njengokulinganisa kwemida eqhubekayo, eboniswa kwipaneli yamathala, equka umgama wecandelo ngalinye.

Ukufikelela kunye nokuhlela idatha

Ungakwazi ukulayisha idatha ye-vector shp, i-gml, i-Mapinfo kunye ne-ddf, nangona unokuguqula idatha kwezinye iifom nge-converter ye-OGR. Ukongeza izalathisi ngeeWFS ne-PostGIS. I-Rescatable, ikuvumela ukuba ucacise umgca wekhowudi xa ulayisha uluhlu.

Ngokubhekiselele kumacandelo e-raster, ixhasa kakhulu, ngaphandle kweWMS. Ukongezelela, kubandakanya ukufunda i-OGC, i-WCS, i-CAT, i-SFS kunye ne-GML imigangatho.

Ukudala izakhi ezintsha zentengiso zingenziwa kwiifayile zefom ye-OGR okanye i-Grass. Iiprojekthi zigcinwa njenge-XML kunye ne-qgs extension, apho ukulungiswa kwamacwecwe kugcinwa kwisitayela se-GVSIG.

Ke wokuhlela data, kule projekthi zobumnini zigcinwa enikiweyo njengoko nokulungelelanisa inkqubo, iiyunithi, ikwazi lokugqibela, bakwazi ukuhlela topological, ukwenza okanye umda eneepoligoni zidlulela kule nwebu efanayo kunye neemeko snap (uhlobo kunye ukunyamezela) kwisiseko ngasinye kwisiprojekthi. Olu lugqithiso lunomdla, nangona ndididekile kukuba inokhetho kunye nenxalenye ye-vertex kuphela. Kwakhona, i-Grass kufuneka ibe yinto yokulungelelanisa oku.

Ndazama ukuhlela ungqimba, ukufaka i-vertex, kodwa ndakuyifumanisa, ngaphandle kokuba kubalulekile ukuba ungeze ukhetho lwe-snapping (Ndiyaxolisa ngenxa yokuxhamla kwam, okokuqala ndidlala le nto yokudlala). Ndiza kuyibona emva kokuba ndilayishe izixhobo zokuhlela zikaGrass. Kwakhona akukho kubonakala ukuba kukho umkhondo xa abaninzi behlela uluhlu olufanayo, ozuza kuqala. !

Imveliso yolwazi

Ngeenjongo zokuphuma ngokukhawuleza, kukho ukhetho lokugcina umbono njengomfanekiso, kunye neplagin yokunyathelisa ngokukhawuleza, kodwa ngokungafani ne-gvSIG, ayinalo ukulawula ulawulo lwe-ArcView style; kodwa umqambi yoshicilelo obonakala isuntswana esithathwe iinwele, kodwa unako ukulayisha dataframes, iilebhile, iibhokisi neempawu, yaye uyakwazi ukwenza Ukuqamba eziliqela yeprojekthi, ndafumanisa uzigcinele neethemplethi; le ncwadana ithi inokwenzeka. Ndicinga ukuba kwiiplagizi zeGrass kukho izinto ezingcono kulezi njongo.

I-Quantum gis neAcGGIS

Kakade siya kuthi, emva komhla olandelayo.
