I-GUM ye-Quantum, okokuqala ngqondweni

Qgis Ukuba ngabahlobo be-gvSIG bagcina isithembiso sabo, Ngomvulo olandelayo kaJulayi 27 siza kuba nohlobo 1.9 oluzinzileyo. Ukuza kuthi ga ngoku uvavanyo lube lukhulu, ngokomthamo obonwe kwifayile ye- uluhlu lokuhambisa. Ngelixa uMvulo ufika, kuba xa ndinethemba lokonwaba lokuvuyisana nelizwi lokuthotyelwa, ngendleko yokungalali ngokuqinisekileyo ekufuneka kuphuhliswe ngabaphuhlisi, masiqwalasele i-Quantum GIS enje ngoluhlobo lwentaka.

I-QGIS yaphuhliswa kwi-C ++ isebenzisa izixhobo zeQt, isebenza kwiWindows, Mac nakwiLinux. Iprojekthi yavela ngoMeyi 2002, ngenkxaso yeelwimi ezingama-26 kunye nelayisensi yayo yiGPL.

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

Ukubonakala kweGumum GIS

I-iconografi kunye noyilo lojongano yeyona nto inokuhlawulelwa, ayichaphazeli ukusetyenziswa, kodwa ichaphazela ukungcamla okuhlangeneyo (ukuthengisa) xa usinikela. Inkangeleko yokuba 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 ifuna ingca kwizinto ezininzi ezenziwayo ezi zixhobo zisungulwe kakuhle, zilunge kakhulu ukuba zingaphindi. Xa uqala i-QGIS kwaye ungayifumani ifakiwe, iphakamisa isilumkiso; Kule meko ndenza uphononongo ngaphandle kokufaka ingca. Xa ndifuna ukufaka idathasethi yeGrass, kuba ayifakwanga, isicelo sivaliwe, ke andikukhuthazi ukuyisebenzisa ngaphandle kokufaka zombini izixhobo.

Qgis Iifutshane, Imiyalelo emininzi ineleta eyabelweyo, enjengokuba umsebenzi unokulayishwa ngokucinezela le leta. Oku kuyasebenza kakhulu, ndiyakhumbula ukuba kwi-AutoCAD yenye yezona ndlela zibalaseleyo xa phantse yonke imiyalelo yenziwa ngekhibhodi.

Uhlolo-mpendulo, Kwiphaneli yasekhohlo yimephu ebonisa indawo yokuhambisa, ungqamaniso kuzo zombini iingoma. Iluncedo kakhulu, ungakhetha ukuba zeziphi izaleko ofuna ukuzibona kwisishwankathelo, kwaye inokuphoswa njengefestile edadayo kubungakanani obahlukileyo.

QgisIsakhelo esecaleni, sikhulu nje, ungatsala iiplagi njengeeleyibheli ngaphambili, zinokwenziwa zidade, kwaye ngeqhosha lasekunene elilula lisebenzise okanye usebenze. Kananjalo ulawulo lobubanzi lulula ukurhuqa kungekuphela kwiphaneli yasekhohlo kodwa nakwelingezantsi.

Ipaneli ephantsi, xa kuboniswa itafile yophawu, iyavela kwindawo, kodwa inokudada kwakhona. Isebenza kakhulu, kunye nokukhetha ukusondeza kwimiqolo ekhethiweyo kunye nokutshintsha ububanzi beekholamu ngokutsala okulula kwemouse. Kwisakhelo esezantsi inokukhangela kunye nokukhetha imisebenzi, ngokufanayo nendlela ene-GIS enayo, ngaphandle kwebar yomgangatho olula.

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 ezingaphezuluNjengaso nasiphi na isicelo se-gpl, inzuzo yayo ikwiiplagi ezenziwa luluntu kancinci kancinci (nangona zinenzuzo yokungabikho kwiJava), ngokungagqibekanga kuzisa iziseko kwaye zibonakala zimbalwa kodwa azikho lula njengoko zibonakala ngathi: zinokulayishwa Imigca ye-WFS, ukuthunyelwa kwelinye ilizwe kwiMapServer, ukufaka ulungelelwaniso, ukongeza izixhobo ezibonakalayo ezinjengasentla, isikali kunye nelungelo lokushicilela, isicatshulwa esikweyiphi ikoma, ine-dxf kwi-shp converter, iplagi ukuya kwimifanekiso ye-georeference, i-gps console, i-python console, i-mesh yokulungelelanisa njl. Kodwa eyona nto intle lukhetho lokulayisha iiplagi zeGrass eziyisihloko esahlukileyo. Kuyafana nokwenzekayo nge-gvSIG kunye ne-Sextante nangona ukukhula kweGrass kuhlonitshwa, sesinye sezixhobo ezindala ze-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 ebalulekileyoNjengezinye izixhobo, unokwenza iibhukhimakhi zomhlaba, amaqela oomaleko, iileya zinobuncinci kunye nolawulo oluphezulu lokusondeza, ukufumaneka lula kokongeza iinkqubo zokulungelelanisa kunye noqikelelo; kwimeko yee-shp layers, ukuba zine-prj, i-Qgis ihlangula olu lwazi. Iinkqubo ezininzi zibandakanya ibha yenkqubela phambili, esicinga ukuba intle kakhulu.

Qgis Kuyathakazelisa kakhulu ukuba iimpawu zezinto ziqwalaselwe njani, kuba kwiphaneli enye kukho iithebhu zepropathi ngokubanzi, uphawu, imethadatha, iilebheli, iintshukumo kunye neempawu zetheyibhile; Yonke into ingagcinwa njengesitayile se-.qml kwaye ilayishwe ukufaka kwezinye iindlela Le tafile iyadada kwaye ububanzi nobude bayo bunokuhlengahlengiswa ukunambitha. Nokuba lepaneli kunye nezinye zinokuvulwa 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

Ungayilayisha idatha ye vector shp, gml, Mapinfo kunye ddf, nangona idatha evela kwezinye iifom inokuguqulwa ngesiguquli se-OGR. Ukongeza ii-vector layers ngeWFS kunye nePostGIS. Ukuhlawulelwa kwakhona, kukuvumela ukuba uchaze ubhalo lwekhowudi xa ulayisha umaleko.

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

Ukwenza ii-vector layers ezintsha zinokwenziwa ngeefayile zobume be-OGR okanye ingca. Iiprojekthi zigcinwa njengeXML ngolwandiso lwe-qgs, apho kugcinwa isitayile se-gvSIG.

Ngokumalunga nokuhlelwa kwedatha, iinkcukacha ezinje ngenkqubo yokulungelelanisa, iiyunithi, ukuchaneka kwedesimali, ukuvumela ukuhlelwa kwendalo, imvume okanye umda wokugqagqana kweepoligoni kumaleko afanayo kunye neemeko ze-snap (uhlobo kunye) zigcinwa kwipropathi yeprojekthi. unyamezelo) kulwahlulo ngalunye olufumanekayo kwiprojekthi. Le yokugqibela inomdla, nangona bendiphoxekile kuba inecandelo kunye nenketho ye-vertex kuphela. Ndinyanzelisa ukuba, ingca kufuneka ibe sisizathu soku.

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). Ndizakuyibona emva kokuba ndilayishe izixhobo zokuhlela ingca. Kwaye akubonakali ngathi kukho umkhondo ukuba uninzi luhlela umaleko ngaxeshanye, nabani na ogcina impumelelo kuqala. ugh!

Imveliso yolwazi

Ngeenjongo zokukhupha ngokukhawuleza, kukho ukhetho lokugcina umbono njengomfanekiso, kunye ne-plugin yokuprinta ngokukhawuleza, kodwa ngokungafaniyo ne-gvSIG, ayinalo ulawulo lobeko lwe-ArcView; kodwa endaweni yoko umqambi wokuprinta okhangeleka ngathi uthathiwe ezinweleni, nangona ivumela ukulayisha iifom zedatha, iilebheli, iibhokisi kunye neesimboli, kunye nokuqanjwa okuninzi kunokwenziwa kwiprojekthi, andifumananga ukuba ndingazigcina njani njengeetemplate; incwadana ithi inokwenzeka. Ndicinga ukuba kukho izinto ezingcono kwiiplagi zeGrass kwezi njongo.

I-Quantum gis neAcGGIS

Kakade siya kuthi, emva komhla olandelayo.
