Quantum GIS, umbono wokuqala

Qgis Uma abangane be-gvSIG bagcina isithembiso sabo, ngoMsombuluko olandelayo 27 kaJulayi sizoba nesimo esiqinile se-1.9. Okwamanje ukuhlolwa kuye kwaba kuhle, ngokusho kwevolumu ebonakalayo uhlu lokusabalalisa. Nakuba ifika ngoMsombuluko, lapho ngithemba ukwaneliseka ekubongeni nokugcwaliseka kwezwi lakhe, bangakunaki becabangela umshwalense nobusuku obungamashumi amane ukuba onjiniyela kwenziwe, ake sibheke Quantum GIS nokubaleka inyoni cowbird.

I-QGIS ithuthukiswe ku-C ++ usebenzisa i-Qt toolkit, igijima ku-Windows, Mac ne-Linux. Le phrojekthi ivela ngoMeyi kusukela ku-2002, ngokusekelwa kwezilimi ze-26 futhi ilayisense yayo yi-GPL.

Sizolinga inguqulo ye-1.02 engishiyile ngokuphelele yanelisithuluzi samahhala, ingalandwa kusuka kulesi sixhumanisi futhi yilokho ikhasi elisemthethweni le-Qgis.

Ukubonakala kwe-Quantum GIS

I-iconography ne-design interface ikhululeka kakhulu, ayithinti ukusebenzisana, kodwa inezinambitheka ezinkampani (ithengisa) uma kuziwa ukuyihlinzeka. Isimo lokho Ngangigxeka ngaphambili ye-gvSIG, ngoba ngesikhathi esifanayo ukubukeka kwayo nokungafani kokudala kwakwenza umphathi angitshele "kubonakala sengathi uhlelo lwezilwane, ezinye izithonjana zibonakala zenziwe nge-Paintbrush ye-bits 8".

Qgis

Kodwa kulokhu ubukhulu, I-QGIS inhle kakhulu, ngisho nokuchofoza okulula ongakhetha phakathi kwezingqikithi ezihlukahlukene ze-3 ze-iconography kahle kahle, ngokudlula igundane phezu kwesihloko kubonisa indlela i-interface ezobukeka ngayo.

Izici ezithakazelisayo ze-Quantum GIS

I-QGIS idinga u-Grass ngezinsiza eziningi ukuthi lelo thuluzi lihlanganisiwe kahle, lihle kakhulu ukuze lingaphindi imizamo. Uma uqala i-QGIS futhi ungayitholi ifakwe, vusa isaziso; Kulokhu ngenza isibuyekezo ngaphandle kokufaka uhlaza. Lapho ufuna ukulayisha isethi yeDatha yeDrass, ngoba ayifakwanga uhlelo lokusebenza ivaliwe, ngakho-ke angincoma ukuyisebenzisa ngaphandle kokufaka amathuluzi womabili.

Qgis Izinqamuleli, Inombolo eningi yemilayezo inencwadi eyabelwe, ukuze ukwazi ukulayisha lo msebenzi ngokucindezela le ncwadi. Lokhu kuyasebenza kakhulu, ngiyakhumbula ukuthi ku-AutoCAD kwakungenye yezinto ezinhle kakhulu lapho cishe wonke umyalo wenziwa ngekhibhodi.

Ukubuka konke, ephaneli lesokunxele kukhona imephu ekhombisa indawo yokuthunyelwa, ngokuvumelanisa kuzo zombili izindlela. Iwusizo kakhulu, ungakhetha ukuthi yiziphi izendlalelo ozifunayo kuhlolojikelele, futhi ungase uzilahle njengefasitela elintantayo ngosayizi ohlukile.

QgisUhlaka lwamahlangothi, lukhulu kakhulu, ungadonsa ama-plugin njengamalebula ngaphambili, angenziwa aguqule, futhi nge inkinobho elula kwesokudla noma kusebenze. Futhi ukusingatha ububanzi kungokuhudula okulula hhayi kuphela kuphaneli lesokunxele kodwa kumuntu ophansi.

Iphaneli eliphansi, uma ubonisa itafula lomqondo, livela endaweni, kodwa futhi lingase lithele. Isebenza kahle kakhulu, ngezinketho zokusondeza imigqa ekhethiwe futhi ushintshe ububanzi bamakholomu ngokudonsa imouse elula. Futhi kuhlaka oluphansi linemisebenzi yokusesha bese ukhetha, kufana nokuthi i-Manifold GIS inayo kanjani, ngaphandle kwesibalo sesimo esilula.

i-quantum gisUkuvumelanisa kwalesi sikhombimsebenzisi esibonakalayo kusenza sisebenziseke kakhulu, amafrimu athambileyo angcono kakhulu, angikhumbuza kakhulu i-Microstation, ngoba ngenxa yalokho, ifasitelana lemfanelo lingaboniswa ngaphandle kokuthinta olunye umsebenzi.

Ukuhlaziywa kwedatha, inezici eziyisisekelo zokuziphendulela kanye nokucwaninga okungafunwa ngumuntu, ekuboneni kuqala kunezinye izici ezithakazelisayo kakhulu engizikhethayo ukubona esinye isikhathi, ngoba ama-plugin we-Ftools afaka ukufometha komhlaba, i-hydrological phakathi kwabanye.

Qgis Ama-plugin angeziweNjenganoma yimuphi isicelo GPL, inzuzo yakho plugin kancane okwenza umphakathi (siqala ngokunenzuzo bekungekho Java), ngokwakhona kuletha eziyisisekelo futhi zibonakala zimbalwa kodwa akuzona njengoba elula njengoba zibonakala: loadable izingqimba WFS, ukuthekelisa MapServer, uthwebule isikhathi bazihlela ngokubambisana, engeza ukwesekwa ekubukweni njengoba enyakatho, isikali kanye nelungelo, umbhalo comma-delimited, has a DXF Converter SHP plugin for georeferencing izithombe, console GPS, python console, igridi izixhumanisi , njll. Kodwa into engcono kakhulu yindlela yokulayisha ama-plugins we-Grass ayingqinamba ehlukile. Ngokufana kwenzekani nge gvSIG futhi Sextant nakuba ukuvuthwa Utshani kuyinto ehloniphekayo, omunye omdala GIS amathuluzi.

Ngokuthakazelisayo OGR lokuguqulela, ungakwazi ukuguqula izingqimba phakathi ngetakhiwo letehlukene, ezifana SHP, DGN, GPX, GML, CSV, KML, MapInfo futhi BD isikhala nge ODBC, MySQL, PostgreSQL, phakathi kwabanye.

Kokuhle kakhulu: i-dxf kuya ku-shp ne-kml kuya ku-dxf, eyisisekelo kodwa engenziwanga ngezinye izinhlelo zokukhokha.

Imisebenzi eyisisekelo, njengamanye amathuluzi, ungakha amabhukimakhi wendawo, amaqoqo ezendlalelo, izendlalelo zinokulawulwa okungenani okuyisilinganiso nesisindo esiphakeme, okulula ukwengeza izinhlelo zokuhlela nokuhlela; uma ngabe izingxenye ze-shp, uma zine-prj, i-Qgis ikhulula lolu lwazi. Izinqubo eziningi zifaka ibha yokuqhubeka, esicabanga ukuthi inhle kakhulu.

Qgis Kuyathakazelisa kakhulu ukuthi izimfanelo zezinto zenziwe kanjani, kusukela kuphaneli elifanayo kukhona amathebhu ezakhiwo ezijwayelekile, isabonakaliso, imethadatha, amalebuli, izenzo kanye nezimfanelo zamathebhu; konke kungagcinwa njengesitayela se-.qml futhi silayishwe ukuyifaka kwezinye izendlalelo. Futhi leli tafula liyaleza futhi ungakwazi ukulungisa ububanzi balo nokuphakama ukunambitha. Ngisho lephaneli kanye nabanye bangavulwa njengesicelo esihlukile.

i-quantum gis Iphinde igxile ekusebenzeni okubonakala kubonakala kulula kodwa kunomsebenzi omkhulu, njengokulinganisa kwemikhawulo eqhubekayo, eboniswa kwipaneli yamathebhu, efaka ibanga lesigaba ngasinye.

Ukufinyelela nokuhlela idatha

Ungakwazi ukulayisha idatha ye-vector shp, i-gml, i-Mapinfo ne-ddf, nakuba ungaguqula idatha kusuka kwamanye amafomethi nge-converter ye-OGR. Ukwengeza izendlalelo ze-vector nge-WFS ne-PostGIS. I-Rescatable, ikuvumela ukuthi ucacise ukulinganisa uhlamvu uma ulayisha ungqimba.

Ngokuqondene nezendlalelo ze-raster, isekela okuningi, ngaphandle kwe-WMS. Ukwengeza, kuhlanganisa ukufunda ama-OGC WFS, WCS, CAT, SFS, namazinga we-GML.

Ukudala izendlalelo ze-vector ezintsha kungenziwa ngamafomethi we-OGR noma i-Grass. Amaphrojekthi agcinwa njenge-XML ne-qgs extension, lapho ukuguqulwa kwezendlalelo kugcinwa kwisitayela se-GvSIG.

Ngokuqondene ukuhlela idatha, kuphrojekthi izakhiwo zigcinwa Ukucaciswa njengoba Ukudidiyela uhlelo, amayunithi, ikwazi idesimali, unike amandla ukuhlela topological, amandla noma nokukhawulela ngemapholigoni agqagqene ungqimba efanayo nemibandela khalisa (uhlobo ukubekezelelana) kwesendlalelo ngasinye esitholakalayo kule phrojekthi. Lezi zinsuku ziyathakazelisa, nakuba ngidumale ukuthi inxenye kuphela nenketho ye-vertex. Nakulokhu, i-Grass kumele ibe yilezi zizathu.

Ngazama ukuhlela ungqimba, ngifaka i-vertex, kodwa ngithole ukuthi ihamba kancane, ngaphandle kokuthi kwakudingeka ukuthi ungeze izinketho zokuchofoza (ngiyaxolisa ngokuzikhukhumeza kwami, kungowokuqala ngidlala le thoyizi). Ngizoyibona ngemva kokulayisha amathuluzi okuhlela eGrass. Futhi akubonakali ukuthi kukhona ithrekhi uma eziningana zihlela ungqimba ngesikhathi esisodwa, ngubani ozuza kuqala. ugh!

Ukukhishwa kwedatha

Ngenhloso yokuphuma okusheshayo, kunenketho yokugcina umbono njengesithombe, ne-plugin yokunyathelisa okusheshayo, kodwa ngokungafani ne-gvSIG, ayikho isilawuli se-style ye-ArcView; kodwa umqambi wokuphrinta obonakala kimi ngandlela-thile uthathwe ezinhlathini, nakuba kuvumela ukulayisha ama-dataframes, amalebula, amabhokisi kanye nezimpawu, futhi ungakha izingqikithi eziningana zephrojekthi, angizange ngithole indlela yokuzigcina njengezifanekiso; le ncwadi ithi kungenzeka. Ngicabanga ukuthi kuma-plugin we-Grass kukhona izinto ezingcono kulezi zinhloso.

I-Quantum gis ne-ArcGIS

Yebo, ngemuva komhlaka olandelayo.

  15. Angikwazi ukungena kumafayela we-kml kusuka ku-5.0 inguqulo ye-google komhlaba aquantum gis noma ubani ongangisiza ukuthi i-quantum gis ver i-1.2
    I-gracias

  16. Yebo, bayabasekela. Ngomqondo wokude, i-Qgis isebenza kahle kakhulu nge-Grass ne-gvSIG ene-Sextant.

  17. i-hol, ngifuna ukwazi ukuthi lezi zinhlelo zifana ne-Qgis, i-gvgis noma utshani lisekela amafayela we-serial (shp, ithebhu .......) futhi ingalawulwa ngokubona okude?

  18. Hola umfundi Soi umsebenzi Geomatica nje ukuphequlula ngathola ngalokhu inguqulo entsha imahhala futhi ngingamnika zonke izinhlangothi nge-USB opsion kuhle abafundi Ngikusho lokhu njengoba umfundi futhi omuhle mina ngempela Guto le 3 izinhlobo amathuluzi d kodwa plus QGIS okungukuthi kuthi akufane nokwenzeka Argis nokuhle geoprocessing indaba kuphela wenze elula sesikhashana ekhaleni uma kukhona opsion lapho ungenza kokubhafa amaningi ... aver uma ngithumela izibonelo zendlela ukulanda izithombe google umhlaba anamagama ka avenida..grasias ..

  19. Ngenxa yalokhu uya:
    I-add-ons / i-OGR yomguquleli / sebenzisa umguquli we-OGR woshothi

    Khona-ke ukhetha amafayela okuqala (umthombo), ukhetha i-kml format, nama-flame

    Khona-ke, ngezansi ukhetha indawo (umgomo), bese ukhetha ukuthi uyabashintshela ku-shp

  20. umbuzo ezinsukwini ezimbalwa ezedlule ufake i-qgis Ngifuna ukwazi uma kungenzeka ukuguqula amafayela we-kml kuya shp nokuthi ngabe

  21. Uqinisile iTuxcan, ijubane lenqubo ye-Qgis libonwa kangcono kune-gvSIG. Ukuze ube amathuluzi wamahhala, asekhulile kakhulu futhi manje ngalawa ungasebenza kungathi uhlelo lwangasese.

  22. Ngithanda kakhulu kokubili amaphrojekthi we-GvSIG kanye ne-Quantum GIS, okubili okuthembisa izici eziningi nezakhiwo kwimisebenzi ye-GIS. Kodwa-ke, ngezinye izikhathi ukuhamba kancane kwezicelo ze-JAVA, okungafani kancane kusuka ku-interface ye-QGIS ecacile, kumele kugcizelelwe. Into enkulu nge-QGIS yiPython API yayo yokuhlela izinhlelo zokusebenza zedeskithophu, uxhumano lwayo ku-GRASS GIS nokusekelwa kwamafomethi ahlukahlukene. I-gvSIG I igcizelela ukusebenza kwayo okukhulu nge-SEXTANTE GIS kanye nezinketho ezinhle zokuxhumana kumadivaysi eselula, ukubukwa kwe-3D, ukushicilelwa, kodwa ngifakazela i-LENGTH ye-execution yayo. Kubuthakathaka bobabili amathuluzi ukubunjwa kwamabalazwe, ngoba kuze kube manje kuncane kakhulu. Ngicabanga ukuthi kuhle uma kungenzeka ukuthi kufaka phakathi amathuluzi wokuhlela we-KOSMO noma i-OpenJUMP, engiyitholile ephelele futhi enobungane.

    Zombili amaphrojekthi zikhulu futhi zikhuthaze ngendlela engavamile isofthiwe yamahhala ye-GIS, yingakho inkululeko yesofthiwe, ukusivumela ukuba sikhethe amathuluzi ahlangabezana nezidingo zethu.

  23. Ngokuzithoba, kuhle ukuthola ulwazi lwebhulogi yakho. . . Siyakuhalalisela kusuka ePatagonia Argentina
