Quantum GIS, umbono wokuqala

Qgis Uma abangane be-gvSIG bagcina isithembiso sabo, ngoMsombuluko ozayo ngoJulayi 27 sizoba nesitebele esingu-1.9. Kuze kube manje ukuhlolwa kube kuhle, ngokusho kwevolumu ebonwa kwifayili ye- uhlu lokusabalalisa. Ngenkathi uMsombuluko ufika, lapho nginethemba lokuthola ukwaneliseka ngokuhalalisela ukuhambisana negama, ngilimaze ukungalali okuqinisekile abathuthukisi okufanele bakuthwale, ake sibheke i-Quantum GIS enjengale ngamehlo enyoni.

I-QGIS yathuthukiswa ku-C ++ kusetshenziswa i-Qt toolkit, isebenza ku-Windows, Mac ne-Linux. Iphrojekthi yavela ngoMeyi 2002, ngokwesekwa kwezilimi ezingama-26 kanti ilayisense yayo iGPL.

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 kanye ne-interface design iyona ehlengeka kakhulu, ayikuthinti ukusetshenziswa, kepha ithinta ukunambitheka kwezinkampani (kuyathengiswa) lapho ukunikela. Ukubukeka 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 iGrass ngemisebenzi eminingi lelo thuluzi elisungule kahle, inhle kakhulu ngokungaphindi imizamo. Lapho uqala i-QGIS futhi ungayitholi ifakiwe, iphakamisa isexwayiso; kulokhu ngenza isibuyekezo ngaphandle kokufaka i-Grass. Ngenkathi ngifuna ukulayisha idathasethi yeGrass, ngoba yayingafakwanga, uhlelo luvaliwe, ngakho-ke angincomi ukulusebenzisa ngaphandle kokufaka womabili amathuluzi.

Qgis Izinqamuleli, Imiyalo eminingi inencwadi eyabelwe, efana nokuthi umsebenzi ungalayishwa ngokucindezela le ncwadi. Lokhu kuyasebenza kakhulu, ngiyakhumbula ukuthi ku-AutoCAD bekungokunye kwamaqhinga amahle kakhulu lapho cishe yonke imiyalo yenziwa ngekhibhodi.

Ukubuka konke, kuphaneli yesobunxele imephu ebonisa indawo yokuthunyelwa, ngokuvumelanisa kuwo womabili amathrekhi. Ilusizo kakhulu, ungakhetha ukuthi iziphi izendlalelo ofuna ukuzibona ekubukweni konke, futhi ingaphonswa njengewindi ezintantayo ngosayizi ohlukile.

QgisUhlaka olusemaceleni, luhle nje, ungahudula ama-plugins njengamalebula ngaphambili, angenziwa entanta, futhi ngenkinobho elula yesokudla kusebenze noma kungasebenzi. Futhi ukuphathwa kobubanzi kulula ukuhudula hhayi kuphela kuphaneli yesobunxele kepha nakwaphansi.

Iphaneli eliphansi, lapho kukhonjiswa itafula lemfanelo, livela endaweni, kepha futhi lingantanta. Isebenza kahle kakhulu, inezinketho zokusondeza emigqeni ekhethiwe bese uguqula ububanzi bamakholomu ngokuhudula okulula kwegundane. Futhi kufreyimu engezansi inokusesha nokukhetha imisebenzi, efana nokuthi iManifold GIS yenza kanjani, ngaphandle kwebha yomumo elula.

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 yiluphi uhlelo lokusebenza lwe-gpl, inzuzo yalo ikuma-plugins umphakathi awenza kancane kancane (yize kunenzuzo yokungabi seJava), ngokuzenzakalela kuletha izisekelo futhi zibonakala zimbalwa kepha azilula njengoba zibonakala: zingalayishwa Izendlalelo ze-WFS, ukuthekelisa iMapServer, bamba ukuxhumanisa, engeza izinsiza ekubukweni okufana nenyakatho, isikali nelungelo lobunikazi, umbhalo onqunywe ngamakhoma, une-dxf to shp converter, i-plugin ezithombeni ze-georeference, i-gps console, i-python console, i-coordinate mesh , njll. Kepha into enhle kakhulu inketho yokulayisha ama-plugins weGrass ayisihloko esihlukile. Ngokufana nokwenzeka nge-gvSIG ne-Sextante yize ukuvuthwa kwe-Grass kuhlonishwa, elinye lamathuluzi amadala we-GIS.

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 eyisisekeloNjengamanye amathuluzi, ungakha amabhukhimakhi ezindawo, amaqembu ezendlalelo, izingqimba zinokulawulwa okuncane nobukhulu bokusondeza, ukukhululeka kokungeza amasistimu wokuxhumanisa nokuqagela; uma kwenzeka kunezingqimba ze-shp, uma zine-prj, u-Qgis uhlenga lolu lwazi. Izinqubo eziningi zifaka ibha yenqubekela phambili, esicabanga ukuthi yinhle kakhulu.

Qgis Kuyathakazelisa ukuthi izimfanelo zezinto zilungiswa kanjani, ngoba kuphaneli efanayo kunamathebhu ezakhiwo ezijwayelekile, izimpawu, imethadatha, amalebula, izenzo kanye nezimpawu zamathebula; konke kungagcinwa njengesitayela se-.qml futhi kulayishwe ukuze kusetshenziswe kwezinye izingqimba. Futhi leli thebula liyantanta futhi ububanzi nokuphakama kwalo kungalungiswa ukunambitha. Ngisho nale phaneli namanye angavulwa njengohlelo lokusebenza oluhlukile.

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

Ungalayisha i-vector data shp, gml, Mapinfo ne-ddf, yize idatha evela kwamanye amafomethi ingaguqulwa ngesiguquli se-OGR. Ngokwengeziwe izingqimba ze-vector nge-WFS ne-PostGIS. Ukuhlenga, kukuvumela ukuthi ucacise ukufaka ikhodi kuhlamvu lapho ulayisha isendlalelo.

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

Ukwakha izendlalelo ezintsha zama-vector zingenziwa ngamafayela womumo we-OGR noma ngeGrass. Amaphrojekthi agcinwa njengeXML enwetshiwe ngama-qgs, lapho ukuhlelwa kwesitayela se-gvSIG kugcinwa khona.

Ngokuqondene nokuhlelwa kwedatha, imininingwane efana nohlelo lokuxhumanisa, amayunithi, ukunemba kwedesimali, ukunika amandla ukuhlelwa kwe-topological, imvume noma umkhawulo wamapholigoni agqagqene kwisendlalelo esifanayo nezimo ze-snap (uhlobo ukubekezelelana) kusendlalelo ngasinye esitholakala kuphrojekthi. Lokhu kwamuva kuyathakazelisa, noma ngabe ngidumele ukuthi inesigaba kanye nenketho ye-vertex kuphela. Ngiyagcizelela, iGrass kumele ibe yisizathu salokhu.

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 ngemuva kokuthi ngilayishe amathuluzi wokuhlela weGrass. Futhi akubonakali kunethrekhi uma abaningana behlela isendlalelo ngasikhathi sinye, noma ngubani osindisa kuqala ukunqoba. ugh!

Ukukhishwa kwedatha

Ngezinhloso zokukhipha okusheshayo, kunenketho yokonga ukubuka njengesithombe, ne-plugin yokuphrinta okusheshayo, kepha ngokungafani ne-gvSIG, ayinayo isilawuli sesakhiwo sesitayela se-ArcView; kepha umqambi wokuphrinta obonakala ethathwe kancane ezinweleni, yize kuvumela ukulayisha amafreyimu edatha, amalebula, amabhokisi nezimpawu, nokwenziwa okuningana kungadalelwa iphrojekthi, angitholanga ukuthi ngingazigcina kanjani njengezifanekiso; imanuwali ithi kungenzeka. Ngicabanga ukuthi kukhona izinto ezingcono kuma-Grass plugins ngalezi zinhloso.

I-Quantum gis ne-ArcGIS

Yebo, ngemuva komhlaka olandelayo.
