I-OpenGeo Suite: Isibonelo esihle se-GIS Software ukucabanga ngobuthakathaka besimo se-OSGeo

Namuhla, okungenani endaweni yezwe, wonke umuntu onguchwepheshe ongathathi hlangothi uyabona ukuthi isoftware yomthombo ovulekile ivuthiwe njenge-software yezentengiso, futhi ngezinye izindlela iphakeme.

Isu lamazinga lisebenze kahle kakhulu. Yize ukulinganiswa kwayo kokuvuselelwa ebusweni bamandla okufunwa ukuziphendukela kwezobuchwepheshe kungabazeka, mhlawumbe bekuyikho okwakha izisekelo zokuqinisekisa impumelelo kweminye imizamo efana nomphakathi, indlela yefilosofi, ezomnotho neminye imibono esetshenziselwe ukuxhasa imodeli, okuyinto ekugcineni nayo edingekayo.

Kodwa-ke, ukuthengisa izixazululo ze-Open Source akulula emabhizinisini noma ezindaweni zikahulumeni, ngenxa yezizathu eziningi ezivela emncintiswaneni kodwa futhi njengomphumela ongenakugwemeka wobuthakathaka bemodeli, okumele iguquke futhi ihlangane nesoftware ephathelene. Abenzi bezinqumo bazibuza imibuzo efana nale:

• Uma ngolunye usuku ekuseni kuvela inkinga kithi ngenxa yokuvuselelwa kwamanye amapulatifomu, ezicini ezifana nokuphepha, ngubani ophendulayo lapho sidinga ukwesekwa, futhi ngamanani entengo ukuze usenze isabelomali?

• Njengoba kunikezwe ububanzi bezinye izindlela zolimi, imitapo yolwazi, izixazululo zamakhasimende, izixazululo zewebhu, iyiphi inhlanganisela okufanele siyikhethe ukuqinisekisa ukuhambisana? quasi inani?

I-OpenGeo Suite yisixazululo esingasebenzisi kuphela ukuvuthwa okugcwele kwamathuluzi atholakalayo, kepha futhi ihlose ukuphendula kulabo buthakathaka kwimodeli. Ngaphezu kokunikeza umphakathi isisombululo abangathuthukisa ngaso izinhlelo zabo zentuthuko, kwakha umucu ofanayo wezinto ezithintekayo ukuqondisa ukuvela kwazo futhi, ezinkampanini, i-OpenGeo Suite inikeza ubucayi obudingekayo ukunquma ngomthombo ovulekile. Yize zikhona ezinye izinkampani, ngemuva kwesikhathi sokuhlola le ndlela enye anginakho okunye engingakwenza ngaphandle kokubona amandla aphezulu nobuchule babacabangi ngemuva kweBoundless, inkampani edale lesi sixazululo.

Ake sibone okunye okushiwo yi-OpenGeo Suite indlela:

Yimaphi amathuluzi afakwa yi-OpenGeo Suite?

Ukuba nezinketho eziningi kangaka zezixazululo akukubi, kujwayelekile, noma ngabe kuyinkimbinkimbi ukuthi ungaqinisekisa kanjani ukukhethwa kwamathuluzi kuzinqubo zokukhiqiza ezihlanganayo. Ukukhetha okungalungile kungabiza kakhulu uma sibona lapho sesivele sitshale imali emizamweni yocwaningo, intuthuko, ukuqeqeshwa futhi ngaphezu kwakho konke isikhathi esingatholakali.

Isibonelo, kuphela ngolimi lwentuthuko sinendida ebangelwa izidingo zomphakathi, iningi lazo lenza okufanayo, ezinye zilingisa kolunye ukunambitheka, ezinye zinezici ezihlukile emisebenzini elula esingathanda ukuba nazo zonke. Ake sibone lokhu kwehlukaniswa ngokusebenza nangezilimi; noma kufanele ngithembeke, ukuhlukaniswa ngezigaba akukhethi kuphela futhi kwezinye izimo kunzima ukuhlukanisa umngcele:

• Ezingeni lamakhasimende, okuyisimo esithandwa kakhulu, yilezi: QGis, Grass, ILWIS, SAGA, Kapaware, based on C ++. gvSIG, Jump, uDIG, Kosmo, LocalGIS, GeoPista, SEXTANTE, ngokususelwa kuJava. I-MapWindow yengxenye yayo ku-ActiveX ngokususelwa ku .NET.
• Kumitapo yolwazi sinayo: GDAL, OGR, PROJ4, FDO, GEOS ku-C ++. Ama-GeoTools asuselwa kuJava, WKB4J, JTS, Baltic. NTS, GeoTools.NET, SharpMap ngaphezulu .NET.
• Ngokuqondene nezixazululo zewebhu, namuhla ezithandwa kakhulu: I-MapServer, i-MapGuide OS ku-C ++; I-GeoServer, iDegree, iGonetwork kuJava. I-OpenLayers, iLeaflet neKa-Map kuJavascript, mapFish ePython, MapBender ku-PHP / Javascript.
• Ngokuphathelene nemininingwane, iPostgres ibaluleke kakhulu, yize zikhona nezinye izixazululo.

Lokhu okungenhla kusikhombisa ukuthi kungenzeka ukufaka uhlelo cishe kunoma iyiphi imvelo. Ngaphezu kwalokho, abaningi babo, yize bezalwa ngolimi olulodwa, manje sebesekela abanye. Abaningi babo nabo bazalwa njengamakhasimende kepha bayakwazi ukuphatha idatha yewebhu futhi ezimweni ezinjenge-Open Layers kungenzeka ukuthi kuthuthukiswe endaweni yewebhu cishe konke okwenziwa kuthuluzi leklayenti.

Yikuphi ukuhlanganiswa kwesoftware yamahhala ongayisebenzisa?

I-OpenGeo suite inqume QGis Njengeklayenti ledeskithophu, usuvele ufanelwe isigaba sendatshana kumaGeofumadas manje. Kwiwebhu, bakhethe i-GeoServer njengeseva yedatha esebenza ku-Tomcat, Jetty njengemvelo yesikhathi sokusebenza seJava, iGeoWebCache ye-tessellation ne-OpenLayers njengomtapo wezincwadi, noma ngabe le ndlela yokugcina ayinakho ukubhaliswa okuyimpoqo, kubhekwa izixazululo ezinjengeLeaflet ekhula ngempumelelo enkulu, ikakhulukazi ngenxa yemodeli yayo ngokususelwa kuma-plugins namandla ayo ngezinhlelo zokusebenza zeselula. Bona ukuthi ungadlula kulayini owodwa wolimi kepha ngithanda ukubona umatrix wokuhlaziya okuholele kule ncazelo.

Masibe sobala, noma ngubani angazisebenzisa lezi zixazululo ngawodwana. Okuqukethwe yi-OpenGeo yisifaki esinezinguqulo zalezi zinto ngokuthuthuka ukwenza imizila eyisicefe isebenze kangcono; Ngokwesibonelo:

• Isifaki senza umhlangano ucoceke. Ukwazi ukukhetha ukuthi iziphi izinto ozozifaka, uzisuse noma uzikhiphe. Kulabo ababhekane nenjini yesikhathi sokusebenza seJava nge-Error Error 503 bazokwazi ukuba usizo.
• Kunezifaki ezihlukile: for IWindows, Mac OS X, CentOS / RHEL, Fedora, Ubuntu, kanye neServers Application.  
• Uhlobo lwakamuva lwe-4.02 liletha iPostgreSQL 9.3.1, iPostGIS 2.1.1, iGeoTools 10, iGeoServer 2.4.3 neGeoWebCache 1.5; futhi isekela i-OpenLayers 3.
• Izixhumanisi eziqondile zenziwa kumenyu yokuqala ukumisa noma ukuqala i-GeoServer nePostgres; futhi ukuphakamisa i-shapefiles data upload interface yomsebenzisi ku-Postgres (shp2psql) kanye nokufinyelela ku-database ye-PostGis (PgAdmin).
• Futhi kwimenyu yokuqala kukhona ukufinyelela kwe-localhost, ethi kule nguqulo isuse i-interface yekhasimende yenguqulo 3, nephaneli yokulawula ehlanzekile ebheke ezinsizakalweni ze-GeoServer, GeoWebCache kanye neGeoExplorer
• Lo mkhiqizo, i-GeoExplorer ukukhula okuhlaba umxhwele kwamaBoundles asuselwa ku-GeExt esebenza njengesibukeli sedatha ye-GeoServer, evumela ukulayishwa kwedatha kusuka kufayela lasendaweni noma kusuka kugcinwa kwedatha, ukukwazi ukumisa umbala, ubukhulu bomugqa, ukusebenzela obala, ukufaka ilebula, kufaka phakathi imithetho nokugcina ngqo kufayela lesitayela se-geoServer (sld). Akekho engqondweni yakhe olungile osebenza lokhu kukhodi emsulwa futhi iGeoExplorer yisixazululo esihle kakhulu -yize enza izinto eziningi-.

• Uhlobo olufakiwe lwe-GeoServer lufaka isixhumanisi sokungeniswa kwedatha, ukukwazi ukudala imvelaphi kusuka kuzendlalelo zomumo wendawo, kufaka phakathi i-PostGis idatha engasuswa ngayo isuswe kwesinye isuke iye kwenye ifakiwe kusuka ku-Localhost kuya kwinsizakalo ebanjelwe; Kuyathakazelisa ukuthi lokhu kulayishwa kwedatha kusombulula izinkinga ze-OGR2OGR okuthi, ngaphandle kokuthi kwenziwe ngomugqa wekhonsoli, baphonsa ubunzima lapho kulayishwa ungqimba lwama-multipolygon, ngoba okuzenzakalelayo kuyi-polygon elula.
• Kulokhu, izinsizakalo ze-WPS ziyavela ngoba kunketho yokufaka nginqume ukuzihlanganisa.
• Izengezo ze-GeoServer ezifana ne-CSS Styling, CSW, Cloustering nokusekelwa kwemitapo yolwazi ye-GDAL zingangezwa ngesikhathi sokufaka. Kukhona ne-Add-on yePostGIS esekela amafu wephuzu ku-database futhi i-GDAL / OGR nayo ingafakwa njengeklayenti. Okonjiniyela kunenketho yokufaka iWebapp SDK ne-GeoScript.
• Ngokungafani nenguqulo yami ebanjelwe kuseva, ngiyabona ukuthi kunemithombo eminingi yedatha, engangezwa ngokuqinisekile kepha esimweni senguqulo eza ne-OpenGeo Suite iletha umbhalo ohlukaniswe ngamakhoma, i-H2, i-H2 JNDI, i-SQL Server, I-OGR, i-Oracle kanye nedlanzana lamathuba kumvelaphi ye-raster.

Kuthiwani ngeQgis?

• Okuhamba phambili, kwiQgis bakhe i-plugin enkulu ebizwa nge-OpenGeo Explorer ongasebenzisana nayo nedatha ye-Postgres kanye ne-GeoServer. Ukusuka lapha ungahlela ama-slds, uhambise izingqimba, amaqembu wesendlalelo, uhlele amagama, ususe, ubuke izindawo zokusebenza, izingqimba ezifakwe kunqolobane, njll.
• Uma kususwa ungqimba, i-sld iyasuswa; Konke lokhu kuyalungiswa futhi ekugcineni kufinyelela umsebenzi kwiklayenti elilawula okungaphezulu, lokho kuvunyelaniswa kungasebenzisa i-REST API.
• Okwamanje, engenayo i-shp2psql kepha akumangazi ukuthi kamuva bayayihlanganisa kulelo phaneli elifanayo, mhlawumbe lisobala njenge-Spit plugin okuthi, ngokungafani ne-UI, egcina ukuxhumana, ingalayisha izendlalelo eziningi ngobuningi, ibha yokuqhubeka ingaphezulu imilayezo yephutha engokoqobo neqondakalayo.

Nale Suite ye-OpenGeo ayisho ukuthi le iresiphi yomlingo. Kepha ngokuqinisekile izosusa ingxenye enkulu yomphakathi kulokhu okuthandayo, ikakhulukazi njengoba izinkampani ezithengisa izifundo zizokhetha ukufundisa lo mzila oqinisekisa ijika elifushane lokufunda.

I-combo ihambisana namanye amathuluzi angafakwa kwisiphakeli.

Yithinta kanjani i-OpenGeo Suite

Sizobona ukuthi lokhu kunomthelela onjani emphakathini, ngoba ngemuva kweBoundless kunabantu abanolwazi oluningi kulo mkhakha, ababambe iqhaza ekwakhiweni kwamathuluzi nemitapo yolwazi manje eyenza lo mkhakha uzinze. Kepha ngaphezu kwakho konke ngokuqeqeshwa kwezamabhizinisi kanye nokumakethwa kwensizakalo, okuvame ukuchitheka kusuka ezingeni lobuchwepheshe. Ukukhuluma okungenani okuyisithupha:

• U-Eddie Pickle noKen Bossung, abasunguli be-IONIC, eyathengwa yi-ERDAS ngo-2007 manje eseyiphethwe nguLeica.

• U-Andreas Hocevar noBart van den Eijnden, ababhapathiziwe ekuthuthukiseni i-OpenLayers 2 ne-GeoExt.

• UVictor Olaya, osishiyele lelo lifa le-SEXTANTE,

• UPaul Ramsey, we-initiators of PostGIS.

Enye nomthelela omuhle iyona Okusemthethweni inkampani enkulu ukuthi lalizoba yisilwane emakethe okuyinto kuhlale risk-, kuletha Okusemthethweni mncintiswano ngokumelene izinkampani emkhakheni nokuphathelene ezindaweni ezifana ukwesekwa, ukuthembeka, ukuphepha kanye ukulawulwa kwekhwalithi phezu kwentuthuko.

Izinsizakalo ezinikezwa yi-Boundless, kusuka ekuthutheni kwepulatifomu kuya ezinsizakalweni zonyaka zokusekelwa, zibonakala ngathi ziyahambisana nemakethe yebhizinisi neyezikhungo eziqonda kancane umehluko phakathi kokuthola ukwesekwa kwendawo nokuxhaswa kwebhizinisi. Le makethe akufanele ibe lula, kepha sibona ngamehlo amahle ukuthi izikhungo zikhula kanjani emcabangweni, zikwazisa ukuthuthukiswa kwesoftware nolwazi njengempahla, ngakho-ke zikwazile ukusuka ekunikezeni imisebenzi yomakhenikha bezimoto kubashayeli bazo, kuya ekuqashweni komshuwalense nezinsizakalo ezikhethekile yezinkampani zokusabalalisa.

Kumodeli yomthombo ovulekile, kunethuba lawo wonke umuntu. Ngakho-ke okuhlinzekwa okungenamkhawulo kukhona, nethuba lokukwenza ube ngumlingani; ngaphezu kwamandla alabo abafisa ukuthuthukisa ikhono labo lokuthengisa izinsizakalo maqondana nokuqaliswa, ukuqeqeshwa, ukusekelwa noma ukuthuthukiswa. Lesi sibonelo sibonakala silusizo kithina futhi sinezifundo ezinhle esingazifunda nokugcwalisa umzamo i-gvSIG Foundation ehola ngenye indlela, esizokhuluma ngawo kwesinye isenzakalo.

Landa i-OpenGeo Suite.
