OpenGeo Suite: Chitsanzo chabwino cha GIS Software kuganizira zofooka za mtundu wa OSGeo

Masiku ano, m'dera la geospatial, akatswiri onse osagwirizana nawo amadziwa kuti pulojekiti yotseguka imakhala yokhwima ngati pulogalamu yamalonda, ndipo m'njira zina zimakhala zopambana.

Njira zoyeserera zidagwira ntchito bwino kwambiri. Ngakhale kusinthika kwake koyenera pamaso pa mphamvu zomwe kusinthika kwaukadaulo kumafunikira kukayikitsa, mwina ndi zomwe zidayika maziko oti zitsimikizire kupambana pazinthu zina monga anthu ammudzi, nzeru zafilosofi, zachuma ndi malingaliro ena omwe adagwiritsidwa ntchito kutsimikizira mtunduwo, zomwe pamapeto pake ndizofunikanso.

Komabe, kugulitsa mayankho a Open Source sikophweka m'mabizinesi kapena m'malo aboma, pazifukwa zambiri zomwe zimayamba chifukwa champikisano komanso chifukwa chazotsatira zofooka za mtunduwo, zomwe ziyenera kusintha ndikukhala limodzi ndi pulogalamu yamalonda. Opanga zisankho amadzifunsa mafunso ngati awa:

• Ngati m'mawa wina tikuwona vuto lomwe limabwera chifukwa cha zosintha za mapulaneti ena, muzinthu monga chitetezo Ndani amayankha pamene tikusowa chithandizo, ndipo ndi mtengo wotani womwe umachokera?

• Popeza pali mitundu ingapo yazilankhulo, malo owerengera, mayankho amakasitomala, mayankho apawebusayiti, kodi ndi njira ziti zomwe tingasankhe kuti zitsimikizirane? pafupifupi chiwerengero?

OpenGeo Suite ndi yankho lomwe limangogwiritsa ntchito mwayi wokhwima pazida zomwe zilipo, komanso cholinga chakuyankha pazofooka zazitsanzo. Kuphatikiza pakupatsa anthu ammudzi yankho lomwe angalimbikitsire njira zawo zachitukuko, zimapanga ulalo wofanana pazinthu zomwe zimakhudzidwa ndikuwongolera kusintha kwawo ndipo, m'makampani, OpenGeo Suite imapereka chidwi chofunikira posankha gwero lotseguka. Ngakhale pali makampani ena, nditatha nthawi yoyesa njirayi sindingachitire mwina koma kuzindikira kuthekera komanso luso la oganiza kumbuyo kwa Boundless, kampani yomwe idapanga yankho ili.

Tiye tiwone zina mwa zomwe OpenGeo Suite ikuwonetsera:

Zida zotani OpenGeo Suite zikuphatikizapo?

Kukhala ndi mayankho ambiri siabwino, si kwachilendo, ngakhale kuli kovuta kuti zitsimikizire kusankha zida zogwirira ntchito limodzi. Kusankha kolakwika kumatha kukhala kopezera ndalama ngati tingazindikire kuti tayesetsa kale kafukufuku, chitukuko, maphunziro komanso koposa zonse zomwe sizingabwezeretsedwe.

Mwachitsanzo, pokhudzana ndi chilankhulo chachitukuko tili ndi chithunzi chotsatira cha zosowa za anthu ammudzi, ambiri amachita chimodzimodzi, ena amatsata kukoma kwina, ena okhala ndi machitidwe apadera m'njira zosavuta zomwe tikanafuna kukhala nawo onse. Tiyeni tiwone kulekanaku ndi magwiridwe antchito ndi zilankhulo; Ngakhale ndiyenera kunena zowona, kugawa magulu sikungokhala kokha ndipo nthawi zina kumakhala kovuta kusiyanitsa malire:

• Pamlingo wamakasitomala, womwe ndi nkhani yotchuka kwambiri, ndi: QGis, Grass, ILWIS, SAGA, Kapaware, kutengera C ++. gvSIG, Jump, DIG, Kosmo, LocalGIS, GeoPista, SEXTANTE, kutengera Java. MapWindow gawo lake pa ActiveX kutengera .NET.
• M'malaibulale tili: GDAL, OGR, PROJ4, FDO, GEOS pa C ++. GeoTools yochokera ku Java, WKB4J, JTS, Baltic. NTS, GeoTools.NET, SharpMap pa .NET.
• Pazomwe zothetsera mawebusayiti, zomwe lero zikuphulika: MapServer, MapGuide OS pa C ++; GeoServer, Degree, Geonetwork pa Java. OpenLayers, Leaflet ndi Ka-Map ku Javascript, mapFish mu Python, MapBender mu PHP / Javascript.
• Ponena za maziko, Postgres ndizovuta kwambiri, ngakhale pali zothetsera zina.

Zomwe zili pamwambazi zikuwonetsa kuti ndizotheka kukhazikitsa dongosolo pafupifupi kulikonse. Komanso, ambiri a iwo, ngakhale adabadwa mchinenero chimodzi, tsopano akuthandiza ena. Ambiri mwa iwo adabadwanso ngati makasitomala koma amatha kuwongolera mawebusayiti ndipo ngati Open Layers ndizotheka kukhala patsamba lawebusayiti pafupifupi chilichonse chomwe chimachitika mu chida cha kasitomala.

Kodi kuphatikiza kwa mapulogalamu aulere omwe angagwiritsidwe ntchito?

Otsatira OpenGeo adasankhidwa ndi Qis Monga kasitomala wa desktop, yemwe pano akuyenera kukhala ndi zolemba mu Geofumadas. Pa intaneti, adasankha GeoServer ngati seva ya data yomwe imagwira ntchito pa Tomcat, Jetty ngati malo othamangitsira Java, GeoWebCache yopangira tessellation ndi OpenLayers ngati laibulale, ngakhale njira yomalizayi ilibe kulembetsa kofunikira, poganizira mayankho monga Leaflet yomwe ikukula bwino, makamaka chifukwa cha mtundu wake. kutengera Mapulagini ndi kuthekera kwake ndi kugwiritsa ntchito mafoni. Onani kuti mutha kupita pamzere umodzi wa chilankhulo koma ndikufuna kuwona mtundu wa kusanthula komwe kwatsogolera kukutanthauzira uku.

Tidziwike, aliyense atha kugwiritsa ntchito njirazi payekhapayekha. Zomwe OpenGeo ili ndi chokhazikitsa chomwe chimakhala ndi mitundu yazinthuzi ndizopangitsa kuti zizolowera zizigwira bwino ntchito; Mwachitsanzo:

• Wowonjezera amapanga msonkhano kukhala waudongo. Kukhala wokhoza kusankha zida zomwe mungayikemo, kuchotsa kapena kuchotsa. Kwa iwo omwe agwira ntchito ndi injini yothamanga ya Java ndi Error 503 yosangalala adziwa kupindulitsa kwake.
• Pali oyikira osiyana: chifukwa Mawindo, Mac OS X, CentOS / RHEL, Fedora, Ubuntu, ndi Servers Application.  
• Mtundu waposachedwa wa 4.02 umabweretsa PostgreSQL 9.3.1, PostGIS 2.1.1, GeoTools 10, GeoServer 2.4.3 ndi GeoWebCache 1.5; ndipo imathandizira OpenLayers 3.
• Muyambidwe loyambirira mndandanda wachindunji umalengedwa kuti uime kapena kuyamba GeoServer ndi Postgres; Komanso kuti muzitha kugwiritsa ntchito mawonekedwe a deta kwa Postgres (shp2psql) komanso kuti mutsegule ku PostGis (PgAdmin).
• Komanso pazosankha zoyambira pali mwayi wopeza localhost, yomwe pamtunduwu imachotsa mawonekedwe amakasitomala 3, ndikuwongolera koyera ku ntchito za GeoServer, GeoWebCache ndi GeoExplorer.
• Chogulitsachi, GeoExplorer ndikutukula kochititsa chidwi kwa ma Boundles kutengera GeExt yomwe imagwira ntchito yowonera deta ya GeoServer, imalola kutsitsa kwa fayilo kuchokera kufayilo yakomweko kapena kuchokera kosungira zinthu, kutha kukhazikitsa utoto, makulidwe amizere, kuwonekera poyera, kulemba, kuphatikiza malamulo ndikusunga molunjika ku fayilo ya kalembedwe ka geoServer (sld). Palibe amene ali ndi malingaliro abwino omwe amagwiritsa ntchito iyi kukhala yoyera ndipo GeoExplorer ndi yankho labwino kwambiri -ngakhale kumachita zinthu zambiri-.

• Mtundu woyikika wa GeoServer umaphatikizanso ulalo wolowetsa deta, kutha kupanga magwero kuchokera pamapangidwe am'deralo, kuphatikiza PostGis yomwe deta imatha kusunthidwa kuchoka pamunsi kupita kwina kuphatikizidwa kuchokera ku Localhost kupita kumalo osungidwa; Ndizosangalatsa kuti kusungidwa kwa dongosololi kumathetsa mavuto a OGR2OGR omwe, pokhapokha atachita ndi mzere wotonthoza, amaponya zovuta mukamakweza maulamuliro angapo, popeza kusakhulupirika ndi polygon yosavuta.
• Pankhaniyi, mautumiki a WPS amawoneka chifukwa mwa njira yoyenera kukhazikitsa ndinaganiza zowaphatikiza.
• Zowonjezera za GeoServer monga CSS Styling, CSW, Cloustering ndi chithandizo cha malaibulale azithunzi a GDAL zitha kuwonjezedwa nthawi yakukhazikitsa. Palinso Zowonjezera za PostGIS zomwe zimathandizira mitambo yazosungika ndipo GDAL / OGR itha kuyikidwanso ngati kasitomala. Kwa opanga pali mwayi wokhazikitsa Webapp SDK ndi GeoScript.
• Mosiyana wanga ndinkakhala nalo pa Baibulo Seva, ndikuona kuti pali magwero zotheka deta kuti inshuwalansi akhoza kuwonjezeredwa Koma ngati amene akubwera ndi OpenGeo Maapatimenti Baibulo kumabweretsa delimited lemba koma H2, H2 JNDI, SQL Server, OGR, Oracle ndi chiwopsezo cha zinthu zomwe zimayambira ku raster.

Nanga bwanji Qgis?

• Zabwino kwambiri, kwa Qgis adapanga pulogalamu yayikulu yotchedwa OpenGeo Explorer yomwe mutha kulumikizana ndi database ya Postgres komanso GeoServer. Kuchokera apa mutha kusintha ma slds, kusuntha zigawo, magulu osanjikiza, kusintha mayina, kufufuta, kuwona malo ogwirira ntchito, zigawo zosungidwa, ndi zina zambiri.
• Ngati wosanjikiza achotsedwa, sld imachotsedwa; zonsezi ndizosinthika ndipo pamapeto pake zimapindula ntchito kuchokera kwa kasitomala akuyang'anira zomwe ziri, kuti kuvomereza kungagwiritse ntchito REST API.
• Pakuti tsopano alibe ndi shp2psql koma n'zosadabwitsa ndiye Integrated mu gulu lomwelo, mwina ngati mandala monga pulogalamu yowonjezera Malovu mosiyana ndi masitolo UI yogwirizana, inu mukhoza kukweza zigawo zingapo kutchinga, patsogolo kapamwamba ndi zambiri zenizeni komanso mauthenga olakwika kwambiri.

Ndi OpenGeo Suite sikunena kuti iyi ndi njira yamatsenga. Koma zithandizadi kuti anthu ambiri ammudzi azichita izi, makamaka popeza makampani omwe amagulitsa maphunziro angasankhe kuphunzitsa njirayi yomwe imatsimikizira kupindika kwakanthawi kochepa.

Kombo ikugwirizana ndi zipangizo zina zomwe zingakwezedwe pa seva.

Zimakhudza bwanji OpenGeo Suite

Tidzawona momwe izi zimakhudzira anthu ammudzi, chifukwa kumbuyo kwa Boundless pali anthu omwe akudziwa zambiri pantchito, omwe akhala akuchita nawo ntchito yopanga zida ndi malo owerengera omwe tsopano akupangitsa kuti ntchitoyi ikhale yolimba. Koma koposa zonse ndimaphunziro azamalonda ndi kutsatsa ntchito, zomwe nthawi zambiri zimawonongedwa pamlingo waluso. Kutchula osachepera asanu ndi limodzi:

• Eddie Pickle ndi Ken Bossung, omwe anayambitsa IONIC, kampani yomwe idagula ERDAS ku 2007 ndipo tsopano ili ndi Leica.

• Andreas Hocevar ndi Bart van den Eijnden, omwe adasindikizidwa mu chitukuko cha OpenLayers 2 ndi GeoExt.

• Victor Olaya, yemwe adatichotsera cholowa cha SEXTANTE,

• Paul Ramsey, wa oyambitsa oyamba a PostGIS.

Zomwe zimakhudza kwambiri ndizofanana ndi kampani yaikulu, kuti kunja kwakhala khunyu pamsika-yomwe nthawi zonse ili pangozi-, imapereka mpikisano wopikisana ndi makampani apadera pazinthu monga chithandizo, kukhulupilika, chitetezo Kuletsa khalidwe pazochitika.

Ntchito zosiyanasiyana zomwe Boundless ali nazo, kuyambira kusamukira papulatifomu kupita kuntchito zothandizira pachaka, zimawoneka ngati zikugwirizana ndi msika wamabizinesi ndi mabungwe omwe pang'ono ndi pang'ono amvetsetsa kusiyana kokhala ndi chithandizo cham'deralo ndi chithandizo chamabizinesi. Msikawu suyenera kukhala wophweka, koma timawona ndi maso abwino momwe mabungwe amakulira m'malingaliro, ndikuyamikira kukula kwa mapulogalamu ndi chidziwitso ngati chinthu chofunikira, motero adatha kusiya kugawa magalimoto amisala kwa oyendetsa magalimoto awo, kukalembera inshuwaransi yapadera ndi ntchito zina a makampani ogulitsa.

Pachitsanzo chotseguka, pali mwayi kwa aliyense. Chifukwa chake zomwe Zopanda malire zilipo, ndi mwayi khalani mnzanu; Kupitilira kuthekera kwa iwo omwe akufuna kukulitsa kuthekera kwawo kugulitsa ntchito potengera kukhazikitsa, kuphunzitsa, kuthandizira kapena chitukuko. Chitsanzo chikuwoneka chofunikira kwa ife komanso cha maphunziro abwino oti tingaphunzire ndikuthandizira kuyesetsa kwa gvSIG Foundation mwanjira ina, yomwe tidzakambirane nthawi ina.
