I-KML ... i-OGC ifomethi noma i-monopoly format?

Izindaba zikhona, futhi yize bekungaphezu konyaka owedlule ukuthi ifomethi ye-kml ibithathwa njengejwayelekile ... mzuzu lapho yamukelwa khona igxeka kakhulu ngezinhloso zeGoogle zokulawula ifomethi ebekeke kahle kakhulu. Lokho manje kuthiwa i-kml ikumazinga we-OGC, kuvezwe imibono eyehlukene.

Into enhle

Izindinganiso zihle, ukube bezingekho, ukusebenzisana phakathi kwamathuluzi ahlukahlukene obuchwepheshe, ikakhulukazi awokuhweba, bekungeke kusimame. Into ye- Vula i-Gis Consortium (I-OGC) ukuhlela amazinga omhlaba wendawo avumela ukudalwa kwezinqubo zokushintshanisa ngaphansi kwezikimu ezibhalwe phansi, njengezincazelo zezinhlangano, ubudlelwane kanye nezichazamazwi zedatha njll.

Uma sibheka uhlu lobuchwepheshe imikhiqizo yabo eminingana enabo ngaphansi kwesiqubulo esithi "izindinganiso ze-ogc" sibona ukuthi umzamo usekelwe kahle kakhulu, kuhlanganise ne-AutoDesk, ESRI, Bentley, Intergraph, Leica, Oracle, CadCorp, Mapinfo, Manifold. .phakathi kokunye.abanye bahlanganisa iMicrosoft ngonyaka odlule. Leli thebula libonisa izigaba okukhona kuzo amazinga e-OGC, okuhlanganisa i-KML, okungaba izinga ledatha ye-XML geolocation.

Kuze kube manje kuye kwaba nzima ukuba basebenzisane KML ngaphandle kokuthi uyangenisa (KML DXF), kanye nosuku-Google akubanga ukunxanela uyonika ikhono lakho Google Earth eyodwa ngqo evulekile .shp noma .dxf; iqiniso lokuthi KML ejwayelekile ungase ucabange ukuthi lezi zinto angashintsha ngoba kuqinisekisa ukuthi ukuziphendukela kwemvelo ningeke niyilalele uyahlanya kuphumelele nenqubo ezihilelekile-Google futhi lokusungula embonini geospatial kanye nomphakathi jikelele.

Ngakho-ke akukubi, ukuthi i-Google ikhulula ifomethi yayo ye-kml futhi kuhle ukuthi yenza kanjalo ngaphansi kwemodeli "evulekile", ngoba ngale ndlela ukusimama kungaqinisekiswa kulabo abafaka imali ekuthuthukisweni. Lokhu kusho ukuthi kube lula ukudala izinhlelo zokusebenza ngaphandle kokungenisa noma ukuguqula idatha, futhi nakuba kubonakala sengathi kunengqondo kakhulu, umbandela "ovulekile", ngaphandle kokubambisana, ufuna ukungathathi hlangothi, ukuzuza wonke umuntu ngaphandle kokubhalisa amafomethi ngohlelo oluthile... ngaphandle Google, kunjalo..

Okubi

Inkinga yukuthi lokhu kuvunywa kwefomethi yi-OGC kuza esikhathini esibucayi emakethe amakhulu ezobuchwepheshe; futhi sibheke ngokuqondile ngesikhathi lapho I-Microsoft ayikwazanga ukuthenga Yahoo! ngubani ozimisele ukudlala ngothando no-Google.

I-Microsoft ihlula i-Google kumathuluzi edeskithophu, i-Google yehlula wonke umuntu ophethe i-inthanethi, i-Yahoo! ishaya kokubili ekukhangisweni kwe-inthanethi. I-Microsoft ibheja ngamalayisense abathunjiweyo, i-Google izama ukukhuthaza ukusetshenziswa "kwezinhlelo zayo" zamahhala, i-Yahoo! liyafa njalo ngomzuzwana. I-Virtual Earth ikhona nsuku zonke okukhangayo nakakhulu, IGoogle Earth isemboze okuningi, amamephu we-Yahoo ...

Lokhu kuhlangana okuncane yikho okuvusa ukungabaza uma iGoogle izama ukudedela i-kml emphakathini, hhayi ngoba inika okuthile emhlabeni kepha ngoba ifuna wonke umuntu asebenze ngefomethi esivele ikwazile ukuyibeka ... efanayo lapho iMicrosoft inikela .NET kunoma ngubani ofuna thuthukisa izinhlelo zokusebenza zedeskithophu, uqinisekise ukuhambisana nesitayela sokuholela emazingeni amakhulu okuhlupheka nokufuna ukumboza iJava. Futhi, ingxenye enkulu yomphakathi we-geospatial ibukele phansi amandla we-kml ngenxa yamandla ayo alinganiselwe, ngoba yize sivuma ukuthi iGoogle Earth neGoogle Maps banezimpumelelo ezinhle, i-kml ayenzi lutho olunye ngaphandle kokubonisa izindawo zokuthwebula, ngoba umgomo konke: ukulula kwendawo ngaphezu kwe-xml futhi njalo kugxilwa kuwebhu. Kepha ukuthuthuka kwamathuluzi amakhulu wedeskithophu akuthintanga ngaphezu kokungenisa nokuthumela i-kml ngenxa yalowo mkhuba osile weGoogle wokusibethela i-API yabo kunoma iyiphi indawo.

... futhi lokhu kungadedela ithuba lokuthuthukisa intuthuko elixhuma kudatha ye-Google Amamephu ngaphandle kokuya nge-API yayo? Kuze kube manje, uma ufuna ukwenza okuthile kufanele uthole isikhulu se-Google, mtshele ukuthi ufuna ukwenzani, yini ofuna ukukukhombisa, idatha izobukeka kanjani ... bese ulindela ukunikezwa imibandela yezinga lesinqumo esiphezulu ongalibonisa kufanele ubeke uphawu lwe-Google futhi, isibopho sokuthenga iKlayenti le-Google Earth Enterprise ngentengo abangacabanga ngayo noma esimweni esithe xaxa faka I-Google Earth Pro kwi-server ehlelwe yinto yakhe.

Nakuba sishaya indiza ngokuthi enye indlela evulekile isekelwa ubuchwepheshe obuhle kahle, njenge-Google nezinkulungwane zezizinda abaye zazithuthukisa ku-API yabo, sikhumbula ukuthi kungekudala ukuthi i-MySQL, eyathola ukusebenzisana okukhulu emphakathini, Usuku lathengwa nge-SUN ngenani elincane kakhulu amaRandi ayizigidi ezintathu. Futhi yalabo abasize ukuxazulula izimbungulu zenguqulo ngayinye ababonanga nepeni.

Engqungqutheleni yaseBaltimore, sengiyakwazi ukuyicabanga inkulumo kaMark Reichardt, oyi-CEO ye-OGC ozonikeza i-plenary ebizwa ngokuthi: “Umbono we-OGC“, nalapho bazonikela khona i-altare ku-Google. Izophelelaphi le noveli?
