Izibikezelo ze-2014 zesimo se-geofumado: Paul Ramsey

Kusukela ngoJanuwari, uPaul Ramsey wadedela ukubikezela kwakhe kulo nyaka ensimini ye geospatial; ikhumbula ukuthi lokhu umuntu oseneminyaka kule ndawo iminyaka engaphezu 10 iminyaka futhi umphumela iminikelo yabo isofthiwe ovulekile etholwe 2008 Sol Katz Award ukhishwa yi OSGeo Foundation, siletha version elihunyushwe.

Eminyakeni eyishumi eyedlule, lapho iPostGIS yayiyinguqulo nje engu-0.8, umhlaba wawusha futhi musha, ngangiqiniseka ngokuphelele ukuthi imboni yethu yayisemaphethelweni wenguquko yomthombo ovulekile. Lapho abantu bezama amathuluzi amasha, aguquguqukayo, amasha wezinhlelo zokwakha, ngokwemvelo balahla isoftware yabo yakudala futhi ngokushesha baqala ukudlulela ekukhanyeni okuthe xaxa. Ngangijabule, ngezwa i-geofumato yalokho okuzayo.

Futhi njalo, cishe njalo ngonyaka kusukela ngo-2000 othile wamemezela, endaweni ethile, ngawo wonke umphefumulo wakhe ukuthi (ekugcineni) "kulo nyaka kuyoba unyaka wedeskithophu ye-Linux".

Okuthile okuxakile kwenzeke endleleni kuguquko lomthombo ovulekile. Kuvele okungaphezu kwalokho. Sekukonke, ushintsho beluhamba kancane, luhamba kancane, kepha luhlala luqondiswa kwamacala wokusebenzisa umthombo ovulekile kakhulu.

Ngakho-ke, ngilindele okungenzeka ngonyaka omusha womhlaba ovulekile womhlaba, ukubikezela kwami ​​kungahle kungabi ukuhlakanipha - izinto ezinkulu zizoshintsha kancane, kodwa emingcele sizoba nezinguquko ezibalulekile:

I-Oracle izomemezela ukuthi balahlekelwa amakhasimende ku-PostgreSQL. Nakuba i-MySQL ihlezi ikumithombo yezindaba “njengesizindalwazi somthombo ovulekile”, kube yi-PostgreSQL enamakhono ebhizinisi kusukela ekuqaleni ukuze ihambisane nezinsizwa ezinkulu. Njengoba i-Oracle iqhubeka nokwenyusa amanani okulungisa ukuze ijabulise i-Wall Street, amakhasimende aseqala ukucabanga ngezinto ezingacabangeki:  mhlawumbe sekuyisikhathi sokuhlola kabusha izinga lakho le-database.

Okupholile kunazo zonke kuzoqhubeka nomthombo ovulekile ezisekelweni Noma ngabe isebenza ku-Linux, amandla we-GDAL anezithombe zesathelayithi ezivela ku-PlanetLabs noma amaphilisi akamuva we-Android, into ebanda kunazo zonke izoba emahlombe omthombo ovulekile kanti okunye kuyinzuzo.

Iningi lomthombo ovulekile lomthombo uzoba ku-JavaScript.  UJuan ukhulume lolo hlelo lwenkambu ye-geospatial luyakhuphuka lubheke kwi-polyglot, kepha inkundla yomthombo ovulekile njengamanje umhlaba weJavaScript, zombili ezingeni leklayenti neseva. Kukhona umsindo omkhulu nokufutheka lapho. Ezinye zazo azisho lutho, kepha ezinye zazo zibeka amazinga esizobe siwasebenzisa eminyakeni eyishumi ezayo. IJavaScript ingikhumbuza nge-Java circa-2005: amaphrojekthi amaningi, anezinhloso ezifanayo zokusebenza, amafilosofi wokuqamba ancintisanayo, kanye namandla amakhulu. Ukwehlukaniswa kwezimpawu zomsindo kulezi zinhlobo zezimo kuholela ekuhlangenwe nakho kwangempela, ngakho-ke ngiyajabula ukuthi sinamaJavaScript amahle kakhulu futhi aqhakazile emhlabeni we-geospatial ethimbeni lethu.

I-PaaS izojoyina umthombo ovulekile ekuziphendukeleni kwemvelo. Futhi njengoba ngivele ngazi ipulatifomu njengensizakalo (PaaS), ngiyabona ukuthi inesithembiso somthombo ovulekile nejika elifanayo lokufunda. Ngenxa yalokho, izinto zizowela ngaphansi kwesisindo sabo, kancane kancane sizohlanganiswa nengqikithi ye-IT, yize thina abanolwazi sizoyithola futhi isizukulwane esilandelayo sizongena emisebenzini yokusebenza. Futhi njengoba iPaaS ingumthombo ovulekile ngokwencazelo, ukukhula efwini nasezingxenyeni zezinhlelo zokwakha kuzohlala futhi kuzothuthukisa umthombo ovulekile.

Ukuthuthukiswa kwesitayela somthombo ovulekile okuphindaphindayo kuzothola indawo eyengeziwe. Ukwehluleka komphakathi kwesiza se-healthcare.gov kanye nenkambiso yendlela yokusebenza kungaba kuhle ekuthuthukisweni okuhle. Akhona kakade amakhono amaningi ezinkampanini, kodwa kuseyinto eyenziwa yizinhlangano "eziqhubekayo" kuphela, akuyona into evamile. Lapho abantu becabanga kakhulu ngobuchwepheshe ngezindlela zomthombo ovulekile (ukuthi inqubo, hhayi umkhiqizo, imayelana nokuphatha ushintsho, ukungafinyeleli esimweni sokuphela), umthombo ovulekile uba ngcono.

Izinhlangano zizokulangazelela ukusebenzisana ne-OpenStreetMap, kanti ezinye zizothola indlela. Ngenkathi amalayisense ezoqhubeka nokukhawulela izinhlangano eziningi zomphakathi ukuthi zibambe iqhaza, ezinye zizokwenza ukuthula futhi ziqale ukuhlanganisa i-OSM ekusebenzeni kwayo. Abanenhlanhla bazothola ukugunyazwa ngabameli babo ukuthi basebenze ne-OSM ngqo. Esimweni esinenhlanhla encane, i-OSM izosetshenziswa njengentambo ejwayelekile yokugcina amamephu evuselelwe… 🙂.

I-Boudlesss izohlanganisa ubuchwepheshe obuningi bokuvula emithonjeni yayo I-OpenGeo Suite, okwenza kube lula nakakhulu ukuqala ngezinhlelo zebhizinisi ze-geospatial. Nokho lokho bekulula kusukela U-Eddie usuvele ukhulume ngakho, kodwa nami nginezizathu zami.
