Izibikezelo ze-2014 zesimo se-geofumed: uPaul Ramsey

Ukuqala ngoJanuwari, uPaul Ramsey ukhuphe ukuqikelela kwakhe kulo nyaka kwicandelo le-geospatial; Ukuthathela ingqalelo ukuba ngumntu obekhona kule ndawo iminyaka engaphezulu kwe-10 kwaye kuthi, ngenxa yegalelo lakhe ukuvula isoftware, wafumana i-Sol Katz Award evela kwi-OSGeo Foundation kwi-2008, siyizisa ngenguqulelo eguqulweyo.

Kwiminyaka elishumi eyadlulayo, xa i-PostGIS yayingaqhelekanga kwinguqulo yayo ye-0.8, umhlaba wawumtsha kwaye umtsha, ndandiqinisekile ukuba imboni yethu yayisisizathu sokuvukela komthombo ovulekileyo. Xa abantu bekwazile ukuzama izixhobo ezintsha, eziguqukayo kunye nezixhobo ezitsha zokwakha iinkqubo kwaye belahla ngokwemvelo isoftware yakhe yobunikazi kwaye ngokukhawuleza baqala ukufudukela kubukho bokukhanya okungakumbi. Ndavuya, ndaziva i-geofumada yento ezayo.

Kwaye ngalo lonke ixesha, phantse yonke iminyaka ukusukela ngonyaka wama-2000 kwabhengezwa umntu, kwindawo ethile, nangawo wonke umphefumlo (ukuba)kulo nyaka iya kuba ngunyaka wedesktop yeLinux«.

Into engaqhelekanga yenzekile apha endleleni kumthombo ovulekileyo. Kwavela ngaphezulu koko. Ngokubanzi, utshintsho luhamba kancinci, kancinci kancinci, nangona luhlala luye kwicala lokuvula iimeko zokuvula umthombo.

Ke, ndilindele into enokwenzeka kunyaka omtsha wehlabathi elivulekileyo lomthombo we-geospatial, uqikelelo lwam lungangabinangqondo - izinto ezinkulu ziya kutshintsha zincinci, kodwa kwimida siya kuba neenguqu ezibalulekileyo:

paul ramseyI-Oracle iya kubhengeza ukuba abathengi bayaphulukana ne-PostgreSQL. Nangona i-MySQL ihlala ikwimithombo yeendaba njengo "vimba wolwazi ovulekileyo", ibiyiPostgreSQL enobuchule bokushishina ukusuka ekuqaleni ukuya kubambiswano kunye neegrisi. Njengoko i-Oracle iqhubeka isonyusa amaxabiso okugcina izinto ukonwabisa i-Wall Street, abathengi baqala ukucinga malunga nokungakholeleki: mhlawumbi lixesha lokuba uvuselele umgangatho wakho wokugcina.

Eyona ndawo ipholileyo iya kuqhubeka nomthombo ovulekileyo kwiziseko. Nokuba yinto esebenzayo kwi-Linux, amandla e-GDAL ngemifanekiso yesatellite ye-PlanetLabs okanye iitafile zamanje ze-Android, eyona nto ipholileyo iya kuba segxalabeni lomthombo ovulekileyo kwaye okuseleyo kuyinzuzo.

Uninzi lwenyathelo lomthombo ovulekileyo liya kuba kwiJavaScript. UJuan ukhankanyiwe ukuba inkqubo yentsimi ye-geospatial yanda ngokuya kwi-polyglot, kodwa umthombo ovulekileyo kwindawo ngoku lilizwe leJavaScript, zombini kwinqanaba labaxumi kunye neseva. Kukho ingxolo enkulu nomsindo apho. Inxalenye yayo ayithethi nto, kodwa enye yoku kukubeka imigangatho esiza kube siyisebenzisa kule minyaka ilishumi izayo. IJavaScript yandikhumbuza ngeJava isangqa-2005: iiprojekthi ezininzi, kunye neenjongo ezifanayo zomsebenzi, ukhuphiswano loyilo lwefilosofi, kunye namandla amakhulu. Ukwahlula imiqondiso yengxolo kwezi ntlobo zeemeko zikhokelela kumava okwenyani, kungoko ndiyavuya ukuba sinayo eminye ebalaseleyo neqaqambe kakhulu yeJavaScript kwi-geospatial world kwiqela lethu.

I-PaaS iya kujoyina umthombo ovulekileyo kwindalo yendalo. Kwaye njengokuba ndiqala ukwazi iqonga njengenkonzo (i-PaaS), ndiye ndabona ukuba inesithembiso somthombo ovulekileyo kunye nejika lokufunda ngokwalo. Ngenxa yoko, izinto ziya kwehla ngokobunzima bazo, ziya kuthi ngokuthe ngcembe zidityaniswe kumbindi we-IT, nangona sinamava siza kuyifikelela kwaye isizukulwana esilandelayo siza kuya emsebenzini wokusebenza. Kwaye ekubeni i-PaaS inguMthombo oVulekileyo ngokwenkcazo, ukukhula kwelifu kunye nezinto zeenkqubo zokwakha ziya kugcinwa kwaye ziya kuphucula umthombo ovulekileyo.

Ukuphuhliswa kwesitayile sokuvula imithombo evulekileyo yokufumana ulwazi iya kufumana umhlaba ongaphezulu. Ukungaphumeleli koluntu kwindawo yezempilo.gov kunye neendlela zokuphelisa indlela zingalungele uphuhliso olufanelekileyo. Sele enobuchule obuninzi kwiinkampani, kodwa iseyinto eyenziwa yimibutho "eqhubayo" kuphela, ayisiyiyo into. Abantu abaninzi ngakumbi bacinga ngetekhnoloji kwifom yomthombo ovulekileyo (eyinkqubo, engeyiyo imveliso, imalunga nolawulo lotshintsho, engafikeleli kwisimo sokugqibela), umthombo olungileyo ovulekileyo uya kubakho.

Imibutho iyakulangazelela ukusebenza ne-OpenStreetMap, kwaye ezinye ziya kufumana indlela. Ngelixa iilayisensi ziya kuqhubeka ukunciphisa umda wemibutho emininzi yoluntu ukuba ithathe inxaxheba, abanye baya kwenza uxolo kwaye baqale ukudibanisa i-OSM ekusebenzeni kwabo. Abanethamsanqa baya kufumana ukuqinisekiswa kwamagqwetha abo ukuze basebenze ngqo ne-OSM. Kwimeko enethamsanqa, i-OSM iya kusetyenziswa njengomtya wokuhambisa ukugcina iimephu zihlaziywa ...….

I-Boudlesss iya kudibanisa iitekhnoloji ezingumthombo ovulekileyo kuyo I-OpenGeo Suite, kwenza kube lula ngakumbi ukuba baqale ngeshishini le-geospatial shishini. Ewe, kwakulula ukusukela U-Eddie sele eyichazile, kodwa nam ndinezizathu zam.
