Izvo zvirevo zve 2014 zve geofumado mamiriro: Paul Ramsey
Kutanga munaJanuary, Paul Ramsey akatanga utambo hwake hwegore rino mumunda we geospatial; kufungisisa kuti uyu ndiye munhu anenge ari ezvinhu ichi kwemakore anopfuura 10 kwemakore uye mugumisiro zvipo zvavo rakavhurika bhuku Software kugamuchirwa 2008 ari Sol Katz Award paakavapa neDare OSGeo Foundation, isu kuuya akashandurwa Bhaibheri.
Makore gumi apfuura, apo PostGIS yaingova vhezheni 0.8, nyika yaive nyowani uye nyowani, ndaive nechokwadi chose kuti indasitiri yedu yaive pamucheto weakavhurika sosi shanduko. Apo vanhu pavakazoedza izvozvi zvitsva, zvinoshanduka-shanduka, zvishandiso zvitsva zvekuvaka masisitimu, ivo zvakasarudzika vakarasa yavo yechinyakare software yekutengesa uye nekukurumidza vakatanga kutamira muhupenyu hwakajekeswa. Ndakafara, ndakanzwa geofumato reizvo zvaiuya.
Uye nguva dzose, rinenge gore rega rega kubva 2000 mumwe munhu akazivisa, kumwe kunhu, nemweya wavo wese kuti (pakupedzisira) "gore rino richava gore reLuxux desktop".
Chimwe chinhu chinoshamisa chakaitika munzira munzira yakavhurika sosi shanduko. Zvakazoitika kupfuura izvozvo. Pakazara, shanduko yanga ichinonoka, zvishoma nezvishoma, kunyangwe ichigara iri munzira yekuvhurika kwenzvimbo dzekushandisa mashandiro.
Saka, mukutarisira izvo zvinogona kuitika mugore idzva reakavhurika sosi geospatial world, fungidziro yangu inogona kunge isiri yekuchenjera - zvinhu zvikuru zvichachinja zvishomanana, asi mumiganhu tichava nekuchinja kukuru:
Oracle ichazivisa kuti vari kurasikirwa nevatengi kuPostgreSQL. Kunyangwe MySQL inogara iri munhau se "iyo yakavhurika sosi dhatabhesi", yanga iri PostgreSQL yakave nehunyanzvi hwebhizinesi kubva pakutanga kuenda pamwe chete nevakomana vakuru. Sezvo Oracle ichiramba ichikwidza mitengo yekuchengetedza kuti ifadze Wall Street, vatengi vari kutanga kufunga zvisingafungidzike: Zvichida inguva yekudzokorora zvakare nheyo yako yepamusoro.
Iyo inotonhorera ichaenderera yakavhurika sosi mune hwaro. Kunyangwe iri kumhanya paLinux, GDAL kugona nemasaiti satellite kubva kuPlanetLabs kana mapiritsi eazvino eAroid, chinhu chinotonhorera chichava pamapfudzi eakavhurwa sosi uye zvimwe zvese zvinobatsira.
Nyaya yakawanda yechitsauko chekuita ichava muJavaScript. Juan akataura Iko kuronga kweiyo geospatial munda kuri kuwedzera kuenda kune polyglot, asi yakavhurwa sosi nhandare izvozvi ndiyo nyika yeJavaScript, zvese padanho remutengi uye server. Kune ruzha rukuru uye hasha ipapo. Zvimwe zvacho hazvireve chinhu, asi zvimwe zvacho zviri kumisikidza zviyero zvatichange tichishandisa kwemakore gumi anotevera. JavaScript inondiyeuchidza nezve circa-2005 Java: akawanda mapurojekiti, ane zvakafanana zvinoshanda zvinangwa, kukwikwidza dhizaini dhizaini, uye hukuru kugona. Kupatsanurwa kwemasaini eruzha mumhando idzi dzezviitiko kunotungamira kune chaiko chiitiko, saka ndinofara kuti tine mamwe akanakisa uye akajeka maJavaScript mune nyika geospatial kuchikwata chedu.
PaaS inobatana yakavhurwa sosi mune yechisikigo shanduko. Uye sezvo ini ndirikungosvika pakuziva chikuva sevhisi (PaaS), ndinoona kuti ine zvese chivimbiso cheyakavhurwa sosi uye yakafanana yekufunda curve. Nekuda kweizvozvo, zvinhu zvichawira pasi pehuremu hwavo, zvishoma nezvishoma zvichabatanidzwa mukati mekona yeIT, kunyangwe isu vane ruzivo tichazvibata uye chizvarwa chinotevera chichienda mumabasa ekushanda. Uye sezvo PaaS iri Yakavhurika Sosi nedudziro, kukura mugore uye izvo zvikamu zvekuvaka masisitimu zvicharamba zviripo uye yakavhurwa sosi inowedzerwa.
Iterative yakavhurika sosi dhizaini yekuvandudza inowana yakawanda nzvimbo. Kukundikana kweveruzhinji kweiyo healthcare.gov saiti uye mafambiro eiyo nzira anogona kungove akanaka kune budiriro yakanaka. Patova nehunyanzvi hwakawanda mumakambani, asi ichiri chimwe chinhu chinoitwa nemasangano "anofambira mberi" chete, haisi iyo yakajairika. Kunyanya vanhu vanofunga nezve tekinoroji munzira dzakavhurika sosi (kuti inzira, kwete chigadzirwa, ndeye kutonga shanduko, kusasvika kumagumo), iyo iri nani yakavhurika sosi inova.
Masangano anoshuvira kushanda neOpenStreetMap, uye vamwe vanowana nzira. Kunyange marezinesi acharamba achiganhurira masangano mazhinji eruzhinji kutora chikamu, vamwe vanogadzirisa uye vanotanga kubatanidza OSM mukufambiswa kwavo kwebasa. Vane rombo rakanaka vanogashira kutsigirwa kwemagweta avo kuti vashande neOSM zvakananga. Muchiitiko chine rombo shoma, OSM inozoshandiswa seshinda yakajairwa kuchengetedza mepu dziripo… 🙂.
Boudlesss ichabatanidza mamwe magetsi ekuzarura mukati mawo OpenGeo Suite, zvichiita kuti zvive nyore kutangisa nemabhizimusi geospatial masisitimu. Zvakanaka izvo zvaive nyore kubvira Eddie akatozvitaura, asi ini ndinewo zvikonzero zvangu.
