Lokho abafundi abakucabangayo nge-Open Source Geospatial

Le ndatshana isuselwe kuphrezentheshini eyanikezwa kwa-FOSS4G e-Barcelona ngoSepthemba 2010 ngu:

U-Iraklis Karampourniotis no-Ioannis Paraschakis – base-Aristotle University of Thessaloniki
Zoi Arvanitidou – waseNyuvesi yase-Aegean

Isixhumanisi sidluliselwe kimi UGabriel Reyes, futhi kusekelwe embuzweni othi, uma i-Open Source Software ingacatshangelwa njalo ezifundweni zendawo ye-geospatial yomsebenzi wasenyuvesi noma ekunikezweni kwezifundo zamahhala zabathweswe iziqu kanye nomphakathi jikelele.

Ekugcineni impendulo inguyebo, nakuba endleleni kunezinto ezimbalwa okufanele kusetshenzwe kuzo ekushumayeleni ivangeli kwabafundi abavame ukukhombisa ukumelana nokuphatha kahle ithuluzi elingelona uphawu oludumile, njenge-ESRI, AutoDesk noma i-Intergraph; ngenxa yomcabango wokuthi ngeke kubavulele amathuba amaningi emakethe yezemisebenzi.

Kuphinde kungifikele lokho GIS ezininginingi naphezu kokuba isofthiwe "ilapho” kushiwo kwezinye zesoftware yokuphathelene njengokuthi I-AutoCAD Imephu ye-3D, ArcGIS y Geomedia; izixazululo ezinezinga lokuduma nokugunyazwa komkhiqizo okufanele zifunwe kakhulu yilabo abathanda isifundo se-Geographic Information Systems. Ezingeni lezinkampani ezizimele ezihlinzeka ngezinsizakalo zokuqeqesha, ukuhlehliswa kwalo mgoqo bekuhamba kancane, nokho isikhungo semfundo ephakeme singadlala indima ebalulekile uma izinzuzo zesofthiwe yamahhala enazo njengamanje mayelana nokuvuthwa kanye nokwamukelwa kwezokuphatha zicatshangelwa umphakathi. noma umkhakha webhizinisi, ngaphandle kwalokho okusho ukunciphisa igebe lokungabi semthethweni kanye nokwehlisa izindleko.

Umzamo wokuqala wehlulekile

Ababukisi basho ukuthi babe nesandulela ngo-2006, lapho befaka i-GRAS kumalebhu kanye ne-AutoCAD Map kanye ne-ArcGIS. Ngaleso sikhathi umphumela wawuwukuthi abasebenzisi babengakuthandi nhlobo ukuxhumana okungenabungane. GRASS, futhi kuyaqondakala ukuthi ukuxuba into eyodwa nenye akulethi ngaso sonke isikhathi imiphumela emihle, futhi akuboni njengethuluzi elizimele esimweni lapho ukuhambisana kuyingxenye yezitayela ezihamba phambili ezihamba phambili endaweni yomthombo ovulekile.

Lapho sibonisa uhla olugcwele lwamathuluzi okuthuthukiswa, ukwakhiwa kwedatha, ukuphatha, ukuhlaziywa kwe-vector/raster, nokushicilela, siyaqaphela ukuthi nakuba imizamo ye-OSGeo yayingazalelwanga ekuvumelaniseni, manje singaqinisekisa ukuthi imizamo yokumisa nokusimama bathole ukulingana okufanele. ukuqondanisa okunokulinganisela, okuqondiswe kundwangu yekhwalithi.

Igrafu engenhla enikeziwe nguJorge Sanz noMiguel Montesinos kuNkomfa Yokuqala ye-gvSIG e-Latin America uzama ukucacisa nokuhlukanisa ngokwezinga elivundlile ukuthi ayini amathuluzi agxile kwideskithophu, ngombala oluhlaza imitapo yolwazi kanye nokumpunga okunye okunamandla okusebenza kuseva. Ngombala onsomi abaphathi besizindalwazi kanye nezinga eliqondile izilimi.

Lokhu kubuka konke kwe-OSGeo ecosystem kusisiza siqonde ubudlelwano phakathi kwamaphrojekthi kanye, ngaphezu kwakho konke, ukuqonda ukuthi ukuhlukahluka kuyadingeka futhi kuyasebenza inqobo nje uma amazinga esamisiwe.

Umzamo wesibili, uphumelele

Izikhulumi ziphawule ngokuthi emzamweni wesibili bahlukanise izifundo phakathi kwabafundi asebephothulile noma abasemazingeni aphansi. Ukwenza lokhu, basebenzise izifundo ngendlela ehambisanayo:

QGis + GRASS + PostGIS ezifundweni zabathweswe iziqu

QGIS + PostGIS kuma-laboratories abenza iziqu

Lawa afanayo ngiwaphawule ngokubomvu emfanekisweni wangaphambilini, ukukhombisa lapho atholakala khona, ngokuyisisekelo endaweni ye-C++ exhunywe ekushicilelweni kwe-inthanethi kwe-MapGuide Open Source noma i-MapServer.

Ithebula elilandelayo libonisa izihloko ezafakwa ezifundweni nasezilabhorethri.

Ithebula elilandelayo libonisa umbono wabantu ekupheleni kwezifundo, okutholakele okuthakazelisayo okungase:futhi kufanele ngokusebenzisa imifelandawonye- ihlelwe ngokuningiliziwe, isabalalisa amathuluzi afana nezikhathi zokuqeqesha ezijwayelekile, imibhalo yemethodiyo, amabhange izinto, amazinga okusebenza kanye namamanyuwali, ukuze angashintshwa amanyuvesi noma amakolishi obuchwepheshe; ngokuvamile izixazululo zobunikazi zalokhu zabelana ngamamanyuwali kuphela. Ngalokhu, kungaba usizo kakhulu ukwenza izifundo ezimfushane noma ama-diploma aphelele anikeza ubukhulu obugcwele endaweni ye-OSGeo kokubili kulayini we-C++ kanye nemvelo ye-Java, enamandla kakhulu (ngombono wami) ngenxa yobubanzi bayo be-multiplatform. , ukuhwebelana kwamazwe ngamazwe okuhlelekile kanye nokuhlukahluka kwezixazululo.

Njengoba kungabonwa, imibandela yochwepheshe abathweswe iziqu igxile kahle emandleni amathuluzi, esikhundleni semikhiqizo esheshayo abayikhiqizayo. Lokhu kudinga ukusabalalisa, uma sithemba ukudala isiko lokuthembana kanye nokwethembeka isixhumanisi phakathi kwesikole nezinhlangano ezithuthukisa i-OSGeo nezinkampani ezihlinzeka ngamasevisi ahlobene.

Bona isethulo sokuqala
