Kuyerekeza ndi kusiyana pakati pa QGIS ndi ArcGIS

Anzanu a GISGeography.com apanga nkhani yamtengo wapatali imene amafanizira GQIS ndi ArcGIS, mosasamala kanthu pa nkhani za 27.

Zikuonekeratu kuti miyoyo ya nsanja onse ndi yaikulu, poganizira kuti QGIS chiyambi pachibwenzi ku 2002, monga anasiya atsopano khola buku la ArcView 3x ... kuti kale m'gulu ulendo zokwanira.

Mosakayikira, sitinawonepo kukula ndi chidwi cha nkhani ya Geospatial ngati yomwe ogwiritsa ntchito mayankho awiriwa adakumana nayo. Kumbali imodzi, ESRI yothandizidwa ndi kutsetsereka kwachinsinsi kwa kampani yomwe yakhala ndi zaka zopitilira 40 pamsika, ndi mwayi wokhala sing'anga yomwe idabwera kudzawonetsera masomphenya apadera kuchokera kutsatsa komanso malingaliro osadziwika a anthu; pomwe QGIS ndi gawo lokhalitsa kwambiri mu njira ya GIS, yomwe idakwanitsa kugwiritsa ntchito kuthekera konse kwachitsanzo cha OpenSource, kukonza gulu lomwe silitsogoleredwa ndi odzipereka okha komanso akatswiri ambiri.

Kawirikawiri, kuyerekezera kumatipatsa kuwala kochititsa chidwi mu zinthu monga:

• 1. QGIS ili ndi njira yotsegulira mtundu uliwonse wa deta.
• 2. Onsewa amafunafuna njira yosavuta yosanjikiza kwa ogwiritsa ntchito kumapeto, ngakhale ndi QGIS sikophweka ngati tiona kuti kulemera ndi mapulagini.
• 3. Kufufuza kwa deta pakati pa QGIS Browser ndi ArcCatalog ndikosangalatsa, koma amalephera malinga ngati atengera kukhalapo kwa metadata. Nthawi zonse kumakhala kovuta kusanthula ma data.
• 4. Magulu olowa nawo amagwiranso ntchito onse awiri, ndi zabwino zochepa za QGSIS.
• 5. Kubwezeretsanso ndikusintha dongosolo loyang'anira. Zonsezi ndizovomerezeka kuthana ndi ziwonetsero zakomweko komanso ntchentche, ngakhale phindu lake lakhala kuti QGIS idakwanitsa kuwerenga ziwonetsero kuchokera pa fayilo ya .PRJ popanda zolakwika.
• 6. Zida zambiri zapaintaneti mu ArcGIS Online ndizovuta kwa QGIS kuti ndi pulogalamu ya OpenLayers imalola zigawo zambiri zakumbuyo koma palibenso zina zambiri.
• 7. Geoprocessing ndiyabwino kuposa QGIS, koma osati chifukwa ArcMap ilibe, koma chifukwa zimadalira mtundu wa layisensi yomwe ilipo, kuti ntchito zosiyanasiyana zitha kugwiritsidwa ntchito. Zachidziwikire, pakati pazida zambiri ndizotheka kutayika tisanayese zonse, ngati tilingalira njira zonse zomwe GRASS ndi SAGA ali nazo, zomwe tikadafuna kale kukhala ndi chida chimodzi.
• Zachidziwikire, izi ndi zomwe sizikugwirizana ndi kuthekera kwa pulogalamuyo koma ndi mtundu wa bizinesi. Popeza QGIS ili ndi chilolezo cha GPL, chilichonse chilipo.
• 8. Dziko la mapulagini ndilotakata pamapulatifomu onse awiri. Ngakhale QGIS ndiyotakata kwambiri pamenepa, pomwe pali mapulagini pafupifupi chilichonse, chovuta ndichakuti ArcGIS Marektplace imapangitsa kukhala kosavuta, popeza pali njira zothetsera chilichonse chosavuta kupeza mosavuta. Zachidziwikire, muyenera kulipira.
• Ngakhale kuti AGIS ndi makina olimba kwambiri a geoprocessing machine, ilibe zipangizo zosiyanasiyana za ESRI.
• 9. kasamalidwe ka Raster data kupitilizidwa ndi ArcGIS. Ngakhale QGIS + GRASS imapereka nkhondo, nthawi zonse pamakhala china chake ArcGIS chimakupangitsani kukhala kosavuta; ngati sichoncho ndi zina zowonjezera, chifukwa chovuta kusagwirizana kwa mapulagini okhudzana ndi mitundu yaposachedwa.
• 10. Zida za ArcGIS Geostatistics sizingafanane. Sangogwira ntchito kokha, komanso maphunziro.
• 11. Ndi deta ya LiDAR, muyenera kulingalira, chifukwa pomwe ena amati ArcGIS yadutsa, ena amati ESRI ikuganiza zokakamiza mtundu wake wakutali.

Ndikulingalira kuti ndikuwone ndikuwonjezerani kusonkhanitsa kwanu, chifukwa nkhaniyi yoposa kuteteza chida (chomwe chingakhale chowonekera kwambiri), chikufanizira kufanana kwa 27 mu zinthu monga:

• Network Analysis
• Ntchito Yogulitsa Ntchito (Wowonongeka Zitsanzo)
• Zojambula zomaliza zojambula zithunzi
• Chizindikiro
• Zisonyezo ndi malemba
• Kusintha kwa mapu opitirira
• Kuyenda 3D
• Mapu otchuka
• Makhalidwe
• Zolemba Zapamwamba
• Topological cleaning
• Kusintha deta yamasamba
• XY imagwirizanitsa ndi Kulemba
• Kusintha kwa mitundu ya geometry
• Zolemba zothandizira

Mwachidule, ndi ntchito yolimba yomwe yatsogolera nkhaniyi. Mwanjira zambiri zimafunikira kuzama kwambiri, komwe kumadziwika kokha ndi iwo omwe agwiritsa ntchito ntchito zonse za ArcGIS komanso matumbo a mapulagini a QGIS. Komabe, china chake ndichokhutiritsa:

Sitinawonepo nkhondo ya Epic ku GIS mapulogalamu monga momwe ife tikuwonera.

Kuti muwerenge nkhani yonse, onani chingwe.

Mwa njira, ndikukuuzani kuti muyang'anire akauntiyo @GisGeography, kuti tifunika kuwonjezera Top40 Geospatial Twitter.
