Hoʻohālikelike a me nā ʻokoʻa ma waena o QGIS a me ArcGIS

Ua hana nā hoaaloha o GISGeography.com i kahi mea koʻikoʻi koʻikoʻi loa i hoʻohālikeʻia me GQIS me ArcGIS, ma lalo o nā kumu 27.

Ua maopopo ka ola o nā papahanaʻelua, no ka mea, e hoʻi ana ka pilina o QGIS i ka 2002, i ka wā wale nō i puka mai ai ka hua hoʻomalu paʻa o ArcView 3x ... ua komo i ka heleʻana.

Me ke kanalua ʻole, ʻaʻole mākou i ʻike e ʻike i ke oʻo a me ka pulakaumaka o ka pilikia Geospatial e like me ka mea i ʻike ʻia e nā mea hoʻohana o kēia mau ʻano ʻelua. Ma kekahi ʻaoʻao, ua kākoʻo ʻo ESRI e kahi ala pilikino o kahi ʻoihana me 40 mau makahiki i ka mākeke, me ke ʻano he medium i hele mai e hoʻolaha i ka ʻike spatial mai kahi mākeke a me ka ʻike lehulehu ʻole loea. ʻoiai ʻo QGIS ka hana kuikawa ma waena o ke ala GIS, i hoʻohana pono ʻia i nā mana āpau o ka hiʻohiʻona OpenSource, hoʻonohonoho i kahi kaiāulu e alakaʻi ʻia e nā mea manawaleʻa wale nō akā ma kahi pae ʻoihana kiʻekiʻe.

Ma ke'ano ma'amau, hiki i ka ho'ohālikelike ke hā'awi iā mākou i nā'ike maika'i i nā'ano like:

• 1. Loaʻa kahi QGIS i kahi ala e wehe ai i kekahi ʻano o ka ʻikepili.
• 2. ʻimi ʻelua i ka maʻalahi o ka papa hōʻike no ka mea hoʻohana hope, ʻoiai me QGIS ʻaʻole maʻalahi ia inā mākou e noʻonoʻo ʻo ka momona ka plugins.
• 3. ʻO ka ʻimi ʻikepili ma waena o QGIS Browser a me ArcCatalog he mea hoihoi ia, akā hāʻule lākou i ka wā e pili ana i ka noho ʻana o metadata. He paʻakikī mau ka ʻimi ʻana ma o ka ʻikepili.
• 4. Hana ʻia nā pākaukau hoʻohui i nā mea ʻelua, me nā pōmaikaʻi QGSIS liʻiliʻi.
• 5. E hōʻole a hoʻololi i ka ʻōnaehana hoʻohui. ʻAe ʻelua i ka lawelawe ʻana i ka wānana ʻōiwi a ma ka lele, ʻoiai ka loaʻa o ka QGIS i ka hopena i heluhelu i kahi wānana mai kahi faila .PRJ me ka ʻole o nā hemahema.
• 6. ʻO ka arsenal nui o ka ʻikepili pūnaewele ma ArcGIS Online kahi pilikia e kali nei no QGIS me ka OpenLayers plugin e ʻae i nā papa o ka hope akā ʻaʻohe mea ʻē aʻe.
• 7. ʻOi aku ka maikaʻi o Geoprocessing ma mua o QGIS, akā ʻaʻole ma muli o ka loaʻa ʻole o ArcMap iā ia, akā no ka mea pili ia i ke ʻano o ka laikini i loaʻa, i hiki ai ke hoʻohana i nā hana like ʻole. ʻOiaʻiʻo, i waena o nā pono hana he nui hiki ke nalowale ma mua o ka hoʻāʻo ʻana iā lākou āpau, inā mākou e noʻonoʻo i nā hana geoprocessing āpau i loaʻa iā GRASS a me SAGA, kahi a mākou e makemake ai e loaʻa i kahi pahu hoʻokahi.
• ʻOiaʻiʻo, he kūlana kēia i pili ʻole me ka hiki i ka polokalamu akā me ka hoʻohālikelike ʻoihana. ʻOiai ʻo QGIS ka laikini GPL, loaʻa nā mea āpau.
• 8. ākea ka honua o nā plugina ma nā pae ʻelua. ʻOiai ākea loa ʻo QGIS i kēia, kahi i loaʻa ai nā plugins no nā mea āpau āpau, ʻo ka mea paʻakikī ka mea e maʻalahi ai ʻo ArcGIS Marektplace, ʻoiai aia nā hāʻina no nā mea āpau me kahi ala loea i maʻalahi e ʻike. ʻOiaʻiʻo, pono ʻoe e uku.
• 'Oiai'o AGIS he mīkini'oihana pa'a honua,'a'ole i loa'a i nā lakohana ESRI'oihana.
• 9. Ua ʻoi aku ka nui o ka mālama ʻana i ka ʻikepili Raster e ArcGIS. ʻOiai ʻo QGIS + GRASS e hāʻawi i kahi kaua, aia kekahi mea ArcGIS i maʻalahi iā ʻoe; inā ʻaʻole ma nā waiwai i hoʻohui ʻia, e ka paʻakikī o ka launa o nā plugina e pili ana i nā mana hou.
• 10. ʻAʻole hiki ke hoʻohālikelike i nā pono hana ʻo ArcGIS Geostatistics. ʻAʻole wale lākou e hana, akā hoʻonaʻauao.
• 11. Me ka ʻikepili LiDAR, pono e noʻonoʻo kekahi, no ka mea ʻoiai e manaʻo ana kekahi ua hala ʻo ArcGIS i ka moana, ʻōlelo kekahi poʻe e noʻonoʻo ana ʻo ESRI i ka hoʻokumu ʻana i kāna ʻano ʻike mamao loa.

Ke hāpai nei au iā'oe e hā'awi aku i kahi nānā a ho'ohui i kāu koina, no ka mea,'o ka mea i makemake'ole e pale i kahi mea hana ('o ia ka mea'oi loa), e ho'ohālikelike'ia nā'ano like'ole 27 i nā'ano like:

• Ka'enehana Networks
• Ka 'Oihana Hana (Ho'olālā Hana)
• Nā huahana kāma'a hope
• symbology
• Nā Ho'olaha a me nā lepili
• Ke 'aikini o nā palapala' āina ma'amau
• 3D Ho'olaula
• Maps Maps
• 'O Thematic
• Hulina Kūlana
• topological, i ka hoʻomaʻemaʻe
• Ho'oponopono'ana i nā'Ikepili Wahi
• XY Coordinates a Coding
• Ho'ololi o nā'ano geometry
• Kāko'o Pūnaewele

ʻO ka mea hope loa he hana nui i alakaʻi i kēia ʻatikala. I nā ʻano he nui he pono ka hohonu hou aku, i ʻike wale ʻia e ka poʻe i hoʻohana i nā hana ArcGIS āpau a me nā ʻōpū o nā plugina QGIS. Eia naʻe, ʻoluʻolu kekahi mea:

'A'ole mākou i'ike mua aku i kahi kaua epic i loko o ka polokalamu GIS e like me ka mea a mākou e'ike nei.

No ka heluhelu'ana i ka paukū piha, E nānā i ka loulou.

Ma ke ala, ke hāpai nei au iā'oe e ho'opa'a i kāu mo'okāki @Nawaiwaiwai, A mākou e makemake ai e ho'ohui i ka Top40 Geospatial Twitter.
