'O Quantum GIS, ka'ike mua

Inā nā hoaaloha o GvSIG Ua mālama lākou i kā lākou'ōlelo, Pōʻakahi aʻe Iulai 27 e loaʻa iā mākou ka mana 1.9 paʻa. Ma kēia manawa ua maikaʻi ka hoʻāʻo ʻana, e like me ka nui i ʻike ʻia ma ka Ka papa inoa ma ka papa inoa. ʻOiai ua hōʻea ka Pōʻakahi, i ka manawa lana koʻu manaʻo e loaʻa ka ʻoluʻolu o ka hoʻomaikaʻi ʻana i ka huaʻōlelo hoʻokō, ma ka lilo o ka hiamoe ʻole o ka mea hoʻomohala e lawe ai, e nānā iā Quantum GIS e like me kēia mai ka maka manu.

Ua hoʻomohala ʻia ʻo QGIS ma C ++ me ka hoʻohana ʻana i ka toolkit Qt, holo ia ma Windows, Mac a me Linux. Ua ala ka papahana i ka Mei 2002, me ke kākoʻo no 26 mau ʻōlelo a me kāna laikini ʻo GPL.

E ho'ā'o mākou i ka version 1.02 e komo ana i loko o'u i ka maopopo i ka ho'ohana'ana i mea pono hana ho'ohana, hiki iā'oe ke ki'i Mai kēia loulou aʻo ia ka 'O Qgis.

'O ka Quantum GIS hi'ohi'ona

ʻO ke kiʻi kiʻi a me ka hoʻolālā ʻōnaehana ka mea hiki ke kūʻai hou ʻia, ʻaʻole ia e pili i ka hoʻohana ʻana, akā pili i ka ʻono a ke hui (kūʻai aku) ke hāʻawi aku Helehelena kēlā Ua hoʻopiʻi muaʻia o GVSIG, no ka mea, ma kekahi manawa uaʻikeʻia kona kino a me ka halaʻole o ka hana hoʻohālike i kahi mana e haʻi mai iaʻu "Ke nānā aku nei ia i kahi papahana kālaiʻike, uaʻikeʻia kekahi mau kiʻi me ka 8 bitmap paintbrush".

Akā i kēia haʻaheo, Ke hele neiʻo QGIS me ka maʻalahi, hiki iāʻoe ke koho ma waena o 3 i nāʻano likeʻole o kaʻikepili iʻike maikaʻiʻia, me ka hele waleʻana i ka mouse e ke kumu eʻike i ka nānāʻana o ke kiko.

ʻO Quantum GIS mau mea hoihoi

Koi ʻo QGIS i ka mauʻu no nā hana he nui i hoʻokumu pono ʻia i kēlā meahana, maikaʻi loa no ka hana ʻole ʻana i nā hana. Ke hoʻomaka nei ʻo QGIS a loaʻa ʻole ke kau ʻia, hoʻāla ia i kahi alahele; i kēia hihia ke hana nei wau i kahi loiloi me ka ʻole o ka Grass. Ke makemake wau e hoʻouka i kahi waihona o ka mauʻu, no ka mea ʻaʻole i hoʻokomo ʻia ua pani wau i ka noi, no laila ʻaʻole wau e paipai e hoʻohana me ka ʻole o ke kau ʻana i nā mea hana ʻelua.

Pākuʻi, Nui nā kauoha i loaʻa i kahi leka i hāʻawi ʻia, e like me ka hiki ke hoʻouka i ka hana ma ke kaomi wale ʻana i kēia leka. He kūpono loa kēia, hoʻomanaʻo wau i loko o AutoCAD ʻo ia kekahi o nā mahele maikaʻi loa ke hana ʻia nā kauoha āpau ma o ka keyboard.

ʻO ka nānā, ma ka ʻaoʻao hema kahi palapala ʻāina e hōʻike ana i kahi o ka hoʻoili ʻana, me ka hoʻopili ʻana i nā ala ʻelua. Maikaʻi loa, hiki iā ʻoe ke koho i nā papa āu e makemake ai e ʻike i ka nānā ākea, a hiki iā ia ke hoʻokuʻu ʻia ma ke ʻano he aniani lana i kahi nui ʻokoʻa.

ʻO ke kiʻi ʻaoʻao, maikaʻi wale nō, hiki iā ʻoe ke kauō i nā plugins ma ke ʻano he lepili i mua, hiki ke hana ʻia i lana, a me kahi pihi ʻākau maʻalahi e hoʻoiho a hoʻopau paha. Maʻalahi nō hoʻi ka hoʻomalu ākea e kauō ʻaʻole wale ma ka paneli hema akā i ka mea haʻahaʻa hoʻi.

ʻO ka papa lalo, ke hōʻike nei i ka papa ʻaina, ʻikea ia ma kahi, akā hiki ke lana pū kekahi. Hana nui, me nā koho hoʻokele i nā lālani i wae ʻia a hoʻololi i ka laulā kolamu me kahi kauō maʻalahi o kaʻiole. Eia nō hoʻi i ke kiʻina haʻahaʻa he mau hana no ka ʻimi a me ke koho ʻana, e like me ka hana a Manifold GIS, ma kahi o ka pae kūlana maʻalahi.

I ka ho okumu ana o kēia mau 'manao hana ia oi usable, aha iframe o ka pono, ka nani a iaʻu Microstation, like i loko o ka hihia, e ke ua kauohaʻia ka puka aniani kailaʻae me ka hoohuoi ana nā hana.

'Ike'ikepiliUa ka hoʻokumu paʻaʻana o ka geoprocessing a me ka noiʻi i kekahi i koi, ma mua kilohi loaʻa nō kekahi mau mea hoihoi 'hiʻona i makemake e ike i kekahi manawa, e like me fTools plugins nā'āina hōʻikeʻia nani, hydrological a me na mea e ae.

Nā hōʻiliʻili houE like me nā noi gpl, loaʻa kāna waiwai i nā plugins a ke kaiāulu e hana nei ma kahi liʻiliʻi (ʻoiai me ka pōmaikaʻi o ka ʻole ma Java), ma ka paʻamau lawe ʻia mai nā kumu a ʻano liʻiliʻi lākou akā ʻaʻole maʻalahi e like me ka mea i ʻike ʻia: hiki iā lākou ke hoʻouka Pākuʻi WFS, lawe aku i MapServer, hopu i kahi hoʻonohonoho, hoʻohui i nā kōkua i ka ʻike e like me ke kūkulu ʻākau, ka pālākiō a me ke kuleana kope, ka palena o ka huaʻōlelo i palena ʻia e nā koma, he dxf e shp converter, plugin to georeferensi kiʻi, gps console, python console, coordinate mesh , etc. Akā ʻo ka mea ʻoi loa ke koho e hoʻouka i nā plugins Grass he kumuhana kaʻawale. E like me ka mea e hana ʻia me gvSIG a me Sextante ʻoiai mahalo ʻia ke oʻo o ka mauʻu, kekahi o nā pono hana GIS kahiko loa.

Interestingly OGR mīkini hoʻololi, i hiki ke hoʻolilo i mau papa ma waena o kekahi mau kūmole, e like me SHP, DGN, GPX, GML, csv, KML, MapInfo a me BD makahiki Via ODBC, MySQL, PostgreSQL, iwaena o na mea e ae.

'O ka mea maika'i loa: dxf ka miki a kml to dxf, ka papahana akā'a'ole i hana'ia e nā papahana uku'ē a'e.

Nā Hana KaupapaE like me nā pono hana ʻē aʻe, hiki iā ʻoe ke hana i nā lepe ākea, nā hui o nā papa, loaʻa ka palena iki a me ka palena o ka palena o ka zoom, maʻalahi o ka hoʻohui ʻana i nā ʻōnaehana hoʻonohonoho a me ka wānana; i nā papa shp, inā he prj lākou, hoʻopakele ʻo Qgis i kēia ʻike. ʻO nā hana he nui e pili ana i kahi pae holomua, a mākou e manaʻo nei he maikaʻi loa.

He mea hoihoi loa ia pehea e hoʻonohonoho ai i nā ʻano o nā mea, no ka mea, ma ka paneli like aia nā kapu no nā waiwai laulā, symbology, metadata, lepili, hana a me nā ʻano tabula; hiki i nā mea āpau ke mālama ʻia ma ke ʻano he .qml a hoʻouka ʻia e hoʻopili i nā papa ʻē aʻe. Ke lana nei nō hoʻi kēia pākaukau a hiki ke hoʻoponopono i kona laulā a me kona kiʻekiʻe i ka ʻono. ʻOiai ʻo kēia panela a me nā mea ʻē aʻe hiki ke wehe ʻia ma ke ʻano he noi kaʻawale.

Ho'omaopopo i ka mana'o i nā hi'ohi'ona i'ike'ia i ka ma'alahi akā na'e he waiwai nui ka mea, e like me ke ana o nā mamao mamao, i'ike'ia i loko o kahi papa'aha, kahi e komo ai ka mamao o kēlā me kēia me kēia.

Loa'a a ho'oponopono hou

Hiki iā ʻoe ke hoʻouka i ka ʻikepili vector shp, gml, Mapinfo a me ddf, ʻoiai e hiki ke hoʻololi ʻia i ka ʻikepili mai nā ʻano ʻē aʻe ma o ka mea hoʻololi OGR. Hoʻohui ʻia nā papa vector ma o WFS a me PostGIS. Hoʻōla ʻia, ʻae iā ʻoe e wehewehe i ka hoʻopili ʻana o ke ʻano ke hoʻouka ʻana i ka papa.

'O nā pae laulā, kāko'o i kahi kūlana weliweli, ma waho o WMS. Eia hou,'o ka heluhelu'ana i nā kūlana o'OGC WFS, WCS, CAT, SFS, a me GML.

E hana i nā papa vector hou hiki iā lākou ke hana ma o nā faila OGR a i ʻole ka mauu. Mālama ʻia nā papahana e like me XML me kahi hoʻolōʻihi qgs, kahi i mālama ʻia ai ka ʻōnaehana gvSIG.

E pili ana i ka hoʻoponopono ʻikepili, nā kikoʻī e like me ka ʻōnaehana hoʻonohonoho, nā anakahi, ka palena kikoʻī, ka hoʻoponopono ʻana i ka topological, ka ʻae a me ka palena o nā polygons i hoʻopili ʻia i ka papa like a me nā ʻano paʻi (ʻano a ke ahonui) no kēlā me kēia papa i loaʻa i ka papahana. Hoihoi ka hope, ʻoiai ua hoʻohoka wau i ka loaʻa ʻana o kahi ʻāpana a me ke koho vertex wale nō. Koi aku au, he kumu pono ka mauʻu no kēia.

Ua ho'ā'o wau e ho'oponopono i kahi papa, e ho'okomo i kahi lauoho, akā ua'ike au ua lohi loa, ma waho o ka mea e pono ai e hele i ka ho'ohui i nā koho o ka'oki'ana (E kala no koʻu mau pīhoihoi,ʻo ka manawa mua wau e pāʻani ai i kēia mea pāʻani). E ʻike au iā ia ma hope o ka hoʻouka ʻana i nā pono hana hoʻoponopono Grass. ʻAʻole paha he ala inā e hoʻoponopono ana kekahi i kahi papa i ka manawa like, ʻo ka mea e mālama mua i ka lanakila. ugh!

Hō'ike'ike'ike

No nā kumu puka wikiwiki, aia kahi koho e mālama i ka ʻike ma ke ʻano he kiʻi, a me kahi plugin no ka paʻi wikiwiki ʻana, akā ʻokoʻa ka gvSIG, ʻaʻohe ona mana hoʻonohonoho hoʻonohonoho ArcView-style; akā he mea haku mele i manaʻo ʻia iaʻu ua lawe iki ʻia mai ka lauoho, ʻoiai e ʻae ana e hoʻouka i nā datarrames, nā lepili, nā pahu a me nā hōʻailona, ​​a hiki ke hana ʻia i kekahi mau mele no kahi papahana, ʻaʻole i loaʻa iaʻu kahi e mālama ai iā lākou ma ke ʻano he template; 'ōlelo ka puke e hiki ke hiki. Kuhi au aia kekahi mau mea ʻoi aku ka maikaʻi ma nā plugins mauu no kēia mau kumu.

Kuhi a Quantum gis a me ArcGIS

ʻOiaʻiʻo, Ma hope o ke ao hou.
