Importʻikepili mai OpenStreetMap a hiki i QGIS

Ka nui o nā'ikepili i loko OpenStreetMap He laulā maoli nō ia, a inā'a'ole'o ia e ho'onui piha'ia, ma ka hapanui o nā manawa, ua'oi aku ka pololei ma mua o nā'ike i'ike'ia ma o nā 1 pālākiō laulā: 50,000.

I ka QGIS he mea nui ia e hoʻokomo i kēia papahana e like me ka palapala honua Google, kahi e noho nei nā plugins, akā he palapala hoʻohoho kēia wale nō.

Pehea inā makemake'oe i ka papa OpenStreetMap e like me ke ki'i?

1. Hoʻoiho i ka waihona pūnaewele OSM

E hana ai i kēia, pono ʻoe e koho i kahi āu e manaʻo ai e hoʻoiho i ka ʻikepili. ʻIke ia i nā wahi nui loa, kahi e nui ai ka ʻike, nui a nui ka manawa o ka waihona. E hana i kēia, koho:

Vector> OpenStreetMap> Hoʻoiho

Maʻaneʻi e koho ʻoe i ke ala e hoʻoiho ai i ka faila xml me ka extension .osm. Hiki ke kuhikuhi i ka pae quadrant mai kahi papa e kū nei a i ʻole i ka hōʻike o kēia manawa o ka ʻike. Ke koho ʻia ke koho ʻae, Ho'omaka ka polokalamu kelepona a ua hō'ike'ia ka nui o nā'ikepili i ho'ouna'ia.

2. E hana i kahi hōkeo ʻikepili

I ka lawe'ia'ana o ka faila XML, pono ia e ho'ololi i kēia i loko o kahi'ikepili. 

Hana ʻia kēia me: Vector> OpenStreetMap> Ka lawe ʻia mai topology mai XML ...

Maanei, ua noi'ia mākou e komo i ke kumu, ka waihona puka DB DB SpatiaLite a inā makemake mākou e hana koke'ia ka pilina komo'ana.

3. Kāhea i ka papa i QGIS

Kāhea'ia ka'ikepili e like me kahi papa e koi ana:

Vector> OpenStreetMap> Kuhi ʻia i topology i SpatiaLite ...,

Pono e hōʻike ʻia inā e kāhea ana mākou i nā kiko wale nō, nā laina a i ʻole nā ​​polygons. Eia pū me ke pihi hoʻouka mai ka waihona pūnaewele hiki iā ʻoe ke papa inoa i nā mea hoihoi.

Ma muli o kēia hopena, hiki iā mākou ke halihali i ka papa ma ko mākou palapala'āina, e like me ia i hō'ike'ia ma kēia ki'i.

'Oia'i'o, no ka mea he mea wehe kumu'o OSM, e lawe nui'ia nā mea hana pono e hana i kēia'ano mea.
