Tengani kafukufuku OpenStreetMap kuti QGIS

Kuchuluka kwa deta mkati OpenStreetMap ndizowonjezera, ndipo ngakhale kuti sizinasinthidwe, nthawi zambiri zimakhala zolondola kwambiri kuposa deta yomwe imakhala ikugwiritsidwa ntchito pogwiritsa ntchito mapepala a 1: 50,000.

Mu QGIS ndizosangalatsa kutsegula zosanjikiza ngati mapu monga maphunzilo a Google Earth, omwe mapulagulu alipo kale, koma iyi ndi mapu okha.

Bwanji ngati mukufuna kukhala otsegula OpenStreetMap ngati vector?

1. Sungani maziko a OSM

Kuti muchite izi, muyenera kusankha malo omwe mukufuna kuyembekezera deta. Zili zoonekeratu kuti madera akuluakulu, pomwe pali zambiri zambiri, kukula kwa databata kudzakhala kwakukulu komanso kozengereza. Kuti muchite izi, sankhani:

Vector> OpenStreetMap> Koperani

osm qgis

Pano mumasankha njira yomwe fayilo ya xml yokhala ndi .osm yowonjezera idzasungidwa. N'zotheka kuwonetsa quadrant kuchokera pazomwe zilipo kapena mwawonetsero wamakono. Mukasankha kusankha kuvomereza, ndondomeko yowunikira imayambira ndipo deta yowonongeka ikuwonetsedwa.

2. Pangani Zotsatira

Pamene fayilo ya XML imasulidwa, iyenera kutembenuza izi kukhala deta.

Izi zatheka ndi: Vector> OpenStreetMap> Thirani chipolopolo kuchokera ku XML ...

osm qgis

Pano tikufunsidwa kuti tilowe mu gwero, DB SpatiaLite pulogalamu yotulutsira ndipo ngati tikufuna kulumikizana kwachinsinsi kutengedwe nthawi yomweyo.

3 Itanani wosanjikiza ku QGIS

Kuitana deta monga wosanjikiza kumafuna:

Vector> OpenStreetMap> Kutumiza Topology ku SpatiaLite ...,

osm qgis

Izi ziyenera kuwonetsedwa ngati titchula mfundo zokha, mizere kapena polygoni. Ndiponso ndi batani ladongosolo la deta mungathe kulemba zomwe ziri zochititsa chidwi.

Zotsatira zake, tikhoza kusungira chingwe pamapu athu, monga momwe tawonetsera pa chithunzichi.

Inde, chifukwa OSM ndi njira yotseguka, idzatengera zambiri zogwiritsira ntchito payekha kuti muchite izi.
