Kusintha kaganizidwe ka mapu

Tisanaone momwe tingachitire ndi AutoCADMap 3DBwanji ngati tizichita pogwiritsa ntchito Microstation Goegraphics. Samalani, izi sizingachitike ndi AutoCAD yachibadwa, kapena ndi Microstation yokha.

Ntchitoyi imayendetsedwa pogwiritsa ntchito zida / njira yothandizira / kukonza dongosolo. Tsamba ili likuwonekera, zida zomwe ali nazo ndizogwiritsa ntchito georeferenced; Tidzagwiritsa ntchito zitatu zoyambirira zomwe tiyenera kugawa ndikusintha mapu. Chachinai ndikupanga ma gradrant grids ndipo chomaliza ndikubwezeretsa ntchentche.

1. Perekani ziyerekezo.

Kwa ine, ndikufuna kugawa ntchito UTM, yokhala ndi datum WGS84 (NAD83), zone 16 Kumpoto. Kuti muwonetse tsambalo, dinani pachizindikiro choyamba mpaka gululi litayamba, lomwe titha kulikoka kuzitsulo zakumbali:

Timagwiritsa ntchito batani loyamba (kusintha) kuti tiwonetsere, kenako timasankha Standard Projection, Universal Traverse Mercator, yokhala ndi Datum WGS84 ndi mayunitsi m'mamita. Kudzanja lamanja kumasankhidwa, komwe pakadali pano kuli 16 kumpoto kwa dziko lapansi, kuti zosinthazo zigwiritsidwe ntchito batani lachitatu (save master) lasankhidwa.

2. Sankhani ndondomeko yoyenera

Pachizindikirochi chachiwiri chikugwiritsidwa ntchito, kupanikiza mbewa mpaka pulogalamuyi yatsegulidwa:

Poterepa, ndikufuna kusintha mapu anga kukhala olumikizana ndi malo, chifukwa chake ndikusankha batani lachisanu ndi chiwiri, kenako ndikudina batani lachiwiri (reference edit) kuti ndiyisinthe, ndikusankha mulingo woyenera / malo (latitude / longitude), pogwiritsa ntchito wgs84 datum ndi mayunitsi mpaka madigiri. Kenako batani lachinayi, (Reference save) likugwiritsidwa ntchito.

3. Pangani kutembenuka

Izi zachitika ndi zida za batani lachitatu la gulu loyamba.

• Ngati tikufuna kusintha fayilo lonse, timasankha choyamba (kusintha zonse)
• Ngati mukufuna kuchita kokha ndi mpanda, iyenera kukhala yogwira ntchito ndipo njira yachiwiri imasankhidwa (kusintha kwa fence)
• Ngati mukufuna kusintha zinthu zina, sankhani gawo lachitatu (chinthucho chimasintha),
• Zotsatirazi ndi kusintha mafayilo mu mtundu wa ASCII
• Ndipo wotsiriza ndikusintha mafayela ambiri (batch).

Mukasankha chisankho, dinani pazenera.
