Cholakwika chosavuta pomanga meta yokhala ndi mapepala: Gawo lochokera pa mapu
Ndikufuna kudzipereka izi kukhala zolakwika zosavuta kuyeseza, makamaka mu 1: 10,000 ndi 1: mamapu a 1,000 omwe amagwiritsidwa ntchito pazolinga za cadastral omwe adatengedwa kuchokera ku ma 1: 50,000 mesh.
Kumbukirani kuti m'mbuyo pomwe tidawona momwe pangani meta iyi, ndipo poyamba tidawona momwe pitani kuyamba mpaka mukafike pa mapu 1: 1,000. Koma cholakwitsa kwambiri ndikukhulupirira kuti maunawa akhoza kuthyoledwa pamapu, ndipo izi sizolondola. Mgwirizanowu uyenera kupangidwa pogwiritsa ntchito kutalika ndi kutalika nthawi iliyonse yomwe tikufuna kupanga mesh yolimba ndipo ngati sitikuwona zotsatira zake.
Ngati ili ndi gawo la kutalika kwa 6 ° ndi 8 ° latitude, lolingana ndi zone 16, kupanga maulalo a UTM ndikosavuta ndikuwatumizira ku AutoCAD. Tiyerekeze kuti wina wapenga poganiza kuti maunawa akhoza kudulidwa pamapu:
Gawolo, popanda kuwerengetsa ma midpoint, momwe amapendekera kuti atsegule mpaka itafika pakatikati pomwe lingapangitse kusiyana kwa 2,318.63 mita ya latitude.
Mukamapanga gawo lotsatira, cholakwika chofananacho chingapangidwe, koma chimatsitsidwa motere:
1: 1,000 (6 °): osagawa
Gawani 1: 500,000 (3 °): 2,318.63
Gawani 1: 250,000 (1 ° 30´): 579.76
Gawani 1: 100,000 (30´): 129.00
Gawani 1: 50,000 (15´): 16.13
Makhalidwe ali pakati pa magawo ndi omwe amapangidwamo, motero kutengera kuchuluka momwe amagawanikana, zotsirizira zake zimapezedwa, zomwe zimatha kukhala tsoka lathunthu ngati wopanga zojambula wabwino awunikiranso ntchitoyo.
Tikuwonanso kuti ngati titha kugawaniza pepala la 50,000 kuti tichotse ma 10,000 titha kukhala ndi cholakwika pamalo apakati mpaka mita ya 16 kuti pakuwunika kwa cadastral m'tawuni kumakhala kwakukulu komanso koopsa ngati sichili yunifolomu chifukwa chimenecho ndiye cholakwika chapakati .
Ngakhale kugawa kwa 10,000 mtunda ndi wocheperako kotero chizolowezi chakugawana pepalali pamapulogalamu ndizofala kwambiri ... bola mukatha kupewa chingakhale bwino.
Vuto ndikufuna kupanga gululi mumtunda wamtali ndi kutalika momwe tidawonera positiPazosindikiza, koma vuto lalikulu kwambiri ndiloti ndi kudzudzula (monga NAD27 mpaka NAD83) ndi pulogalamu yomwe idapangidwira izi, izi zipanga zolakwika zomwe zingapangitse kuzunzika kwam'mutu.
