Tsitsani galimoto ya UTM ya 1: mapepala a 50,000 ochokera ku dziko lanu

Mapepala a 1: 50,000 amadziwika bwino muzojambula m'mayiko ambiri, koyambirira adamangidwa ndi Datum NAD27 yaku America. Poterepa ndawapanga mu WGS84; Sikulakwa kukhulupirira kuti atha kusintha zosintha pakungosuntha vekitala monga anthu ena ankachitira kumadera ang'onoang'ono.

Ngati mukukumbukira, ndisanakweze madera, tsopano ndakweza madera omwewo koma ndi gridi ya 1: 50 mapepala, kumveketsa bwino kuti amatchedwa mapepala a 000: 1 chifukwa ichi ndi gawo lomwe limagwiritsidwa ntchito m'mayiko ena kusindikiza. Komabe, dzina loyenera lajambulali lingakhale mapepala 50,000'1” ndi 30′.

Mapepalawa amapangidwa kuchokera ku geographic coordinates ndipo ndi 1'30” kutalika ndi 1' latitude, zomwe zimawapanga kukhala zigawo zowongoka zomwe zimamanga zipilala zomwe zimatseka kuchokera ku equator pamene akuyandikira mtengo; izi zikutanthauza kuti mkati mwa zone mulibe vekitala imodzi ya izi yomwe ili ndi ngodya yofanana.

Ichi ndi chifukwa chake masambawa ayenera kumangidwa kuchokera ku maiko, tiyeni tione chitsanzo ichi:

Pogwiritsa ntchito fomu pa mapeto pomwe m'dera 14 pa chakumwera kwa Mexico pafupifupi 26,696 mamita yaitali kumapeto chomwecho, koma pa Atlantic miyeso gombe mamita 26,171, monga amatseka pa M'madera a zitunda apamwamba.

Chaka changa chomaliza chinali chofunikira kupanga madera angapo kuti athe kufotokoza momwe amagwirira ntchito pamasamba amapu. Chifukwa chake, ndimayenera kutembenukira kuzomwe ndinali nazo panthawiyo; ndipo ndi njira amachita bwino kwambiri:

Momwe mungapangire galasi

Kugwiritsira ntchito GIS Yowonongeka kumachitika muzinyendo ziwiri zokha:

1. Pangani chisanji chatsopano

Lembani / kulenga / kujambula

Kenako timagawira zowonera, dinani kumanja pa "zojambula", "gawitsani projekiti", ndikusankha UTM, zone 16, North.

2. Pangani mesh

Onani / Graticle

Ndimasankha gululi wa zone 16, yomwe imachokera ku longitude 84 mpaka 90, ndikuyisiya molakwika chifukwa ndi kumadzulo kwa Greenwich. Kufikira latitudo, kuchokera ku equator komanso popeza sindikufuna kuti ifike pamtengo, ndimasankha ziro mpaka 72. Kumanja ndimagawa nthawi iliyonse ndikafuna mauna, omwe ndi gawo la masamba 1: 50,000, izi zimandiyeza 1 '30" ya longitude ndi 1' ya latitude: kulemba 1'30" ndimagawa 1.5 ndi 60 omwe angakhale madigiri 0.25 ndi 1/60 omwe angakhale madigiri 0.166667.

Zimandipatsanso mwayi wosankha ngati ndikufuna maonekedwe (matayala), mfundo, mitanda ... Ndikusankha mizere

Kenako dinani batani "Pangani" ndi "Chabwino"

Kupanga madera ena ndi nkhani yosintha malingaliro awo. Madera a UTM atasinthidwa kukhala Google Earth, umu ndi momwe amawonekera (kubisala zone 16 yomwe ndiyomwe ndidapanga koyambirira).

Kumeneko mukhoza kuona zimenezo:

• Mexico ili m'malo 11, 12, 13, 14, 15 ndi 16. Onse akumpoto kwa hemisphere.
• Guatemala ndi El Salvador m'madera a 15 ndi 16
• Honduras, Nicaragua ndi Costa Rica m'madera a 16 ndi 17,
• Panama m'zigawo za 17 ndi 18
• Colombia ku 17, 18 ndi 19 madera, ndi vuto lomwe liri kumpoto kwa dziko lapansi ndi kum'mwera kwa dziko lapansi,
• Peru mu 17, 18 ndi 19 madera,
• Bolivia mu 19, 20 ndi 21 madera,
• Argentina mu 18, 19, 20 ndi 21 madera,
• Chili m'zigawo za 18 ndi 19
• Brazil m'madera a 18 mpaka 25 kum'mwera kwa dziko lapansi ndi 19 ku 22 kumpoto kwa dziko lapansi,
• Venezuela mu 18, 19, 20 ndi 21
• Uruguay ku madera a 21 ndi 22,
• Paraguay m'madera a 20 ndi 21,
• Ecuador m'madera a 17 ndi 18.

Izi zikuwonetsa malo a UTM omwe ali ndi galasi lofanana la Europa, kuchokera ku chigawo cha 27 kupita ku chigawo cha 37; onse kumpoto kwa dziko lapansi.

Ngati mulibe GIS Manifold, apa mungathe kukopera fayilo ya kmz, yomwe mungatsegule ndi Google Earth:

Sakanizani

Ngati mukufuna kukhala ndi madera onse, mu ulalo wotsatira mutha kugula fayilo yomwe ili ndi zigawo zonse za UTM. Kuphatikizapo madera:
