Momwe mungakhazikitsire ma quadrants pamapu a cadastral

Poyamba tinayankhula Kusiyanitsa pakati pa UTM ndi maofesi a dziko, muzotsatila izi tidzalongosola momwe tingakhalire mapu a quadrant pamakani akulu a ntchito ya cadastre.

Pankhani kulenga mapu nusu Kuphunzira, geographers amafanana kuti ndi ntchito ya milungu pamene cartoonists mukukhulupirira izo kutsanzira chabe gululi kuti amakhala Orthogonal.

Chiyambi cha gridi iyi ndikugawana kwa dziko lapansi ndi meridians ndi zofananira.Samalani, muyenera kusankha spheroid yowunikira, chifukwa izi zimatanthauzira kukula kwa magawowo. Ndikugwiritsa ntchito chitsanzo cha Honduras, kuti ndimvetsetse.

mapu ndi Buku lonse, malingana ndi makina amenewa masamba 24 "x36" choncho pamene tigwiritsa ntchito sikelo tidzakhala kunena za chiŵerengero izi sipangakhalenso munkakhala mapu, pogwiritsa ntchito gawo ake yopingasa kunena za 24 "x36" kuphatikizapo malo pepala masamba.

Honduras ili pakati pa madera 16 ndi 17, ndipo gawo P lopangidwa ndi kufanana, malo omwe amadziwika ndi lalanje ali ndi madigiri asanu ndi limodzi pakati pa kufanana. Mukasindikiza mapu amderali, sikelo ndi 1: 1,000,000

Zitha kuwoneka bwino kwambiri kuti dera lalanje ili limachokera ku 84W kupita ku 90W meridian ndipo pakati pa 8N ndi 16N ndiye gawo la madigiri 6 kutalika ndi madigiri 8 kutalitali. Komanso ku sintha mawonedwe Kwa UTM umalongosola kuti ukhoza kuona angles.

Pogawa gawo ili kukhala magawo anayi tiri ndi zigawo 4 za 3 ° ndi 4 °, kusindikiza kwa mapuwa kuli pafupi ndi 1: 500,000; Izi zikhoza kumasulidwa mu vector format (kml, shp, dxf, dgn) m'malo osiyanasiyana kuchokera kulumikizana uku.

Tikagawa gawoli nthawi ziwiri, aliyense wa iwo adzakhala 1 ° 30 'm'litali ndi 1 ° pamtunda. Mapu awa adasindikizidwa pa 1: 250,000.

Ndiye ngati amodzi mwa zigawozi agawika magawo atatu opingasa komanso awiri ofukula tidzakhala ndi madera a 30 'longitude ndi 30' latitude, awa amasindikizidwa pamlingo wa 1: 100,000.

Ndiye ngati tigawa gawo limodzi mwa zigawozi kukhala magawo awiri opingasa ndi atatu ofukula, tidzakhala ndi madera a 15' longitude ndi 10' latitude ndipo awa ndi mapu odziwika bwino monga "mapepala a zojambula" 1:50,000.

Ndiye ngati tikufuna kutenga mapu a kafukufuku wa kumidzi 1: 10,000 ndizokwanira kuti tigawani zigawo izi 5 ziwalo zowoneka bwino za 3 'ndi 2' za latitude; Kufotokozera kuti malinga ndi momwe timapezera, zingagawidwe mu 4 x 4, chifukwa pamene imachoka ku equator ndi yopapatiza.

Kuti mapu 1: 5,000 zigawo kuti 1'30 "ndi 1, chifukwa mapu 1: 2,000 36 zigawo" ndi 24 "ndi mapu 1: 1,000 izo zikanakhala kugawanitsa m'zigawo za 18" wautali 12 "ufuluwo.

Ngati tiyang'ana, palibe imodzi yomwe imafuna kuzungulira, chifukwa ngodya zikhoza kuwerengedwera m'madera ozungulira ndi kutembenuzidwa kupita ku UTM kuti muwatenge pamapu. Kutembenuza maofesi a dziko kupita ku UTM pali mapulogalamu.

Chofunikira ndikuyamba papepala la 1: 50,000 lomwe limadziwika bwino ndikuwerengera ma UTM kenako ndikupanga kugawa ku AtoCAD. Chitsanzo chowonetsedwa ndi Honduras, ndimapepala ake 1: 50,000 mu gridi yayikulu ndi 1: 10,000 mu gridi yaying'ono.

Pa nomenclature? ... adzakhala tsiku lina.

Mu gawo lina, zochitika zofananazi zachitika, ndizochitikira kumwera kwa dziko lapansi, makamaka ndi Bolivia.
