Nzira yekugadzira quadrants yemadasita mapepa

Pakupedzisira isu takataura pane musiyano pakati peUTM nehutano hwehuwandu hwemashoko, munyaya iyi tichatsanangura kuti tingagadzira sei makadhi emadhora pamakero makuru ekushandiswa kwe cadastre.

Kana totaura asika quadrant nhau mepu, geographers akafanana kuti ibasa vanamwari apo cartoonists tenda zviri chete kutevedzera grid kazhinji anoumba Orthogonal.

Kwakatangira iyi gridhi ndiko kupatsanura kwepasi ne meridians uye zvakafanana, chenjera, iwe unofanirwa kusarudza rezve spheroid, sezvo izvi zvichitsanangura kukura kwezvikamu. Ndiri kuzoshandisa muenzaniso weHonduras, nechinangwa chekuinzwisisa.

The mepu dziri Munongedzo scale, zvichienderana kudhinda izvi kazhinji anobva 24 "x36" saka kana tinoshandisa chikero tose kureva reshiyo ichi chinogona raitenda mepu, uchishandisa ayo chinjikira divi kuchaita kureva kuti 24 "x36" kusanganisira dzezvimwe papepa varikumahombekombe.

Honduras iri pakati pezvikamu gumi nematanhatu negumi nenomwe, uye chikamu P chakaumbwa neakafanana, iyo nzvimbo yakaratidzirwa muorenji ine madhigirii matanhatu pakati pezvakafanana. Kana uchidhinda mepu yenzvimbo ino, chiyero chiri 16: 17

Inogona kuonwa chaizvo kuti ino orenji zone inoenda kubva ku84W kuenda ku90W meridian uye pakati pe8N ne16N saka chikamu chemadhigirii matanhatu pakureba uye madhigirii masere. Zvakare ku shandura maonero KuUTM unoronga iwe unogona kuona mairi.

By kupatsanura nzvimbo iyi migove mina vane 4 3 ° zvikamu nokuda 4 °, kudhinda mepu idzi anosvika 1: 500,000; Izvi zvinogona kubudiswa muvector format (kml, shp, dxf, dgn) kune nzvimbo dzakasiyana kubva pano.

Kana chidimbu ichocho chakakamurwa kuita maviri akareba, imwe neimwe ichave 1 ° 30 'muhurefu uye 1 ° munzvimbo. Mamepu aya aizodhindwa pa1: 250,000.

Zvino kana imwe yenzvimbo idzi yakakamurwa kuita zvikamu zvitatu zvakatwasuka uye zvikamu zviviri zvakamira, tichava nenzvimbo dze 'longitude uye makumi matatu' nematanhatu, idzi dzinogona kudhindwa pachiyero chinofungidzirwa che30: 30.

Zvino kana tikapatsanura imwe yenzvimbo idzi kuita zvikamu zviviri zvakachinjika uye zvitatu zvakadzika, tichava nenzvimbo dze15' longitude uye 10' latitude uye aya ndiwo mamepu anozivikanwa kwazvo se "cartographic sheets" 1:50,000.

Zvadaro kana tichida kutora mamapu ekuongorora kwekumaruwa 1: 10,000 zvakakwana kuti isu tiparadzanise zvikamu izvi 5 chikamu chema 3 'chekureba ne 2' ye latitude; kujekesa kuti maererano nehuwandu hwatinowana, hunogona kugoverwa mu 4 x 4, nokuti sezvo ichienda kure neEquator iri kuderedza.

Kuti tiwane mepu 1: 5,000 zvikamu kuti 1'30 "by 1 ', nokuti mepu 1: 2,000 36 muzvikamu" by 24 "uye nokuda mepu 1: 1,000 zvingadai ive zvikamu 18" pakureba 12 "Latitude.

Kana tikatarisa, hapana chimwe chazvo chinoda kukomberedza, nokuti makona anogona kuverengwa mumiganhu yenharaunda uye akatendeukira kuUTM kuti avatanidze pamepu. Kuti uchinje geographic coordinates kuenda kuUTM kune zvibvumirano.

Izvo zvakanaka ndezve kutanga ne1: 50,000 jira rinozivikanwa uye kuverenga iyo UTM zvinongedzo wozoita chikamu muAtoCAD. Muenzaniso wakaratidzirwa ndiHonduras, nemashizha ayo 1: 50,000 mugidhi hombe uye 1: 10,000 mugidhi diki.

Kubva pamasitlanti? ... ichava rimwe zuva.

Mune iyi imwe nzvimbo basa rakafanana rinoitwa, pamwe nechekuchamhembe kwenyika, kunyanya neBolivia.
