Sinthani madigiri/mphindi/masekondi kukhala madigiri a decimal

Iyi ndi ntchito yofala kwambiri m'munda wa GIS/CAD; chida chomwe chimakupatsani mwayi wosinthira magawo a malo kuchokera pamutu wamutu (digiri, miniti, yachiwiri) kupita ku decimals (latitude, longitude).

Chitsanzo:  8° 58′ 15.6” W  zomwe zimafuna kusinthidwa kukhala mtundu wa decimal:  -8.971 ° kuti mugwiritse ntchito pamapulogalamu monga Google Earth ndi ArcGIS.

Chithunzi chotsatira chikuwonetsa ma 8 ogwirizanitsa:

Deta ikufanana ndi polygon yotsatirayi, yomwe tagwiritsa ntchito dala pomwe equator imakumana ndi Greenwich meridian. E longitude amatanthauza kuti ali kum’mawa kwa Grewich Meridian, ndipo W longitude ali kumadzulo. N latitudes amatanthauza kuti ali kumpoto kwa equator, ndipo S latitudes ndi kummwera.

Kutembenuzidwa kukhala madigiri a decimal, ngati tingafune ndi nambala ya mfundozo zingakhale ngati gawo loyamba, ndipo popanda nambala ya mfundo kuti mulowetse ku Google Earth zingakhale ngati gawo lachiwiri:

Momwe template imagwirira ntchito kuti isinthe magawo a malo, madigiri kukhala ma decimals pogwiritsa ntchito Excel

Chithunzi chotsatira chikuwonetsa momwe tebulo la kutembenuka lotchedwa ZC-046 limagwirira ntchito.

• Mizati yachikasu ndi yolowetsa deta, kuphatikizapo nambala yozindikiritsa mfundo.
• Kumanja kwa data ya longitude ndi latitude mutha kuwona kutembenuka mu mawonekedwe a decimal, popanda kuzungulira, ndi chizindikiro chake choyipa ngati kuli koyenera.
• Mzere wa lalanje uli ndi deta yosinthidwa, ndi nambala ya mfundo, chigawo ndi longitude.
• Pamutu wagawoli, mutha kuyika kuchuluka kwa malo omwe tikuyembekeza kuti kulumikizana kutha. Samalani, chifukwa kuchepetsedwa kwa magawo a malo kungayambitse zolakwika zazikulu.
• Mzere wa buluu umasonyeza deta yomweyi, koma popanda nambala ya mfundo, monga momwe zingakhudzire fayilo yamtundu wa latitude, longitude (lat,lon) mawonekedwe.
• Kuphatikiza apo, tebuloli lili ndi malangizo ogwiritsira ntchito, mu Chingerezi ndi Chisipanishi.

Momwe mungatumizire ma coordinates ku Google Earth

Kuti muwatumize ku fayilo ya txt, muyenera kungotsegula fayilo yatsopano ndi notepad, kukopera deta kuchokera pamtambo wabuluu ndikuyiyika, ndikuwonjezera mzere ndi malemba lat,lon.

Fayiloyi imatha kutsitsidwa kuchokera ku Google Earth ndi fayilo / kulowetsa. Izi zimathandizira mawu amtundu uliwonse ndi kuwonjezera kwa txt.

Momwe mungatsitse template ya Excel

Mu sitolo yathu mutha kugula template ndi Paypal kapena khadi la ngongole.

Ndilophiphiritsira ngati wina akuwona momwe ntchitoyo ikugwiritsire ntchito komanso kumasuka kwake.

Komanso, mu maphunziro athu a AulaGEO Academy mutha kuphunzira kupanga izi ndi ma template ena mu Maphunziro aukadaulo a Excel-CAD-GIS. Likupezeka mu Spanish o mu Chingerezi
