MUAYYAN KARDANI KOORDINATI NUQTAI DARKORI DAR GLOBUS VA HARITAI GEOGRAFI

Dar globus va kharitai geografi khar yak nuqtaro metavon muayyan kard, ki onro koordinati geografi menomand. Baroi on ki koordinati geografii nuqtai darkoriro muayyan namoem, arz va tuli geografiro boyad donist.

Arzi gsografi. Masofai yagon nuktaero, ki dar sathi Zamin az khati istivo ba samti SHimol va yo Janub bo daraja ifoda yoftaast, arzi geografi menoman. Arzi geografi az khati istivo ba samti SHimol va Janub az 0° to 90(‘ (kutbho) tagyir meyobad.

Binobar in tamomi nuktahoe, ki az khati istivo dar shimol joygirand. ba arzi SHimoly mansuband (a.sh). On nuqtakhoe, ki az khati istivo dar janub voqe gardidaand, ba arzi Janubi (a.ch ) dokhil meshavand. Nuqtahoe, ki dar yak khati muvozi joygirand (khoh az khati istivo dar shimol va khoh dar janubi on) yak khel arzi geografi dorand. Arzi khati muvozy dar globus dar khathoi nisfiruzin 0° va 180°, dar kharitaho boshad, dar hoshiyai onho navishta msshavad.

Baroi muayyan kardani arzi geografii nuqtai darkori (masalan, yagon shahr) pesh az hama arzi khati muvoziro boyad muayyan kard, ki vay dar on jo voqe gardidaast. Ammo nuqtai darkori na hama vaqt bevosita dar arzi khati muvozi voqe gardidaast. Aksar vaqt nuqgai darkori dar bayni du khati muvozi vomekhurad. Dar in surat avval arzi khati muvozii ba khati istivo nazdikro meyobem, ki nuqtai darkori ba on nazdik voqe gardidaast. Sipas ba arzi khati muvozii paydokardaamon miqdori darajai kamonaki khati nisfiruzii (meridian) bayni nuqtahoi darkori va khati muvoziro zam menamoem:

Masalan, shahri Dushaibe az khati istivo dar 30″ arzi shimoli (a.sh.*) voqe gardidaast. Bad miqdori darajai kamonaki khati nisfiruziro az khati muvozi to nuqtai shahri Dushanbe muayyan mekunem. On ba 8| barobar ast. Soni 8″-ro ba 30 jam mekunem, ki hosili on ba 38” barobar meshavad. On arzi geografii Dushanbero muayyan mekunad.

Savol va suporish.

  1. SHabakai geografi chist?
  2. Qutbhoi geografiro nombar kuned.
  3. Hathoi muvozi va meridianro fahmoned.
  4. Arzi geografiro sharh dihed.
  5. Az kharitai tabiii nimkuraho arzi shahri Pekinro muayyan kuned.
  6. Baroi muayyan kardani nuqtai darkori dar globus va kharita chy kor kardan zarur ast?
