Mercator projection . Mercator projection , hom daim ntawv qhia projection qhia hauv 1569 los ntawm Gerardus Mercator . Nws yog feem ntau piav raws li ib tug cylindrical qhov projection , tab sis nws yuav tsum tau muab los ntawm lej.

Yog li ntawd, 4 hom phiaj xwm phiaj xwm yog dab tsi?

Cov pab pawg ntawm cov phiaj xwm phiaj xwm no tuaj yeem faib ua peb hom: Gnomonic projection, Stereographic projection thiab Orthographic projection

  • Gnomonic projection. Gnomonic projection muaj nws keeb kwm ntawm lub teeb nyob rau hauv nruab nrab ntawm lub ntiaj teb no.
  • Stereographic projection.
  • Orthographic projection.

Tsis tas li ntawd, 3 hom phiaj xwm phiaj xwm yog dab tsi? Peb ntawm cov no hom phiaj xwm phiaj xwm yog cylindrical, conic, thiab azimuthal.

Tsis tas li ntawd, Mercator daim duab qhia qhov project qhia qhov tseeb yog dab tsi?

Raws li tag nrho daim duab projections , cov duab los yog qhov ntau thiab tsawg yog distortions ntawm qhov tseeb layout ntawm lub ntiaj teb nto. Cov Mercator projection exaggerates thaj chaw deb ntawm qhov equator. Piv txwv li: Greenland zoo ib yam li teb chaws Africa, thaum qhov tseeb Africa cheeb tsam yog 14 npaug ntau dua.

Koj yuav ua li cas Mercator projection map?

1st, Kos ib khub ntawm txoj kab ncaj nraim sib tshuam ib leeg ntawm txoj cai kaum. Cov kab no yuav sawv cev rau txoj kab nruab nrab thiab nruab nrab Meridian. Tom ntej no rau qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib npaug raws li kev xam pom hauv kab lus ntawm kauj ruam - 5.
