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.

Dab tsi yog qhov txawv ntawm daim ntawv qhia lub hom phiaj thiab daim ntawv qhia lub hom phiaj tshwj xeeb?
Qhov tseem ceeb hauv daim ntawv qhia dav dav yog nyob ntawm qhov chaw. Phab ntsa daim duab qhia chaw, feem ntau daim ntawv qhia pom nyob rau hauv atlases, thiab txoj kev maps yog tag nrho cov nyob rau hauv qeb no. Thematic maps, tseem hu ua daim ntawv qhia tshwj xeeb, qhia txog thaj chaw faib khoom ntawm ib lub ntsiab lus lossis qhov tshwm sim
Daim ntawv qhia lub hom phiaj tshwj xeeb siv rau dab tsi?
Daim duab qhia lub hom phiaj tshwj xeeb yog siv los pab koj tsom mus rau qee cov ntsiab lus. Piv txwv li: Topography, Climate los yog koog tsev kawm ntawv. Daim duab qhia lub hom phiaj tshwj xeeb tuaj yeem pab tau rau kev sim nrhiav qhov chaw, nrhiav ntau ntxiv txog cov pej xeem, kev ncig xyuas, kev nce siab thiab lwm yam
Hom ntaub ntawv twg yog qhov zoo tshaj plaws ntsuas los ntawm Isoline daim ntawv qhia?
Txhais. Tus sawv cev isoline yog txoj kev siv ntau tshaj plaws los pom qhov tshwm sim ntau yam uas tshwm sim thoob plaws thiab qhov muaj txiaj ntsig sib txawv tsis tu ncua hauv qhov chaw. Lawv thiaj li hu ua continua. Piv txwv li continua yog kub, huab cua siab, nag lossis daus heights los yog av elevations
Lub hom phiaj ntawm daim ntawv qhia yog dab tsi?
Daim ntawv qhia yog ib qho piv txwv ntawm kev xaiv cov yam ntxwv ntawm ib qho chaw, feem ntau yog kos rau ntawm qhov chaw tiaj tus. Maps nthuav qhia cov ntaub ntawv hais txog lub ntiaj teb nyob rau hauv ib qho yooj yim, pom kev. Lawv qhia txog lub ntiaj teb los ntawm kev qhia qhov loj me thiab cov duab ntawm lub teb chaws, qhov chaw ntawm cov yam ntxwv, thiab qhov deb ntawm qhov chaw
Hom kev sib raug zoo li cas yog qhia hauv daim phiaj xwm tawg?
Lub scatterplot yog siv los sawv cev rau kev sib raug zoo ntawm ob qhov sib txawv. Muaj ob hom kev sib raug zoo: zoo thiab tsis zoo. Cov kev hloov pauv uas muaj kev cuam tshuam zoo txav mus rau tib qho kev taw qhia, thaum cov hloov pauv uas tsis zoo cuam tshuam txav mus rau qhov sib txawv
