Mercator projection, hom phiaj xwm phiaj xwm qhia hauv 1569 los ntawm Gerardus Mercator Gerardus Mercator Mercator yog ib tus pioneers ntawm cartography thiab tau dav suav hais tias yog tus tseem ceeb tshaj plaws ntawm Netherlandish lub tsev kawm ntawv ntawm cartography nyob rau hauv nws lub hnub nyoog golden (kwv yees li 1570s-1670s.). Nyob rau hauv nws tus kheej hnub, nws yog ib tug tseem ceeb ua lub ntiaj teb thiab cov cuab yeej tshawb fawb. https://en.wikipedia.org › wiki › Gerardus_Mercator

. … Qhov kev kwv yees no dav dav siv rau cov kab kos kev taw qhia, vim tias ib txoj kab ncaj nraim ntawm Mercator qhov projection daim ntawv qhia yog ib txoj kab ntawm qhov tseeb qhov tseeb uas ua rau tus navigator los npaj txoj kab ncaj nraim.
Vim li cas Mercator projection siv?
Hauv xyoo 1569, Mercator tau luam tawm nws daim ntawv qhia ntiaj teb epic. Daim duab qhia no, nrog nws qhov kev kwv yees Mercator, yog tsim los pab cov neeg tsav nkoj taug kev thoob plaws ntiaj teb. Lawv tuaj yeem siv cov kab latitude thiab longitude los npaj txoj kev ncaj. Mercator qhov kev kwv yees tau tso tawm lub ntiaj teb raws li qhov sib txawv ntawm lub tog raj kheej.
Cov cuab yeej ntawm daim duab qhia dab tsi ua rau Mercator qhov projection cuam tshuam?
Txawm hais tias qhov ntsuas kab sib npaug sib npaug ntawm txhua qhov kev taw qhia ib puag ncig, yog li khaws cov kaum sab xis thiab cov duab ntawm cov khoom me me, Mercator qhov projection distorts qhov loj ntawm cov khoom raws li qhov latitude nce los ntawm kab zauv mus rau cov ncej, qhov twg qhov ntsuas ua tsis kawg.
Mercator projection ua haujlwm li cas?
Yuav kom cov kab longitude ncaj thiab tswj lub 90 ° lub kaum sab xis ntawm kab latitude thiab longitude, Mercator projection siv qhov sib txawv ntawm cov kab latitude deb ntawm txoj kab nruab nrab. Yog li ntawd, lub ntiaj teb tus ncej thiab thaj av uas nyob ze tshaj plaws tau hloov pauv.
Qhov zoo thiab qhov tsis zoo ntawm Mercator daim duab qhia qhov projection yog dab tsi?
Qhov zoo: Daim phiaj qhia Mercator qhia cov duab ntawm cov teb chaws thiab cov lus qhia kom raug. Qhov tsis zoo: Daim phiaj qhia Mercator tsis qhia qhov kev ncua deb lossis qhov loj ntawm cov teb chaws, tshwj xeeb tshaj yog nyob ze rau sab qaum teb thiab sab qab teb ncej.
Pom zoo:
Azimuthal equidistant projection ua haujlwm li cas?
Lub azimuthal equidistant projection yog ib daim ntawv qhia azimuthal projection. Nws muajcov khoom siv tau zoo uas txhua lub ntsiab lus ntawm daim ntawv qhia yog nyob ntawm qhov sib npaug ntawm qhov chaw nyob ntawm qhov chaw nruab nrab, thiab txhua cov ntsiab lus ntawm daim ntawv qhia yog nyob ntawm qhov tseeb azimuth (kev taw qhia) los ntawm qhov chaw nruab nrab.
Puas pilots siv conic projection?
Pilots siv aeronautical chartsraws li LCC vim tias txoj kab ncaj nraim kos rau ntawm Lambert conformal conic projection kwv yees ib txoj hauv kev zoo-lub voj voog nruab nrab ntawm qhov kawg rau qhov kev sib tw dav hlau. … Lub Ntiaj Teb Spatial Framework rau Is Nrias teb siv Datum WGS84 nrog LCC qhov projection thiab yog tus qauv NNRMS pom zoo.
Vim li cas ho siv mercator projection?
Mercator projection, hom phiaj xwm phiaj xwm qhia hauv 1569 los ntawm Gerardus Mercator. … Qhov kev kwv yees no tau siv dav rau cov kab kos kev taw qhia, vim tias ib txoj kab ncaj nraim ntawm Mercator qhov projection daim ntawv qhia yog ib txoj kab ntawm qhov tseeb qhov tseeb uas ua rau tus neeg taug kev tuaj yeem npaj txoj kab ncaj nraim.
Formula rau mercator projection?
Tus qauv rau Mercator's projection is T(ϕ, θ)=(θ, ln(|sec(ϕ) + tan(ϕ)|)). Txoj kev ntawm Mercator projection yog dab tsi? Thiab, tus Mercator qhov projection yog tsim kom tso cai rhumb kab kos rau ntawm qhov projection kom yog kab ncaj.
Qhov kev ncua deb ntawm daim ntawv qhia mercator puas yog?
Yog li ntawd, los ntawm kev tsim kho, Mercator qhov projection yog zoo meej, k=1, raws txoj kab nruab nrab thiab tsis muaj lwm qhov. Ntawm lub latitude ntawm ± 25 ° tus nqi ntawm sec φ yog hais txog 1.1 thiab yog li qhov projection yuav pom tau tias yog nyob rau hauv 10% nyob rau hauv ib tug strip ntawm dav 50 ° nyob rau hauv lub equator.
