Goode tus homolosine daim ntawv qhia qhov projection yog tsim los txo qis distortion rau tag nrho lub ntiaj teb no. Nws yog ib qho cuam tshuam pseudocylindrical vaj huam sib luag cheeb tsam qhov projection.

Hais txog qhov no, Goode Homolosine projection siv rau dab tsi?

Cov Goode homolosine projection (los yog cuam tshuam Goode homolosine projection ) yog ib daim ntawv qhia pseudocylindrical, vaj huam sib luag, thaj chaw sib xyaw projection siv rau ntiaj teb daim ntawv qhia. Feem ntau nws tau nthuav tawm nrog ntau yam cuam tshuam. Nws cov vaj tse vaj huam sib luag ua rau nws muaj txiaj ntsig zoo rau kev nthuav qhia spatial faib ntawm cov xwm txheej.

Ib yam li ntawd, Goode's interrupted Homolosine projection yog conformal los yog sib npaug sib npaug zos qhov projection? Cov Interrupted Goode Homolosine projection ( Goode tus ) yog ib cuam tshuam , pseudocylindrical, sib npaug - cheeb tsam , composite map qhov projection uas tuaj yeem nthuav qhia tag nrho lub ntiaj teb ntawm ib daim ntawv qhia. Cov av loj thoob ntiaj teb tau nthuav tawm nrog lawv thaj chaw nyob rau hauv kev faib ua feem, nrog tsawg heev cuam tshuam , thiab tsawg kawg tag nrho distortion.

Ib yam li ntawd, vim li cas Paul Goode cuam tshuam nws qhov kev kwv yees Homolosine?

Cov projections cuam tshuam yog li ntawd cov av loj (tshwj tsis yog Antarctica) lossis dej hiav txwv yog txuas. Tag nrho cov latitudes yog kab ncaj. Nyob ntawd yog rau txoj kab ncaj longitude vim qhov cuam tshuam xwm ntawm qhov projection.

Dab tsi daim ntawv qhia qhov projection muaj qhov distortion tshaj plaws?

Hauv feem ntau maps , thaum koj sim kho ib yam ntawm distortion , koj nce lwm hom distortion . Txawm li cas los xij, Mercator yog ib tug ntawm cov tsis tshua muaj daim ntawv qhia uas teb rau latitudinal distortion yog los xyuas kom meej tias longitudinal distortion yog tib yam phem! On ib Mercator projection , Greenland yog roughly tib qhov loj li Africa.
