Ntiaj Teb Science - Daim Ntawv Qhia Ntiaj Teb Qhov Nto

A B
TOPOGRAPHIC MAP A daim ntawv qhia uas qhia cov yam ntxwv ntawm ib cheeb tsam .
CONTOUR kab Ib kab ntawm qhov topographic daim ntawv qhia uas txuas cov ntsiab lus ntawm kev nce siab sib npaug.
CONTOUR INTERVAL Qhov sib txawv ntawm qhov siab ntawm ib kab contour mus rau lwm qhov.

Sib tham, cov yam ntxwv twg yog qhov chaw ntawm topography ntawm ib cheeb tsam?

Topography piav txog lub cev nta ntawm ib cheeb tsam ntawm thaj av. Cov yam ntxwv no feem ntau muaj xws li ntuj tsim xws li roob , tus dej , pas dej, thiab hav . Manmade nta xws li txoj kev, dams, thiab cov nroog kuj yuav suav nrog. Topography feem ntau sau txog ntau qhov siab ntawm ib cheeb tsam uas siv daim ntawv qhia topographical.

Qhov thib ob, thaj av nta ntawm daim ntawv qhia yog dab tsi? Tus kws kos duab siv cov duab lossis duab satellite los tsim kom pom peb sab ntawm lub ntiaj teb nto. Daim ntawv qhia kev pab qhia txog peb yam tseem ceeb ntawm thaj av nta: roob , plains, thiab toj siab. lub hauv paus yuav npog ntau square kilometers. Ib pawg ntawm roob hu ua roob roob.

Ib yam li ntawd, koj tuaj yeem nug, yuav ua li cas lub cev ntaj ntsug tuaj yeem sawv cev ntawm daim ntawv qhia?

Daim duab qhia lub cev feem ntau suav nrog ntau ntawm tib cov ntaub ntawv pom ntawm kev nom kev tswv daim ntawv qhia , tab sis lawv lub hom phiaj tseem ceeb yog rau qhia landforms zoo li suab puam, roob thiab tiaj. Lawv topography style nthuav qhia tag nrho cov duab zoo dua ntawm thaj chaw hauv zos.

Qhov siab qhia li cas hauv daim duab qhia?

Cov no muab qhov tseeb qhov siab saum toj no hiav txwv theem ntawm ib tug point ntawm a daim ntawv qhia . Ib tug triangulation ncej kuj yog siv los ua qhia qhov siab thiab kos raws li ib qho chaw hauv daim duab peb sab xiav. Contours yog cov kab hauv kev xav ntawm ib qho daim ntawv qhia koom nrog qhov chaw sib npaug qhov siab . Cov cheeb tsam sib txawv qhov siab yog qhia los ntawm cov xim sib txawv.
