Cov no daim ntawv qhia yog siv rau ntau daim ntawv thov, los ntawm kev mus pw hav zoov, yos hav zoov, nuv ntses, thiab hiking mus rau kev npaj hauv nroog, kev tswj hwm, thiab kev soj ntsuam. Cov yam ntxwv tshwj xeeb tshaj plaws ntawm a daim ntawv qhia topographic yog hais tias peb-dimensional zoo ntawm lub ntiaj teb nto yog qauv los ntawm lub siv ntawm contour kab.

Ib yam li ntawd, nws raug nug, cov cim dab tsi siv rau ntawm daim ntawv qhia topographic?

Topographic Map Lus dab neeg thiab cov cim

  • Cov kab xim av - contours (nco ntsoov tias lub sijhawm sib txawv)
  • Cov kab dub - txoj kev, kev tsheb ciav hlau, txoj kev taug, thiab ciam teb.
  • Cov kab liab - kab tshawb fawb (nroog nroog, thaj tsam, thiab kab kab)
  • Cov cheeb tsam xiav - ntws thiab cov khoom yog rau cov dej loj dua.
  • Cov cheeb tsam ntsuab - cov nroj tsuag, feem ntau yog ntoo lossis nplooj ntoo tuab.

Tsis tas li ntawd, cov ntaub ntawv twg tau pom nyob rau hauv daim duab qhia chaw? Piav: A daim ntawv qhia topographic qhia cov ntaub ntawv hais txog tej yam ntuj tso thiab tib neeg tsim, cov cim qhia av thiab cov qauv thiab cov ntaub ntawv hais txog qhov siab thiab txoj kab nqes. Nws tsis qhia qhov kev nplij siab ntawm txhua cheeb tsam uas tau muab tso rau hauv cov pobzeb squares lossis kev hloov pauv ntawm huab cua ntawm thaj chaw.

Tom qab ntawd, lo lus nug yog, vim li cas daim ntawv qhia saum toj kawg nkaus tseem ceeb?

Topographic maps yog ib tseem ceeb cuab yeej vim tias lawv tuaj yeem sawv cev rau thaj chaw peb sab hauv ob qhov ntev. Ib tug neeg uas nyeem tau a npo map tuaj yeem nrhiav pom qhov chaw ntawm peaks, hav, ridges thiab eeb, ntawm lwm yam av nta.

Peb hom daim ntawv qhia cov cim yog dab tsi?

Muaj peb hom daim ntawv qhia cov cim:

  • Point Symbols = lub tsev, dipping tanks, trigonometrical beacons.
  • Kab Cim = railways, txoj kev, fais fab, kab xov tooj.
  • Cov cim thaj chaw = kev cog qoob loo, vaj txiv hmab txiv ntoo thiab vaj txiv hmab, lauj kaub.
