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.

Daim ntawv qhia dab tsi qhia txog qhov chaw ntawm thaj chaw?
Ntiaj Teb Kev Tshawb Fawb - Daim Ntawv Qhia Lub Ntiaj Teb Qhov Nto A B TOPOGRAPHIC MAP Daim duab qhia chaw uas qhia txog cov yam ntxwv ntawm thaj chaw. CONTOUR LINE Ib kab ntawm daim ntawv qhia saum toj kawg nkaus uas txuas cov ntsiab lus ntawm qhov siab sib npaug. CONTOUR INTERVAL Qhov txawv ntawm qhov nce ntawm ib kab contour mus rau lwm qhov
Qhov kev hloov pauv twg yuav hloov daim duab A rau hauv daim duab B?
Ob daim duab tau hais tias yuav sib haum xeeb yog tias ib tus tuaj yeem tau txais los ntawm lwm tus los ntawm ib ntu ntawm kev txhais lus, kev xav, thiab kev sib hloov. Cov duab sib xws muaj qhov loj thiab zoo tib yam. Txhawm rau hloov daim duab A rau hauv daim duab B, koj yuav tsum xav txog nws hla y-axis thiab txhais ib chav nyob rau sab laug
Daim duab qhia chaw muaj txiaj ntsig dab tsi tshaj li daim duab?
Daim duab saum toj kawg nkaus muaj qhov zoo hauv qab no ntawm daim duab qhia: (1) Nws muab cov duab pom hauv av tam sim no uas tsis muaj daim ntawv qhia sib npaug. (2) Nws tau yooj yim dua. Daim duab yuav nyob rau hauv txhais tes ntawm tus neeg siv nyob rau hauv ob peb teev tom qab nws coj; daim ntawv qhia yuav siv sij hawm ntau lub hlis los npaj
Dab tsi yog qhov txawv ntawm lub xeev daim duab kos duab thiab daim duab ua haujlwm?
Lub xeev daim duab qauv yog siv los qhia qhov sib lawv liag ntawm lub xeev uas ib yam khoom mus dhau, qhov ua rau kev hloov ntawm ib lub xeev mus rau lwm qhov thiab qhov kev txiav txim uas tshwm sim los ntawm lub xeev hloov. Daim duab ua haujlwm yog ntws ntawm kev ua haujlwm yam tsis muaj qhov tshwm sim (kev tshwm sim) mechanism, lub xeev tshuab yog suav nrog lub xeev triggered
Dab tsi ntawm daim duab yuav zoo tshaj rau kev qhia txhais tau tias rau ntau yam kev kho mob?
Ib Bar Graph. Bar graphs yog siv los sib piv cov khoom ntawm cov pab pawg sib txawv lossis taug qab kev hloov pauv sijhawm. Txawm li cas los xij, thaum sim ntsuas qhov kev hloov pauv thaum lub sijhawm, cov kab lus yog qhov zoo tshaj plaws thaum cov kev hloov pauv loj dua
