Cov ntaub ntawv topographic yog cov ntaub ntawv hais txog cov qhov siab ntawm qhov chaw ntawm lub ntiaj teb. Ob yam ntawd cov ntaub ntawv hom feem ntau siv nrog GeoPads. Thawj yog cov ntaub ntawv uas sawv cev rau cov ntaub ntawv feem ntau pom ntawm a daim ntawv qhia topographic quadrangle , xws li cov kab contour, txoj kev, kwj deg, railroads, lub zos, thiab lwm yam.
Nyob rau hauv no, cov ntaub ntawv twg yog qhia nyob rau hauv topographic maps?
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.
Ib sab saum toj no, yuav ua li cas nce siab yog qhia nyob rau hauv daim ntawv qhia topographic? Cov qhov siab ntawm hiav txwv theem yog xoom meters. Contour kab yog siv los qhia qhov siab ntawm a daim ntawv qhia topographic . Contour kab. Kab lossis isolines ntawm a daim ntawv qhia uas txuas cov ntsiab lus nrog tib yam qhov siab.
Yog li ntawd, daim ntawv qhia topography qhia li cas?
Topographic maps yog cov ncauj lus kom ntxaws, muaj tseeb cov duab sawv cev ntawm cov yam ntxwv uas tshwm sim ntawm lub ntiaj teb nto. Cov yam ntxwv no suav nrog: kab lis kev cai: txoj kev, vaj tse, kev loj hlob hauv nroog, kev tsheb ciav hlau, tshav dav hlau, cov npe ntawm cov chaw thiab thaj chaw, thaj tsam tswj hwm, xeev thiab thoob ntiaj teb ciam teb, ciam teb.
Dab tsi yog peb lub ntsiab lus siv hauv daim duab qhia?
Ib co nta ntawm daim ntawv qhia muaj xws li nplai, cim, thiab kab sib chaws
- Scale. Txhua daim ntawv qhia yog cov qauv ntsuas ntawm kev muaj tiag.
- Cov cim. Cartographers siv cov cim los sawv cev rau thaj chaw.
- Daim phiaj.
- Lwm Daim Ntawv Qhia Nta: DOGSTAILS.
- Daim duab qhia kev.
- Kev Tshawb Fawb thiab Kev Tshawb Fawb Chaw Taws Teeb.
- Yuav ua li cas Maps tau ua.
- Hom Maps.

Txoj kev faib cov ntaub ntawv twg muab cov ntaub ntawv sib npaug ntawm cov ntaub ntawv lossis cov kev tshuaj xyuas hauv txhua chav kawm cov ntaub ntawv?
Quantile. txhua chav kawm muaj cov yam ntxwv sib npaug. Ib qho kev faib tawm ntau yog zoo haum rau cov ntaub ntawv faib tawm. Quantile muab tib tus lej ntawm cov ntaub ntawv muaj nuj nqis rau txhua chav kawm
Cov yam ntxwv ntawm cov ntaub ntawv twg yog qhov ntsuas ntawm tus nqi uas cov ntaub ntawv muaj nuj nqis heev?
Variation: Ib qho kev ntsuas ntawm tus nqi uas cov ntaub ntawv muaj nuj nqis sib txawv. ? Kev faib tawm: Cov xwm txheej lossis cov duab ntawm kev sib kis ntawm cov ntaub ntawv hla ntau qhov tseem ceeb (xws li tswb-puab). ? Outliers: Cov qauv piv txwv uas nyob deb heev ntawm feem ntau ntawm lwm cov qauv nqi
Daim ntawv qhia dab tsi qhia txog qhov chaw 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
Thaum muab piv cov qauv sau rau ib tus neeg raug liam cov ntaub ntawv lub hnub nyoog sib txawv ntawm cov ntaub ntawv yuav tsum tsis pub tshaj kaum ob lub hlis?
Thaum piv cov qauv sau rau tus neeg raug liam? cov ntaub ntawv, lub hnub nyoog sib txawv ntawm cov ntaub ntawv yuav tsum tsis pub ntau tshaj rau rau kaum ob lub hlis. Tus lej txaus ntawm tus qauv yog qhov tseem ceeb rau kev txiav txim siab qhov tshwm sim ntawm kev sib piv
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
