Vertical exaggeration formula: VE=(real world units of horizontal scale) / (real world units of vertical scale). Ua piv txwv rau 1:50000 daim duab qhia chaw, peb tuaj yeem teeb tsa kab rov tav (x axis) ntawm qhov profile tib yam li daim ntawv qhia.
Vim li cas peb thiaj suav cov kev tshaj tawm ntsug?
Vertical exaggeration yog tsim nyog los txhais kab ntawm qhov pom kev pom, tab sis yuav tsum tau txiav txim siab ua ntej dhia mus rau qhov kev txiav txim siab txog kev thauj mus los nce toj. Qhov tseeb nplai qhov profile tsuas yog ua tau nyob rau qhov luv luv nrog rau qhov chaw siab heev.
Yuav ua li cas koj npaj qhov kev tshaj tawm ntsug?
Yuav kom suav cov kev tshaj tawm ntsug, faib lub ntiaj teb tiag tiag ntawm kab rov tav los ntawm lub ntiaj teb tiag tiag ntawm cov nplai ntsug. Xyuas kom tseeb tias tib units tau siv nyob rau hauv tus lej thiab tus lej ntawm kev faib. Tsis tas li ntawd ib txwm qhia tus nqi tshaj tawm ntsug ntawm koj daim duab profile.
Dab tsi yog qhov sib txawv ntawm kev tshaj tawm ntsug thiab gradient?
Qhov gradient ntawm 1:126.5 txhais tau tias rau txhua txhua 126.5, units uas koj mus rau kab rov tav, yuav muaj qhov siab ntawm 1 units. Vertical exaggeration yog qhov loj uas qhov ntsuas ntsug ntawm qhov hla ntu loj dua li kab rov tav.
Vertical scale yog dab tsi?
Vertical scale yog lub peev xwm txav ib qho piv txwv mus rau lub tshuab muaj zog dua. Kab rov tav scale yog qhovmuaj peev xwm ntxiv ntau lub tshuab rau ib qho kev pabcuam, qhov system lossis daim ntawv thov. Vertical scaling is far more limit than horizontal scaling because there is a limit to the size of ib lub tshuab.
