Google Maps, nrog cov kab contour

Google Maps ntxiv qhov kev xaiv tseem ceeb rau ntawm daim ntawv qhia zaub, uas muaj cov kab contour los ntawm ib theem zoom.

Qhov no yog qhib rau sab laug vaj huam sib luag "Relief" thiab nyob rau hauv lub floating khawm koj tuaj yeem qhib lossis deactivate qhov pom ntawm nkhaus.

Lub hauv paus ntawm cov kab sib chaws no uas Google tau ua ke yog cov qauv av digital pib tsim los ntawm NASA thiab txuas ntxiv los ntawm USGS, uas yog hu ua SRTM-90m. Cov haujlwm no tau pom nyob hauv Google Maps, hauv Google Earth ntawm qib qauv digital. Txoj kev daws teeb meem kab rov tav yog 90 meters (nws txawv ntawm latitude) thiab raws li qhov nkhaus no tau raug muab txhais (Nws xav tias hauv Tebchaws Asmeskas nws mus rau 30 metres tab sis nws tsis yog siv rau peb). Qhov kev ua txhaum ntsug yog kwv yees 16 hli.

Lub download ntawm no contour yuav ua tau los ntawm AutoCAD, muab cov ntsiab lus ntawm ib kab sib chaws thiab tsim ib qauv qauv nrog nws cov curves.

Kauj Ruam 1. Nthuav thaj chaw uas peb xav tau Google Earth cov qauv digital.

Kauj Ruam 2. Ntshuam cov qauv digital.

Siv AutoCAD, tau nruab Plex.Earth Add-ins. Hauv txoj ntsiab cai, koj yuav tsum pib qhia ntawv.

Tom qab ntawd peb xaiv "Los ntawm GE Saib" kev xaiv nyob rau hauv Terrain tab. Nws yuav nug peb kom paub meej tias 1,304 cov ntsiab lus yuav raug ntshuam; tom qab ntawd nws yuav nug peb kom paub meej tias yog peb xav kom txoj kab ntawm cov contour raug tsim. Thiab npaj tau; Google Earth contour kab hauv AutoCAD.

Kauj ruam 3. Xa mus rau Google Ntiaj Teb

Thaum xaiv cov khoom, peb xaiv KML Export kev xaiv, ces peb qhia tau hais tias tus qauv yog hloov mus rau thaj av thiab thaum kawg uas nws yuav qhib rau Google Earth.

Thiab yog muaj peb muaj qhov tshwm sim.

De ntawm no koj tuaj yeem luam tau cov ntaub ntawv kmz uas peb tau siv nyob rau hauv qhov kev piv txwv no.

Ntawm no koj tuaj yeem download tau lub Plex.Earth plugin rau AutoCAD.
