Daim duab ntawm cov khoom loj tuaj yeem muab tau rau ntawm daim ntawv lossis lwm qhov nruab nrab tsuas yog hauv daim ntawv txo qis. Qhov no feem ntau siv rau ntau daim duab qhia ntawm thaj chaw. Cov nplai ntawm daim duab qhia yog qhov sib piv ntawm qhov ntev ntawm txoj kab kos ntawm ob lub ntsiab lus ntawm txoj phiaj xwm lossis daim ntawv qhia mus rau tib yam deb ntawm hauv av. Paub txog cov nplai yog qhov tsim nyog txhawm rau ntsuas qhov deb ntawm daim duab kos.
Cov Lus Qhia

Feem ntau, qhov ntsuas ntsuas ntawm txhua daim duab kos lossis daim duab kos yog qhia hauv nws cov lus dab neeg - cov kab lus piav qhia txuas nrog. Cov nplai tuaj yeem muab cov duab los ntsuas lossis cov ntawv nyeem, uas qhia txog ntau npaum li cas metres lossis km rau hauv av yog sib npaug li 1 cm ntawm qhov kev ncua deb hauv daim duab no. Qhov ntsuas qhov ntsuas ntawm 1: 50,000 txhais tau hais tias 1 cm plotted hauv daim duab qhia no yog sib npaug li 500 metres lossis 0.5 km ntawm xwm. Qhov ntsuas loj dua, tus lej tsawg dua tau qhia hauv nws tus lej. Cov duab qhia chaw sab saum toj ntawm cov teev 1: 10000 thiab loj dua yog cais raws li cov ncauj lus qhia.

Kev txiav txim siab hauv daim duab qhia chaw thaj chaw ntawm thaj chaw nruab nrab ntawm cov av nruab nrab ntawm nws. Xaiv ob lub cim xeeb ceem ntawm nws uas tuaj yeem pom yooj yim los ntawm cov duab satellite ntawm thaj chaw. Feem ntau, nws yooj yim siv rau qhov kev sib tshuam ntawm txoj kev loj lossis txhim kho txoj kev loj, kev loj.

Nrhiav ob lub ntsiab lus no los ntawm cov duab satellite ntawm thaj chaw. Siv cov cuab yeej ntsuas los ntsuas qhov kev ncua deb ntawm lawv. Thaum lub cuab yeej tshuab txais, ib lub phaj tshwm, qhov twg qhov kev ncua deb ntawm ob lub ntsiab lus koj teev hauv qhov chaw duab satellite yuav tau ncaj qha. Teem cov kev ntsuas ntawm kev ntsuas kom yooj yim rau koj - meters, km.
