Yog tias koj nyob ntawm thaj tsam sab nraud ntawm ib lub nroog lossis hauv ib lub zos, ces feem ntau nws yuav nyuaj heev kom tau txais daim duab qhia thaj chaw rau tib GPS navigator. Tab sis hmoov zoo, tshwj xeeb cov kev pab cuam twb tau tsim uas tso cai rau koj los ua daim duab qhia kev ntawm thaj chaw ntawm ntau hom kev sib xyaw: kev nyem, qhia cov zos thiab kev sib tshuam, txoj kev thiab lwm cov ntsiab ntawm cov duab qhia niaj hnub.

Compass, koob yees duab, khoos phis tawj, tshuab tshwj xeeb rau kev tsim cov duab qhia chaw
Cov Lus Qhia

Qhov zoo ntawm daim duab qhia thiab nws cov nplai nyob ntawm tsis yog tsuas yog nyob ntawm tus sau kev paub, tab sis kuj tseem nyob ntawm qhov zoo ntawm cov duab thaij, yog tias qhov program siv duab thaij duab ib yam. Feem ntau cov feem ntau, kab ntawv yog tsim tshwj xeeb rau GPS navigator, i.e. nrog kev ncua ntawm txoj hauv kev. Lawv tau ua raws ntawm cov duab ntawm vector, vim tias yog qhov twg los raster, i.e. duab? suav nrog cov pixels, tom qab ntawd thaum daim ntawv qhia loj, qhov zoo yuav poob qis thiab nws yuav nyuaj rau pom dab tsi.

Txhawm rau tsim cov duab qhia thaj chaw, siv cov haujlwm tshwj xeeb - GIS (Cov Ntaub Ntawv Xov Xwm Nyob Thaj Tsam). Nov yog software khoom lag luam uas muab rau cov neeg siv muaj peev xwm tshawb nrhiav, kho cov duab qhia chaw thiab ntxiv cov ntaub ntawv ntxiv txog cov khoom (tsev siab, chaw nyob, naj npawb ntawm cov neeg nyob hauv, thiab lwm yam).
Kauj ruam 3
GIS tso cai rau koj los tswj DBMS, muaj tus tsim ntawv tsim kho rau vector thiab raster duab, thiab ntxiv rau cov cuab yeej kev tshuaj xyuas uas siv tsis tsuas yog nyob hauv cartography, tab sis kuj muaj nyob hauv lwm yam kev lag luam. Cov vev xaib yog khaws cia hauv tshuab hluav taws xob thiab koj tuaj yeem luam lawv yog tias koj xav tau. Txhawm rau nrhiav GIS cov kev pabcuam hauv Is Taws Nem, nkag mus rau cov lus nug tsim nyog hauv lub tshuab tshawb nrhiav, piv txwv: "cov kev pabcuam GIS nrov" thiab xaiv qhov yooj yim tshaj plaws raws li cov neeg siv cov ntawv.

Siv AutoCADMAP 3D los tsim 3D daim ntawv qhia. Qhov kev zov me nyuam muaj qhov ua kom dav, yog li nws tsis yooj yim siv. Tab sis yog tias koj nyeem cov ntawv nyeem tsim nyog, tom qab ntawd txhua yam zoo li yooj yim heev thiab pom tau tseeb. AutoCAD tsim cov duab vector - qhov tseeb, cov lus piav qhia ntawm cov khoom txheej thaum ub, rau ntu, piv txwv li, txoj haujlwm ntawm nws qhov pib thiab xaus cov ntsiab lus, thiab cov duab rov ua dua tshiab thiab rov ua dua thaum teev, yog li qhov tsis zoo yog qhov tsawg.
Kauj ruam 5
Tsis muaj qee qhov kev paub ntawm GIS thiab kos duab, koj yuav tsis tuaj yeem tsim daim duab qhia kev ntawm thaj chaw. Yog li ntawd, nyeem cov ntaub ntawv tsim nyog ua ntej mus yuav cov kev pab cuam thiab siv cov kev sib tham, kev txhawb nqa kev txawj ntse thiab txhua yam ntawv tuaj yeem pab.
Kauj Ruam 6
Tab sis los tsim daim ntawv qhia ua ntu zus, koj xav tau lub koob taw qhia. Ua ntej, teeb lub cim av - nws tuaj yeem yog ntoo, dej ntws, hav iav lossis ib lub teeb txawb, tus pej thuam, thiab lwm yam. Rau kev coj ua txhua yam rau ntawm daim duab qhia, txuas daim duab ntawm daim duab ntawv nrog cov khoom tiag. Teeb tsa tus neeg siv cov koob taw qhia ntawm daim pheem thib feem ntau yog siv rau thaj chaw uas nws nyuaj kom nrhiav cov chaw siv (hav zoov, suab puam).
Kauj Ruam 7
Tom qab txiav txim siab txog tus caws pliav, xaiv cov kev taw qhia ntawm kev mus ncig thiab kev coj tus kheej. Yog tias txoj hauv kev tsis yog txoj kab ncaj ncaj, tom qab ntawd koj yuav tsum txiav txim siab qhov kev ncua deb thiab, tom qab dhau mus, hloov txoj kev coj. Los yog xaiv thaj av ntawm daim pheem thib, nrhiav nws thiab tsuas yog tom qab ntawd hloov txoj kev coj ntawm nws txav mus.
