Yog tias koj tab tom npaj lub davhlau drone, teeb tsa kev tswj hwm lub nkoj, lossis teeb tsa cov ntaub ntawv rau lub app xa khoom, koj feem ntau xav tau qhov tseeb kev sib koom tes ntawm qhov chaw nyob tsis yog lub npe ntawm txoj kev xwb. Cov txheej txheem ntawm kev xa cov ntawv mus rau hauv daim ntawv qhia chaw ntawm txhua qhov chaw GPS hu ua Geocoding.
Geocoding yog dab tsi?
Geocoding yog ib qho txheej txheem suav. Nws siv cov ntawv sau xws li "Empire State Building, NY" lossis "10 Downing Street, London" thiab tshawb nrhiav cov ntaub ntawv loj heev. Nws txhais cov ntawv nyeem, pom cov cuab yeej ciam teb los yog txoj kev ntu hauv nws cov ntaub ntawv, thiab suav cov latitude thiab longitude ntawm qhov chaw nruab nrab ntawm qhov chaw nyob.
Yuav Ua Li Cas Nrhiav Cov Kev Sib Koom Tes ntawm Chaw Nyob
Yog tias koj tsuas yog yuav tsum ua qhov no rau ib lossis ob qhov chaw nyob, koj tuaj yeem siv cov cuab yeej ua qauv.
Siv Google Maps:
- Ntaus qhov chaw nyob rau hauv Google Maps nrhiav bar.
- Tos kom tus pin liab poob rau ntawm qhov chaw.
- Txoj cai-nias ncaj qha rau ntawm tus pin liab (lossis coj mus rhaub thiab tuav yog tias koj nyob ntawm smartphone).
- Ib lub ntsiab lus teb yuav tshwm sim. Thawj yam khoom ntawm cov ntawv qhia zaub mov yuav yog latitude thiab longitude coordinates. Nyem rau lawv kom luam lawv rau hauv koj daim ntawv teev cia.
Geocoding ntau
Yog tias koj muaj daim ntawv tshaj tawm nrog ntau pua qhov chaw nyob uas koj xav tau hloov mus rau hauv GPS kev tswj hwm, ua nws manually yog tsis yooj yim sua. Rau qhov no, cov neeg tsim khoom siv Geocoding APIs muab los ntawm cov tuam txhab xws li Google, Mapbox, lossis OpenStreetMap (Nominatim). Koj xa API cov npe ntawm qhov chaw nyob, thiab nws xa rov qab cov npe ntawm kev tswj hwm hauv vib nas this.
