LiDAR, e emetse Light Detection and Ranging, e emela sehlohlolong sa theknoloji ea remoutu ea kutlo. E sebetsa ka ho ntša maballo a khanya, hangata joalo ka li-laser tsa pulsed, 'me e lekanya nako e nkuoang hore maballo ana a khutlele morao ho tsoa linthong. Ho jala ka lebelo le khanyang, hoo e ka bang 3 × 108limithara ka motsotsoana, LiDAR e bala ka nepo sebaka sa ntho e itseng e sebelisa foromo: Sebaka = Lebelo × Nako. Mohlolo ona oa theknoloji o fumane lits'ebetso tse fapaneng lefats'eng ka bophara, ho fetola maemo ho tloha ho likoloi tse ikemetseng ho ea ho tlhokomelo ea tikoloho, le ho tloha ho thero ea litoropo ho ea ho tse sibollotsoeng ke baepolli ba lintho tsa khale. Patlisiso ena e batsi e batlisisaLikopo tse 10 tsa bohlokoa tsa LiDAR, e bonts'ang tšusumetso ea eona e kholo mafapheng a fapaneng.
1. LiDAR ea Likoloi
LiDAR e bohlokoa sebakeng sa ho khanna ka boithaopo. E hlahisa limmapa tse rarahaneng tsa tikoloho ka ho ntša le ho hapa maqhubu a laser. Ts'ebetso ena e lumella likoloi tse itaolang ho tseba likoloi tse ling, batho ba tsamaeang ka maoto, litšitiso le matšoao a tsela ka nako ea nnete. Litšoantšo tsa 3D tse hlahisoang ke LiDAR li thusa likoloi tsena ho tsamaea libakeng tse rarahaneng, ho netefatsa ho etsa liqeto ka potlako le ka mokhoa o sireletsehileng. Libakeng tsa litoropo, mohlala, LiDAR e bohlokoa bakeng sa ho bona likoloi tse emeng, ho lebella metsamao ea batho ba tsamaeang ka maoto, le ho boloka pono e nepahetseng maemong a leholimo a thata.

2. 'Mapa oa Remote Sensing
LiDAR e ntlafatsa haholo ho nepahala le katleho ea 'mapa oa libaka. E sebelisoa ho tsoa lifofaneng kapa lisathelaete, e bokella ka potlako lintlha tsa boemo ba leholimo libakeng tse kholo. Lintlha tsena li bohlokoa bakeng sa moralo oa litoropo, tlhahlobo ea likotsi tsa likhohola, le moralo oa litšebeletso tsa lipalangoang. LiDAR e thusa baenjiniere ho tseba mathata a sebaka ha ba rera litsela tse kholo, tse lebisang litseleng tse fokotsang tšusumetso ea tikoloho le ho ntlafatsa katleho ea kaho. Ho feta moo, LiDAR e ka senola likarolo tse patiloeng tsa boemo ba leholimo ka tlas'a limela, tse ipakang e le tsa bohlokoa liphuputsong tsa baepolli ba lintho tsa khale le tsa jeoloji.

3. Meru le Temo:
Merung, LiDAR e sebelisoa ho lekanya bolelele ba lifate, ho teteana le litšobotsi tsa sebopeho sa naha, tse bohlokoa bakeng sa taolo le paballo ea meru. Tlhahlobo ea data ea LiDAR e thusa litsebi ho hakanya kholo ea meru, ho lekola bophelo bo botle ba meru le ho lekola likotsi tsa mollo. Temong, LiDAR e ts'ehetsa lihoai ho lekola kholo ea lijalo le mongobo oa mobu, ho ntlafatsa mekhoa ea ho nosetsa le ho ntlafatsa chai.
4. Distributed Temperature Sensing:
LiDAR e bohlokoa haholo ho utloeng mocheso o ajoang, e leng karolo ea bohlokoa lits'ebetsong tse kholo tsa indasteri kapa likhoeleng tsa phetisetso ea matla. TheDTS LiDARe lekola kabo ea mocheso e le hole, e hloaea libaka tse ka bang teng ho thibela liphoso kapa mello, ka ho etsa joalo e netefatsa polokeho ea indasteri le ho ntlafatsa ts'ebetso ea matla.
5. Lipatlisiso le Tšireletso ea Tikoloho:
LiDAR e bapala karolo ea bohlokoa lipatlisisong tsa tikoloho le boitekong ba paballo. E sebelisetsoa ho beha leihlo le ho hlahloba liketsahalo tse kang ho phahama ha leoatle, ho qhibiliha ha leqhoa le ho senngoa ha meru. Bafuputsi ba sebelisa lintlha tsa LiDAR ho latela sekhahla sa ho khutla ha leqhoa le ho lekola litlamorao tsa phetoho ea maemo a leholimo tikolohong. LiDAR e boetse e beha leihlo boleng ba moea libakeng tsa litoropo le temo, e kenya letsoho ntlafatsong ea maano a sebetsang a tikoloho.
6. Meralo le Tsamaiso ea Litoropo:
LiDAR ke sesebelisoa se matla ho rala le taolong ea litoropo. Pokello ea lintlha tse phahameng tsa 3D e lumella baetsi ba meralo ho utloisisa hamolemo mehaho ea libaka tsa litoropo, ho thusa ntlafatsong ea libaka tse ncha tsa bolulo, litsi tsa khoebo le mehaho ea sechaba. Lintlha tsa LiDAR li bohlokoa ho ntlafatseng litsela tsa lipalangoang tsa sechaba, ho lekola phello ea meaho e mecha libakeng tsa litoropo, le ho lekola tšenyo ea meaho kamora likoluoa.
7. Thuto ea lintho tsa khale:
Theknoloji ea LiDAR e fetotse lefapha la thuto ea khale, ho bula menyetla e mecha ea ho sibolla le ho ithuta tsoelo-pele ea khale. Bokhoni ba eona ba ho phunyeletsa limela tse teteaneng bo entse hore ho sibolloe lintho tsa khale tse patiloeng le mehaho. Ka mohlala, merung ea tropike ea Amerika Bohareng, LiDAR e senotse libaka tse likete tsa Maya tse neng li sa tsejoe pele, ho matlafatsa tsebo ea rona ka mekhatlo ena ea khale haholo.
8. Taolo ea Likoluoa le Karabelo ea Tšohanyetso:
LiDAR e bohlokoa haholo taolong ea likoluoa le maemong a karabelo ea tšohanyetso. Ka mor'a liketsahalo tse kang likhohola kapa litšisinyeho tsa lefatše, e potlakela ho hlahloba tšenyo, ho thusa boitekong ba pholoso le ho tsosolosa. LiDAR e boetse e lekola tšusumetso ea lits'ebetso tsa ts'ebetso, ho ts'ehetsa merero ea tokiso le kaho bocha.

9. Patlisiso ea Bofofisi le Sebaka:
Bofofising ba lifofane, LiDAR e sebelisoa bakeng sa lipatlisiso tsa sepakapaka, litekanyo tsa ho lekanya joalo ka botenya ba maru, litšila tsa moea le lebelo la moea. Ha ho hlahlojoa sepaka-paka, e hlomella li-probes le lisathelaete bakeng sa litlhahlobo tse qaqileng tsa boemo ba lipolanete. Mohlala, mesebetsi ea ho hlahloba Mars e sebelisa LiDAR bakeng sa 'mapa o felletseng le tlhahlobo ea jeoloji ea sebaka sa Mars.
10. Sesole le Tšireletso:
LiDAR e bohlokoa lits'ebetsong tsa sesole le ts'ireletso bakeng sa boithuto, boitsebahatso ba sepheo, le tlhahlobo ea sebaka. E thusa ho tsamaea libakeng tse rarahaneng tsa ntoa, ho lemoha litšokelo, le ho rera ka maqheka. Li-Drones tse nang le LiDAR li etsa mesebetsi ea tlhahlobo e nepahetseng, li fana ka bohlale ba bohlokoa.
