Ingolise ho Mecha ea Rona ea Litaba tsa Sechaba bakeng sa Poso e Potlakileng
LiDAR, e emetseng ho Lemoha Leseli le Boemo, e emela sehlohlolo sa theknoloji ea ho lemoha hole. E sebetsa ka ho ntša mahlaseli a leseli, hangata e le li-laser tse pulsed, 'me e lekanya nako e nkiloeng hore mahlaseli ana a bonahale ho tloha linthong. E ata ka lebelo la leseli, hoo e ka bang 3×108limithara ka motsotsoana, LiDAR e bala sebaka ho ea nthong ka nepo e sebelisa mokhoa ona: Sebaka = Lebelo × Nako. Mohlolo ona oa theknoloji o fumane lits'ebetso tse fapaneng lefatšeng ka bophara, o fetola masimo ho tloha likoloing tse ikemetseng ho ea tlhokomelong ea tikoloho, le ho tloha mererong ea litoropo ho ea ho lintho tse sibolotsoeng tsa khale. Phuputso ena e felletseng e kenella hoLisebelisoa tse 10 tsa bohlokoa tsa LiDAR, e bonts'ang tšusumetso ea eona e tebileng makaleng a fapaneng.
1. LiDAR ea Likoloi
LiDAR ke ea bohlokoa lefapheng la ho khanna ka boikemelo. E hlahisa limmapa tse rarahaneng tsa tikoloho ka ho ntša le ho hapa li-pulse tsa laser. Ts'ebetso ena e lumella likoloi tse itsamaisang ho tseba likoloi tse ling, ba tsamaeang ka maoto, litšitiso le matšoao a tsela ka nako ea sebele. Litšoantšo tsa 3D tse hlahisoang ke LiDAR li nolofalletsa likoloi tsena ho tsamaea libakeng tse rarahaneng, ho netefatsa ho etsa liqeto ka potlako le ka mokhoa o sireletsehileng. Libakeng tsa litoropo, mohlala, LiDAR ke ea bohlokoa bakeng sa ho lemoha likoloi tse sa emeng, ho lebella metsamao ea ba tsamaeang ka maoto, le ho boloka kutloisiso e nepahetseng maemong a leholimo a thata.

2. 'Mapa oa ho Lemoha hole
LiDAR e ntlafatsa haholo ho nepahala le bokgoni ba ho etsa 'mapa wa sebaka. Ha e sebediswa ho tswa difofaneng kapa disathelaeteng, e bokella ka potlako tlhahisoleseding ya sebaka hodima dibaka tse kgolo. Lintlha tsena di bohlokwa bakeng sa moralo wa ditoropo, tlhahlobo ya dikotsi tsa dikgohola, le moralo wa meralo ya motheo ya dipalangwang. LiDAR e thusa baenjiniere ho hlwaya diphephetso tsa sebaka ha ba rera ditsela tse ntjha tsa lewatle, e leng se lebisang ditseleng tse fokotsang tshusumetso ya tikoloho le ho eketsa bokgoni ba kaho. Ho feta moo, LiDAR e ka senola dikarolo tse patilweng tsa sebaka ka tlasa dimela, e leng se ipakang e le tsa bohlokwa diphuputsong tsa baepolli ba dintho tsa kgale le tsa jeoloji.

3. Meru le Temo:
Temo ea meru, LiDAR e sebelisoa ho lekanya bolelele ba lifate, bongata le litšobotsi tsa sebopeho sa naha, tse leng tsa bohlokoa bakeng sa taolo le paballo ea meru. Tlhahlobo ea data ea LiDAR e thusa litsebi ho hakanya biomass ea meru, ho beha leihlo bophelo bo botle ba meru, le ho lekola likotsi tsa mollo. Temo, LiDAR e tšehetsa balemi ho beha leihlo kholo ea lijalo le mongobo oa mobu, ho ntlafatsa mekhoa ea nosetso le ho ntlafatsa chai ea lijalo.
4. Temoho e Ajoang ea Thempereichara:
LiDAR e bohlokoa haholo ho lemoheng mocheso o ajoang, e leng karolo ea bohlokoa liindastering tse kholo kapa mehala ea phetisetso ea matla.DTS LiDARe lekola kabo ea mocheso hole, e khetholla libaka tse ka bang teng tsa ho chesa ho thibela liphoso kapa mollo, ka hona e netefatsa polokeho ea indasteri le ho ntlafatsa ts'ebeliso e ntle ea matla.
5. Patlisiso le Tšireletso ea Tikoloho:
LiDAR e bapala karolo ea bohlokoa boitekong ba lipatlisiso tsa tikoloho le paballo. E sebelisoa ho beha leihlo le ho sekaseka liketsahalo tse kang ho phahama ha bophahamo ba leoatle, ho qhibiliha ha leqhoa le ho rengoa ha meru. Bafuputsi ba sebelisa lintlha tsa LiDAR ho latela sekhahla sa ho khutla ha leqhoa le ho lekola litlamorao tsa phetoho ea tlelaemete tikolohong ea tikoloho. LiDAR e boetse e beha leihlo boleng ba moea libakeng tsa litoropo le tsa temo, e leng se tlatsetsang nts'etsopele ea maano a sebetsang a tikoloho.
6. Moralo le Tsamaiso ea Litoropo:
LiDAR ke sesebelisoa se matla sa moralo le tsamaiso ea litoropo. Pokello ea lintlha tsa 3D tse nang le qeto e phahameng e lumella baqapi ho utloisisa hamolemo meaho ea libaka tsa litoropo, e thusang nts'etsopele ea libaka tse ncha tsa bolulo, litsi tsa khoebo le libaka tsa sechaba. Lintlha tsa LiDAR li bohlokoa ho ntlafatseng litsela tsa lipalangoang tsa sechaba, ho lekola tšusumetso ea meaho e mecha holim'a libaka tsa litoropo, le ho lekola tšenyo ea meralo ea motheo kamora likoluoa.
7. Thuto ea lintho tsa khale:
Theknoloji ea LiDAR e fetotse lefapha la thuto ea lintho tsa khale, e bula menyetla e mecha ea ho sibolla le ho ithuta tsoelo-pele ea boholo-holo. Bokhoni ba eona ba ho kenella limela tse teteaneng bo lebisitse ho sibolloeng ha lintho tsa khale le meaho e patiloeng. Mohlala, merung ea tropike ea Amerika Bohareng, LiDAR e senotse libaka tse likete tsa Maya tse neng li sa tsejoe pele, e leng se ntlafatsang tsebo ea rona ka lichaba tsena tsa boholo-holo haholo.
8. Taolo ea Likoluoa le Karabelo ea Maemo a Tšohanyetso:
LiDAR e bohlokoa haholo taolong ea likoluoa le maemong a tšohanyetso. Kamora liketsahalo tse kang likhohola kapa litšisinyeho tsa lefatše, e hlahloba tšenyo ka potlako, e thusa boitekong ba pholoso le ba ho hlaphoheloa. LiDAR e boetse e beha leihlo tšusumetso ea meralo ea motheo, e tšehetsa merero ea tokiso le kaho bocha.
→Sengoloa se Amanang:Tšebeliso ea Laser ho Sireletsehile, ho lemoha le ho beha leihlo
9. Lifofane le ho Lekola Sebaka:
Lefapheng la lifofane, LiDAR e sebedisetswa dipatlisiso tsa sepakapaka, ho lekanya diparamitha tse kang botenya ba maru, tshilafatso ya moya le lebelo la moya. Lefapheng la ho hlahloba sepakapaka, e hlomella di-probe le di-satellite bakeng sa ditekolo tse qaqileng tsa sebopeho sa dipolanete. Mohlala, mesebetsi ya ho hlahloba Mars e sebedisa LiDAR bakeng sa ho etsa dimmapa tse felletseng le tlhahlobo ya jeoloji ya bokahodimo ba Mars.
10. Sesole le Tšireletso:
LiDAR e bohlokoa haholo mesebetsing ea sesole le ea tšireletso bakeng sa ho hlahloba libaka, ho tsebahatsa sepheo, le tlhahlobo ea sebaka. E thusa ho tsamaea libakeng tse rarahaneng tsa ntoa, ho lemoha litšokelo le ho rera maqiti. Li-drone tse hlomelitsoeng ka LiDAR li etsa mesebetsi e nepahetseng ea ho hlahloba libaka, li fana ka bohlale ba bohlokoa.
