2. Daim Ntawv Qhia Txog Chaw Taws Teeb
LiDAR txhim kho qhov tseeb thiab kev ua haujlwm ntawm daim phiaj xwm av. Siv los ntawm cov dav hlau lossis satellites, nws tau sau cov ntaub ntawv saum toj kawg nkaus hauv thaj chaw loj. Cov ntaub ntawv no yog qhov tseem ceeb rau kev npaj hauv nroog, kev soj ntsuam kev pheej hmoo dej nyab, thiab kev tsim qauv kev thauj mus los. LiDAR pab cov kws tshaj lij hauv kev txheeb xyuas cov kev sib tw hauv av thaum npaj txoj kev loj tshiab, ua rau cov kev uas txo cov kev cuam tshuam ib puag ncig thiab txhim kho kev tsim kho kom zoo. Tsis tas li ntawd, LiDAR tuaj yeem nthuav tawm cov yam ntxwv zais cia hauv qab cov nroj tsuag, ua pov thawj tsis muaj txiaj ntsig hauv kev tshawb fawb archaeological thiab geological.

3. Forestry thiab Agricultural:
Hauv hav zoov, LiDAR yog siv los ntsuas tsob ntoo qhov siab, qhov ntom ntom, thiab cov yam ntxwv ntawm thaj av, uas yog qhov tseem ceeb rau kev tswj hwm hav zoov thiab kev txuag. LiDAR cov ntaub ntawv tsom xam pab cov kws tshaj lij kwv yees hav zoov biomass, saib xyuas kev noj qab haus huv hauv hav zoov, thiab ntsuas qhov phom sij txaus ntshai. Hauv kev ua liaj ua teb, LiDAR txhawb nqa cov neeg ua liaj ua teb hauv kev saib xyuas cov qoob loo loj hlob thiab av noo, ua kom cov dej ua kom zoo dua qub, thiab txhim kho cov qoob loo.
4. Distributed Temperature Sensing:
LiDAR yog qhov tseem ceeb tshwj xeeb hauv kev ntsuas qhov kub thiab txias, ib qho tseem ceeb hauv kev tsim khoom loj lossis cov kab xa hluav taws xob. CovDTS LiDARremotely saib xyuas qhov kub thiab txias, txheeb xyuas qhov muaj peev xwm hotspots los tiv thaiv kev ua txhaum lossis hluav taws kub, yog li ua kom muaj kev nyab xeeb ntawm kev lag luam thiab txhim kho kev siv hluav taws xob.
5. Kev tshawb fawb thiab kev tiv thaiv ib puag ncig:
LiDAR ua lub luag haujlwm tseem ceeb hauv kev tshawb fawb ib puag ncig thiab kev txuag nyiaj. Nws yog siv los saib xyuas thiab txheeb xyuas cov xwm txheej xws li dej hiav txwv nce siab, glacier melting, thiab deforestation. Cov kws tshawb nrhiav siv LiDAR cov ntaub ntawv txhawm rau taug qab cov dej ntws tawm ntawm cov dej khov thiab ntsuas qhov cuam tshuam ntawm kev hloov pauv huab cua ntawm ecosystems. LiDAR tseem saib xyuas cov huab cua zoo hauv nroog thiab kev ua liaj ua teb, ua rau muaj txiaj ntsig zoo rau kev tsim cov cai ib puag ncig.
6. Nroog Planning thiab Management:
LiDAR yog cov cuab yeej muaj zog hauv kev npaj thiab tswj nroog. Kev sau cov ntaub ntawv 3D daws teeb meem siab tso cai rau cov neeg npaj kom nkag siab zoo dua hauv nroog spatial cov qauv, pab txhim kho thaj chaw tshiab, chaw lag luam, thiab cov chaw pej xeem. LiDAR cov ntaub ntawv yog qhov tseem ceeb hauv kev txhim kho cov kev thauj mus los rau pej xeem, ntsuas qhov cuam tshuam ntawm kev tsim kho tshiab hauv nroog, thiab ntsuas kev puas tsuaj hauv vaj tse tom qab muaj kev puas tsuaj.
