3. Ezamahlathi nezoLimo:
Kumahlathi, i-LiDAR isetyenziselwa ukulinganisa ubude bomthi, ukuxinana, kunye neempawu zomhlaba, eziyimfuneko kulawulo nokugcinwa kwehlathi.Uhlalutyo lwedatha ye-LiDAR lunceda iingcali ukuba ziqikelele i-biomass yehlathi, ukubeka iliso kwimpilo yehlathi, kunye nokuvavanya ingozi yomlilo.Kwezolimo, i-LiDAR ixhasa amafama ekubekeni iliso ukukhula kwezityalo kunye nokufuma komhlaba, ukwandisa iindlela zokunkcenkceshela, kunye nokuphucula izivuno zezityalo.
4. UVavanyo loBubushushu obusasaziweyo:
I-LiDAR ibaluleke kakhulu ekuboneni ubushushu obusasazwayo, into ebalulekileyo ekusetweni kwamashishini amakhulu okanye kwiintambo zothumelo lwamandla.IDTS LiDARijonga kude ukusasazwa kobushushu, ichonge iindawo ezinokubakho ukunqanda iziphene okanye imililo, ngokwenjenjalo iqinisekisa ukhuseleko lwamashishini kunye nokuphucula ukusebenza kakuhle kwamandla.
5. UPhando nokuKhuselwa kokusiNgqongileyo:
I-LiDAR idlala indima ebalulekileyo kuphando lwendalo esingqongileyo kunye neenzame zolondolozo.Isetyenziselwa ukubeka esweni kunye nokuhlalutya iziganeko ezifana nokunyuka komphakamo wolwandle, ukunyibilika komkhenkce, kunye nokutshatyalaliswa kwamahlathi.Abaphandi basebenzisa idatha ye-LiDAR ukulandelela amazinga okubuya komkhenkce kunye nokuvavanya iimpembelelo zokutshintsha kwemozulu kwi-ecosystems.I-LiDAR ikwabeka iliso kubulunga bomoya kwiindawo zasezidolophini nakwizolimo, inegalelo kuphuhliso lwemigaqo-nkqubo esebenzayo yokusingqongileyo.
