I-LiDAR Yamahlathi: Ukulinganisa Umthamo Wemithi Ngokuchanekileyo
Ukuqikelela ukuba ingakanani iplanga ekwihlathi ngokwesiko kwakufuna ukuthumela abasebenzi ukuya kulinganisa isampulu yemithi embalwa uze uqikelele ngehlathi lonke. I-Drone LiDAR ithatha indawo yolo qikelelo lwesampulu ngemodeli epheleleyo yokuphakama komthi (Canopy Height Model) equka wonke umthi kwindawo ehloliweyo.
Ngokubamba ukuphakama komhlaba kunye nentloko yomthi kuyo yonke indawo, i-LiDAR ibala ukuphakama komthi ngokuthe ngqo. Oku kuphakama kudityaniswe nendawo yesiciko kunika oongcali bamahlathi isiseko esomeleleyo sokuqikelela umthamo wamaplanga kunye ne-biomass kwihlathi liphela.

Indlela OkuSebenza Ngayo Uqikelelo Lomthamo nge-LiDAR
Ukwakhiwa kwemodeli yomhlaba yedijithali (DTM)
Ukuhlelwa kwamanqaku omhlaba kuvelisa imodeli yomhlaba oze phantsi kwemithi.
Ukwakhiwa kwemodeli yobuso bedijithali (DSM)
Iimpendulo ze-laser eziphezulu kwindawo nganye zenza imodeli emele phezulu kwesiciko sehlathi.
Ukubalwa kwemodeli yokuphakama kwesiciko (CHM)
Ukususa ukuphakama komhlaba ekuphakameni kobuso bemithi kunika ukuphakama komthi okuchanekileyo.
Ukwahlulwa komthi ngamnye (Segmentation)
I-algorithms ichonga iintloko zemithi nganye ngaphakathi kwe-CHM kuhlalutyo lomthi ngamnye.
Uqikelelo lomthamo kunye ne-biomass
Ukuphakama, indawo yesiciko, kunye nee-equations ze-allometric zidityaniswa ukuqikelela umthamo opheleleyo.
Kuba i-LiDAR ibamba lonke ihlathi endaweni yesampulu encinci, uqikelelo lomthamo luthathela ingqalelo ukuhluka kwemvelo kuyo yonke indawo, kubandakanywa izikhewu, iindawo ezixineneyo, kunye nemiphetho yehlathi.
Isampulu yebala ikuxelela ngemithi embalwa kuphela. I-LiDAR ikuxelela ngomthi ngamnye kwihlathi lonke.
Ukusebenzisa Oku Kwizicwangciso Zamahlathi
Nokuba kukubala amaplanga okurhweba, ukuhlola i-carbon egciniweyo, okanye ulawulo lwamasimi emithi, ukugubungela okupheleleyo kwesiciko kutshintsha amathuba ohlalutyo lwamahlathi. Iqela lethu le-drone survey libonelela ngeemodeli zokuphakama kwesiciko ezisuka kwidatha ye-LiDAR scan eyenzelwe abathengi bezamahlathi.
Ingaba ufuna uvavanyo lomthamo wehlathi okanye i-biomass?
Sixelele ngendawo yakho kunye neentlobo zemithi onayo, kwaye siza kucacisa indlela yethu esekelwe kwi-LiDAR.
Imibuzo Ebuzwa Rhoqo
I-LiDAR ibala ukuphakama komthi ngokususa ukuphakama komhlaba ekuphakameni kwentloko yomthi kwindawo nganye.
Yidatha emele ukuphakama komthi kuyo yonke indawo ehlathini, ebalwe kusuka kwiimodeli zomhlaba kunye nobuso be-LiDAR.
I-LiDAR ibamba lonke ihlathi endaweni yesampulu encinci, ibonelela ngoqikelelo oluchanekileyo olubandakanya konke ukuhluka.
Ewe, ii-algorithms zokwahlula zinokuchonga iintloko zemithi nganye kwi-CHM ukuze kuhlalutywe umthi ngamnye.
Lulwalamano lwezibalo phakathi kokuphakama komthi, indawo yesiciko, kunye nomthamo wamaplanga ukuguqula idatha ye-LiDAR ibe ngumthamo.
Ewe, uqikelelo lwe-biomass oluvela kwidatha ye-LiDAR lusetyenziswa kakhulu kwiinkqubo zokuhlola nokubeka iliso kwi-carbon.
Ewe, iyasebenza kuzo zombini, nangona ukulungelelaniswa kwamahlathi atyaliweyo kwenza uhlalutyo lube lula.
Kuxhomekeke kumandla e-drone kunye nesicwangciso senqwelo-moya, kodwa inokuhlola ukusuka kumhlaba omncinci ukuya kwizidiliya ezinkulu.
Uvavanyo olulinganiselweyo emhlabeni ngemithi embalwa lunceda ukulungelelanisa nokungqinisisa ii-equations ze-allometric.
Ukungaqheleki kwesakhiwo sesiciko esibonakala kwi-LiDAR kungabonisa uxinzelelo okanye izifo, zikhatshwa zizinzwa ze-multispectral.
Le nombolo ibekelwe imibuzo yeeprojekthi kuphela. Nceda ungatsaleli uncedo loqeqesho okanye imisebenzi.
