Indlela Ubuchwepheshe be-3D Obusiza Ngayo Ukuqapha Amahlathi
Amahlathi angenye yezinsika eziyinhloko zokuphila eMhlabeni. Agcina ukuhlukahluka kwezinto eziphilayo, agcina umjikelezo wamanzi, aqongelela ikhabhoni, futhi ahlinzeka ngempilo yemiphakathi eminingi. Kodwa-ke, amahlathi nawo asengozini yokusongelwa: ukugawulwa kwamahlathi, imililo, ukugawulwa kwemithi okungekho emthethweni, ukumbiwa kwemigodi okungekho emthethweni, kanye nemiphumela yokushintsha kwesimo sezulu. Phakathi kwalezi zimo, ukuqapha amahlathi okunembile nokusheshayo kuyisidingo esiphuthumayo. Enye intuthuko esetshenziswa kakhulu ubuchwepheshe be-3D—indlela yokumapha nokuhlaziya engabonisa isakhiwo samahlathi ngendlela engokoqobo kunemamephu endabuko anezinhlangothi ezimbili.
Buyini ubuchwepheshe be-3D ekuqapheni amahlathi?
Ubuchwepheshe be-3D kumongo wezolimo lwamahlathi buhilela ukusetshenziswa kwedatha ebamba isimo sendawo kanye nesakhiwo: ukuphakama kwesihlahla, ukuminyana komqhele, ukuthambekela kwemithambeka, kanye nemidwebo yomphezulu womhlaba. Ngokungafani nesithombe sesathelayithi se-2D, esigcizelela ulwazi "oluvela phezulu" (amaphethini ombala nokuthungwa), ukumodela kwe-3D kusenza sibone "ivolumu" kanye "nezendlalelo" zehlathi. Lokhu kubalulekile ngoba ulwazi oluningi lwezemvelo - njenge-biomass, amasheya e-carbon, kanye nempilo ye-stand - luhlobene eduze nesakhiwo esiqondile.
Ngokuvamile, ubuchwepheshe behlathi le-3D butholakala ngezindlela eziningana: i-LiDAR (Ukutholwa Kokukhanya Nokukala), i-photogrammetry evela kuma-drones noma ezindizeni, kanye namamodeli okuphakama kwedijithali avela kumasathelayithi. Konke lokhu kungacutshungulwa kube izethulo ezinezinhlangothi ezintathu ezingahlaziywa ochwepheshe bamahlathi, abacwaningi, izikhulu zikahulumeni, kanye nezinkampani ezinezimvume zokuphathwa kwamahlathi.
I-LiDAR: "i-x-ray" yesakhiwo sehlathi
Enye yezindlela zobuchwepheshe ezinamandla kakhulu zokuqapha amahlathi yi-LiDAR. Empeleni, inzwa ye-LiDAR ikhipha ama-laser pulse aye ebusweni bomhlaba. Lawa ma-pulse abuyela emuva kunzwa, futhi ibanga libalwa kusukela esikhathini sawo sokuhamba. Ngenxa yokuthi ama-laser pulse angangena ezikhaleni ze-canopy, i-LiDAR ingaqopha ukubonakaliswa okuningi ngasikhathi sinye: kusukela ezihlokweni zamaqabunga, amagatsha, izimila ezingaphansi komhlaba, ngisho nomhlabathi.
Umphumela uba yifu eliyiphuzu—iqoqo lezigidi zamaphuzu e-3D abonisa izitshalo kanye ne-topography. Kusukela kulolu lwazi, abahlaziyi bangakha amamodeli okuphakama kwe-canopy, bamephe ubuningi be-canopy, bathole izikhala zamahlathi, futhi balinganisele nomthamo wokuma. Uma kuqhathaniswa nokuhlolwa kwensimu okuncike ezizathwini zesampula ezilinganiselwe, i-LiDAR ingamboza izindawo ezinkulu ngemininingwane ephezulu, isindise isikhathi nemali ngokuhamba kwesikhathi.
I-photogrammetry yedrone: imininingwane ephezulu kanye nokuguquguquka
Ngaphezu kwe-LiDAR, ama-drone manje aseyithuluzi elidumile lokumapha amahlathi. Ama-drone aphatha amakhamera athatha izithombe ezihambisanayo kusuka kuma-engeli amaningi. Ngokusebenzisa amasu e-photogrammetry, isofthiwe ingabala ukujula futhi yakhe amamodeli wobuso be-3D abizwa ngokuthi ama-orthomosaics nama-meshes e-3D, noma amamodeli wobuso bedijithali.
Izinzuzo ze-photogrammetry ukuthi izindleko zayo ziphansi uma kuqhathaniswa ne-LiDAR, ukuguquguquka kwayo kokusebenza, kanye nokufaneleka kwayo ukuqapha okuvamile. Ama-drone angafakwa ngemuva kwemililo, izikhukhula, noma imimoya enamandla ukuze kuhlolwe umonakalo ngokushesha. Ezindaweni zokulondolozwa kwemvelo, ama-drone asiza futhi ukuqapha izimo zendlela yokuqapha, izinguquko zembozo zomhlaba, kanye nokubhala phansi izindawo ezivame ukungenela.
Kodwa-ke, i-photogrammetry inemikhawulo: amakhamera athwebula ngokuyinhloko indawo engaphezulu (i-canopy), okwenza kube nzima ukubona izakhiwo ezingaphansi komhlaba noma indawo yomhlabathi emahlathini aminyene. Ngakho-ke, ngaphansi kwezimo ezithile, i-LiDAR ihlala ingcono kakhulu.
Bala amasheya e-biomass kanye ne-carbon ngokunembe kakhudlwana
Ukuqapha amahlathi akukhona nje ukubona ukuthi ihlathi "lisekhona," kodwa futhi nokuthi ligcina ikhabhoni engakanani. Ubuchwepheshe be-3D buvumela ukulinganisa okuqinile kwe-biomass ngoba i-biomass ihlobene nesakhiwo sesihlahla: ububanzi, ukuphakama, kanye nomthamo.
Ngedatha ye-3D, ochwepheshe bangalinganisa ubudlelwano phakathi kokuphakama kwekhanophi, ukuminyana kwezitshalo, kanye nokulinganiswa kwensimu, bese bekukhulisa kuze kufike ezindaweni ezinkulu. Lokhu kubalulekile ezinhlelweni zokunciphisa ukuguquka kwesimo sezulu njenge-REDD+, ukuhweba ngekhabhoni, noma ukubika ukukhishwa kwegesi kuzwelonke. Izilinganiso zekhabhoni ezinembile kakhulu zenza ukuhlela inqubomgomo kanye nezikhuthazo zomnotho zokulondolozwa kwamahlathi kube okuthembekile kakhudlwana.
Ukutholwa koshintsho: ukugawulwa kwemithi okungekho emthethweni kanye nokugawulwa kwamahlathi kutholakala ngokushesha okukhulu
Ukumodela kwe-3D kuyasiza kakhulu ekuboneni ushintsho, okuhlanganisa ukuqhathanisa izimo zehlathi ngokuhamba kwesikhathi. Ngokuqhathanisa amafu e-LiDAR point noma amamodeli e-3D drone avela ezikhathini eziningi, abahlaziyi bangathola izinguquko ezicashile ezingase zingabonakali kalula esithombeni se-2D: ukulahlekelwa kwezihlahla eziningana ezinkulu, ukudalwa kwemizila emisha, noma izinguquko ekuphakameni kwekhanophi ngenxa yokugawulwa kwemithi okukhethiwe.
Lokhu kutholakala kusenesikhathi kubalulekile ekuphoqelelweni komthetho. Uma kutholakala izinkomba zokungena kwemithi noma ukungena kwezindawo, amaqembu asensimini angaqondiswa ezindaweni ezifanele, kunokuba afune izindawo ezinkulu ngokungahleliwe. Lokhu kuphumela empendulweni esheshayo nephumelelayo.
Ukunciphisa umlilo emahlathini: ukuqonda "izinto zokubasa" ezisemhlabeni
Imililo yamahlathi ivame ukuthonywa inani kanye nokusabalala kwezitshalo ezomile ezisebenza njengophethiloli. Idatha ye-3D isiza ukudweba ukwakheka kwezitshalo: izindawo ezinezimila eziminyene, ukuqongelela kwe-biomass eyomile, kanye ne-slope gradients engasheshisa ukusabalala komlilo.
Ngamamodeli e-3D, abaphathi bangakha amasu okuvimbela—njengokwakha izivimbeli zomlilo, imizila yokufinyelela ekulweni nomlilo, noma ukuphatha uphethiloli ezindaweni ezisengozini. Ngemva komlilo, ama-drones kanye ne-LiDAR bangakwazi futhi ukukala izinga lomonakalo, basize ekubuyiselweni kwemvelo kanye nokuhlolwa kwenqubomgomo.
Ukusekela ukulondolozwa kwezilwane zasendle kanye nezindawo zazo zokuhlala
Izilwane eziningi zasendle zincike ezakhiweni ezithile zehlathi: ezinye zidinga imithi emide ukuze zakhele izidleke, ezinye zidinga indawo engaphansi komhlaba ebanzi ukuze zithole indawo yokukhosela. Ubuchwepheshe be-3D buvumela abacwaningi ukuthi badwebe izici zendawo yokuhlala njengokuphakama kwekhava, ubunzima obuqondile, kanye nokuxhumana kwekhava. Lolu lwazi lusiza ekuboneni izindawo eziyinhloko, imihubhe yezilwane zasendle, kanye nezindawo ezidinga kakhulu ukulungiswa.
Isibonelo, umzila wezilwane zasendle awudingi nje kuphela "umgwaqo oluhlaza" kumephu ye-2D, kodwa futhi nesakhiwo somphetho esivumela izilwane zasendle ezihlala ezihlahleni ukuthi zihambe. Ukuhlaziywa kwe-3D kunganikeza isithombe esingokoqobo salokhu kuxhumana.
Ukuhlanganiswa ne-AI kanye ne-GIS: kusukela kudatha eluhlaza kuya ezinqumweni
Idatha ye-3D ngokuvamile inkulu kakhulu futhi iyinkimbinkimbi. Yilapho i-GIS (Izinhlelo Zolwazi Lwendawo) kanye nobuhlakani bokwenziwa (i-AI) kudlala khona indima ebalulekile. I-AI ingasiza ekuhlukaniseni izinhlobo zesembozo somhlaba, ithole amaphethini okuloba, futhi ibikezele nezindawo ezisengozini yokushintsha.
Uma idatha ye-3D ihlanganiswa ohlelweni lwe-GIS, abenzi bezinqubomgomo bangabuka amamephu asebenzisanayo: izindawo zoshintsho, amagrafu ezitayela, kanye nezinto eziza kuqala esenzweni. Lokhu kusekela ukuphathwa kwamahlathi okusekelwe ebufakazini, hhayi nje izibikezelo.
Izinselele zokusebenzisa ubuchwepheshe be-3D
Naphezu kwesithembiso sayo, ukuqapha amahlathi okusekelwe ku-3D nakho kubhekene nezinselele. Okokuqala, izindleko zemishini kanye nokucubungula idatha zingaba phezulu, ikakhulukazi kwi-LiDAR. Okwesibili, kudinga abasebenzi abanekhono abakwaziyo ukucubungula amafu ephuzu, i-photogrammetry, kanye nokuhumusha imiphumela. Okwesithathu, kunezinkinga ngezimvume zokundiza ze-drone kanye nokuphepha kwedatha ezindaweni ezibucayi. Ngaphezu kwalokho, izimo zezulu zasezindaweni ezishisayo—amafu aminyene, imvula, kanye nomswakama ophezulu—kungathinta ukuqoqwa kwedatha, ikakhulukazi yezithombe ezibonakalayo.
Kodwa-ke, njengoba ubuchwepheshe buthuthuka, eziningi zalezi zithiyo ziyaqala ukuncipha. Amadivayisi aya ngokuya ethengeka, isofthiwe iya ngokuya isebenziseka kalula, futhi ukubambisana phakathi kukahulumeni, izazi zemfundo ephakeme, kanye nomphakathi kuyakhula.
Isiphetho
Ubuchwepheshe be-3D buhlinzeka ngendlela entsha "yokubona" amahlathi: hhayi nje njengobubanzi obuluhlaza obuvela phezulu, kodwa njengezakhiwo eziyinkimbinkimbi ezinokuphakama, ivolumu, kanye nezendlalelo. Nge-LiDAR, i-drone photogrammetry, kanye nokuhlanganiswa kwe-AI kanye ne-GIS, ukuqapha amahlathi kuba nenembile, kusheshe, futhi kube nolwazi oluningi. Izinzuzo zisabalele—kusukela ekulandeleni ukugawulwa kwamahlathi kanye nokubala amasheya ekhabhoni kuya ekunciphiseni umlilo kanye nokulondolozwa kwezindawo zokuhlala zasendle.
Phakathi kokucindezeleka okwandayo emahlathini, ubuchwepheshe be-3D abuyona nje ithuluzi elimangalisayo, kodwa buyingxenye ebalulekile yesu lokulondoloza imvelo. Lapho idatha enhle ihlangabezana nezinqubomgomo ezinengqondo kanye nokubandakanyeka komphakathi, ithuba lokulondoloza amahlathi liba yinto ebonakalayo, elinganiswayo, futhi ephumelela kakhulu.
Uma ufisa, ngingayivumelanisa le ndatshana nomongo wase-Indonesia (isib. amahlathi e-peat, izindawo zokulondolozwa kwemvelo, noma izinhlelo ze-carbon), ngingeze izifundo zamacala, noma ngenze inguqulo ethandwa kakhulu yabafundi abavamile/izingane zesikole.
