Te Āwhina a te Hangarau 3D ki te Aroturuki Ngāhere
Ko ngā ngahere tētahi o ngā pou matua o te ora o te Ao. Kei roto i ēnei ngā momo koiora, e pupuri ana i te huringa wai, e pupuri ana i te waro, ā, e whakarato ana i te oranga mō ngā hapori maha. Heoi anō, he ngoikore hoki ngā ngahere ki ngā tūmomo mōrearea: te whakangaromanga o ngā ngahere, ngā ahi, te toki rakau ture kore, te keri whenua ture kore, me ngā pānga o te huringa āhuarangi. I waenganui i ēnei āhuatanga, he mea nui te aroturuki tika me te tere o ngā ngahere. Ko tētahi putanga hou e whakamahia nuitia ana ko te hangarau 3D—he huarahi mahere me te tātari e taea ai te whakaatu i te hanganga ngahere kia tino pono ake i ngā mahere rua-ahu tuku iho.
He aha te hangarau 3D i roto i te aroturukitanga ngahere?
Ko te hangarau 3D i roto i te horopaki o te ngahere e uru ana ki te whakamahinga o ngā raraunga e hopu ana i te āhua me te hanganga ā-wāhi: te teitei o te rākau, te kiato o te karauna, te pikinga o te pari, tae atu ki ngā āhua o te mata o te whenua. He rerekē ki ngā whakaahua amiorangi 2D, e aro nui ana ki ngā mōhiohio "mai i runga" (ngā tauira tae me te kakano), mā te whakatauira 3D ka taea e tātou te kite i te "rahinga" me ngā "paparanga" o te ngahere. He mea nui tēnei nā te mea he maha ngā mōhiohio taiao—pērā i te koiora, ngā putunga waro, me te hauora o te tūnga—e hono tata ana ki te hanganga poutū.
I te nuinga o te wā, ka ahu mai te hangarau ngahere 3D i ētahi tikanga: LiDAR (Light Detection and Ranging), te whakaahua mai i ngā waka rererangi, i ngā waka rererangi rānei, me ngā tauira teitei mamati mai i ngā amiorangi. Ka taea te tukatuka i ēnei katoa hei whakaaturanga toru-ahu ka taea te tātari e ngā tohunga ngahere, ngā kairangahau, ngā āpiha kāwanatanga, me ngā kamupene whai whakaaetanga whakahaere ngahere.
LiDAR: "hihi-X" o te hanganga o te ngahere
Ko tētahi o ngā hangarau tino kaha mō te aroturuki ngahere ko te LiDAR. Ko te tikanga, ka tukuna e te pūoko LiDAR ngā pao reera ki te mata o te whenua. Ka hoki atu ēnei pao ki te pūoko, ā, ka tatauhia te tawhiti mai i tō rātou wā haere. Nā te mea ka taea e ngā pao reera te uru ki ngā āputa o te tuanui, ka taea e te LiDAR te hopu i ngā whakaata maha i te wā kotahi: mai i ngā pito rau, ngā manga, ngā otaota o raro, tae noa ki te whenua.
Ko te hua he kapua pūwāhi—he kohinga o ngā miriona pūwāhi 3D e whakaatu ana i ngā tipu me te āhua o te whenua. Mai i ēnei raraunga, ka taea e ngā kaitātari te waihanga i ngā tauira teitei o te tuanui, te mahere i te kiato o te tuanui, te tautuhi i ngā āputa ngahere, tae atu ki te whakatau tata i te rahinga o ngā tūnga. Ki te whakatauritea ki ngā rangahau mara e whakawhirinaki ana ki ngā kauwhata tauira iti, ka taea e LiDAR te kapi i ngā wāhi whānui me te nui o ngā taipitopito, ka penapena i te wā me te moni i te wā roa.
Te whakaahua ira-kore: he nui ngā taipitopito me te ngāwari
Haunga te LiDAR, he taputapu rongonui ngā waka rererangi iti mō te mahere ngahere. He kāmera kei ngā waka rererangi iti e tango whakaahua taupatupatu ana mai i ngā koki maha. Mā te whakamahi i ngā tikanga whakaahua-ira, ka taea e te pūmanawa te tatau i te hohonu me te hanga tauira mata 3D e kiia nei ko ngā orthomosaics me ngā mata 3D, arā, ngā tauira mata matihiko.
Ko ngā painga o te ine whakaahua ko tōna utu iti iho i te LiDAR, tōna ngāwari ki te whakahaere, me tōna pai mō te aroturuki auau. Ka taea te whakamahi i ngā waka rererangi iti i muri i ngā ahi, ngā waipuke, ngā hau kaha rānei hei mahere tere i ngā kino. I ngā wāhi tiaki taiao, ka āwhina hoki ngā waka rererangi iti ki te aroturuki i ngā āhuatanga o te huarahi tirotiro, ngā huringa o te uhi whenua, me te tuhi i ngā wāhi e ngāwari ana ki te takahi.
Heoi, he iti noa iho ngā ngoikoretanga o te ine whakaahua: ko te nuinga o ngā kāmera ka hopu i te mata o runga (te tuanui), ā, he uaua ki te kite i ngā hanganga o raro, i te mata whenua rānei i roto i ngā ngahere matotoru. Nō reira, i raro i ētahi āhuatanga, ka pai tonu te LiDAR.
Tātaihia te koiora me ngā putunga waro kia tika ake
Ehara i te mea ko te tirotiro ngahere anake te tirotiro mēnā kei "tērā tonu" te ngahere, engari ko te nui o te waro e rongoa ana. Mā te hangarau 3D ka taea te whakatau tata i te koiora nui ake nā te mea e hono ana te koiora nui ki te hanganga o te rākau: te whānui, te teitei, me te rōrahi.
Mā te whakamahi i ngā raraunga 3D, ka taea e ngā tohunga te whakatauira i te whanaungatanga i waenga i te teitei o te tuanui, te mātotoru o ngā tipu, me ngā inenga o te mara, kātahi ka whakanuia ake ki ngā rohe whānui ake. He mea nui tēnei mō ngā kaupapa whakaiti i te huringa āhuarangi pērā i te REDD+, te hokohoko waro, te pūrongo tukunga ā-motu rānei. Mā ngā whakatau tata waro tika ake ka nui ake te pono o te whakamahere kaupapa here me ngā whakatenatena ōhanga mō te tiaki ngahere.
Te kitenga o ngā panoni: ka tere ake te kitea o te toki rakau turekore me te whakangaromanga ngahere
He tino āwhina te whakatauira 3D ki te kimi i ngā panonitanga, arā, ko te whakataurite i ngā āhuatanga o te ngahere i roto i te wā. Mā te whakataurite i ngā kapua pūwāhi LiDAR, i ngā tauira rererangi 3D rānei mai i ngā wā maha, ka taea e ngā kaitātari te kite i ngā panonitanga ngawari kāore pea e kitea wawetia i roto i ngā whakaahua 2D: te ngaronga o ētahi rākau nunui, te hanganga o ngā ara hou, ngā panonitanga rānei o te teitei o te tuanui nā te tapahi rakau kua tohua.
He mea nui tēnei kitenga wawe mā ngā pirihimana. Ina kitea ngā tohu o te poro rakau, o te takahi whenua rānei, ka taea te arahi i ngā tīma o te mara ki ngā wāhi tika, kaua ki te rapu noa i ngā wāhi whānui. Ka hua ake tēnei he tere ake, he whai hua ake hoki te urupare.
Te whakaiti i te ahi ngahere: te mārama ki ngā "wahie" i runga i te whenua
He maha ngā wā ka pāngia ngā ahi ngahere e te nui me te horapa o ngā otaota maroke e mahi ana hei wahie. Mā ngā raraunga 3D ka āwhina i te mahere i te hanganga o ngā otaota: ngā wāhi he matotoru ngā ngahere, ngā kohinga o te koiora maroke, me ngā pikinga pari ka taea te whakatere i te horapa o te ahi.
Mā ngā tauira 3D, ka taea e ngā kaiwhakahaere te hoahoa i ngā rautaki ārai—pērā i te hanga ārai ahi , ngā ara uru atu ki te tinei ahi, te whakahaere wahie rānei i ngā wāhi whakaraerae. Whai muri i te puta o te ahi, ka taea hoki e ngā waka rererangi kore-rangi me te LiDAR te mahere i te whānuitanga o te kino, hei āwhina i te whakaora i te pūnaha rauropi me te aromatawai kaupapa here.
Te tautoko i te tiaki i ngā kararehe mohoao me ō rātou kāinga noho
He maha ngā kararehe mohoao e whakawhirinaki ana ki ngā hanganga ngahere motuhake: ko ētahi e hiahia ana ki ngā rākau teitei hei kōhanga, ko ētahi e hiahia ana ki tētahi papa raro matotoru hei piringa. Mā te hangarau 3D ka taea e ngā kairangahau te mahere i ngā āhuatanga o te nohonga pēnei i te teitei o te tuanui, te uaua poutū, me te hononga tuanui. Mā ēnei raraunga ka āwhina i te tautuhi i ngā rohe matua, ngā ara o ngā kararehe mohoao, me ngā wāhi e tino hiahia ana kia whakahokia mai.
Hei tauira, ehara i te mea me whai "ara matomato" i runga i te mapi 2-ahu anake te ara mō ngā kararehe mohoao, engari me whai hanganga tuanui hoki e taea ai e ngā kararehe mohoao o te rākau te neke. Mā te tātaritanga 3-ahu ka taea te whakarato i tētahi pikitia pono ake o ēnei hononga.
Te whakaurunga ki te AI me te GIS: mai i ngā raraunga mata ki ngā whakataunga
He nui rawa, he uaua hoki ngā raraunga 3D. Koinei te wāhi e whai wāhi nui ai te GIS (Ngā Pūnaha Mōhiohio Whenua) me te matauranga horihori (AI). Ka taea e te AI te āwhina i te whakarōpū i ngā momo uhi whenua, te tautuhi i ngā tauira tapahi rakau, tae atu ki te matapae i ngā wāhi e mōrearea ana ki te huringa.
Ina whakauruhia ngā raraunga 3D ki roto i tētahi pūnaha GIS, ka taea e ngā kaihanga kaupapa here te tiro i ngā mapi taunekeneke: ngā wāhi e puta ai ngā huringa, ngā kauwhata ia au, me ngā kaupapa matua o te mahi. Ka tautokohia e tēnei te whakahaere ngahere e ahu mai ana i ngā taunakitanga, ehara i te mea ko ngā whakapae anake.
Ngā wero o te whakatinanatanga o te hangarau 3D
Ahakoa tōna pūmanawa, kei te pāngia anō hoki te aroturuki ngahere e ahu mai ana i te 3D e ngā wero. Tuatahi, ka nui pea te utu o ngā taputapu me te tukatuka raraunga, inā koa mō te LiDAR. Tuarua, me whai kaimahi mohio e kaha ana ki te tukatuka kapua tohu, te whakaahua, me te whakamaori hua. Tuatoru, he raruraru kei roto i ngā whakaaetanga rere waka rererangi me te haumarutanga raraunga i ngā wāhi tairongo. Hei tāpiri, ko ngā āhuatanga o te rangi pārūrū—ngā kapua matotoru, te ua, me te haumākū nui—ka pā ki te kohikohinga raraunga, inā koa mō ngā whakaahua whatu.
Heoi, i te whanaketanga haere o te hangarau, kua tīmata te memeha haere o ēnei arai. Kei te piki haere te utu mō ngā taputapu, kei te ngāwari ake te whakamahi i ngā pūmanawa, ā, kei te whānui haere te mahi tahi a te kāwanatanga, te ao mātauranga, me te hapori.
Whakamutunga
Mā te hangarau 3D ka whakaratohia he huarahi hou ki te "tiro" i ngā ngahere: ehara i te mea he whānui matomato noa iho mai i runga, engari he hanganga uaua me te teitei, te rahinga, me ngā paparanga. Mā te LiDAR, te whakaahua-ā-ringa, me te whakaurunga o te AI me te GIS, ka tika ake, ka tere ake, ka whai kōrero ake hoki te aroturukitanga ngahere. He whānui ngā painga—mai i te aroturuki i te whakangaromanga ngahere me te tatau i ngā putunga waro ki te whakaiti i te ahi me te tiaki i ngā nohoanga kararehe mohoao.
I waenganui i te pikinga o te pēhanga ki ngā ngahere, ehara te hangarau 3D i te taputapu papai noa iho, engari he wāhanga nui o te rautaki mō te tiaki i ngā rauropi. Ina tutuki ngā raraunga pai ki ngā kaupapa here tika me te whai wāhi a te hapori, ka nui ake te kitea, te ine, me te whai hua o te whai wāhitanga ki te tiaki i ngā ngahere.
Ki te hiahia koe, ka taea e au te whakarerekē i tēnei tuhinga mō te horopaki o Initonīhia (hei tauira, ngā ngahere tāmi, ngā wāhi tiaki taiao, ngā kaupapa waro rānei), tāpirihia he rangahau take, hangaia rānei he putanga rongonui ake mō ngā kaipānui whānui/ngā tamariki kura.
