Kuzivikanwa uye kugona kweUnmanned Aerial Vehicles (UAVs) kwabatsira maindasitiri mazhinji nekudzikisa mitengo uye kuwedzera kuchengetedzwa kwevashandi. Asi zvakadini nenzanga yesayenzi? Mazana, kana asiri zviuru, zvesainzi akazvimiririra nemayunivhesiti pasi rose anoshandisa maUAV aya kuita ongororo dzakaoma dzesainzi nenzira itsva.
Isu tinowanzo kutarisa nezve maindasitiri uye ekutengesa maUAV, asi sainzi yakachena inobatsirwawo kubva mukukwanisa uye kuwanikwa kwendege kana mabhajeti akaomerwa uye nguva yekupedzisa kuyedza yakakosha.
Semuyenzaniso, masayendisiti akati wandei echiPolish akabatana pakuongorora kwakadzama kwekukukurwa kwemahombekombe, vachishandisa matekinoroji akati wandei akadai semumhepo LiDAR uye bathymetry.
Pawel Tysiac naRafal Ossowski veFaculty of Civil and Environmental Engineering paGdansk University of Technology, vachibatsirana naLukasz Janowski weMaritime Academy yeMaritime University yeGdynia naDamian Moskalewicz weDhipatimendi reGeomorphology neQuaternary Geology paFaculty of Oceanography neGeography, vakaita chidzidzo cheUniversity of Gdansk of comprohensive kudzidza. chikamu chemahombekombe ePoland (kunyanya kunyanya, 1-mamaira yakatambanudzwa yekumaodzanyemba kweBaltic Sea).
Pepa racho rine musoro wekuti "Ongororo yekuparara kwemawere emahombekombe uchishandisa drone uye orthophoto data uye bathymetric LiDAR muGoogle Earth Injini". Yakabudiswa muScientific Reports, Ndira 2025 uye muenzaniso wakanaka wekushandiswa kwehunyanzvi hutsva kuunganidza data rakakosha kunzwisisa nzira idzo zvisikwa zvinoshandura geography.
Takava nemukana wekutaura naPawel Tysiac, mumwe wevanyori vechidzidzo, kuti tinzwisise zviri nani kukanganisa kwedrones neLiDAR pachirongwa chavo.
“Nzira dzechinyakare dzekutarisa kukukurwa kwemawere dzinowanzoda kushanda nesimba mumunda uye maverengero akaomarara ekugovewa kwenzvimbo pachishandiswa nzira dzekare dzekuongorora ivhu,” akadaro Pawel. "Mukupesana, kufambira mberi kwazvino mukunzwa kure uye kudzidza muchina kunopa nzira nyowani dzekuongorora kuparara kwemawere nekubudirira kukuru uye nemazvo."
Kuparara kwemahombekombe kwakwezva kutarisisa kwehurumende nemasaenzi pasirese sezvo huwandu hwenjodzi dzinongoitika dzoga huchiwedzera uye njodzi yega yega inokonzera kukuvadza kwakawanda kwevanhu uye nharaunda.
"Mubepa rino, tinoshandisa izwi rokuti 'bluff degradation' zvakanyanya. Tinoritsanangura sechikonzero chekupedzisira chekuchinja kwemawere emahombekombe egungwa anokonzerwa nezvinhu zvakasiyana-siyana uye maitiro, kusanganisira yakaoma lithologic uye hydrogeologic nharaunda, dutu remhepo rinoputika basa, kunaya kwemvura, kuvhuvhuta kwemhepo, uye mabasa evanhu anotungamirira mukuvandudzika kwehukuru-hukuru, mafambiro, mafambiro, uye mafambiro. nemarara,” akadaro Pawel. "Kubva pane izvi, nheyo inokosha yekudzidza iyi ndeyokuti magetsi emagetsi emagetsi emagetsi anosiyana-siyana munzvimbo dzakakanganiswa nekuparara. Mumamiriro ezvinhu egungwa bluffs, kuchinja kwekuunganidza zvinhu, zvinomera uye zvimwe zvinhu zvinogona kutungamirira kukusiyana kukuru. "
Nhasi, kuona kure ndiyo nzira yakajairwa yekutarisa nharaunda dzemahombekombe. Nekushandisa marudzi akasiyana-siyana emifananidzo uye data yakaunganidzwa kubva kumasetellite, mapuratifomu emhepo, uye pasi-based sensors, vatsvakurudzi vanogona kuwana ruzivo rwakadzama uye rwemazuva ano nezvenzvimbo dzemahombekombe. Kugadziriswa panguva yakakodzera furemu mifananidzo inobvumira kucherechedzwa kwekuchinja kwemahombekombe morphology nekufamba kwenguva uye kubatsira kuona nzvimbo dzakanyanya kubatwa nenjodzi dzinongoitika dzoga. Muchiitiko ichi, vanyori vakashandisa mapikicha emuchadenga, ayo anopa mifananidzo yepamusoro-soro inobatsira kune tsanangudzo isati yasvika-uye-mushure mekuenzanisa. Zvisinei, pane dambudziko renguva dzakasiyana dzekuvhenekera pamifananidzo, zvichiita kuti zvinhu zvakasiyana zvigadziriswe. Panyaya yephotogrammetry, ndege dzinoda kuitiswa pasi pemamiriro akafanana, asi pachine dzimwe nyaya nekusiyana kwemwaka mune izvi.
"Takasarudza kushandisa LiDAR seimwe nzira yekugadzirisa nekuchinja kwemwenje," anodaro Pawel. "Data yeLiDAR inokosha pakuyera kushanduka kwemahombekombe egungwa nepamusoro-soro, zvichibatsira kusefa data kubva kune zvinomera kana nzvimbo dzakatsaurwa. Chigadzirwa chinonyanya kukosha cheLiDAR ndiyo Digital Elevation Model (DEM), iyo inoshandiswa kugadzira 3D inomiririra nzvimbo yegungwa. Iyi mienzaniso inobatsira kunzwisisa kugoverwa kwepakati kwekuparara kwevhu kuburikidza nekuverenga mienzaniso ".
Dambudziko rakamuka nekuti chikamu chekuparara kwemahombekombe kunoitika pasi pemvura chinoita basa rakakosha mukuita kuti chiitiko ichi chiitike, saka sarudzo yekushandisa LiDAR sechishandiso chekugezesa.
Pawel akati, "Migumisiro yechidzidzo ichi inotipa ruzivo rwekuti mawere egungwa ari kupindura sei kushanduka kwemamiriro ekunze uye mune ramangwana, kunyanya kukwira kwegungwa uye kuwedzera kwemhepo." "Kuvandudza echinyakare geotechnical ongororo nekushandisa yakarongwa yepamberi yekunzwa matekinoroji, sekushandisa drones uye nendege ongororo, inopa muenzaniso kune dzimwe nzvimbo dzinotarisana nematambudziko akafanana. Maonero akawanikwa kubva muchidzidzo ichi anogona kuzivisa mahombekombe ekutonga mitemo kwete muPoland chete, asiwo mune mamwe matunhu ane akafanana geological uye ezvakatipoteredza mamiriro. kukukurwa kwemawere uye kusagadzikana."
Nekubatanidza ruzivo rwemuchadenga uye rwemugungwa ruzivo kubva kumotokari dzinozvimiririra, boka iri resainzi rakakwanisa kuvandudza kunaka kwedata, kunyatsoita mhedziso, uye kukwana kwezviito zvakatorwa kuderedza kukuvadzwa kweiyo geography nevagari venzvimbo dzakakanganisika.
