Ibhuku lokuHlola elikude lamahhala

I-PDF version yedokhumenti itholakala ukulanda Ukubonwa kweSatellites ekude ukuPhathwa kweziNdawo. Umnikelo obalulekile futhi njengamanje uma sicabanga ngokubaluleka lokhu okuye kwaba nakho ekuthatheni izinqumo zokuphathwa kahle kwamahlathi, ezolimo, izinsiza zemvelo, isimo sezulu, ukuhlelwa kwamabalazwe kanye nokuhlelwa kokusetshenziswa komhlaba.

Ngokusho kwedatha ekhishwe ku-Union of Concerned Scientists http://www.ucsusa.org kuya kuFebhuwari ye-2012 kwakukhona ngaphezu kwama-satellite e-900 ajikeleza umhlaba, lapho iningi, cishe i-60%, lingukuxhumana. Ama-satellite aqondayo ekude aphakathi kwe-120.

Lo mbhalo uhlanganisa nomlando ongacabangi, ngoba inqubekela phambili esheshayo emashumini eminyaka amuva nje ingasenza sikhohlwe ukuthi ukuqala kwalesi sifundo bekungakudala, kepha bekuyinto ethuthuke kakhulu kubuchwepheshe besikhala. Namuhla amandla okuzwa okukude ekunikezweni okubanzi kwezithombe ezithwetshulwe yiziphuphutheki eziningi ezizungeza iplanethi, kepha lokhu kwehluka okufanayo kubangela ukudideka okulinganayo ukuqonda ukubaluleka kwedatha.

Yilokho kanye lapho incwadi igxila khona. Kufaka isingeniso sokuzwa okukude ukugcwalisa izidingo zoqeqesho lwethiyori kanye nohlu lwamagama. Kodwa amandla edokhumende akuleso sethulo ngesimo sekhathalogi ehlelekile nesebenzayo yamasathelayithi asezingeni eliphezulu asetshenziswa kakhulu futhi aphakathi nendawo, kanye nemingcele eyisisekelo yokuthola izithombe zesathelayithi. Umzamo omkhulu wokuhlanganisa okuqukethwe ngoba imininingwane imvamisa ibanzi kakhulu futhi ihlakazekile. Akungabazeki ukuthi kuzosiza labo abanentshisekelo ukwazi ukusebenza kokuzwa okukude esiyalweni sabo, ngoba ubuthakathaka obukhulu kube ngukungabi nokusatshalaliswa okuhlelekile; lokho okufezwa yilo mbhalo ngokuqinisekile.

Indlela yokukhetha ama-satellite echazwe encwadini yayiyi:

• Ukuthi basebenza ngosuku lokulungiselela le ncwadi. (Februwari ka-2012)
• Ukuthi banesisombululo sendawo esilingana noma esingaphezu kwamamitha angu-30 / pixel cishe.
• Ukuthi imikhiqizo yabo yayitholakala ngezinye izindlela ezilula zokuthengisa.

Izinzwa ze-RADAR zohlobo lwama-microwave zishiywe ngaphandle kuleli khathalogi. Yize lezi zinethuba lokukwazi ukusebenza cishe kunoma yisiphi isimo sezulu (amafu, imvula encane, njll.), Ukucubungula nokuchazwa kwezithombe zazo kudinga indlela ehluke kakhulu kunaleyo ebikiwe kulo mbhalo.

Futhi ngamunye wabo ulwazi lufingqiwe efomini lesithombe esiwusizo kakhulu njengoba kuchazwe ngezansi:

• Insimu yokuqala ibonisa igama lensiza, okubhekene ne-satellite eminingi, elilodwa kuphela, likhethiwe ukukhombisa igama le-satellite ngokwayo. Endabeni yama-satellite enezinzwa eziningana, amabhokisi amaningana angeziwe, eyodwa yesinzwa ngayinye.
• Insimu yesibili ibonisa isinqumo sendawo esinikezwe inzwa. Lokhu kungahlukahluka ngokuya ngombono wokubuka kwe-satellite, ukuze okungenani kunokwenzeka kuboniswe obala we-orbit (nadir). Endabeni yama-satellite anezinzwa eziningana, isinqumo sendawo ngasinye sichaziwe.
• Insimu yesithathu ibonisa inani lama-spectral bands anikezwe inzwa.
• Iwesine Kubonisa ukulungiswa kwesikhashana senzwa. Le datha ibonakala ingenangqondo, ngoba lesi sici sihlukahluka kuye ngokuthi i-latitude ne-angle yimuphi i-satellite "ephoqelelwa" ukuthola isithombe. Ngakho-ke idatha ebonakalayo ikhombisa futhi inezinhloso zayo ukuthi umfundi uthola umbono we-periodicity okungenzeka ukuthi i-satellite itholakala endaweni efanayo.
• Futhi owokugcina ubonisa intengo encane engamakhilomitha ayikhilomitha wesithombe esithunyelwe ngosuku lokulungiselela le khathalogi. Kukhethiwe ukufaka lolu lwazi ukuze umfundi abe nomqondo oseduze wokuthi kuzodingeka yini ukuthola isithombe sendawo ethize. Inani lokugcina lixhomeke ezintweni eziningi (ukulinganisa usayizi, kuqala, amaphesenti amancane wefu, izinga lokucubungula isithombe, izaphulelo ezingenzeka, njll) ngakho kuzodingeka njalo uxhumane nenkampani yomphakeli futhi unqume ncamashi uhlobo umkhiqizo odingekayo ukuze ukwazi inani eliqondile.

Nakanjani kufanele ulande idokhumenti, uyifunde, uyilondoloze ekuqoqweni kokufundwayo okuthandayo bese wabelana ngakho. Ngifingqa uhlu lokuqukethwe.

Kubukeka ngathi umsebenzi obalulekile, oza kithi kusuka kuphrojekthi "Ukusetshenziswa kwezithombe zesathelayithi ezinesinqumo esiphezulu sokuphatha indawo yaseMacaronesia" (I-SATELMAC), evunyelwe ocingweni lokuqala lweTransnational Cooperation Programme - Madeira Azores Canarias (PCT-MAC) 2007-2013. I-General Directorate of Agriculture and Rural Development yoMnyango Wezolimo, Imfuyo, Ezokudoba kanye Namanzi kaHulumeni waseCanary Islands isebenza njengeNhloko Yemigqa, kanti iNyuvesi i-Earth and Atmosphere Observation Group ingabalingani ababambe iqhaza. weLa Laguna (GOTA) kanye ne-Regional Institute of Agrarian Management, ye-Azores (IROA).

Siyavuma isikweletu salomzamo, ne-Cartesia yokwabelana ngesixhumanisi nge-LinkedIN.
