Umhlaba njengobugcisa: imifanekiso yesathelayithi evela kwinkqubo yeLandsat

Intlango yaseCalifornia Mojave

ISebe le Idatha yaseMelika yeJografi idale ingqokelela emininzi ebizwa ngokuba "nguMhlaba njengobuGcisa" ukwenza imifanekiso yesathelayithi yeplanethi yoMhlaba. Ngale ndlela uqokelele i iifoto zobugcisa ezingakumbi ithathwe liqela leesathelayithi ezenza inkqubo yeLandsat.

Inkqubo yeLandsat yenziwe ngothotho lwemishini apho iisathelayithi zakhiwa kwaye zabekwa kwi-orbit yi-US. Ukuqwalaselwa okuphezulu komhlaba. I-satellite yokuqala ye-Landsat yasungulwa ngoJulayi 23, 1972. Eyokugqibela kuthotho yi-Landsat 8, eyaziswa nge-orbit ngo-Februwari 11, 2013.

Imifanekiso efunyenweyo imele iindawo emhlabeni Iziganeko zejoloji nezemozulu ngezinga eliphezulu lobugcisa. Le yindlela esinokuyigcina ngayo imifanekiso "ngombala wobuxoki". Oku kwenzeka ngenxa yokuba iisathelayithi ziqokelela imifanekiso ebonisa amaza abonakalayo nangabonakaliyo ombane wombane. Iliso lomntu alinakubona ngamehlo imibala ye-infrared Kodwa ngokongeza oku kukhanya kwimifanekiso eqhelekileyo, ivumela izazinzulu ukuba zijonge umhlaba ngemibala engeyiyo eyendalo.

Amafu e-Aleutian

Ukwakhiwa kwamafu kwintshona yeAluetian Islands. Umahluko ngombala mhlawumbi ubangelwa Umahluko kubushushu kunye nobungakanani bamathontsi enza amafu.

Umlambo iGanges Delta

Umlambo iGanges wenza i-delta ebanzi kakhulu efikelela kwi-Bay yase-Bengal.

IMalaspina Glacier

Ulwimi lweyona glacier inkulu eAlaska egubungela i-3880 square km. Emfanekisweni sibona kuchazwe kakuhle ukuhamba okulandelwe ngamanzi xa kubanda.

I-Phytoplankton eGotland

Lo mfanekiso ubonakalisa isitayile "seVan Gogh Starry Night" amabandla amakhulu e-phytoplankton eluhlaza kunxweme laseGotland, isiqithi saseSweden kunxweme loLwandle lweBaltic.

IParaná River Delta

Umphezulu womhlaba ubonakaliswe ngombala oluhlaza oqaqambileyo otshintsha phakathi kwe-magenta ephendula kweyona mimandla inabantu abaninzi, ngokuchaseneyo nobunzima bamanzi oMlambo iParaná

Iipateni zendalo

Ngaphandle kwamanzi, ngaphandle kotyani, ngaphandle kweoyase, isitya seTanezrouft eAlgeria yenye yezona ndawo zinamanzi eSahara.

Iipateni zendalo

Iimeko ezinzima zem mangrove ziboniswa ngombala oluhlaza omnyama kumacala oMlambo iOrd eOstreliya.

Iimpawu zeTessera

UMlambo iTietê uyayinyanzela le tessera mosaic eyenziwe ngemibala emininzi e-Ibitinga, eBrazil.

Iimpazamo

Xa iitectonic plates zingqubana, umaleko lwamatye luyaqhekeka. Izazi ngokuma komhlaba ziyibiza le nto "ngeempazamo." Kulo mfanekiso ungabona amanqanaba obunzulu obahlukeneyo bobunzima.

Iimpazamo

Amafu angummangaliso amathunzi

Lo mfanekiso ubunjwe ngeepateni ezenziwe ngamafu ngendlela emangazayo e-Egypt. Amafu abonakala ebomvu kwaye umhlaba uluhlaza okwesibhakabhaka phantsi kwempembelelo ye-infrared.

Ukubona igalari yonke yemifanekiso eqokelelwe yiyo yonke imisebenzi yeLandsat cofa apha Ungayikhuphela imifanekiso kwiJPG okanye kwi-TIF.
