Hazards and Population Mapper

NASA 

Mayelana nalolu hlelo lokusebenza

IHazards and Population Mapper (HazPop) uhlelo lokusebenza lwamahhala olunika abasebenzisi ithuba lokubonisa kalula idatha yengozi yemvelo ebudlelwaneni nabantu, ingqalasizinda enkulu, kanye nezithombe ze-satellite. Imininingwane yama hazard ifaka phakathi indawo yemililo esebenzayo emahoreni angama-48 edlule; izexwayiso zokuzamazama komhlaba ezinsukwini eziyisikhombisa ezedlule; kanye nedatha yokungcoliswa komoya izolo elinganiswe kusuka emkhathini. Uhlelo lokusebenza libonisa indawo yamadamu amakhulu nezitshalo zamandla enuzi futhi linikeza eminye imininingwane eningiliziwe nesithombe salezi zikhungo lapho zitholakala khona. Ngokudweba umbuthano ozungeze iphoyinti noma indawo yokuthakazelisa emephini, abasebenzisi bangathola isilinganiso sabantu bonke nendawo yomhlaba ebiyelwe ngaphakathi.

Kuthuthukiswe yiNASA Socioeconomic Data and Application Center (SEDAC) esebenza yiCentre for International Earth Science Information Network (CIESIN) eColumbia University, i-HazPop ihlanganisa idatha nezindawo zemephu ezivela emithonjeni ehlukahlukene kufaka phakathi i-NASA's Global Imagery Browse Services (GIBS), e-US. I-Geological Survey (i-USGS), nabanye abasebenzisa izinsiza zokubonisa imephu zeWebhu ezahlukahlukene. Ukuqagela kwesilinganiso sabantu kunikezwa abakwaSEDAC Population Estimation Service (PES) ngokususelwa kumininingwane ye-SEDAC's Gridded Population of the World, inguqulo 4 (GPWv4) yedatha ka-2015.

IHazPop yakhelwe ukuthi isetshenziswe ngabaphathi bezinhlekelele, izinhlangano eziphendula abantu, abezempilo yomphakathi, izintatheli nabanye abadinga ukuhlolwa okusheshayo ngobungozi obukhona obudalwa umcimbi omkhulu oyingozi noma ophuthumayo. Isibonelo, i-ejensi yokuphendula inhlekelele ingathola isilinganiso esibi sabantu kanye nezikhungo ezinkulu eziseduze nokuzamazama komhlaba kwakamuva njengendlela yokuhlela kokuphendula. Izintatheli noma abafundi bangabheka indawo okwenzeka kuyo imililo yasendle esanda kwenzeka lapho kuhlangana khona nezindawo ezinabantu abaningi, imigwaqo, izindawo zomhlaba, nezindikimba zamanzi. Ngenxa yokulungiswa kwamaza nekhwalithi ehlukile yeminye imininingwane, i-HazPop ayenzelwe ukuxhasa ukuhlolwa kobungozi ngokujulile noma izidingo zokuphendula endaweni ethile.
