See, kui j\u00f5ukalt me elame, paistab kosmossegi k\u00e4tte.<\/p>\n

Rahvusvaheline teadlasr\u00fchm, kus j\u00e4me ots oli Eestiga seotud teadlaste k\u00e4es, on n\u00e4idanud, kuidas satelliitide pealt kogutud vaatlusandmete j\u00e4rgi saab p\u00e4ris t\u00e4pselt j\u00e4rele vaadata, milline on elanike keskmine sissetulek suuremate linnade v\u00e4iksemates osades.<\/p>\n

Vaatluse all oli kolm maailma linna, Amsterdam Hollandis, New York Ameerika \u00dchendriikides ja Sydney Austraalias.<\/p>\n

Euroopa Kosmoseagentuuri seiresatelliitide Sentinel-1 ja Sentinel-2 pardalt tehtud piltidelt paistis, millised v\u00e4rvid ja ka silmale n\u00e4htamatu kiirguse lainepikkused eri linnaosades domineerisid.<\/p>\n

Tehisaru \u00f5ppis leidma seoseid nende satelliidiandmete ja riigiametitest saadud elanike keskmise sissetuleku ruumilise jaotuse andmete vahel m\u00f5nedes linnapiirkondades ning pakkus siis puhtalt satelliidiandmete p\u00f5hjal v\u00e4lja, milline v\u00f5iks olla elanike j\u00f5ukus teistes linnapiirkondades.<\/p>\n

<\/p>\n

Peale pelga v\u00e4rviinfo anal\u00fc\u00fcsis algoritm ka linnaosa visuaalset korrap\u00e4ra v\u00f5i korrap\u00e4ratust.<\/p>\n

Oleksandr Karasov Soomest Espoost Aalto \u00dclikoolist, kes on varem t\u00f6\u00f6tanud ka Tartu \u00dclikoolis, kirjutab koos Eesti, Soome ja Hollandi kolleegidega ajakirjas International Journal of Applied Earth Observation and Geoinformation<\/a>, et New Yorgi ja Sydney puhul \u00f5nnestus tehisarul m\u00e4\u00e4rata linnapiirkondade j\u00f5ukustase vastavalt 76 ja 78 protsendise t\u00e4psusega, Amsterdamis j\u00e4i t\u00e4psus 51 protsendi kanti.<\/p>\n

Anal\u00fc\u00fcs n\u00e4itas, et elanike j\u00f5ukus kippus k\u00f5rgem olema neis paigus, kus v\u00e4rviinfo j\u00e4rgi leidus suhteliselt rohkesti haljastust v\u00f5i veekogusid.<\/p>\n

Ka visuaalne korrap\u00e4ra andis m\u00e4rku suuremast j\u00f5ukusest, korrap\u00e4ratus aga pigem vaesemast elanikkonnast.<\/p>\n

Uuringu kaugem eesm\u00e4rk on pakkuda v\u00f5imalust saada \u00fclevaade elanike sissetulekutasemest eri linnaosades vahest isegi kiiremini k\u00e4tte kui ametlik statistika suudab pakkuda.<\/p>\n

Hellitatakse aga lootust saada sissetulekuandmeid ka niisuguste linnade kohta, n\u00e4iteks m\u00f5nel pool Aafrikas, kus statistika tegemine ongi kehval j\u00e4rjel.<\/p>\n

Pildil on Amsterdami kanali\u00e4\u00e4rne, kus on esindatud kosmossegi paistvad j\u00f5ukuse m\u00e4rgid \u2014 veekogu, rohelus ja korrap\u00e4ra.<\/p>\n
