Lasy pokrywaj\u0105 prawie jedn\u0105 trzeci\u0105 powierzchni l\u0105dowej Ziemi. Wiele z nich jest tak rozleg\u0142ych, \u017ce jedynym sposobem na ich sporz\u0105dzenie mapy i zbadanie jest obserwacja z kosmosu.<\/p>\n<\/div>\n

Lasy s\u0105 nie tylko cennym \u017ar\u00f3d\u0142em drewna i paliwa, ale stanowi\u0105 r\u00f3wnie\u017c siedlisko dla wielu gatunk\u00f3w ro\u015blin i zwierz\u0105t.<\/p>\n

Drzewa zapobiegaj\u0105 r\u00f3wnie\u017c erozji gleby spowodowanej wiatrem i deszczem, wp\u0142ywaj\u0105 na lokalny klimat oraz spowalniaj\u0105 zmiany klimatyczne poprzez magazynowanie dwutlenku w\u0119gla.<\/p>\n

Niestety, lasy szybko si\u0119 kurcz\u0105. Ka\u017cdego roku ogromne obszary s\u0105 niszczone przez dzia\u0142alno\u015b\u0107 cz\u0142owieka.<\/p>\n

Przelatuj\u0105c nad ziemi\u0105, satelity mog\u0105 w ci\u0105gu zaledwie kilku dni uzyska\u0107 szczeg\u00f3\u0142owy obraz ca\u0142ego lasu. Stanowi\u0105 one jedyny szybki i \u0142atwy spos\u00f3b na sporz\u0105dzenie mapy nieustannie zmieniaj\u0105cych si\u0119 las\u00f3w oraz dostarczaj\u0105 regularnych aktualizacji dotycz\u0105cych ich stanu.<\/p>\n

Satelity ERS i Envisat nale\u017c\u0105ce do ESA s\u0105 wyposa\u017cone w radar obrazuj\u0105cy, kt\u00f3ry widzi przez chmury, umo\u017cliwiaj\u0105c wykrywanie zmian na powierzchni ziemi.<\/p>\n

Skaner dzia\u0142aj\u0105cy w zakresie \u015bwiat\u0142a widzialnego i podczerwieni s\u0142u\u017cy do badania wzrostu ro\u015blin oraz pomiaru temperatury powierzchni. Wykrywa on r\u00f3wnie\u017c po\u017cary wywo\u0142ywane w celu oczyszczenia p\u00f3l.<\/p>\n

Satelity potrafi\u0105 nawet rozr\u00f3\u017cnia\u0107 r\u00f3\u017cne gatunki drzew i pokazywa\u0107, w jakim s\u0105 stanie.<\/p>\n

Mapy oparte na zdj\u0119ciach satelitarnych pomagaj\u0105 zarz\u0105dcom i w\u0142adzom lokalnym chroni\u0107 i zachowa\u0107 kurcz\u0105ce si\u0119 lasy.<\/p>","protected":false},"excerpt":{"rendered":"
