These are study areas from a PELD project.<br \/>\nThe Pampa biome, in the Southern region of Brazil, is covered mainly with grasslands and is considered of extreme importance, due to its great biological diversity. The conservation status and extension of vegetation cover is still not well known for the Pampa, although important when monitoring the behavior of vegetation when there are significant changes in climate.<br \/>\nVegetation monitoring has been supported with the development of spectral profiles based on data from different orbital sensors. With the MODIS sensor it is possible to obtain data of Vegetation indices, such as the Normalized Difference Vegetation Index (NDVI) and the Enhanced Vegetation Index (EVI), used to monitor changes in vegetation and phenology over time.<br \/>\nCombined with analytical methods, the dynamics of vegetation can be studied. The wavelet analysis was used, as the wavelet function captures the local and global behavior of a temporal series and shows where and when changes occur. The power spectra for the EVI presented greater variability that the NDVI in different periods of the series.<\/p>\n<p><strong><a href=\"http:\/\/www.dsr.inpe.br\/sbsr2013\/files\/p0449.pdf\">Saiba mais<\/a><\/strong><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Autores: Ana Carolina Rodrigues Silveira, Tatiana Mora Kuplich, Andreise Moreira, Daniela Wancura Barbieri, Gerhard Ernst &hellip;<\/p>\n","protected":false},"author":1,"featured_media":849,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[117],"tags":[],"class_list":["post-978","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-artigos-cientificos"],"_links":{"self":[{"href":"https:\/\/www.ufrgs.br\/redecampossulinos\/wp-json\/wp\/v2\/posts\/978","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.ufrgs.br\/redecampossulinos\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.ufrgs.br\/redecampossulinos\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.ufrgs.br\/redecampossulinos\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.ufrgs.br\/redecampossulinos\/wp-json\/wp\/v2\/comments?post=978"}],"version-history":[{"count":2,"href":"https:\/\/www.ufrgs.br\/redecampossulinos\/wp-json\/wp\/v2\/posts\/978\/revisions"}],"predecessor-version":[{"id":1003,"href":"https:\/\/www.ufrgs.br\/redecampossulinos\/wp-json\/wp\/v2\/posts\/978\/revisions\/1003"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.ufrgs.br\/redecampossulinos\/wp-json\/wp\/v2\/media\/849"}],"wp:attachment":[{"href":"https:\/\/www.ufrgs.br\/redecampossulinos\/wp-json\/wp\/v2\/media?parent=978"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.ufrgs.br\/redecampossulinos\/wp-json\/wp\/v2\/categories?post=978"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.ufrgs.br\/redecampossulinos\/wp-json\/wp\/v2\/tags?post=978"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
