Comparison of NDVI for different species of eucalyptus
Goergen, Laura Camila de Godoy; Silva, Matheus Nunes; Silva, Emanuel Araújo; Pereira, Rudiney SoaresThe study aimed to analyzed the vegetation from NDVI (Normalized Difference Vegetation Index) dynamics in Eucalyptus dunnii and Eucalyptus Urograndis comparing the NDVI generated from the digital numbers obtained from the conversion to apparent reflectance. The satelite images of TM/Landsat 5 sensor was used. Converting digital numbers (DN) to reflectance values and the calculation of the NDVI were obtained thr...
ANÁLISE DA RELAÇÃO ENTRE A EVOLUÇÃO FLORESTAL E A DECLIVIDADE UTILIZANDO IMAGEN...
Marchesan, Juliana; Pedrali, Letícia Daiane; Tramontina, Juliana; Alba, Elisiane; Mello, Eliziane Pivoto; Pereira, Rudiney SoaresO presente estudo teve por objetivo analisar a evolução da cobertura florestal e sua relação com a declividade, no município de Agudo, RS, entre os anos de 2010 e 2014. Foram utilizadas imagens do satélite Landsat 5, para o ano de 2010, e Landsat 8, para o ano de 2014, para o mapeamento do uso e cobertura da terra, por meio da classificação MaxVer, criando-se quatro classes: “Floresta”, “Agricultura/Pecuária”, ...
Spectral indices for chlorophyll seasonal dynamics analysis in leaves of Eucaly...
Goergen, Laura Camila de Godoy; Soares, Julio Cesar Wincher; Berra, Elias Fernando; Brandelero, Catize; Pereira, Rudiney SoaresThe objective of this study was to evaluate the performance of different spectral indices - MCARI705, R750/R700, R750/R550 and MTCI - in the description of chlorophyll seasonal dynamics in detached leaves of Eucalyptus grandis in four seasons. The study was conducted in three plots of 600 m2, in a 20 months old stand. We collected 15 leaves from three layers of canopy, totalizing 45 leaves for each season. It w...
Dynamics of use and land cover in the Rio Pardo valley, Rio Grande do Sul
Schroder, Thomas; Pereira, Rudiney Soares; Zimmermann, Anna Paula Lora; Redin, Cristina Gouvêa; Fleck, Marciane Danniela; Machado, Leonardo MortariThe aims of this study were to evaluate rates of deforestation and forest regeneration in the time span between 1990 and 2014, furthermore to estimate land cover and use by the year of 2018 in the Rio Pardo Valley region. Landsat images were used for land cover and use classification and Dinamica EGO software was used to provide real and estimated transitions among land cover and use classes. Forested area incr...

COMPARISON BETWEEN MANUAL AND AUTOMATIC DELIMITATION OF CORUPÁ STREAM WATERSHED...
Goergen, Laura Camila de Godoy; Schuh, Mateus Sabadi; Pereira, Rudiney Soareshttp://dx.doi.org/10.5902/223611707277Several environmental impacts such as deforestation, soil erosion, water pollution and chaoticurban occupation are related to lack of planning in land use in watersheds. For proper planningand management of water resources is critical to proper delineation of watersheds. Thus, thisstudy aimed to analyze a methodology for automatic delineation of watersheds in the basin of t...
Temporal and spatial dynamics of the soil usage in the micro-region of Campanha...
Brites, Daiana Iris Soto; Silva, Emanuel Araújo; Goergen, Laura Camila de Godoy; Nunes, Matheus Mesquita da Costa; Pereira, Rudiney Soareshttp://dx.doi.org/10.5902/223611708706This article aims to present the temporal evolution occurred on soil use in 1992 and 2010 in the microregion Central Campaign of Rio Grande do Sul, giving prominence to forests´ transition. The images from the Landsat TM sensor platform 5 and the Spring application, was classified images, determining the following land use classes: bare soil, water, agricultural use, sand, ...
