Loss of Natural Habitats: High-Altitude Vegetation, Pantanal

The objective of this study is to quantify the spatiotemporal variation of high-altitude grassland (Campos de Altitude) in two different study areas between 1985 and 2020. First, the types of vegetation present in both areas were classified using a false-color (Red, Green, Blue) composition, with the channels replaced by mid-infrared, near-infrared, red, respectively. Following the definition of vegetation clas...

Study of the Impact of sanitary decisions over water quality using Bayesian Bel...

Bayesian Belief Networks (BBN) modeling the water quality has become popular due to advances in computational techniques. For this instance, BBN is a useful tool to modeling the relationship between water quality data and population or urbanization parameters on a watershed scale. This method can combine primary water quality data and decision parameters and help scientists and decision-makers analyze several s...

Evaluation of the depth of the Pantanal sedimentar basin based on seismic events

The main objective of this study is qualify the seismic activities captured at the Santo Antônio do Leverger seismic station (SALV), state of Mato Grosso, Brazil. The choice of this station was due to its location in the northern portion of the Pantanal Sedimentary Basin, considered historically as one of the seismogenic regions of Brazil. The methodology involved downloading the files through the poet.py scrip...

Estimating invasive grasses heights with images from a remotely piloted aircraf...

The purpose of this study was to estimate the height of invasive plants from UAV images using the GNSS integrated into the UAV and to evaluate the accuracy of the GNSS. DSM and DTM elevation models were produced from images collected by remotely piloted aircraft (RPA). The production of CHIS occurred through the subtraction of the DSM and the DTM. In order to assess the accuracy of the CHIS+GNSS model, the CHIS...

Image processing techniques for training photo interpreters in the visual asses...

Wetlands are one of the most valuable ecosystems on Earth, which are subjected to strong human pressure (burning) and natural processes such as fires. The Pantanal Sul-mato-grossense is an example. Large-scale monitoring of wetlands is of great importance, but also challenging. A collection of images from the Sentinel-2 satellite was used to characterize and monitor the Pantanal Sul-mato-grossense. The objectiv...

AERONAVE REMOTAMENTE PILOTADA DE BAIXO CUSTO NO ESTUDO DE PLANTAS INVASORAS EM ...

O objetivo dessa pesquisa é analisar se o método CHIS (Canopy Height Invasive Species) representa uma rotina de classificação assertiva na identificação de espécies invasoras a partir de imagens RGB em área de Cerrado com evidência de perturbação. A metodologia empregada foi a produção dos modelos de elevação MDS (Modelo Digital de Superfície) e MDT (Modelo Digital do Terreno) a partir das imagens coletadas em ...

Structural blocks as flood control in Brazilian Pantanal

Made available in DSpace on 2019-10-06T17:06:53Z (GMT). No. of bitstreams: 0 Previous issue date: 2018-01-01; The Pantanal basin formation and evolution are not well known and explained. This work brings new information showing the structural control over the physical environment of the Pantanal, one of the most important regions all around the world due to its biodiversity. We used different data sets from rem...
