Estimation of combustible material in Cerrado grassland area from RGB sensor im...
Souza, Igor Viana; Santos, Micael Moreira; Giongo, Marcos; Carvalho, Edmar Vinicius de; Silva Machado, Igor ElóiThe quantification of fuel material in the Cerrado area is limited by the difficulty in obtaining data, the high costs and the high time spent in the field. In search of alternatives that facilitate the data acquisition, the use of RGB sensors stands out being able to be a useful and effective tool in quantifying the combustible material. In this context, the objective of this work was to evaluate the feasibili...
Models of forest variables estimation using multispectral images
Machado, Igor Eloi Silva; Santos, Micael Moreira; Giongo, Marcos; Carvalho, Edmar Vinicius de; Ganassoli Neto, EduardoRemote sensing techniques for vegetation monitoring has been more used and improved. These techniques are good alternative to be used as as basis for forest inventories. The present study aims to estimate forest variables using multispectral images associated with data from field survey. The studied area was a tropical rain forest of approximately 44,728.5 ha. A forest inventory 100% was carried out providing t...
Evalution of forest fire occurrences in the State of Tocantins
Patriota, Jessica Nepomuceno; Batista, Antonio Carlos; Ganassoli, Eduardo; Santos, Micael Moreira; Coelho, Maria Cristina Bueno; Giongo, MarcosTocantins is one of the Brazilian states most affected by forest fires, which are the largest remnants of the country's Cerrado. Thus, this study aims to evaluate the Fire Occurrence Records (ROIs) in the state of Tocantins between 2003 and 2015 through the information provided by INPE and SisFogo. The work was divided into three stages: the first consists in the acquisition the images of the satellite AQUA and...
