Initial analysis from a Lidar observation campaign of sugar cane fires in the central and western portion of the S̃ao Paulo State - Brazil
The central and western portion of the S̃ao Paulo State has large areas of sugar cane plantations, and due to the growing demand for biofuels, the production is increasing every year. During the harvest period some plantation ...
Lidar observation campaign of sugar cane fires and industrial emissions in the State of São Paulo, Brazil
Brazil has an important role in the biomass burning, with the detection of approximately 100,000 burning spots in a single year (2007). Most of these spots occur in the southern part of the Amazon basin during the dry ...
The laser-backscattering equations and their application to the study of the atmospheric structure
(Revista Mexicana de Física, 2009)
Development of a high-spectral-resolution lidar for continuous observation of aerosols in South America
(Society of Photo-Optical Instrumentation Engineers, 2016-05)
Continuous monitoring of aerosol profiles using lidar is helpful for a quasi-real-time indication of aerosol concentration. For instance, volcanic ash concentration and its height distribution are essential information for ...
Uso integrado de dados LiDAR e imagens aéreas aplicado na extração de contornos de telhados de edificações
(Universidade Estadual Paulista (UNESP), 2016-02-29)
Esta dissertação contempla o desenvolvimento de um método que combina os dados LiDAR (Light Detection And Ranging) obtidos por sistema de varredura LASER (Light Amplification by Stimulated Emission of Radiation) e imagens ...
BUILDING ROOF BOUNDARY EXTRACTION FROM LiDAR AND IMAGE DATA BASED ON MARKOV RANDOM FIELD
(Copernicus Gesellschaft Mbh, 2017-01-01)
In this paper a method for automatic extraction of building roof boundaries is proposed, which combines LiDAR data and high-resolution aerial images. The proposed method is based on three steps. In the first step aboveground ...
Measurement method of high spectral resolution lidar with a multimode laser and a scanning Mach-Zehnder interferometer
(OSA - The Optical Society, 2017-07)
A simple high spectral resolution lidar technique using a multi-longitudinal mode laser is proposed for measuring aerosol extinction and backscattering coefficients. A scanning interferometer having the same free spectral ...
