SYNERGY BETWEEN LiDAR AND IMAGE DATA IN CONTEXT OF BUILDING EXTRACTION
(Copernicus Gesellschaft Mbh, 2014-01-01)
This paper compares the paradigms of LiDAR and aerophotogrammetry in the context of building extraction and briefly discusses a photogrammetric strategy for refining building roof polyhedrons previously extracted from LiDAR ...
Method to detect molecular ranges in elastic lidar signalMétodo para detectar rangos moleculares en señales lidar elásticas
(Sociedad Española de Óptica, 2017-09)
A method to detect aerosol plumes or clouds from an elastic lidar signal is presented, as well the determination of the atmospheric boundary layer height. It is based on the Rayleigh-fit concept, where the range-corrected ...
Initial analysis from a Lidar observation campaign of sugar cane fires in the central and western portion of the S̃ao Paulo State - Brazil
(2011-11-17)
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 ...

Three-dimensional building roof boundary extraction using highresolution aerial image and LiDAR data
(2014-01-01)
This paper presents a semiautomatic method for rectilinear building roof boundary extraction, based on the integration of high-resolution aerial image and LiDAR (Light Detection and Ranging) data. The proposed method is ...
Classification of LiDAR data over building roofs using k-means and principal component analysisClassificação de dados LiDAR sobre telhados de edificações usando k-médias e análise de componentes principais
(2018-01-01)
The classification is an important step in the extraction of geometric primitives from LiDAR data. Normally, it is applied for the identification of points sampled on geometric primitives of interest. In the literature ...
Building detection from lidar data using entropy and the k-means concept
(2019-06-04)
Information obtained from LiDAR data processing is considered in a variety of applications, among them urban planning. In this context, buildings play a substantial role, since a high percentage of the urban landscape is ...
Estudo de propriedades físicas de nuvens Cirrus em Natal utilizando dados do sistema Lidar-DUSTER e radiossondagens
(Universidade Federal do Rio Grande do NorteBrasilUFRNEngenharia Ambiental, 2018-07-06)
Cirrus clouds are classified as the highest clouds in the atmosphere occurring generally from 7 to 18 km, depending on the global region of appearance, and have necessarily ice crystals in their composition. They still ...
The use of Otsu algorithm and multi-temporal airborne LiDAR data to detect building changes in urban space
(Springer, 2021-04-24)
Building change detection techniques are essential for several urban applications. In this context, multi-temporal airborne LiDAR data has been considered an effective alternative since it has some advantages over conventional ...
