An Alternative Method of Spatial Autocorrelation for Chlorophyll Detection in Water Bodies Using Remote Sensing

Additional measures of in situ water quality monitoring in natural environments can be obtained through remote sensing because certain elements in water modify its spectral behavior. One of the indicators of water quality is the presence of algae, and the aim of this study was to propose an alternative method for the quantification of chlorophyll [...]

Least trimmed squares estimator with redundancy constraint for outlier detection in GNSS networks

Global navigation satellite system (GNSS) networks facilitate accurate positioning over short and long distances on the surface of the Earth and expand the range of high-precision measurement. These networks are the basis not only for mapping activities, geoinformation, land registry and other location-based services, but also provide an important role in society as infrastructure works [...]

Determinação das Componentes do Desvio da Vertical para Estabelecimento de Referencial Batimetrico na Represa do Lobo, Itirapina – SP

O levantamento batimétrico consiste na coleta de profundidades georreferenciadas em leitos submersos. O Referencial altimétrico é necessário para redução das profundidades em altitudes ortométricas. As técnicas para transporte de coordenadas por métodos clássicos são morosas e caras. O GNSS (Global Navigation Satellite System) com correção em tempo real proporciona maior rapidez e confiabilidade na determinação [...]

An algorithm for automatic detection and orientation estimation of planar structures in LiDAR-scanned outcrops

The spatial orientation of linear and planar structures in geological fieldwork is still obtained using simple hand-held instruments such as a compass and clinometer. Despite their ease of use, the amount of data obtained in this way is normally smaller than would be considered as representative of the area available for sampling. LiDAR-based remote sensors [...]

Outcrop explorer: a point-based system for visualization and interpretation of lidar digital models

The use of LiDAR-based models for natural outcrops and surfaces studies has increased in the last few years. This technique has been found to be potential to represent digitally tridimensional data, thus it increases the quality and amount of data available for interpretation by geoscientists. Researchers, in computations, face difficulties in handling the huge amount [...]

An Automatic Algorithm for Minimizing Anomalies and Discrepancies in Point Clouds Acquired by Laser Scanning Technique

Laser scanning technique from airborne and land platforms has been largely used for collecting 3D data in large volumes in the field of geosciences. Furthermore, the laser pulse intensity has been widely exploited to analyze and classify rocks and biomass, and for carbon storage estimation. In general, a laser beam is emitted, collides with targets [...]

3-D Recosntruction Of Digital Outcrop Model Based on Multiple View Images and Terrestrial Laser Scanning

This paper presents a comparative study about 3D reconstruction based on active and passive sensors, mainly LiDAR – Terrestrial Laser Scanner (TLS) and raster images (photography), respectively. An accuracy analysis has been performed in the positioning of outcrop point clouds obtained by both techniques. To make the comparison feasible, datasets are composed by point clouds [...]

On evaluation of different methods for quality control of correlated observations

This paper evaluates, compares, and discusses different methods for quality control in geodetic data analysis in the general scenario of correlated observations and multiple outliers. The investigated methods are the data snooping procedure, the statistical tests for multiple outliers, the recently proposed quasi-accurate detection of outliers method for correlated observations, the Danish method for correlated [...]

Multi-Temporal Patterns of Urban Heat Island as Response to Economic Growth Management

For a reliable assessment of sustainability in big cities, it is imperative to evaluate urban ecosystem conditions and the environment of the cities undergoing economic growth. Urban green spaces are valuable sources of evapotranspiration, which is generated by trees and vegetation; these spaces mitigate urban heat islands in cities. Land surface temperature (LST) is closely [...]
