Performance evaluation of sequential band orientation by polynomial models in hyperspectral cubes collected with uav
(2019-06-04)
A study on orientation of hyperspectral band cubes acquired with frame camera is presented in this paper. The camera technology is based on a tuneable Fabry-Perot Interferometer (FPI) and captures cubes of images sequentially ...
Tie point generation in hyperspectral cubes for orientation with polynomial models
(2019-01-01)
This paper presents a technique for tie point generation in hyperspectral images collected by a camera with time-sequential principle for band acquisition (i.e., non-synchronized bands). In mobile applications, each band ...
Methodology for Land Mapping of Amapa State-A Special Case of Amazon Radiography Project
(2020-09-26)
The Brazilian Amazon has been mapped by the Brazilian Army Geographic Service (DSG) on the Amazon Radiography project using synthetic aperture radar (SAR) technology. The Amapa State is a special case of this project because ...
Estimating exterior orientation parameters of hyperspectral bands based on polynomial models
(2017-10-19)
Hyperspectral camera operating in sequential acquisition mode produces spectral bands that are not recorded at the same instant, thus having different exterior orientation parameters (EOPs) for each band. The study presents ...
GEOMORPHIC INDEXES APPLIED TO TECTONIC DEFORMATION STUDY: A REVIEW
(Uniao Geomorfologia Brasileira, 2019-04-01)
This work gathers and discusses the major techniques of geomorphic indexes developed by several researchers over time, and currently applied to tectonics/neotectonics/active tectonic deformation study. Drainage is the most ...
Use of remote sensing and gis mapping in geoenvironmental mapping of subzones of Cujubim (RO)municipality as aid assessment of agricultural ability.
(Revues Org, 2016-01-01)
This text has as its main objective to perform the mapping of zones and subzones, considering the physical aspects of land of the Cujubim Municipality, situated in the state of Rondonia / Brazil, with the aim of contributing ...
METHODOLOGY FOR THE EXTRACTION OF HOMOLOGOUS POINTS FROM A DEM/DSM TO EVALUATE THE RELATIVE POSITIONAL ACCURACY
(Univ Federal Parana, Centro Politecnico, 2020-01-01)
This work presents a new methodology for extracting 3D homologous points from a DEM/DSM for relative evaluation of positional accuracies, from terrain features such as ridgelines and hydrography. Firstly, it extracts 3D ...
Basement structures over Rio Grande Rise from gravity inversion
(2017-04-01)
The basement depth in the Rio Grande Rise (RGR), South Atlantic, is estimated from combining gravity data obtained from satellite altimetry, marine surveys, bathymetry, sediment thickness and crustal thickness information. ...
Efecto de propiedades edáficas sobre la productividad de los cultivos de maíz y soja en La Pampa arenosa
(Universidad Nacional de La Pampa, 2016-09)
La productividad alcanzada por los cultivos es el resultado del genotipo, el ambiente, y la interacción de ambos factores. En la pampa arenosa bajo igual condición climática e iguales prácticas de manejos se observa ...
The 2016 red tide crisis in southern Chile: Possible influence of the mass oceanic dumping of dead salmons
(Elsevier, 2020)
In 2016, a massive harmful algal bloom (HAB) of Alexandrium catenella around Chiloe island caused one of the major socio-ecological crisis in Chilean history. This red tide occurred in two distinct pulses, the second, most ...
