Impact of reduction of radiometric resolution in hyperspectral images acquired over forest field
(2018-09-20)
The objective of this study was to evaluate the impact of reducing the radiometric information of hyperspectral images. The image data was collected originally with 32 bits and rescaled to 8 and 16 bit/pixel. The images ...
Analysis of the radiometric response of orange tree crown in hyperspectral uav images
(2017-10-19)
High spatial resolution remote sensing images acquired by drones are highly relevant data source in many applications. However, strong variations of radiometric values are difficult to correct in hyperspectral images. ...
Radiometric block adjustment of hyperspectral image blocks in the Brazilian environment
(2018-08-18)
The objective of this investigation was to study and optimize a hyperspectral unmanned aerial vehicle (UAV)-based remote-sensing system for the Brazilian environment. Comprised mainly of forest and sugarcane, the study ...
A first in-flight absolute calibration of the Chilean Earth Observation Satellite
(Elsevier, 2014)
This work describes the first in-flight absolute calibration of the ‘‘Sistema Satelital para la Observación de la
Tierra’’ (SSOT or Fasat-C). It was performed on January 29th 2013 at Antumapu site located in the southern
area ...
Super resolution images from mosaics
(Universidade Federal Fluminense (UFF)Rio de Janeiro, 2013)
In order to extract information from images, the
resolution and its application must be observed. This resolution
depends basically on the physical characteristics of the sensor
responsible for capturing these images, ...
Mapping daily evapotranspiration at field to continental scales using geostationary and polar orbiting satellite imagery
(COPERNICUS GESELLSCHAFT MBH, 2011)
Thermal infrared (TIR) remote sensing of land-surface temperature (LST) provides valuable information about the sub-surface moisture status required for estimating evapotranspiration (ET) and detecting the onset and severity ...
Above-ground biomass estimation for Quercus rotundifolia using vegetation indices derived from high spatial resolution satellite images
(2018-01-01)
The estimation of vegetation parameters, such as above-ground biomass, with high accuracy using remote sensing data, represents a promising approach. The present study develops models to estimate and map above-ground biomass ...
