Comparison between two radiometric calibration methods applied to UAV multispectral images
(2020-01-01)
There are many advantages of using unmanned aerial vehicles (UAVs) in remote sensing but when using radiometrically corrected multispectral images. This study focuses on two techniques of obtain a multispectral orthomosaic ...
Spectral and Atmospheric Characterization of a Site at Atacama Desert for Earth Observation Sensor Calibration
(Institute of Electrical and Electronics Engineers, 2015)
The application of Earth observation sensor data in quantitative approaches calls on the conversion of original digital numbers to radiometric quantities such as radiance or reflectance. This conversion depends on the ...

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. ...
Workflow to spectral imagery calibration obtained in remotely piloted aircrafts (RPAs) by the empirical line methodFluxo de trabalho para a calibração de imagens espectrais obtidas em aeronaves remotamente pilotadas (ARPs) pelo método da linha empírica
(2019-01-01)
The usage of Remotely Piloted Aircrafts (RPAs) in environmental studies increased over the past years due to the possibility of performing low-cost aerial image acquisition. However, these studies often need to extract ...
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 ...
Radiometric Cross-Calibration of the Chilean Satellite FASat-C Using RapidEye and EO-1 Hyperion Data and a Simultaneous Nadir Overpass Approach
(MDPI AG, 2016)
The absolute radiometric calibration of a satellite sensor is the critical factor that ensures the usefulness of the acquired data for quantitative applications on remote sensing. This work presents the results of the first ...
