Relative Radiometric Calibration Using Tie Points and Optimal Path Selection for UAV Images

Remote Sensing, 2020
As the use of unmanned aerial vehicle (UAV) images rapidly increases so does the need for precise radiometric calibration. For UAV images, relative radiometric calibration is required in addition to the traditional vicarious radiometric calibration due ...

Development of an Operational Calibration Methodology for the Landsat Thermal Data Archive and Initial Testing of the Atmospheric Compensation Component of a Land Surface Temperature (LST) Product from the Archive

Remote Sensing, 2014
The Landsat program has been producing an archive of thermal imagery that spans the globe and covers 30 years of the thermal history of the planet at human scales (60–120 m). Most of that archive’s absolute radiometric calibration has been fixed through

Vicarious calibration of the Geostationary Ocean Color Imager

Optics Express, 2015
Measurements of ocean color from Geostationary Ocean Color Imager (GOCI) with a moderate spatial resolution and a high temporal frequency demonstrate high value for a number of oceanographic applications. This study aims to propose and evaluate the calibration of GOCI as needed to achieve the level of radiometric accuracy desired for ocean color ...

The impact of family interview on the relationship between medical students and their silent mentor

Anatomical Sciences Education, EarlyView.
Abstract The gross anatomy laboratory course often triggers significant negative emotions in medical students during dissection. While various pedagogical interventions aim to alleviate psychological burden, the fundamental question of how students' perceptions of donors evolve throughout the course remains underexplored.

Measuring the Burden of Choice: Development and Validation of a Choice Overload Scale

Journal of Consumer Behaviour, EarlyView.
ABSTRACT Excessive choice imposes substantial cognitive demands on consumers, impair decision‐making, and generate negative consumer responses—a phenomenon widely known as the choice overload effect. Despite its conceptual prominence in consumer research and its enduring relevance in today's consumer markets, existing approaches to measuring choice ...

Consideration of Correlations in Radiometric Measurements of the Environment

Remote Sensing
Vicarious calibration is a technique that makes use of radiometrically stable targets such as dry lakebeds, desert sites, and open grasslands for the post-launch calibration of a satellite sensor.
