TL;DR: In this article, the state-of-the-art multispectral pansharpening techniques for hyperspectral data were compared with some of the state of the art methods for multi-spectral panchambering.

TL;DR: In this article, the authors describe a selection procedure of desert sites in North Africa and Saudi Arabia, of size 100 × 100 km2, using a criterion of spatial uniformity in a series of Meteosat-4 visible data.

TL;DR: In this article, state-of-the-art methods on shadow detection were surveyed and categorized into six classes: histogram thresholding, invariant color models, object segmentation, geometrical methods, physics-based methods, unsupervised and supervised machine learning methods.

TL;DR: The various methods implemented in the in-flight calibration plan and the results obtained during the instrument calibration phase are presented: absolute calibration over molecular scattering, interband calibration over sunglint and clouds, multiangular calibration over deserts and Clouds, intercalibration with Ocean Color and Temperature Scanner (OCTS), and water vapor channels calibration over singslint using meteorological analysis.

TL;DR: In this article, a scenario of large but realistic deployment of solar panels on the Paris metropolitan area is simulated, and it is shown that solar panels, by shading the roofs, slightly increases the need for domestic heating (3%).
