TL;DR: Results were promising, indicating that hyperspectral 3D remote sensing was operational from a UAV platform even in very difficult conditions, and are expected to provide a powerful tool for automating various environmental close-range remote sensing tasks in the very near future.

TL;DR: Evaluated performance of images of the sensor Operational Land Imager onboard the Landsat-8 satellite in determining Chl-a concentrations and estimating the trophic level in a tropical reservoir showed reasonable results, but their performance was likely impaired by the atmospheric correction.

TL;DR: The convolutional neural network approach developed to estimate the number and geolocation of citrus trees in high-density orchards is satisfactory and is an effective strategy to replace the traditional visual inspection method to determine the number of plants in orchard trees.

TL;DR: A robust and efficient technique to segment shaded areas in aerial color images is presented here, based on the physical phenomenon of atmospheric dispersion of the sunlight most well known as the Rayleigh scattering effect.

TL;DR: The results indicate that, for the Valencia-orange leaves, surface reflectance data is more suitable to predict macronutrient content, while first-derivative spectra is better linked to micronutrients.
