Mosaïque du Groenland 2000 – Greenland Ice Mapping Project (GIMP)
Cet ensemble de données fournit une mosaïque d'images complète de la calotte glaciaire du Groenland, à une résolution de 15 m, dérivée des images ETM+ de Landsat 7 et des images SAR de RADARSAT-1 de 1999 à 2002. Ces méthodes combinent le masquage des nuages, l'accentuation du panoramique, l'échantillonnage et le redimensionnement des images, etc. arctique gimp groenland imagerie nasa polaire -

CCNL: ensemble de données sur les lumières nocturnes cohérent et corrigé à partir de DMSP-OLS (1992-2013) v1
Le jeu de données CCNL (Consistent and Corrected Nighttime Lights) est une version retravaillée de la version 4 du système OLS (Operational Line-Scan System) du programme de météorologie de défense (DMSP). Une série de méthodes a été utilisée pour atténuer l'impact de l'incohérence interannuelle, de la saturation et des effets de floraison, et pour améliorer les données … dmsp eog imagerie lumières nuit ols -
DMSP OLS: Global Radiance-Calibrated Nighttime Lights Version 4, Defense Meteorological Program Operational Linescan System
Le système OLS (Operational Line-Scan System) du programme de météorologie de défense (DMSP) a la capacité unique de détecter les sources d'émissions visibles et infrarouges proches (VNIR) la nuit. Cette collection contient des images globales de lumières nocturnes sans saturation des capteurs.

NAIP: National Agriculture Imagery Program
Le programme National Agriculture Imagery Program (NAIP) acquiert des images aériennes pendant les saisons de croissance agricole dans les États-Unis continentaux. Les projets NAIP sont sous-traités chaque année en fonction des fonds disponibles et du cycle d'acquisition d'images. Depuis 2003, NAIP est acquis sur un cycle de cinq ans. 2008 : agriculture haute résolution images orthophotos USDA
