NOAA CoastWatch distributes chlorophyll-a concentration data from NASA's Aqua satellite. Measurements are gathered by the Moderate Resolution Imaging Spectroradiometer (MODIS) carried aboard the spacecraft. Data is received from the satellite and processed to level 2 by the Oregon State University (OSU) College of Oceanic and Atmospheric Sciences (COAS).

La donnée a été créée ou dérivée à partir d'images de véhicules aériens non habités (UAV) acquises à partir d'une enquête d'une journée, le 28 juillet 2016, à Cambridge Bay, au Nunavut. Cinq points de contrôle provenant d'un système de positionnement différentiel global ont été positionnés dans les coins et au centre de l'étude de la végétation. Les jeux de données suivants couvrent une superficie de 525m2 et ont été produits par le Centre canadien de télédétection / Centre canadien de cartographie et d'observation de la Terre: - UAV modèle d'hauteur de la végétation, Cambridge Bay, Nunavut - UAV modèle numérique de surface (MNS) dans Cambridge Bay, Nunavut - Parcelle de végétation - UAV orthomosaïque de Cambridge Bay, Nunavut - Parcelle de végétation L'enquête sur les UAV a été menée en collaboration avec La Station canadienne de recherche dans l’Extrême-Arctique (SCREA) pour la recherche sur la surveillance de la végétation nordique.

AVHRR Pathfinder Oceans Project seeks to create a long-term, continuous sea surface temperature data series for use in climate research. The Pathfinder SST data begins with historic AVHRR Global Area Coverage SST. This data is re-evaluated and re-calibrated, improving both the accuracy and number of valid SST values (due to improved cloud-masking).

Aviso Absolute Sea Surface Height is the Sea Surface Height Deviation plus the long term mean dynamic height. This is Science Quality data.

The 2008-12 Saskatchewan Orthophotography Project provides seamless, accurate province wide ortho-rectified nadir aerial photography and elevation data of the earth's surface for use in geographic information systems (GIS). The imagery , when complete in 2012, will cover the entirety of the Saskatchewan landmass, with a 100 metre buffer beyond the provincial border, an area of approximately 654,000 sq.km. An ongoing OrthoPhoto refresh program is planned to commence in 2012. The color orthophotos have a 62.5 centimter pixel resolution. Digital Orthophotography Products are as follows: 1) Black and White ortho-photography by township tile [tif and tfw]; 2) Color Ortho-photography by township tile [tif and tfw]; 3) Color Infrared Images by photo frame; ortho-rectified but unmosaiced [tif and tfw]; 4) Digital Elevation model by township tile - 100m grid and breaklines [shp and usgs.dem]; 5) Overlapping aerial photography by camera photo frame for stereo viewing [tif and tfw]; 6) Exterior orientation data and camera calibration data (Pat-B EO and Z1 formats]. The complete OrthoPhoto Data Series consists of over 7000 individual township tiles and more than 20TB of spatial information.
