Landsat Level2A images (Theia) | Reflectance Landsat images (Level 2A) processed by the Theia Land Data Center (http://www.theia-land.fr) for the CNES French Space Agency (http://www.cnes.fr). The processing center developed by CNES uses the MACCS prototype L2A chain developed and designed by CESBIO. LANDSAT 8 L1T Input data come from USGS (http://earthexplorer.usgs.gov) that we would like to thank for releasing freely the LANDSAT 8 datasets. |
Landsat-8 Collection (EO IPT.PL) | Landsat-8 products stored in the catalog provided by the Earth Observation Innovative Platform Testbed Poland. Landsat 8 level 1 products combine data from the 2 Landsat instruments; OLI and TIRS. The level 1 products generated can be either L1T or L1gT. Level 1T data products consist of radiometrically corrected image data derived from L0 data scaled to at-aperture spectral radiance or reflectance that are resampled for registration to a cartographic projection (referenced to the WGS84, G873 or current version). The L1T product is orthorectified, and corrected for terrain relief. The geometric corrections use observatory ephemeris data and ground control points; DEM data is used to correct for terrain relief. Geometrically corrected products L1gT data products consist of L0 product data with systematic radiometric, geometric and terrain corrections applied and resampled for registration to a cartographic projection, referenced to the WGS84, G873, or current version. L1gT data products assume the use of on-board positional information or definitive ephemeris, as well as the use of controlled elevation data to correct for parallax errors. In case of insufficient GCP, caused by extensive snow/cloud cover, which makes the orthorectification impossible, products of this level are produced instead of L1T. |
SpotWorldHeritage (Theia) | Multispectral decametric images from the Spot 1-5 archive of more than 5 years old, acquired in the framework of the Spot World Heritage programme, based on a partnership between CNES and Airbus Defence and Space. The images are available on a free and open basis for any user, provided usage is non-commercial |
SPOT5 stereoscopic survey of Polar Ice (Theia) | Astrium Services and CNES supplied satellite data for the international Polar Year research programmes. Earth-observing satellites are mapping the poles to provide scientists with a more precise picture of how glaciers are changing and to help them understand the impacts of climate change on our planet. Astrium Services and CNES joined the SPIRIT project (SPOT 5 stereoscopic survey of Polar Ice: Reference Images and Topographies) in partnership with French survey, the French mapping agency IGN and the LEGOS, space geophysics and oceanography research laboratory. During two years, from 2007 to 2009, an archive of SPOT 5 HRS images was compiled over polar ice in order to produce DTMs and ortho-image |
Sentinel-2 (PEPS) | The SENTINEL-2 mission is a land monitoring constellation of two satellites each equipped with a MSI (Multispectral Imager) instrument covering 13 spectral bands providing high resolution optical imagery (i.e., 10m, 20m, 60 m) every 10 days with one satellite and 5 days with two satellites. |
Sentinel-1 Products | Sentinel-1 is a polar-orbiting, all-weather, day-and-night radar imaging mission for land and ocean services. The first Sentinel-1 satellite was launched on a Soyuz rocket from Europe's Spaceport in French Guiana on 3 April 2014. This collection groups both the SAR Level-0 products and SAR Level-1 that includes the Single Look Complex (SLC), Ground Range Detected (GRD) products. Level-2 Ocean (OCN) products for retrieved geophysical parameters of the ocean are also part of this collection. |
Sentinel-3 Products | The main objective of the SENTINEL-3 mission is to measure sea surface topography, sea and land surface temperature, and ocean and land surface colour with high accuracy and reliability to support ocean forecasting systems, environmental monitoring and climate monitoring. This collection represents the Level-1 and Level-2 Full OLCI products. These products include Top-Of-Atmosphere (TOA) radiometric measurements, radiometrically corrected, calibrated and spectrally characterised. It is quality controlled, ortho-geolocated (latitude and longitude coordinates, altitude) and annotated with satellite position and pointing, landmarks and preliminary pixel classification (e.g. land/water/cloud masks). Products are generated in FR (300 m) for the whole globe with the same coverage. This collection also provides SAR Radar Altimeter (SRAL) level-1 products and land products level-2 (SR_2_LAN) products and SLSTR products. |
