  • Deimos-1 and 2 ESA archive

    https://cmr.earthdata.nasa.gov/search/concepts/C1965336826-ESA.xml
    Description:

    Deimos 1&2 dataset is composed of products acquired by the Deimos 1 and Deimos 2 Spanish satellites.DEIMOS-1 standard products offered are:• SL6_22P: SLIM6, 22m spatial resolution, from bank P• SL6_22S: SLIM6, 22m spatial resolution, from bank S• SL6_22T: SLIM6, 22m spatial resolution, 2 banks merged togetherDeimos -1 products are available in three different processing levels:-Level 1R: All 3 Spectral channels combined into a band-registered image using L0R data. Geopositioned product based on rigorous sensor model. Coefficients derived from internal and external satellite orientation parameters coming from telemetry and appended to metadata.-Level 1T: data Orthorectified to sub-pixel accuracy (10 meters RMS error approximately) with respect to Landsat ETM+ reference data and hole-filled seamless SRTM DEM data V3, 2006 (90 m). The use of the GCPs, it is not automatic, as it is done manually, which gives greater precision. (GCPs by human operators).-Level 2T: L1T product with value added product (RGB, NDVI, …)Deimos-2 standard products offered are:• Pan-sharpened (HRA_PSH four-band image, HRA_PS3 321 Natural Colours, HRA_PS4 432 False Colours): a four-band image, resulting from adding the information of each multispectral band to the panchromatic band. The fusion does not preserve all spectral features of the multispectral bands, so it should not be used for radiometric purposes.• Panchromatic (HRA_PAN): a single-band image coming from the panchromatic sensor.HRA_MS4: Multispectral (HRA_MS4): a four-band image coming for the multispectral sensor, with band co-registration.• Bundle (HRA_PM4): a five-band image contains the panchromatic and multispectral products packaged together, with band co-registration.• Stereo Pair (HRA_STP): The image products obtained from two acquisitions of the same target performed from different viewpoints in the same pass by using the agility feature of the platform. It can be provided as a pair of pan sharpened or panchromatic images.Deimos -2 products are available in two different processing levels:-Level 1B: A calibrated and radiometrically corrected product, but not resampled. The product includes the Rational Polynomial Coefficients (RPC), the metadata with gain and bias values for each band, needed to convert the digital numbers into radiances at pixel level, and information about geographic projection (EPGS), corners geolocation, etc.-Level 1C: A calibrated and radiometrically corrected product, manually orthorectified and resampled to a map grid. The geometric information is contained in the GeoTIFF tags.

  • TropForest - ALOS, Deimos-1 & KOMPSAT-2 optical coverages over tropical forests

    https://cmr.earthdata.nasa.gov/search/concepts/C1532648157-ESA.xml
    Description:

    The objective of the ESA TropForest project was to create a harmonised geo-database of ready-to-use satellite imagery to support 2010 global forest assessment performed by the Joint Research Centre (JRC) of the European Commission and by the Food and Agriculture Organization (FAO). Assessments for year 2010 were essential for building realistic deforestation benchmark rates at global to regional levels.To reach this objective, the project aimed to create a harmonised ortho-rectified/pre-processed imagery geo-database based on satellite data acquisitions (ALOS AVNIR-2, DEIMOS-1 SLIM6, KOMPSAT-2 MSC) performed during year 2009 and 2010, for the Tropical Latin America (excluding Mexico) and for the Tropical South and Southeast Asia (excluding China), resulting in 1971 sites located at 1 deg x 1 deg geographical lat/long intersections. The project finally delivered 1866 sites (94.7% of target) due to cloud coverages too high for missing sites
