The GEOSat products are freely accessible in accordance with ESA’s Earth observation data policy. An active EO Sign In account is required to download the products.

In ESA's Third Party Missions (TPM) dissemination service and catalogue the data is collection based and allows data browse and download through the treeview as well as via geographical search using a static map.

GEOSAT products can also be discovered through ESA's EO Catalogue (EO CAT), which allows users to browse and download products among the available datasets from ESA and Third Party Missions and instruments, using various criteria (spatial, temporal).

New users can register an account on EO Sign In. For further information about the EO Sign In Service you can visit TellUs.

Should you need support to access the data, please contact EOHelp.

Description

GEOSAT-1 and 2 dataset is composed of products acquired by the GEOSAT-1 and GEOSAT-2 Spanish satellites. The dataset regularly grows as ESA collects new products.

GEOSAT-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 together.

GEOSAT-1 products are available in two 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 metres 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).

GEOSAT-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 acquired by the panchromatic sensor.
  • Multispectral (HRA_MS4): a four-band image acquired by 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.

GEOSAT-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.

Spatial coverage: Check the spatial coverage of the collection on a map available on the Third Party Missions Dissemination Service.
