Space data support Earth’s ecosystems
ESA’s Earth observation (EO) missions are making a critical contribution to monitoring transformations in our planet’s ecosystems, helping track changes in the vegetation, soil, and ocean that affect these systems.

GEOSAT-2 Spain Coverage
The GEOSAT-2 Spain Coverage collection consists of two separate coverages of Spain, including the Balearic and Canary islands, acquired by GEOSAT-2 between March and November of 2021 and 2022, respectively. The available imagery have a geolocation accuracy of < 4 m RMSE, a cloud cover percentage of < 10 %, and were acquired at an off-nadir angle from -30° to 30°. Spatial coverage of the 2021 collection. The following product types are available: Pan-sharpened: A four-band image, resulting from adding the information of each multispectral band to the panchromatic band. The fusion does not preserves all spectral features of the multispectral bands, so it should not be used for radiometric purposes. Resolution 1 m; Bands: All. Bundle: Panchromatic (1 m resolution) + Multispectral bands (4 m resolution): five-band image containing the panchromatic and multispectral products packaged together, with band co-registration. The available processing level is L1C orthorectified: a calibrated and radiometrically corrected product, manually orthorectified and resampled to a map grid. Property Spatial Resolution Pan-sharpened 1.0 m Bundle (PAN + MS) 1.0 m (PAN), 4.0 m (MS)

GEOSAT-1 and 2 ESA archive
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. As per ESA policy, very high-resolution imagery of conflict areas cannot be provided.

GEOSAT-2 full archive and tasking
GEOSAT-2 full archive and new tasking products are available in different bands combinations: Pan-sharpened (4 bands, 321 Natural Colours or 432 False Colours): A four-band image, resulting from adding the information of each multispectral band to the panchromatic band. The fusion does not preserves all spectral features of the multispectral bands, so it should not be used for radiometric purposes. Resolution 1m (L1B), 0.75m (L1C) or 0.40m (L1D); Bands: All, R-G-B or Ni-R-G Panchromatic: Single-band image coming from the panchromatic sensor. Resolution 1m (L1B) or 0.75m (L1C) Multispectral: Four-band image coming for the multispectral sensor, with band co-registration. Resolution 4m (L1B) or 3m (L1C) Bundle: Panchromatic + Multispectral bands: five-band image containing the panchromatic and multispectral products packaged together, with band co-registration. Resolution 1m+4m (L1B), 0.75m+3m (L1C) or 0.40m+1.6m (L1D); And in addition: Stereo Pair: 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. The image products are delivered in GeoTIFF image format by default. JPEG-2000 format is also available on demand. Available processing levels are ortho-ready L1B (not resampled) and ortho L1C (orthorectified and resampled ). In addition, for Pan-sharpened and Bundle, also L1D (enhanced ortho) super-resolution products are available: based on artificial intelligence, this technology increases the original resolution and detail of an image without losing quality with respect to the original product. Product Type Processing Level and Spatial Resolution Spectral Bands L1B (orthoready) L1C (ortho) L1D (Enhanced Ortho) Pan-sharpened 1.0 m 0.75 m 0.4 m All R, G, B NI, R, G Pan 1.0 m 0.75 m Only Pan band MS 4.0 m 3.00 m Only MS band Bundle (PAN+MS) 1.0 m (P), 4.0 m (MS) 0.75 m (P), 3.0 m (MS) 0.4 m (P), 1.6 m (MS) All As per ESA policy, very high-resolution imagery of conflict areas cannot be provided.
