GEOSAT-2 Portugal Coverage 2021
GEOSAT-2 Portugal coverage is a collection of 2021 data over the Portugal area, including islands. The available dataset has a cloud cover less than 10%, and is acquired up to 1m resolution with Geometric accuracy <6m CE90 based on Copernicus DEM @10m. GEOSAT-2 Portugal 2021 - Spatial Coverage of the Dataset The following product types are available: 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; Bands: All, R-G-B or Ni-R-G Bundle: Panchromatic (1m resolution) + Multispectral bands (4m 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. Product Type Processing Level and Spatial Resolution L1B (native) L1C (ortho) Pan-sharpened 1.0m 1.0m Bundle (PAN+MS) 1.0m (P), 4.0m (MS) 1.0m (P), 4.0m(MS)

Space data unearths small-scale mining in Burkina Faso
Satellite data from ESA’s Pléiades Third Party Mission and Copernicus Sentinel-2 were used to demonstrate that deep learning models can accurately and inexpensively identify artisanal and small-scale mining, even in challenging semi-desertic environments.

European Cities: Cartosat-1 Euro-Maps 3D
A large number of European cities are covered by this dataset; for each city you can find one or more Cartosat-1 ortho image products and one or more Euro-Maps 3D DSM tiles clipped to the extent of the ortho coverage. The Euro-Maps 3D DSM is a homogeneous, 5 m spaced Digital Surface Model semi-automatically derived from 2.5 m Cartosat-1 in-flight stereo data with a vertical accuracy of 10 m. The very detailed and accurate representation of the surface is achieved by using a sophisticated and well adapted algorithm implemented on the basis of the Semi-Global Matching approach. The final product includes several pixel-based quality and traceability layers: The dsm layer (*_dsm.tif) contains the elevation heights as a geocoded raster file The source layer (*_src.tif) contains information about the data source for each height value/pixel The number layer (*_num.tif) contains for each height value/pixel the number of IRS-P5 Cartosat-1 stereo pairs used for the generation of the DEM The quality layer (*_qc.tif) is set to 1 for each height/pixel value derived from IRS-P5 Cartosat-1 data and which meets or exceeds the product specifications The accuracy vertical layer (*_acv.tif) contains the absolute vertical accuracy for each quality controlled height value/pixel. The ortho image is a Panchromatic image at 2.5 m resolution. The following table defines the offered product types.
