    Cloud-free collections key for land monitoring

    Satellite imagery is a crucially important tool for monitoring the land, but cloud cover can often block parts of Earth’s surface from view, limiting subsequent analyses.

    Commercial and international data for fire monitoring

    As climate change sparks a surge in the frequency and intensity of wildfires, satellite data disseminated through ESA’s Third Party Missions (TPM) programme are helping scientists to track and investigate these potentially damaging natural events.

    Landsat 7 ETM+ European and Mediterranean Countries Cloud Free Collection

    This dataset contains the cloud-free products from Landsat 7 Enhanced Thematic Mapper collection acquired over Europe, North Africa and the Middle East; for each scene only one product is selected, with the minimal cloud coverage. The Landsat 7 ETM+ scenes typically cover 185 x 170 km. A standard full scene is nominally centred on the intersection between a Path and Row (the actual image centre can vary by up to 100 m). The data are system corrected.

    Landsat ETM+ ESA archive

    This dataset contains all the Landsat-7 Enhanced Thematic Mapper high-quality ortho-rectified L1T products (or L1Gt where not enough GCPs are available) over Kiruna, Maspalomas, Matera and Neustrelitz visibility masks. The Landsat-7 ETM+ scenes typically covers 185 x 170 km. A standard full scene is nominally centred on the intersection between a Path and Row (the actual image centre can vary by up to 100 m). Each band requires 50 MB (uncompressed), and Band 8 requires 200 MB (panchromatic band with resolution of 15 m opposed to 30 m). Kiruna, Maspalomas and Matera Landsat-7 ETM density maps

    Proceedings of the workshop held from 12-14 October 2004 at ESA-ESTEC (Noordwijk, The Netherlands). The objective of the workshop was to present and exchange experiences and knowledge from work on inter-comparing large scale optical sensors at different product levels. This includes the evaluation and reduction of calibration bias and the validation of geophysical product uncertainties.
