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.

New cross-calibration readies PROBA-1 data for climate research

While PROBA-1 has already exceeded expectations by suppling over 21 years of Earth observation hyperspectral data, recent cross-calibration activities are aiming to ensure the data will robustly serve long time-series research, even when the satellite ends operations.

Data - Data Description

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

This document describes the algorithms, radiometric and geometric processing of the European Space Agency (ESA) Landsat Multispectral Scanner (MSS), Thematic Mapper (TM) and Enhanced Thematic Mapper Plus (ETM+) products. It is intended to point towards useful resources for more information rather than provide full descriptions of the specific algorithms used during the processing.
