Showcasing ESA's HEDAVI Earth observation tool
ESA's HEDAVI (HEritage DAta VIsualiation) is a platform that allows users to freely access over 40 years of ESA Earth observation Heritage, Third Party Missions and some Copernicus data.
New version of Third Party Missions data access guide
ESA’s Third Party Missions data access guide is now updated, providing the details of the latest data collections and changes to existing datasets.
Easy visualisation of Earth observation data with new HEDAVI tool modes
The Discover mode in HEDAVI showcases the usefulness of Earth Observation (EO) data in a variety of applications through a list of case-studies—so-called “stories”. The first new feature allows users to share links to the stories in HEDAVI. The second new feature allows them to export any image of a case-study from the Discover mode to the Explorer mode.

HEDAVI Discover: a step-by-step guide
The Heritage Data Visualisation tool (HEDAVI) is a platform developed by the French Science Consulting for Earth Observation group, VisioTerra, which allows users to freely access over 40 years of ESA Earth Observation Heritage data, Third Party Missions and some Copernicus data.
Discover Earth like never before: the HEDAVI tool
The Heritage Data Visualisation tool, or HEDAVI, enables the analysis of global spatio-temporal dynamics of natural and artificial environments, covering over 40 years of ESA Earth Observation Heritage data, Third Party Missions and some Copernicus data.
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.
New collections available: Cloud Free Landsat-5 TM and Landsat-7 ETM+ European and Mediterranean Countries
Two new data collections, Landsat-5 TM Cloud Free and Landsat-7 ETM Cloud Free collections, are available through the ESA Third Party Missions programme.
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.
Full European Landsat data collection now available under the same catalogue
The Full European Landsat data collection, from Landsat-1 to Landsat-8, is now available under the same catalogue
Timeline to over 40 years of historical satellite missions
ESA's Heritage Space Programme preserves historical data from over 40 years of Earth observation missions.
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
EDAP
The ESA Earthnet Data Assessment Pilot (EDAP) project will perform assessments for various missions to ensure the delivered data is fit for purpose.
SLAP
The SLAP (Systematic Landsat Archive Processing) project covers the MSS, TM and ETM+ products from Landsat missions 1 – 7, and is the first systematic reprocessing of the ESA Landsat archive.
HEDAVI
The HEDAVI (HEritage DAta Visualisation) service enables users to discover a wealth of heritage data from ESA's ERS and Envisat missions, as well as from Landsat-5 and Landsat-7.
