This document describes ESA's Earth observation End-User Access Policy to ESA and Third Party Mission Data, Tools and Resources.
Meet the Quality Assurance for EO Team
The Quality Assurance For Earth Observation (also known as QA4EO) Service began its operations on 1 November 2019, providing support to the Data Quality and Algorithms Management Office at ESRIN, within the Sensor Performance, Processing and Algorithm section.
Multi-frequency radar data from new campaign supports sea ice monitoring
A new dataset has been released for the CIRFAEx campaign, which took place off the coast of Greenland in 2022 to support the development of the upcoming ROSE-L and Sentinel-1 Next Generation missions.
CIRFAEx
From 22 April 2022 to 12 May 2022, the Norwegian research vessel Kronprins Haakon served as base for in-situ measurements and observations of sea ice and snow properties at Belgica Bank / North-East Greenland which is a region of highly variable ice cover characteristics and frequent occurrences of icebergs.
HEDAVI Tutorial: how to search for images in HEDAVI’s Explorer mode
The Explorer mode of the HEritage DAta VIsualisation tool (HEDAVI) allows users to process on-the-fly, visualise, share and export Earth observation data from ESA’s Heritage and Third Party Missions.
ALOS Optical Dissemination Service - Scheduled maintenance on 25 September 2024
A software maintenance activity has been scheduled for ALOS Optical Dissemination service on Wednesday 25 September 2024 from 07:30 to 08:00 UTC.
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.
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.
Go-to guide to Third Party Mission data offering
ESA’s latest Third Party Missions Data Access Guide has been published, providing technical details and information on available data collections for all current or past Third Party Missions.
How do I access the ESA Third Party Mission (TPM) data?
Access ESA Third Party Mission (TPM) data by applying with 'Fast Registration with Immediate Access' or 'Fast Registration with Approval.
How do I access the ALOS data services?
Access ALOS PALSAR and Optical data by registering on the respective data description page.
How to find the geographical and temporal coverage of the ESA TPM archive collections
Explore the ESA TPM archive collections, containing Earth Observation data from international partners, and learn how to discover their geographical and temporal coverage for research and pre-operational applications.
What is the ESA online On-The-Fly dissemination service?
Explore ESA's On-The-Fly dissemination service (L-OADS), featuring Third Party Missions and ESAR products enabling immediate downloads upon request with a valid EO Sign-In account.
What quality issues apply to the (A)SAR and ALOS PALSAR data?
Information on quality issues related to (A)SAR data, including specific disclaimers for Envisat ASAR and ALOS PALSAR products.
What are the Terms of Applicability?
Essential information about data ordering, accessibility conditions, and distribution constraints for TPM EO 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.
ALOS PRISM L1C
This collection provides access to the ALOS-1 PRISM (Panchromatic Remote-sensing Instrument for Stereo Mapping) OB1 L1C data acquired by ESA stations (Kiruna, Maspalomas, Matera, Tromsoe) in the ADEN zone, in addition to worldwide data requested by European scientists. The ADEN zone was the area belonging to the European Data node and covered both the European and African continents, a large part of Greenland and the Middle East. The full mission archive is included in this collection, though with gaps in spatial coverage outside of the ADEN zone. With respect to the L1B collection, only scenes acquired in sensor mode with a Cloud Coverage score lower than 70% and a sea percentage lower than 80% are published: Orbits: from 2768 to 27604 Path (corresponds to JAXA track number): from 1 to 665 Row (corresponds to JAXA scene centre frame number): from 310 to 6790. The L1C processing strongly improve accuracy compared to L1B1 from several tenths of metres in L1B1 (~40 m of northing geolocation error for Forward views and ~10-20 m for easting errors) to some metres in L1C scenes (< 10 m both in north and easting errors). The collection contains only the PSM_OB1_1C EO-SIP product type, using data from PRISM operating in OB1 mode with three views (Nadir, Forward, and Backward) at 35 km wide. Most of the products contain all three views, but the Nadir view is always available and is used for the frame number identification. All views are packaged together; each view, in CEOS format, is stored in a directory named according to the JAXA view ID naming convention.
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.
