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.

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.

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

SPOT 4-5 Take5 ESA archive

At the end of SPOT-4 mission, the Take5 experiment was launched and the satellite was moved to a lower orbit to obtain a 5 day repeat cycle, same repetition of Sentinel-2. Thanks to this orbit, from 1 February to 19 June 2013 a time series of images acquired every 5 days with constant angle and over 45 different sites were observed. In analogy to the previous SPOT-4 Take-5 experiment, also SPOT-5 was placed in a 5 days cycle orbit and 145 selected sites were acquired every 5 days under constant angles from 8 April to 31 August 2015. With a resolution of 10 m, the following processing levels are available: Level 1A: reflectance at the top of atmosphere (TOA), not orthorectified products Level 1C: data orthorectified reflectance at the top of atmosphere (TOA) Level 2A: data orthorectified surface reflectance after atmospheric correction (BOA), along with clouds mask and their shadow, and mask of water and snow. Spatial coverage: Check the spatial coverage of the collection on a map available on the Third Party Missions Dissemination Service.

SPOT 1-5 ESA archive

The ESA SPOT 1-5 collection is a dataset of SPOT 1 to 5 Panchromatic and Multispectral products that ESA collected over the years. The HRV(IR) sensor onboard SPOT 1-4 provides data at 10 m spatial resolution Panchromatic mode (-1 band) and 20 m (Multispectral mode -3 or 4 bands). The HRG sensor on board of SPOT-5 provides spatial resolution of the imagery to < 3 m in the panchromatic band and to 10 m in the multispectral mode (3 bands). The SWIR band imagery remains at 20 m. The dataset mainly focuses on European and African sites but some American, Asian and Greenland areas are also covered.
