Preserving the bocage network

Hedgerows are excellent levers for the resilience of territories to climate change and for maintaining biodiversity. EagleHedges has developed operational tools for monitoring and characterizing the bocage network using Earth observation images and very high-resolution 3D models, in order to make up for the lack of reliable, recurring data on the state of the French bocage. The project team is working to extend the tool to other territories and, as new needs arise, to extend its functionalities.

🟢 HedgeTools, the hedge characterization tool, is available as an open-source QGIS plugin.

🔵 Automatic hedge detection service available on request.

Identify and visualize agricultural wasteland

The Izifriche solution is a comprehensive support service for the identification and visualization of agricultural wasteland, aimed at local players wishing to act for the resilience of their territory.

Developed as part of the SCO FrichesAgricoles project, the method for automated identification of wasteland is based on the use of geographical and satellite data analyzed by the WaSaBI ©CNES software's Artificial Intelligence, at the scale of the entire Occitanie region (France). The parcel data from the regional inventory of wasteland is used in a web interface equipped with numerous geographic databases, providing a global vision of the issues at stake at different territorial scales (commune, inter-commune, département).

🔵 Service marketed by Safer Occitanie from June 2024.

Monitoring changes in the mountain environment

Faced with the colonisation of moorland to the detriment of Alpine meadows, the Orion project has used satellite imagery to develop a detailed map (10 m) of natural habitats as well as fauna and flora indicators, including grazing area.

Replicable and scalable, the method is particularly well suited to managers of these areas, which are undergoing major changes to protect the environment as well as pastoral and tourist activities. It also offers very interesting prospects for understanding and preserving the ecosystems that emerge when glaciers retreat.

Thermography of cities from space

A pioneering project to learn how to use satellite thermal data in cities, Thermocity has delivered a collection of analysis-ready-data thermal images. This collection has been used to generate 4 major product families:

• Evolution of impermeability/artificialization and characterization of vegetation in the city;
• Detection and characterization of thermal anomalies;
• Mapping urban heat islands and diagnosing vulnerability to the associated heat ;
• Urban climate modelling: cross-validation and future climate.

Identifying the vulnerability of urban environments during summer heat waves

Developed in the cities of Lille (France) and Rayong (Thailand), the project has established a methodology for classifying local climate zones derived exclusively from very high-resolution satellite images.

The issues identified are the vulnerability of urban environments during summer heat waves, and the adaptation and mitigation of local heat peaks.

🟢 The application's coding is open-source on Cerema's github and can be transposed to any city. Shapefile files for Lille and Rayong are available to download in the Resources section of the project page.

Monitoring tropical deforestation

The Tropisco platform provides a near-real-time view of tropical deforestation from 2018 to the present day. Its maps of forest cover loss are updated every 6 to 12 days using radar images from the Copernicus Sentinel-1 satellite.

Aiming for global coverage, Tropisco currently monitors the forests of 7 countries (French Guiana, Suriname, Guyana, Gabon, Vietnam, Laos and Cambodia), which were used to develop the tool.

Satellite surface soil moisture

Developed in Brittany, where geology makes water supply dependent on surface water, BOSCO lays the foundations for a spatial observatory of soil water content.

The interface displays three key pieces of information at very high spatial resolution (plot) and temporal resolution (2-3 days), which are crucial for farmers and water managers: surface moisture (first 5 cm of soil), root water content (one metre deep) and recharge (or water flow) towards the water table.

Supporting solutions based on urban vegetation

Supported by Cerema, the GUS project has developed a method for fine mapping urban vegetation in order to better assess its many ecosystem services. The results obtained in Greater Nancy are available online on the Landia platform (ex Green City) operated by TerraNIS. This platform offers summary indicators at different grids (hexagonal, urban morphological island, IRIS, municipalities, etc.), data explorers and summary dashboards.

🟢 Access to the Nancy demonstrator is open.

🟢 Based almost entirely on THR satellite images, the method can be replicated for any town => the algorithmic codes are available on Cerema's Github.

Climate and environmental monitoring for early health warnings 

As many diseases are strongly linked to their environment, monitoring environmental and climatic dynamics can help predict their dynamics in space and time.

ClimHealth, an online early warning system, is a generic interface that can be adapted to any location, making it possible to visualize possible links between temporal and spatial epidemiological dynamics and those of rainfall, temperature or environmental indicators (such as water, vegetation or humidity indicators).

🟢 Free access. The codes for the application and the Sen2Chain processing chain are open source.

Developed for a single disease, leptospirosis in Yangon (Myanmar), the first demonstrator LeptoYangon can also be viewed online.

Predictive mapping of Aedes mosquito population densities

Aimed at Regional Health Agencies (ARS) and mosquito control operators, the Arbocarto-V2 application generates predictive maps of the abundance of Aedes albopictus or aegypti mosquitoes in a given area, depending on the user's choice, and can be used to simulate different prevention or control scenarios.

The tool is accompanied by a user manual and a methodological guide for creating or updating environmental data from satellite images.

🟢 Arbocarto is free software in .exe format, and can be requested from the Ministry of Health, which owns the tool, using the form available here. 

Improving resilience to extreme hydro-meteorological events

Developed as part of the FLAude project, FORO uses satellite observation to improve the resilience of areas to the risks of flooding caused by intense run-off.

A genuine decision-making tool, FORO offers interactive maps to pinpoint problem areas and the levers for action. FORO is gradually being rolled out across the 23 departments of the Mediterranean Arc.
