Satellite data to enrich the analysis of the CASD

 

A partnership with the start-up company New Space Prométhée will make it possible to provide CASD users with a service offering precise data (soon to be of impressive accuracy and frequency) from satellite imagery. Through this information, the service aims to respond to the major global challenges of today, particularly in the fight against global warming, but not only…

These data, currently mainly derived from Sentinel satellite images of the European Copernicus space programme, will eventually come from Prometheus’ proprietary nanosatellites. These satellites, launched into space in 2023, will enrich the data thanks to their innovative characteristics: high resolution (1.5 metres per pixel), high revisit rate (several times a day) and optical technology that is both multispectral and hyperspectral, making it possible to precisely characterise environments (for example, distinguish between crop types and determine the health of fields in an agricultural context). These data are extracted from satellite images using remote sensing and are then cross-referenced with geolocalised socio-economic entities of interest (commune, settlement, administrative area, etc.), thus enabling economic evaluations to be carried out.

A detailed dataset, provided as an example, on six “emblematic” indicators of air quality at the municipal and facility level will be made available on the CASD:- suspended particulate matter (PM2.5, i.e. particles with a diameter of less than 2.5 µm)
– suspended particles (PM10, i.e. particles with a diameter of less than 10 µm)
– concentration of birch pollen
– grass pollen concentration
– concentration of mugwort pollen
– concentration of ragweed pollen

This service is accessible via a demonstrator by clicking on this link.

Customised datasets (period covered, temporal frequency or customised level of granularity, or additional indicators from Earth Observation relating to other themes such as greenhouse gas emissions, the state of the seabed, land and sea traffic, etc.) may be ordered for more specific needs.
