Environment and satellite data: from abundance of applications to the surge of structured solutions
Chaired by Laurent Boisnard, Deputy Head of Earth Observation, CNES and
François Robida, BRGM
Satellite data for urban growth
 |
The 'Urban Space Series' product developed in partnership with ESA, the World Bank and QuantCube Technology is an AI platform for characterizing land, and specifically for detecting the urban area of the city, based on satellite images. Knowledge of urban development is a key element for the main players in the real estate market (real estate investors and large companies making long-term strategic investments) as well as for urban planners and public institutions.
For this, we have developed a methodology based on the analysis of Sentinel-2 images available with a spatial resolution of 10 m: the product 'Urban Space Series' allows to measure the evolution of the shape and size of the zones from satellite images. For the development and implementation of the 'Urban Space Series' solution, it was necessary to develop a robust algorithm capable of analyzing the large amount of data in satellite images. The algorithm is currently able to manage different topologies, densities and types of city construction. Indeed, cities have different infrastructures across continents, the fields can also be very different depending on the region and the season: all these different characteristics of cities must be learned in the training package.
Finally, we will share a major area of improvement in the years to come through our participation in the AI4GEO project, by integrating the analysis of 3D data allowing us to go to a more granular level on the characterization of cities.
This session will focus on how Sentinel-2 satellite data can measure changes in the shape and size of urban areas that are difficult to measure with traditional statistics.
