French cities, which lack green space and vegetation, are warmer than the surrounding countryside. Worried about the well-being of its inhabitants, Grand Lyon launched a project in 2018 to identify natural spaces within the urban areas in order to preserve them. To do so, Grand Lyon chose SIRS, subsidiary of CLS Group and expert in geographical data for 30 years.\u00a0 The work done by SIRS makes it possible for Grand Lyon to precisely identify the vegetation within its limits in order to define conservation and rehabilitation measures and adapt to climate change.\u00a0<\/strong><\/p>\n<p><strong>Sustainable urban management <\/strong><\/p>\n<p>The Grand Lyon is an administrative district made up of 59 townships.
