This dataset provides a regional statistical grid with a 250-meter cell size, covering the Île-de-France region. It is published as part of the Île-de-France open data portal and maintained by the Institut national de l'information géographique et forestière (IGN), France's national mapping and geographic information agency. Such grids are typically used to aggregate and represent spatial data, such as population or land-use statistics, at a fine and consistent resolution, enabling comparison across different sources and supporting spatial analysis, planning, and cartographic applications within the region.Grille régionale au pas de 250M
