Les zones comprennent notamment un secteur de 385 km² sur la chaîne des Puys, la Dombes (2750 km²) et le cours de la Loire dans le département éponyme (181 km²). Le modèle est découpé en 14331 dalles géoréférencées d’emprise 500 x 500 m, au format LAZ, représentant un volume de 846 Go. Il se présente sous la forme d'un nuage de points colorisés et triés en 8 classes : - points non-classés (1) - sol (2) - végétation basse (3) - végétation moyenne (4) - végétation haute (5) - bâtiments (6) - bruit (7) - tablier de pont (10) - éléments divers (11) - points virtuels (13). Ce semis de points a été acquis entre février et avril 2021 par le groupement d'entreprises Avineon / APEI avec des capteurs Leica CityMapper-2 / Hyperion 2+ et Leica TerrainMapper / Hyperion. La précision annoncée est de 8 cm en altimétrie (Z) et de 15 cm en planimétrie (XY). Données acquises dans le cadre d'un partenariat entre : - le CRAIG - le Département de l'Ain (CD 01) - le Département de l'Allier (CD 03) - le Département de la Loire (CD 42) - Montluçon Communauté - le Conservatoire des espaces naturels Rhône-Alpes (CENRA) - le Conservatoire des espaces naturels d'Auvergne, - la Fédération française de course d'orientation (FFCO) - le Laboratoire Magma et Volcans (LMV) - le Centre d'Histoire “Espaces & Cultures” (CHEC) - la Direction Régionale des Affaires Culturelles (DRAC) - la commune du Lac-d'Issarlès - Archéo-Logis - CDERAD, - l'association Tolvedunum, - le Groupe de Recherches Archéologiques de la Loire (GRAL), - le Groupe de Recherche Archéologique Vellave (GRAV), - l'Agence de l'Eau Rhône Méditerranée Corse, - les communautés de communes de la Côtière à Montluel (3CM), de la Dombes et de Dombes Saône Vallée (CCDSV) - les syndicats de rivières SIGAL 15, SBVR, SMVV, SR3A et SRDCBS. Les données ont été acquises pour répondre à des programmes d’études dans les thématiques suivantes : - Archéologie : Etude de traces d’occupation de toutes périodes : oppida et autres fortifications, agglomérations, sanctuaires, voies, nécropoles, parcellaires, enclos, habitats ruraux, aménagements hydrauliques, carrières et mines, charbonnières, etc. - Géomorphologie et géographie environnementale.
