This dataset provides classified LiDAR point cloud data of vegetation (ground/soil points after filtering), acquired between April and June 2018 by the SETIS/IMAO consortium using an IGI LiteMapper 7800 sensor, published by the Centre Régional Auvergne-Rhône-Alpes de l'Information Géographique (CRAIG). Flight parameters included an 850 m flight height, 110-knot speed, 60° scan angle, altimetric accuracy of 8 cm, and planimetric accuracy of 10 cm, with point density between 16 and 24 pts/m² (about 10 pts/m² after classification). Coverage spans 25 sites across five departments: Puy-de-Dôme, Allier, Loire, Haute-Loire, Ardèche, Rhône, and Isère, mostly natural areas such as peat bogs and marshes.”Production of a seedling of filtered points of vegetation by Lidar acquisition method. The acquisitions were made by the group of companies SETIS / IMAO. Date of acquisition: from 1/04/2018 to 23/06/2018 Laser: IGI Lite Mapper 7800 The parameters of the LIDAR flight are as follows: Flight height: 850m/floor Flight speed: 110 knots Scan angle: 60° Altimeter accuracy (standard deviation): 8 cm Planimetric accuracy (standard deviation): 10 cm Emission density between 16pts/m² and 24 pts/m² Average density of soil points after classification: 10 pts/m² The territory covered represents 25 areas: - 9 in the Puy de Dôme: La Godivelle (7/04/2018 + 11/05/2018), Jouvion (23/06/2018), Le Fossat (24/05/2018 + 5/06/2018 + 22/06/2018), Lac de Bordes (7/04/2018 + 11/05/2018), Sancy (22/06/2018 + 23/06/2018), Méjanesse (7/04/2018), Chavanon (7/04/2018), Cheire de Volvic (7/04/2018), Forion (1/04/2018) - 2 in the Allier: Echassières (1/04/2018), RN Val d’Allier (6/04/2018) - 4 in the Loire: Pivadan – Petite Bazanne (6/05/2018 + 22/06/2018), Marais du Gand (05/04/2018), RNR Colleigne (6/05/2018 + 24/05/2018 + 22/06/2018 + 23/06/2018), Valorges (5/04/2018) - 1 in the Haute Loire: Marais de Limagne (1/04/2018) - 1 in the Ardèche: Rieutord (1/04/2018 + 11/05/2018) - 5 in the Rhône: Tourbière du Couty (7/04/2018), Sous-les-Echarneaux (7/04/2018), Les Mouilles (7/04/2018), Filatures Amont (7/04/2018), Goutte Noire (7/04/2018) - 3 in the Isère: Chambaran (5/05/2018), Tourbière du Grands Lemps (27/04/2018 + 5/05/2018), Burette (5/05/2018).
