Les zones comprennent un secteur de 30 km² autour du puy de Dôme, le puy de Montaudoux, le Colombier et une densification à 20 points / m² sur le Kilian. Le modèle est découpé en 913 dalles géoréférencées d’emprise 250 x 250 m, au format LAZ, représentant un volume de 4,5 Go. Il se présente sous la forme d'un nuage de points en sortie d'acquisition, calé géométriquement et nettoyé des points aberrants. Ce semis de points a été acquis les 21-22 mars 2011 par le groupement d’entreprises GeoPhenix / GEOFIT Expert avec un capteur Leica ALS-50 II. La précision annoncée est de 8 cm en altimétrie (Z) et de 10 cm en planimétrie (XY). Données acquises dans le cadre du projet LiDARVERNE mené en partenariat entre le CRAIG, le Laboratoire Magmas et Volcans (LMV), le Laboratoire de Physique Corpusculaire (LPC), la Maison des Sciences de l'Homme (MSH) et l'Association Interrégionale pour la promotion du Patrimoine archéologique (AIP). Projet co-financé par l'Union européenne - Fond européen de développement régional FEDER - L'Europe s'engage en Auvergne. Initié dans l’optique du classement de la Chaîne des Puys au patrimoine mondial de l’UNESCO, ce produit a été réalisé parallèlement à une orthophotographie de 10cm de résolution. Ces données doivent à la fois permettre de mieux comprendre la structure des volcans (volcanologie), de surveiller leur activité et de faciliter l’identification de vestiges anthropiques (recherche archéologique).

ont été validées par la communauté scientifique de l'Université Blaise Pascal (Observatoire de Physique du Globe de Clermont-Ferrand (OPGC), Maison des Sciences de l’Homme de Clermont-Ferrand (MSH), Laboratoire de Physique Corpusculaire (LPC)) et l'Association Interrégionale du Patrimoine (AIP).\\nA l'issue de la phase d'acquisition, les données sont ajustées. Cette phase de traitement comprend :\\n- calcul précis des trajectoires de l'avion,\\n- calcul des semis de points laser basés sur la trajectoire,\\n- ajustement géométriques des bandes de vol (entre elles et par rapport aux surfaces de contrôles).\\nLe but de l'ajustement est d'homogénéiser les données LiDAR et d'éviter les artéfacts qui apparaissent dans les zones de recouvrements entre bandes lors de la classification des données.\\nPrincipaux paramètres de vol :\\n- hauteur de vol : 1000 m\\n- densité moyenne : 15 points/m²\\n- précision altimétrique des points laser mesurés (EMQ) : +/-0.08 cm\\n- précision planimétrique des points laser mesurés (EMQ) : +/-0.10 cm\\n\\nCe semis de points brut est ensuite filtré grâce à des algorithmes (par GeoPhenix) pour proposer d'autres produits :\\n- semis de points sol\\n- semis de points sol allégé\\n- semis de points sur-sol\\n- semis de points bâti\\n- semis de points végétation LAZ 1.2 GeoPackage ESRI Shapefile 1.0 ZIP CRAIG https://drive.opendata.craig.fr/s/opendata/download?path=%2Faltimetrie%2F2011_lidarverne&files=LiDARVERNE_2011_MoU.pdf WWW:DOWNLOAD-1.0-http--download Memorandum of Understanding Memorandum of Understanding signé par l'ensemble des partenaires https://opendata@drive.opendata.craig.fr/public.php/webdav/altimetrie/2011_lidarverne/01_TA/TA_LiDARVERNE_2011_LiDAR_L93.gpkg WWW:DOWNLOAD:GeoPackage TA_LiDARVERNE_2011_LiDAR_L93.gpkg Tableau d'assemblage des dalles sous forme de polygones au format GeoPackage.
