DESCRIPTION:As part of the national LiDAR HD program\, IGN (French National
  Institute of Geographic and Forest Information) produces a 3D description
  of the French territory using LiDAR data\, and distributes it in the form
  of point clouds and digital models.  \n \nThe 3D point clouds captured as
  part of this program are first segmented into several classes (ground\, w
 ater\, vegetation\, buildings\, bridges\, etc.)\, then  transformed into D
 TM (digital terrain models)\, DSM (digital surface models) and DHM (digita
 l height models).\n \nTo meet this challenge\, IGN development teams have 
 set up a processing chain based on Open-Source libraries (pdal\, gdal\, pr
 oj\, etc.) and developed their own tools (A.I. classification\, DTM and DS
 M derivation\, thematic map calculation\, water surface processing\, etc.)
 \, most of which are Open-Source.\n \nIn detail: \n* Myriad 3D: classifica
 tion of point clouds using AI (https://github.com/IGNF/myria3d)\n* Coclico
 : classification results comparison tool\, agnostic of classification tool
 s. (https://github.com/IGNF/coclico)\n* CtView: calculation of thematic ma
 ps from point clouds (class maps with shading\, density maps\, etc.). (ava
 ilable soon)\n* Lidro: treatment of watercourses in a lidar point cloud (t
 o guarantee watercourse flow) (https://github.com/IGNF/lidro)\n* GPAO : di
 stribution and scheduling system for calculation (https://github.com/ign-g
 pao)\n* ...\n \nIn this talk\, we propose to first describe the whole proc
 ess\, then delve into the Open-Source software components we have designed
  and the uses of the OSGeo Open-Source libraries (pdal\, gdal\, proj\, ...
 ) we make in those tools.
