PGIS7 : Point Cloud data processing, with PostGIS

Synopsis

This training session is dedicated to the manipulation and exploitation of huge cloud point data, such as data coming from LIDAR or information coming from mobile sensors (smartphones, transponders..)

The PDAL project and the PostgreSQL/PostGIS PointCloud extension are nowadays mature solutions to deal efficiently with point cloud data. This training session will allow you to discover these tools and use them to answer your point data processing needs.

Goals

The course will give you the following skills :

  • Know to import and export point cloud data
  • Be able to use point cloud data processing features
  • Know the performance issues regarding point cloud data

Duration
