Introduction to working with LiDAR data

March 16 @ 17:30 - 20:30

Free

Interested in LiDAR and 3D point clouds but don’t know where to start? In this workshop, you will see how these data sets are created.  You will then learn how to navigate in 3D space using CloudCompare and MeshLab.   Using basic OpenSource tools, you will find and filter out noise, classify ground points, segment a cloud and create a mesh as well as a raster based model (DEM).  In QGIS, you will manipulate the high-resolution ground and canopy level DEMs and produce great looking (but also useful) hillshade and slope models.

At the end of the workshop you will be able to

  • identify and work with various LiDAR file formats
  • manipulate a 3D Point Cloud file
  • build a raster based digital terrain model (DTM)
  • manipulate LiDAR data with different OpenSource software

Prerequisite: none, but familiarity with GIS is helpful

Requirement: before you come to the workshop, please have CloudCompare in its latest version installed. It is available for Windows, Mac and Linux at https://www.danielgm.net/cc/. Addtionally, you can, but don’t have to install QGIS (https://www.qgis.org).

This workshop will be hosted online on Zoom and takes about 2.5-3 hours.  Registration closes at 4 pm on the day of the workshop. You will subsequently receive the Zoom link and a link to download data. The instructor will be Nicolas Cadieux.
