▶ LiDAR LAStools with QGIS. Create DEM and Contour lines.

This minicourse consist in 3 video tutorials. In the first one, you are going to learn how to create a Digital Elevation Model (DEM) with QGIS using data from Google Earth. In the second one, you are going to learn how to use LASTool to process LiDAR data to create a DEM with QGIS. Also, you are going to see how to get the contour lines from both models. The third one is going to be a comparison between the two models and we will have a discussion about the accuracy of the ground elevation from Google Earth data.


▶ What you are going to learn in Part 2:

✔ Where downloading the LAStools
✔ Setting up LAStools in QGIS 3.10 A Coruña
✔ Download LiDAR data and checking metadata
✔ Analyzing LiDAR data: lasinfo
✔ Visualizing LiDAR data 3D: lasview
✔ Creating DEM: las2dem and blast2dem
✔ Visualizing DEM 3D
✔ Contour lines extraction
✔ Labeling and symbology
