▶️ Google Earth, LiDAR & DEM Model Comparison QGIS
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 3:
✔️ How to compare 2 models with a visual 3D interpretation
✔️ How to create a profile section of a DEM
✔️How to quantify numerically the differences of 2 DEM
✔️ How accurate is the Google Earth DEM compares with the LiDAR DEM
✔️ Google Earth, horizontal and vertical resolution, where the Metadata is?
✔️ Other source of information to create or download DEM
✔️ DEM, Contour Shape files and Raster topographic Maps created by government agencies
✔️ Comparison between DEM created by government agency with DEM created with data from Google Earth
✔️ Other topics related to scale and Google Earth Maps Resolution

Este tipo es Cubano.

When I open the 3d View of DEM , there surface appears flat rather than cubic which is in this video ? Also there is option of texture but not the resolution in properties

Looks like you did not created the DEM properly. Check if the pixels has values for the elevation or try to extract the contour lines.

Hi, Excelente video; I really love it and learned so much. I have a question: Can you recommend to me any website to download lidar point for free? Thanks

Thanks for your positive comment. Honestly, I cannot tell you, but it is not difficult to find it. Each country has free LiDAR data to share. Just make your on search. Good luck!
