How is LIDAR data processing with lastools and QGIS 3?
LiDAR Data Processing with LAStools and QGIS 3. Light Detection and Ranging (LiDAR) is a spatial data acquisition method that used laser light and specialized GPS receiver. LiDAR surveying activity will produce millions of point which is called point cloud that consist of X,Y and Z information.

How to create DEM from lidar data using lastools?
To create DEM from LiDAR data using LAStools can be done using las2dem or las2demPro. las2dem is a single file processing tool. On the other hand las2demPro is multiple files processing within a folder. Because we have some files form previous split process, then las2demPro is a right choice.
How to merge all the tiles in GDAL?
If the area if not large enough and could be rendered smoothly, merging all the tiles is a good approach. To merge all the tiles can be used GDAL Merge tool. To find the tool type merge in the Processing Toolbox searching option, and look at the tool below GDAL tool as shown in figure 13.
How to clip multiple lidar tiles in ArcGIS?
As from ArcGIS Desktop 10.4 (and ArcGIS Pro) one can use the Extract LAS tool (requires 3D Analyst) for clipping a LAS Dataset with vector data. From ArcGIS, it is only possible to clip multiple LiDAR tiles with the LAStools Production toolbox.
Where are the lidar tiles stored in lastile?
Create a new folder called ‘.\\LAStools\\bin iles_raw’ for storing the LiDAR tiles. Then run ‘lastile.exe’ in GUI mode and load the 7 example flight strips. You can either do this by double-clicking ‘lastile.exe’ and using the ‘browse …’ menu or by entering the command below:
Where does the data go in QGIS 3?
Extract it and then copy to a drive. For Windows operating system, the default location is in drive C. If you place it in another drive, then you have to set the path in QGIS. I will show you how to do it just in a minute.
