LAZ files are an compressed LiDAR data format and are often used when transferring large amounts of LiDAR data. GeoNB uses this format to provide LiDAR data in New Brunswick. LAZ files need to be converted to LAS files before they can be processed in ArcGIS. These instructions describe how to covert LAZ files using the open source LASzip tools developed by Martin Isenburg.
- Download LASzip: Go to http://www.laszip.org/ and download the exe file located in the Background section
- Save the file to the directory where the LAZ files are located
- Using windows command prompt, navigate to where the exe and LAZ files are located
- Type: laszip *.laz
- All of the LAZ files will now be converted to LAS files and saved in the same directory with the same file name but with the LAS extension
