LASRead
Lidar or laser scanning data are often provided by vendors in binary LAS format. Though GIS softwares can be used to read in and display data, the attributes of the points are sometimes not accessible.
LASRead reads in files in LAS 1.1 format and outputs comma delimited text files with X coordinates, Y coordinates and Z coordinates (option 1), X coordinates, Y coordinates, Z coordinates and Intensity (option 2) or X coordinates, Y coordinates, Z coordinates, Intensity, Return number and Number of returns (option 3).
Large datasets (say, more than 3000000 points, depending on the system) may have to be split into smaller files to avoid errors related to available memory.
