The airborne laser scanners
LMS-Q560i and LMS-Q680 digitize the waveform capability of the echo signal for every emitted laser pulse. RiANALYZE applies the so-called Full Waveform Analysis to the digitized echo signals provided by the laser scanner and additionally transforms the geometry data (i.e., range and scan angle) into Cartesian coordinates. Thus, RiANALYZE converts the digitized echo signal data to data compatible with conventional airborne laser data processing packages for further processing.
The output is a point cloud in the well-defined Scanner's Own Coordinate System (SOCS) with additional descriptors for every point, e.g., a precise time stamp, the echo signal intensity, the echo pulse width, a classification according to first, second, up to last target.
Different approaches have been proposed for performing the full waveform analysis of digitized echo signals of an airborne laser scanner. RiANALYZE implements three different algorithms which can be used alternatively allowing the user to optimize processing time or processing accuracy.
Additionally, RiANALYZE is smoothly integrated into the project-oriented processing software RiPROCESS via the application RiSERVER
