RiWORLDfor RIEGL Scan Data•• transformation of laser scan data
into the coordinate systemof the trajectory••use of geometrical systemdescription and calibration
information (lever arms)••supporting different formats ofposition and orientation data

Airborne and Mobile Laser Scanning Systems
provide data acquired by the laser scanner(s) anddata from an INS/GNSS system. The laser scanner data is frequently referred to as scan data,
whereas the INS/GNSS data or position and orientation data is called in short trajectory data after postprocessing.

••interfacing to third party softwarepackages

RiWORLD transforms the scan data into the coordinate reference••smoothly integrated into RiPROCESS
project management software

It thus provides the acquired laser data of the object‘s surfaces

system of the trajectory, usually WGS84 (world geodetic system).
within a geocentered coordinate system for further processing.
In order to transform the scan data with high accuracy RiWORLD
applies accurate geometrical system descriptions as input, i.e.,
the transformations from the scanner system to the INS/GNSS
coordinate system, and to the vehicle body coordinate system.
The output data of RiWORLD represents a point cloudin the trajectory‘s coordinate reference system withadditional descriptors for each point such as
amplitude of echo return, target reflectance,echo pulse width, pre-classification, andmore. RiWORLD is smoothly integrated into
the project-oriented processing software
RiPROCESS via the application server
RiSERVER.

Data SheetData Acquisition with Airborne and Mobile Laser Scanning Systems
An airborne laser scanner system (ALS system) or a mobile laser
scanner system (MLS system), respectively, comprises two maincomponents:
at least one laser scanner for acquiring dimensional measurements, i.e. 3D information, on the surface of the scanned objects
andan INS/GNSS (inertial navigation system andglobal navigation satellite system) subsystem for acquiring position and orientation of the platform within a global coordinate system.

RiWORLD transforms the laser scan into a global earth-centeredearth-fixed (ECEF) coordinate reference system (e.g. WGS84) bymeans of the provided trajectory data, mounting orientation,and boresight adjustment parameters.
