Abstract. Rockfall is a complex natural process that can present risks to the effective operation of infrastructure in mountainous terrain. Remote sensing tool and techniques are rapidly becoming the state of practice in the characterization, monitoring and management of these geohazards. The aim of this study is to address the methods and implications of how the dimensions of 3-dimensional rockfall objects, derived from sequential terrestrial laser scans (TLS), are measured. Previous approaches are reviewed, and two novel algorithms are introduced in an attempt to standardize the process. The approaches are applied to a set of synthetic rockfall objects generated in the open-source software package Blender. In addition, a database of close to 5000 rockfalls is presented derived from sequential TLS monitoring in the White Canyon, British Columbia, Canada. This study illustrates that the method in which the rockfall's dimensions are calculated has a significant impact on how the shape of a rockfall object is classified. This has implications for rockfall modelling as the block shape is known to influence rockfall runout.

Short summary
In mountainous regions around the world rockfall pose a hazard to infrastructure and society. To aid in our understanding and management of these complex hazards, an inventory can be compiled. 3D remote sensing data can be used to locate the source zones of these events and generate models of the areas which detached. We address the way in which the shape of a rockfall object can be measured. The shape of a rockfall has implications for forward modelling of potential runout zones.
