Algorithms for estimating the suitability of potential landing sites

Nils Egil Søvde


Cable yarding systems are commonly used in steep or difficult terrain and require suitable landing sites. This work describes two algorithms that calculate the suitability of roads and areas for landing site use. The algorithms were tested against real world data. The results show that simple algorithms are sufficient to make stable, useful estimates that are comparable with human site placements.  These techniques can be used to guide forest road network planning or reuse of existing roads.
