Abstract. As routing applications become common on mobile devices, significant problems that remain are the sparse underlying data support for pedestrian-based routing and the inability to customize an existing route for specific individual accessibility needs. Cartographic researchers have repeatedly demonstrated methods for sophisticated modelling of infrastructure and have built routing portals and accessibility systems, yet these systems and their benefits have not been used widely, due to problems with underlying data support. This research reviews a few exemplar systems and presents a new routing study that uses the presence of overhead tree canopy to add a preference layer to individual routing. This allows individuals to plan and choose navigation pathways for purposes of body heat thermoregulation, a problem that exists for many individuals with mobility impairments, particularly those with spinal cord injuries. The study presented here demonstrates that successful routing underneath the tree canopy can be done in a way that only marginally increases the length of such routes. This study also demonstrates the need for detailed geographic data support for preference-based routing.
