"Route schematization with landmarks";
Journal of Spatial Information Science, 21 (2020).

Modern navigation applications make use of a turn-by-turn instructions approach
and are mostly supported by digital devices with limited display size. This combination
does little to improve users´ orientation or spatial knowledge acquisition. Considering
this limitation, we propose a route schematization method to facilitate the readability of
route information and survey knowledge acquisition. Current schematization methods focus
on the route path and ignore context information, specially polygonal landmarks such
as lakes, parks, and regions, which is crucial for promoting orientation. Our schematization
method, in addition to the route path, takes as input: adjacent streets, point-like landmarks,
and polygonal landmarks. Moreover, the schematic layout highlights spatial relations between
route and context information, improves the readability of turns at decision points,
and the visibility of the surroundings. The focus of the paper is the schematization method
that combines geometric transformations and integer linear programming to produce the
maps. Two routes are used as examples to present the execution information and the outputs.
We complement our results with a user study that indicates a preference for our
schematic layout in matching textual route instructions. The contribution of this paper is a
method that produces schematic route maps with context information to support the user
in wayfinding and orientation.
