Abstract
Predominant navigation applications make use of a turn-by-turn instructions approach and are mostly supported by small screen devices. This combination does little to improve users' orientation or spatial knowledge acquisition. Considering this limitation, we propose a route schematization method aimed for small screen devices 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, our schematic route map layout highlights spatial relations between route and context information, improves the readability of turns at decision points, and the visibility of survey information on small screen devices. The schematization algorithm combines geometric transformations and integer linear programming to produce the maps. The contribution of this paper is a method that produces schematic route maps with context information to support the user in wayfinding and orientation.

We asked all members of our editorial board to write vision pieces showing the diversity of ways in which our field can contribute to both basic science and major societal challenges
Some editorial board members chose to write their piece alone; others asked colleagues to contribute. These are diverse, and they span a range of topics
Summary
JOSIS, as Mike Worboys put it in his editorial introducing the first issue ten years ago, is “an online publication and all articles are free to access for any person” [17]. Climate change has become a climate emergency, biodiversity and nature’s contributions to people have been recognized as important contributors to Sustainable Development Goals1, easy access to locationenabled devices in many people’s pockets has changed the way that societies operate, and most recently, a global pandemic has impacted on all of our lives. All of these events bring into sharp focus the ways in which the data, technologies, and methods we work on can be used for good.
