Mental representations of spatial knowledge are organized hierarchically. Among people familiar with an urban environment, common spatial knowledge from these spatial mental representations enables successful communication of place and route descriptions, consisting of hierarchically-ordered references to prominent spatial features, such as streets. The more prominent a street is, the more like...

In this paper, we derive a topological pattern of urban street networks using a large sample (the largest so far to the best of our knowledge) of 40 US cities and a few more from elsewhere of different sizes. It is found that all the topologies of urban street networks based on street–street intersection demonstrate a small world structure, and a scale-free property for both street length and c...

Over the past years, user-generated content has gained more prominence in the area of geographic information science. In many geo-spatial applications, sketch maps are considered an intuitive user interaction modality. As typically only qualitative relations are persevered in sketch maps, processing spatial information on qualitative level has been suggested. The information represented in sket...

Coastal cities in the Adriatic and Ionian region are studied according to three evolution stages spanning from the end of eighteenth century to the present. The urban growth during this period has occurred according to successive additions without significant modifications of inner city areas. Street networks are represented with linear maps and are analyzed according to measures of connectivit...

In recent years, bike planning has garnered attention from planners and the public as a sustainable mode of transportation and as a means to exercise and reduce health risks. In addition, following the success of bike-share programs in cities in Paris and Lyon, France, and Montreal, Canada, and several US cities initiated similar programs. With this background, GISs have been applied to conduct...
