Describing the functional spatial structure of urban environments

People learn the layout of cities mainly through a series of trips. Wayfinders experience the city structure differently depending on the mode of transport they use. The acquired mental representation then consists of the directly observed, physically accessible parts of the city. In this paper, we propose a computational model to construct images of cities, adapting their content depending on the wayfinder’s access constraints. First, we formally study and extend the classification of Lynch’s elements of the city form. Second, we propose a simple approach to analyzing local functional relationships between these elements, as experienced by wayfinders. The study of the functional relationships allows for the construction of the most complete image of the city that might be acquired by a wayfinder with given accessibility characteristics. These representations of urban environments can support advanced spatial assistance systems and cognitively efficient spatial interfaces.

Recognition of two-dimensional representation of urban environment for autonomous flying agents

In this paper the problem of a vision system implementation for autonomous flying agents is considered in the context of industrial inspection tasks performed by unmanned aerial vehicles. A syntactic algorithm of a two-dimensional object vectorization and recognition is proposed. An algorithm of two-dimensional map recognition has been introduced as well. The algorithms have been tested by using both artificial data and real data - the satellite image. They have turned out to be effective.

Picturing the city: young people's representations of urban environments

Urban environments form the setting of everyday life for most Western young people. This article explores visual representations of cities made by young people in a range of environments within four countries. The findings inform a larger study on urban geographies within geography education. We analyse students' drawings of cities regarding physical characteristics, activities and issues. There are many commonalities between drawings from the four countries, the majority showing a ‘big, busy city’ representation with skylines, traffic and shopping areas. There are also distinctive characteristics for each set, for example Finnish students tended to emphasise environmental and social issues more than in the other countries. In relation to methodology, we conclude that drawings, supported by contextual information, are a useful source to understand young people's representations of cities. Further, this research supports thinking about how to merge young people's experiences and imaginaries with the teaching of urban geography.
