A successful project in automated map generalization under-taken at the National Atlas of
Canada made extensive use of the implicit perceptual information present in road and river …

Spatial data generalisation or abstraction is a vital computational procedure in data
presentation (notably in cartography) and in data integration. This paper considers the …

A technique is presented for determining and quantifying the functional importance of road
segments in a road network, according to a set of source/destination [" source and …

Roads are essential component of topographic maps and spatial databases. The challenge
in automated generalisation of road networks is to derive a connected network while …

Strokes are relatively simple linear elements readily perceived in a network. Apart from their
role as graphical elements, strokes reflect lines of flow or movement within the network itself …

A number of researchers have explored ways of automating the reduction in level of detail of
road networks as part of the automated map generalisation process. The broad context of …

A road network is cartographically drawn in varying levels of detail depending on the
resolution or scale of the output graphic. In automated generalization, the challenge is in …

When a human cartographer designs a map, the symbols represent objects in a way that
attempts to convey geographic process occurring at a given scale. The skill is in abstracting …

Publisher Summary The chapter introduces the subject of pattern recognition in road
networks. It describes the concepts of random and scale-free graphs, since scale-free …
