A cognitive approach to road recognition with novel feature indicators (1996)
Journal Article
Varley, D., Visvalingam, M., & Wright, C. (1996). A cognitive approach to road recognition with novel feature indicators. Computer Journal, 39(9), 751-756. https://doi.org/10.1093/comjnl/39.9.751

This paper outlines a simple strategy for recognition of prototypical cases of urban roads from their outline forms alone. Two new form indicators, namely exits and occupancy, are used together with average width to label regions as roads. They prove...

Road extraction and topographic data validation using area topology (1994)
Journal Article
Varley, D. A., & Visvalingam, M. (1994). Road extraction and topographic data validation using area topology. Computer Journal, 37(1), 3-15. https://doi.org/10.1093/comjnl/37.1.3

A simpler novel process for extracting roads is outlined in this paper. The procedures which were adopted for checking the consistency of semantic labelling is described. And it discusses the extent to which findings should influence the database mod... Read More about Road extraction and topographic data validation using area topology.

Global dimensions for the recognition of prototypical urban roads in large-scale vector topographic maps (1993)
Preprint / Working Paper
Visvalingam, M., Varley, D., & Wright, C. P. Global dimensions for the recognition of prototypical urban roads in large-scale vector topographic maps

This paper outlines a simple strategy for recognising prototypical cases of urban roads given only their geometric forms. Two new indicators, namely exits and occupancy, are used together with average width to label regions as roads. Even in its pres...

Area topology for road extraction and topographic data validation (1993)
Preprint / Working Paper
Varley, D., & Visvalingam, M. Area topology for road extraction and topographic data validation

First paragraph:
The Cartographic Information Systems Research Group (CISRG) of the University of Hull is researching the automatic recognition of spatial objects based on their spatial descriptions alone. The feasibility study , reported in this pa... Read More about Area topology for road extraction and topographic data validation.
