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...

This paper presents a new approach to line generalisation which uses the concept of ‘effective area’ for progressive simplification of a line by point elimination. Two coastlines are used to compare the performance of this, with that of the widely us... Read More about Line generalisation by repeated elimination of points.
