Does the “analysis of shape characteristics” reveal line structure ?
This study was prompted by the idea that one process within bendsimplification, namely iterative bend elimination (Wang, 1995), appeared to be useful for revealing line structure. However, the paper by Wang and Muller (1998) was not unequivocal about the value of bendsimplification in structure analysis. Hence, one objective of the study was to resolve possible misinterpretations in the reading of their text. They initially note that “Bends are hidden behind the x-y coordinates of the line feature and reflect a line structure which must be computationally revealed. Therefore, the major task is to write a program capable of understanding the structure of spatial information… i.e. detecting bends and computing their attributes on which generalization decisions can be made. ” (p 4, our emphasis) and that “Most existing line generalization solutions are based on geometric processing without previous shape analysis … ” (p 5). Although bendsimplification is still in the realms of geometr
