Spatial Evolution of Building Types: Methodological proposals

Résumé

This paper presents different methods implemented with the aim of studying urban perforation and regeneration dynamics at the building level. The minimum requirement to perform these methods is a building footprint available for two different periods (time depth of at least 10 years) and heights (or floors) as attribute data. First, basic morphometric indicators are computed for each building: area, floor-area, number of neighbors, elongation, and convexity. Based on the availability of expert knowledge, different types of classifications and clustering are performed to obtain building types. A grid is superimposed on the test region of Osaka (Japan) and the number of building types per cell and for each period is computed, as well as the differences between each period. Mappings are then performed, showing that building types have specific locations and evolution trajectories. In some extreme cases, a specific building type can even gradually replace a type on a declining dynamic.
