Abstract
Digesting the data hose that cities are constantly producing is complex; data is usually structured with different criteria, which makes comparative analysis of multiple cities challenging. However, the publicly available data from the Spanish cadaster contains urban information in a documented format with common semantics for the whole territory, which makes these analyses possible. This paper uses the information about the 3D geometry of buildings, their use and their year of construction, stored in cadastral databases, to study the relation between the built environment (what the city is) and the urban plan (what the city wants to become), translating the concepts of the cadastral data into the semantics of the urban plan. Different representation techniques to better understand the city from the pedestrians’ point of view and to communicate this information more effectively are also discussed.

Urban morphology is constantly evolving: buildings are built, demolished, and remodeled altering the landscape of our cities through the collective action of their inhabitants
The objective of this study was to assess the information stored in the cadaster databases, especially in relation to the urban planning regulations, and the interpretation of the data stored in these two sources with different semantics, to be able to relate them spatially and conceptually
Understanding the interactions of pedestrians when walking along a street is crucial for urban planners because it has a direct impact on their perception of the city
Summary
Urban morphology is constantly evolving: buildings are built, demolished, and remodeled altering the landscape of our cities through the collective action of their inhabitants. The analysis of the complex interaction throughout time between what the city is and what it wants to become [1,2,3] allows urban planners to understand both past and present state of the city to plan for a better future. The purpose of this paper is to present a methodology to provide urban planners with analytic visualization tools to better understand the complexity of urban renewal processes [7], using publicly available cadastral data. This approach makes possible to use the methodology in multiple Spanish regions since cadastral data covers the whole Spanish territory with a uniform semantic criteria
