There are two interfaces for the analysis of spatial patterns. This deals with summary details over pre-defined areas. In the case of the Ascoli project, these areas are combinations of the contrade and streets mentioned in the State of Souls registers, grouped according to associations found in the notarial documents and oral tradition. A generalised version of this interface has also been developed which can import any simple bitmap and can be attached to any Microsoft Access database. The second spatial pattern interface superimposes circles representing individual buildings onto an early twentieth century cadastral map of Ascoli.
Queries result in colour changes.
In addition, clicking on a house generates a query to the database that returns a list of the people resident in the house. Further functionality has been added to this interface by incorporating animation to represent change over time. One example retraces the route of the compiler of the 1731 State of Souls register. Another shows the development of the built up area of the town. Both of these interfaces are based on the same techniques.
