Venice Families and Real Estate

Introduction

The Catastici and the Cadaster hold information about who owned buildings in Venice in the years 1741 and 1808. In order to find out how power shifted between families in this time, we will look at the change in real estate between these years.

Plan and Milestones

First Steps

The first step working on the project was to familiarize ourselves with the datasets. We started working on the cadaster, as we assumed it would be easier to handle. After extracting some general information about the owners of the parcels, quickly we had to realize that the parcel owner column of the dataset is not homogenous in the way it is constructed. This is due to the way the data was extracted, and as it is based on scans of hand written documents, we found we had to deal with all kinds of problems associated with handwritten documents.

The Sudetto problem

The sudetto problem appeared quite early when working with the cadaster from 1808. Whenever multiple consecutive parcels have the same owner, most of the later entries have no owner specified anymore but the value of the column is 'sudetto'. Sometimes the later entries still contain the actual name of the parcel owner, in addition to 'sudetto'.
