User-centered design of a collaborative, object oriented historical GI-platform

Abstract

The project STREAM (Spatio-Temporal Research Infrastructure for Early Modern Flanders and Brabant) aims to create a research infrastructure that will allow spatio-temporal analyses in order to improve our understanding of the demographic, social and economic changes that occurred in Flanders and Brabant (Belgium) between 1550 and 1800. The Carte de Cabinet of count Joseph de Ferraris (1771–1778) offers information on various subjects for that time period and is considered one of the most important products of Belgian cartographic history. Hence this historical map was used as the main source document to develop a vectorial geographical database that constitutes an important step towards the creation of a research infrastructure. To build this geographical database a retrogressive method was used in order to interpret the historical map and its related data in an absolute geographical reference system, which the Carte de Cabinet lacks. Since STREAM results from a collaboration between researchers from different disciplines a specific user-oriented editing platform was developed to support the different actors. This platform allows the digitisation of the historical road network in a geographic reference system based on the current road network by means of a slider, a shift tool and an editing tool. Initial analyses have confirmed the strong geometric distortions of the Carte de Cabinet but also the multiple possibilities for spatio(-temporal) research when combining the information of the Carte de Cabinet with cartographic analyses of other cartographic documents.
