Spatial Temporal Relational Graphs on Connected Landscapes


Alan Kwok Lun Cheung, David O'Sullivan and Gary Brierley

Abstract: The structure of computational spatial analysis has mostly built on data lattices inherited from cartography, where visualization of information takes priority over analysis. In these framings, spatial relationships cannot easily be encoded into traditional data lattices. This hinders spatial analysis that emphasizes how interactions among spatial entities reflect mutual inter-relationships at a very basic level. With this limitation, landscape compositions and configurations can be appreciated further if a topologically and temporally enabled data structure is available. The aim of this research is to develop a data structure and its associated analytical methods to assess the connections and interactions of landscape elements through time and space. This additional layer of information will help us understand the dynamics of processes happening within and between components of landscapes.

From Medieval Data to Geo-resources on the Web - An Innovative Way of Mapping History


Guido Minini

Abstract: The research project presented in the paper is being carried on in the Geodesy and Geomatics area of a Ph.D program in Environmental and Infrastructure Engineering. It raises from a Research Project of National Interest funded by the Italian Ministry of University and has the aim to equip Historians with a tool that can facilitate their work in terms of consulting historical archives. This project has been dealt with by using a cognitive approach, in order to identify the key issues and the appropriate tools to help the Historians in satisfying their research needs. Data collected from historical Medieval sources in Italian National Archives have been initially organized into a spreadsheet; the data have been associated with spatial information (point coordinates), corresponding to the place names found in historical sources: knowing the spatial reference it was then possible to import data into a Geographic Information System (GIS). The main focus of the Ph.D. program activities is the publication of the Medieval data in the Web, in order to make them available for the consultation and query by Historians. Two kinds of approaches have been explored: one is typical of the WebGIS architecture, while the other is again based on a client-server architecture, but in this case only the data, collected into and managed by a Database Management System (DBMS), are stored in a server and the GIS tools are provided by a Desktop GIS installed locally on a PC. In the paper, the two architectures will be described, comparing them in order to underline advantages and disadvantages of each approach.
