Mapping Angkor: Applying TimeMap Principles to Building a Distributed Geographic Database

A team from the University of Sydney working in collaboration with APSARA (the Angkor management authority) and the Ecole Francaise d’Extreme Orient has been carrying out archaeological survey work at Angkor since 1999, along with targeted excavations and sediment coring. The project is known as the “Greater Angkor Project” (GAP) and is currently funded through 2009. Baseline GIS data created for a UNESCO-sponsored management plan in 1992 (ZEMP – Zoning and Environmental Management Plan) has been augmented through the analysis of aerial photography and AirSAR radar images by Christophe Pottier (EFEO) and Damian Evans (University of Sydney) to build a comprehensive picture of Angkor as a low density city extending over more than 1000 square kilometres.

In January 2005 we carried out pilot fieldwork for a new five year project entitled “Living with Heritage”, which builds on the existing GIS infrastructure to develop methods of monitoring the impact of development on the heritage landscape. This project will also map contemporary experience and perceptions, including the views of administrators, tourists and residents. We are matching remote sensing evidence with on-the-ground observation to identify development indicators which can be recorded with simple technology appropriate to heritage landscapes in developing countries. We are also developing ways of integrating community views and other qualitative data into a heritage management GIS, with a view to building a comprehensive information system for geographic, archaeological and heritage management data. The project is a broad collaboration with the main partners being APSARA, EFEO and the UNESCO World Heritage Center. The methodologies developed are intended to be widely applicable to extensive heritage sites with large contemporary populations.

In this paper I will first summarise the existing work of the Greater Angkor Project and the understanding developed of Angkor as a massive archaeological landscape extending far beyond the prominent monuments. I will then outline the IT infrastructure we are developing as part of the Australian Partnership for Sustainable Repositories, which will allow us to integrate a broad variety of spatial datasets in individual custodianship and deliver information through our TimeMap™ web mapping software. Finally I will offer some comments on the difficulties we face in implementing such a system across a wide range of agencies and levels of technological infrastructure.

The aim of this paper is give a visual and oral dimension to displaying the urban growth of Guadalajara over the last 600 years. In order to enrich the static maps on urban growth that we have been working on for the last four years, we shall generate a time map with historical and contemporary information. This includes: population data, images (photos, engravings, paintings, digital elevation models, orthophotos, aerial and satellite images), modern readings of chronicles of the past and sound recordings of recent interviews, records of environmental changes showing, in particular, the transformation of the use of land and of its resources. At this stage we will concentrate on gathering and organizing the necessary information, and take the first steps in building up a time map, which will take three years. The period from the 16th to the 19th century will be organized by centuries and there will be a zoom-in, by decades, for the 20th century. The main structure of the time map consists of: the colonial period, the 19th century and the 20th century. As the project only began in March, we shall concentrate, for this presentation, on an example from the colonial period.

The new project of constructing the full-text database of historical earthquake documents in the ancient and medieval ages in Japan has started. This project is aimed to reorganize and digitize all historical documents on earthquake activities and disasters before 17th century of Japanese archipelago, and is intended to compose a seismic intensity database. This paper will describe the digitization and database system parts of the project and its application to “TimeMap.”
