1 Towards an Integrated Monitoring System for Angkor: Applications of GIS, Remote Sensing and TimeMap for Managing World Heritage Sites PNC 2004 Annual Conference Taipei, October 2004 Damian Evans & Spatial Science Innovation Unit University of Sydney, Australia

2 TimeMap Project University of Sydney, ECAI, Various Developing methods of storing, accessing and displaying scattered cultural resources across the Internet Greater Angkor Project University of Sydney, APSARA, EFEO Archaeological project interested in the settlement context of the monumental remains at Angkor, in Cambodia Living With Heritage Project University of Sydney, UNESCO, EFEO, Various Heritage management project interested in developing management tools and spatial data resources to facilitate research and maganement at the site of Angkor

3 Overview: Southeast Asia

4 Overview: Cambodia s Great Lake

5 Angkor as a Collection of Monuments

6 UNESCO ZEMP ( )

7 Archaeological Zones

8 New Archaeological Sites

9 Greater Angkor Project

10 Archaeological Assemblage

11 Residential Patterning

12 Problems Raised: Tourism Boom Over-development in Siem Reap Town Changing nature of development in Khmer villages Environmental damage

13 One Part of the Solution: Spatial Data Component Interoperability Indexing Incorporation within management plans Making the data available to decision makers

14 Getting the Data into TimeMap Indexing & Creating Metadata XML Editor in ArcGIS to ISO standard Export to TimeMap.tmm format Registration in the ECAI Clearinghouse Data Development Geocoding inventories Georeferencing historical map resources Adding temporal attributes to the datasets Data Sharing & Analysis Development of thematic MapSpaces Making data available over the Internet Developing basic tools for visualisation and analysis

24 Datasets: Remote Sensing

25 Datasets: Remote Sensing

26 Datasets: Remote Sensing

27 Datasets: Derived from Remote Sensing

28 Datasets: Derived from Remote Sensing Wetland classification of Angkor line 20-3 developed from AIRSAR bands Cvv/Lhv/Pvv Tapley & Milne 2003

29 Datasets: Derived from Remote Sensing Rowena Butland 2003

30 Datasets: GPS Acquired Rowena Butland 2003

31 Datasets: GPS Acquired Rowena Butland 2003

32 Datasets: GPS Acquired

33 Datasets: GPS Acquired

34 Datasets: Historic Maps

35 Other Datasets: Artefact Inventory Inscriptions Database Historic Photo Collections Daily Journals of the EFEO Conservators

36 Dealing with Very Large Datasets: Tiled, incremental image servers (ECW, MrSID and Zoomify implemented so far) TimeMap servers deliver only the data that is appropriate to the viewer s current zoom Dataset publishers can specify the appropriate scale at which their data is viewable

37 Problem: Archaeological Uncertainty

50 Other Sources of Temporal Information Inscriptions (dates and text) Structures Ceramics? Existing carbon dates Conservation Inventory Proximity, temporal attributes and spatial autocorrelation

51 Analytical Potential (Archaeological) Relationship over time between residence, religious institutions and water management Intensification of already dispersed landscape? Consolidation of centralised authority? Assessing the validity and applicability of existing chronologies

52 Analytical Potential (Conservation) Rates of land clearance and deforestation Identification of areas of high archaeological value that are under threat from development Identification of areas of minimal archaeological value that are appropriate for development
