  1. Development of Japanese GIS Tool for use in the Humanities ○Masatoshi ISHIKAWA†, Yoichi KAWANISHI†† , Hidefumi OKUMURA†††, Shoichiro HARA†††† †University of Shimane , †† Kyoto University, ††† Human ook, †††† National Institute for the Humanities PNC 2005 Annual Conference, Nov. 2 2005

  2. Presentation Points • Introduction • Definitions • Functions of Geographical Information Sharing Systems • Geographical Information Sharing Model • System Architecture • View Model of Spatio-Temporal Information • Summary & Future Tasks

  3. Introduction (1) • Using GIS widely in Humanities research • Digitizing historical maps, satellite images, research papers, historical documents ↓ • Humanities research (History, Archeology) • maps，satellite images → GIS, Clearinghouse • historical material, research papers → Digital Library, Digital Archives • positioning data (GPS) → special viewer (e.g. car navigation system) → Is the research environment adequate?

  4. Introduction (2) • Proposal Support more efficient research. • Data Integration (maps，historical materials，and GPS data) • Enable reuse of data, exchange data efficiently ↓ • Development of an information sharing system based on a GIS tool and a Clearinghouse

  5. Introduction (3) • Benefits • Researchers will be able to find information more easily. • There will be more exchanging of opinions and publishing of research results on the Internet.

  6. Definitions • Geographical Information (GI) • digital maps, historical maps, satellite images… • Non-geographical Information (NGI) • historical documents, research papers, web pages, digital archives… • Moving Object Information (MOI) • photographs, annotations including data from GPS devices…

  7. Functions of the GISS(1) (1) Integrate geographical and non-geographical information by a linking mechanism that maps time and place terms in documents onto points on a map (2) Receive location data from GPS devices and display it on a map (3) Retrieve information from clearinghouses by a combination of time intervals, areas and keywords

  8. Functions of GISS(2) (4) Annotate maps and share these annotations with other users (5) Edit geographical information such as creating a new layer, deleting an unnecessary layer, etc. （6） Save the results as a project

  9. Geographical Information Sharing Model • Geographical Information Sharing System (GISS) is a Client/Server type system • GISS server (users enter metadata onto server) • Geographical info → input directly by creator. • NGI → conversion of addresses (place names) to positions including metadata automatically • MOI → margin position data and data which was input previously. • Client (users browse GI, NGI, MOI. ) • WWW application → browsing data，editing annotations • Standalone application → browsing data，editing annotations, editing layers (GI)，serving project and publishing projects via the GISS server

  10. Geographical Information creator client (Standalone application) Client ( Web application) GIS Server (Clearinghouse, gazetteer and so on ) Mobil device (GPS) Request data, editing annotation Submit GI by creator Browsing GI, NGI, MOI Project file Submit NGI Get GI files, etc Internet (WWW) Saving a project Submit MOI Submit project layers (GI) Add layer

  11. GISS system architecutre(1) • GISS server • Clearinghouse • Managing metadata • Processing user queries • Place name dictionary, period dictionary • For converting place names (e.g. Izumo) and period names (e.g. Edo), including documents containing positioning data

  12. GISS system architecture(2) • File server • Managing files (GI files, NGI files or MOI files) • Profile database • Managing user profiles for user certification • Information about MOI registered in advance • Metadata registration support system • Certify users • Validate metadata • Convert place names to positional data

  13. GISS system archtecture(3) • Client • GISS viewer (Web application) • IR, browsing GI, NGI and MOI • Editing annotations • Enable changing of layer properties. • GISS viewer (Standalone application) • IR, browsing GI, NGI and MOI • Editing annotations • Editing layers • Project saving and publishing via the GISS server

  14. Browsing model for GI, NGI, MOI • GISS Function • Map operation • Zoom in/out, pan • Layer operations (display/hide layers) • Time operation • Time slide bar • Animation creation ↓ A user can seamlessly browse GI, NGI and MOI data.

  15. World map scale Automatic map change by zoom in and zoom out layer1 (hyperlink) Hyperlink to web page, photographs and so on layer2 (map) Area map ・・・ ・・・ layer1 （hyperlink） Map A (historical maps) Map B (present time) layer2 (map) ・・・ ・・・ ・・・ Automatic map change by period changes time

  16. Summary • Proposed Geographical Information Sharing System • System properties • Integrate geographical information (maps, satellite images), non-geographical information (documents), and moving object information (GPS data) • Enable the reuse and sharing of information • Seamless GI, NGI and MOI browsing environment

  17. Future Tasks • Implement and evaluate a GISS prototype system. • Detailed examination of the GISS spatial analysis framework

  18. Example 1 Example for GI and NGI integration • Ancient tomb distribution map (map: GI) • Mokkan DB (text data: NGI) → Integration of data was considered difficult because it had to be done by hand. ↓ • Efficient data integration using metadata on the GISS

  19. Mokkan DB Data entry Ancient tomb distribution map (GI) Mokkan data (NGI) GISS server Searching and obtaining results Mokkan photo Integrating GI and NGI

  20. Example 2 • Field work collaboration using the GISS • Information from research groups • Data entered in real time to the GISS server (MOI) • Information on the Internet • GI such as satellite images，historical maps (GI) Furthermore researchers are able to • Share real time MOI and annotations with other researchers • Integrate GI and MOI data

  21. Via the Internet A map with a hyperlink to results of the research Browsing data Editing annotations Input field data Browsing data, Editing annotations Research Group A Research Group B （Real world）
