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research papers, historical documents ↓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?
Introduction (2) ProposalSupport more efficient research.
1. Data Integration (maps , historical materials , and GPS data)
2. Enable reuse of data, exchange data efficiently
↓ Development of an information sharing
system based on a GIS tool and a Clearinghouse
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.
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historical documents, research papers, web pages, digital archives…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…
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
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
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

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
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
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

Summary Proposed Geographical Information Sharing System
System properties Integrate geographical information (maps, satellite i
mages), non-geographical information (documents), and moving object information (GPS data)
Enable the reuse and sharing of information Seamless GI, NGI and MOI browsing environment
Future Tasks
Implement and evaluate a GISS prototype system.
Detailed examination of the GISS spatial analysis framework
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

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 to1. Share real time MOI and annotations with other
researchers2. Integrate GI and MOI data
