This paper demonstrates how to explore a design of a multimedia supported four dimensional (4D) information system to aid 
geographically-oriented the documentation of the two Ottoman fortresses of “Seddülbahir” and “Kumkale” through internet. This

perspectives for historical documentation projects. Additionally,

"GeoHistory" has been implementing in order to build an open, seamless development environment. This paper will describe the 
design of "GeoHistory" as a SIS model and integration with its sub-components, such as “GeoHistoryRepository”, 
“GeoHistoryQueryInterface”, “GeoHistory VirtualInterface" and provide an efficient method of documenting historical structures. 
I. INTRODUCTION 
The cultural heritage is the most important evidences regarding 
the past society and each object of these has valuable 
information about the past. Unfortunately each valuable element 
of the historical structures has been vanishing day by day 
through time, nature, and human effects. Hence, some 
precautions are needed for protecting these historical structures 
from the corrosion and human effects. There are also two 
Ottoman Fortresses, called “Seddülbahir” and “Kumkale” on 
Dardanelles, Turkey in the same situation, however, the project 
team working with these monuments believes that the fortresses 
can be restored and protected only when it has been fully 
measured, documented and stored in proper historical 
information and management systems. They were both built in 
the mid seventeenth century (1656-1659) at the entrance to the 
Aegean, on either side of the Straits by Turhan Sultan, the 
mother of the Ottoman Sultan, Mehmet IV. (Guney et al., 2002) 
The Documentation Project of the Ottoman Fortresses, 
"Seddülbahir" and *Kumkale", is a joint project undertaken at 
the Division of Geodesy, Istanbul Technical University (ITU) 
and the Department of History, Koc University; to explore a 
preparation of a multimedia supported four dimensional (4D) 
information system through internet to aid geographically- 
oriented the historical documentation of the fortresses. It is with 
this larger, long-term goal that the team of surveyors, architects, 
historians and archaeologists began in 1997 to working together 
on the project. The location of the fortresses is approximately 
26°.199 Errrr and 419.006 Nîrrr and the distance between the 
two fortresses is approximately 4150 meters. As ""Seddiülbahir" 
is located on the European side of the straits, at the southern end 
of the Gallipoli Peninsula. The fortress of “Kumkale” is on the 
Opposite Asian shore, approximately five kilometers from Troy. 
Fast developing technology in the area of geo-informatics 
makes the use of "Spatial Information Systems (SIS)" exciting 
10 utilize and an opportunity to challenge much better decision 
making for many fields like history, archaeology etc. SIS can be 
used to analyze any issue with a spatial component in these 
fields. 
This paper demonstrates how a SIS project can be designed and 
managed for historical researches. This paper examines a 
variety of ways in which SIS application for a historical 
documentation project can be integrated with technological 
developments within the fields of database, visualization and 
internet. 
2. SIS PROJECT OVERVIEW 
The design and management of SIS-based historical 
documentation project of the two Ottoman Fortresses, 
"Seddülbahir" and “Kumkale”, is considered as a multi-purpose 
and multi-participants information technology (IT) project since 
each discipline in the project contributes to the study with its 
science domain and expects different outputs rather than other 
science domains, and the project has various purposes for the 
different level users such as decision makers, users, end-users. 
After project team understood the context of the project, 
formulated the questions concerning the project with rich 
pictures and root definition and determined the expectations 
from the project the vision and mission of the project was 
created, and the strategic plan of the project was produced due 
to the requirements and the phase of analyzing. Flow chart of 
the stages and timings were constituted upon the strategic plan 
or SIS development process. 
The vision of the project is to model accurately the “life history 
of the fortresses” within a SIS project to determine more 
accurately and efficiently the architectural changes from 17" 
century to the present day and to explore the natural, 
economical, social and political events, which have caused 
structural changes to the fortresses and surrounding buildings 
and environs. (Guney and Celik, 2004a)
