Figure 1 : Study Area 
Attributes are held in a dBASE format file. Each attribute 
record has a one-to-one relationship with the associated shape 
record. Attribute information of the features such as name of the 
quarter, name of the street, number of the door, functionality of 
the building, basement, medium floor, roof, total floor, 
condition of the building, registration, name of the building, 
construction date, financer, style of the building etc. were stored 
in the database table. In the index file, each record contains the 
offset of the corresponding main file record from the beginning 
of the main file. 
An example for a shape file naming convention 
• Main file: binalar.shp 
• Index file: binalar.shx 
• Database table: binalar.dbf 
Figure 2: Data Structure 
2.1 Heritage Information System on the Internet 
Geographic Information can be distributed in any form over the 
Internet such as static map images, simple map services, or 
advanced GIS. In this study, mapping application type is 
dynamic web browser which means that the Internet sends map 
parameters, and the map image is formed according to the 
setting parameters. In Figure 3, the architecture of the dynamic 
map browser is shown. 
The graphical and geometrical data generated from digital maps 
and other graphical external files (like digitized plans, amateur 
photographs etc.) and the alphanumeric data related to the 
graphical data were linked and managed together by the GIS 
software Arc View 3.2 for creating a geographic information 
system. In this study, Arc/Info GIS software has been used for 
the establishment of topology of the coverage, which is the 
basic unit of storage. Then the coverage has been imported to 
Arc View software for several query and analysis advantages. 
Digital data in dgn format have 25 different layers. These digital 
data were transferred into AutoCAD file format and the number 
of these layers reduced in AutoCAD. Figure 2 shows the main 
layers.

Figure 3: Architecture of Dynamic Map Browser 
The tools used in the study for creating such an architecture are 
Map Objects ActiveX software component and Map Objects 
Internet Map Server (MOIMS) software. Map Objects builds 
GIS application and MOIMS is a gateway program between 
Web Server and the mapping application. In the study, these 
tools were embedded into a Visual Basic file. All map layers 
and functions on the web page were added by writing codes in 
the Visual Basic. Microsoft Personal Web Server program was 
used for information sharing over the Internet. 
Map Objects ActiveX software component has the following 
functions: 
• Display a map with multiple map layers, such as 
roads, streams and boundaries. 
• Pan and zoom throughout a map. 
• Draw graphic features such as points, lines, ellipses, 
rectangles and polygons. 
• Draw descriptive text. 
• Identify features on a map by pointing at them. 
• Select features along lines and inside boxes, areas, 
polygons, and circles. 
• Select features within a specified distance of other 
features and more... 
Data layers, data types, feature types, and file formats for 
serving over the Internet are shown in Table 1. Figure 4 
displays the web page.
