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.
