2.3 Integration with Web-based GIS
In the study, Map Objects ActiveX software component and
- Map Objects Internet Map Server software (ESRI) were used.
y Map Objects was used to build the GIS application and MOIMS
was used as a gateway program. Map Objects and MOIMS
were used together with Visual Basic, which is an application
development environment. Microsoft Internet Information
Services Program was used to share information over the
Internet. Figure 7 and figure 8 shows samples of internet
application from browser.

3. CONCLUSIONS
Points taken photos in, also were measured by handheld GPS
because of determining coordinates of panoramic images. After
measurement with handheld GPS, we obtained WGS-84 datum
geographical coordinates. The coordinates should have
projected to 3 degree Gauss-Kruger Cartesian coordinates.
Table 1 and Table 2 illustrate coordinates and projection result
for GPS measurement.
Web-based GIS applications combine the advantages of both
GIS and the Internet. Linking spatial data with panoramic
images and other non-spatial data has a potential for
environmental management, urban planning, preservation, and
tourism. There will be subsequent improvements in the
functions and capability of the application to make it more
efficient.
