time and memory space while still able to provide reasonably good 3D visuali-
zation representation. Additional drawback of the pilot system is the 3D texture
and facade of the 3D surface model was not completely uploaded to the system
viewer. Thus, simplifying of the 3D model is recommended and as a result 3D
panoramic VR was employed in the revised system. Buffer and radius functions of
the pilot system have been a sole geo-processing query that employed the most
simplified rules of buffer and radius search. As accessibility and mobility of
potential property to the nearest facilities or POI influenced the selling transaction,
the improved buffer query was integrated with specific topological rules and
geometric network data. These improvements allow users to query buffer and
radius of selected property not by simply looking at the spatial location but also the
route accessibility and connectivity. As such, the query result can also provide
distance and road connectivity information. The new schematic function for geo-
processing and geometric network query demands for shifting the independent
system to ArcGIS Server with Adobe Flex viewer to enhance the GUI. These
modifications have improved the traditional radius and buffer results and will
potentially improve the 3D visualization functions.
