|Abstract: ||Searching information on maps is known as a tedious and time consuming
process. Nowadays, there are many electronic maps which can facilitate
searching. However, these maps cannot provide specific information around a
place. That leads a user manually search his desirable information. This
behavior should not be as small as possible.
In this project, it aims to develop Range Query Processing System in order to
provide services for a user to search specific information fast and easily.
Range Query Processing System can provide a service to create, build, load a
map and query a point or an area of the map. Like other Geographical
Information System (GIS), it also provides zooming effect to help the user find
information easily in a large map. Unlike other GIS, it provides two features to
the user who is interested in the structure of the map. On the other hand, to
enhance the system usability, it provides a good User Interface to help the user
operate the system easily and conveniently.
At the end, the performance of Rang Query Processing System is evaluated
with different criteria. The testing data is a road of California. It is found that the
system can deal with a large query dataset within a few seconds.|
