Abstract

Much of the success of location-based applications comes from using spatial
analysis in query processing and graphic visualisation. Recently, with the arrival
of miniature and inexpensive GPS receivers and cellular phones, new horizons
have been opened for these applications. The mobile telephone and Internet
technology within the GIS environment has fostered new applications with
higher degrees of user satisfaction. The advance this technology affords for data
acquisition, facilitates the provision of real-time location-based services.
Recently, considerable work has been undertaken in feasibility assessments and
in identifying the type of services and applications that can be offered to mobile
persons in an environment equipped with mobile telephones, Internet technology
and GIS. No equivalent attention has been given, however, to the data that will be
used for running such services. The acquired data have some degree of uncertainty
mainly due to system error associated with acquisition devices and limitations in
representing continuous data temporally.
By focusing on restricted movement on a road network, this paper proposes a
spatial registration technique to reduce the error associated with location data; it
also proposes consistency checks and time registration in an effort to compensate
for times when no observation is available. The processed data will also reduce
the ambiguity in determining the current location of an object within the network.
