| Summary: | The main objective object of this project is to determine the performance of
Global Positioning System (GPS) in road network mapping and to analyze the vehicle
position. The road network near the USM Engineering campus has been chosen as a
study location. Today GPS is a very popular and useful in the field of surveying and
navigation. Many GIS software can be used in GPS measurement technique and it also
can be integrated with GPS data, whereby giving useful information. GIS also can be use
to created a dynamic map where, the map that being create can be filled with any
information or attribute data. GIS map (dynamic) also can be updated and also correction
can be made to the map. ArcView GIS version 3.1 can be used to visualize, explore,
query and analyze data spatially. In this project the Omnilite Reciever 132 and Psion
Workabout Data logger is used to collect the road network data. ArcView GIS version
3.1 is used to analyze the data and also in mapping the road network of the study area.
Coordinate and time data can be obtained from GPS instrument. Vehicle speed can be
computed using this GPS data, so an analysis of vehicle speed on the area can be made.
