VOTER REGISTRATION CENTRES
OBJECTIVES
• To map 1150 voter registration centres• Assign a unique code to a VRC• VRC Database• Spatially linked table data to map elements• List of uniquely coded VRC’s. • Also to investigate methods of maximizing
the capacity of each VRC to hold electronic voter registration (EVR).
DATASETS
• Fiji Topographical Map used as backdrop - SOPAC
• BOS Enumeration Area Map – 2007 Census• 11 yr old population data – 2007 Census• VRC Database – Elections• VRC Field Survey Reports - Elections

INTRODUCTION:
Organizing national events such as a General
Election requires enormous efforts by both the
general public and the office of Elections. Cost
and time effective methods are often needed to
maneuver and ensure the smooth running of the
election process, and with ArcGIS this is possible.
One such method is creating Thiessen Polygons.
These polygons boundaries define the area that
is closest to each point relative to all other points
and are defined by bisecting of the lines between
all points (in this case points will be Voter
Registration Centres- VRC). Creating zones using
the Thiessen (Voronoi) polygon from VRC points
will ensure that each centre is being used to its
capacity (or lack thereof).
OBJECTIVE:
To investigating methods of maximising capacity
of Voter Registration Centres in Fiji using ArcGIS
and Spatial Analysis.METHODS:
From the point shapefile that represented the
VRCs, a Voronoi polygon was created.
The output was then clipped with the coast
shapefile and intersected with the Enumeration
Area for Census 2007. From the attribute table in
the 2007 Census, several fields were created so
calculating the number of people within these
intersected area:
• TotalEA_Area
• Int_Area:
•Int_Pop:
•Prop_Area
RESULTS:
CONCLUSION:
After the completion of this project, the method of creating Thiessen/ Voronoi polygons to determine how to maximize the capacity of voting registration centers by
coupling it with enumeration area data was understood better.

DISCUSSION:
From the map, one was able to determine the number of people
that each voting centre can accommodate, according to the 2007
Census. This would benefit the elections office as it would help
prepare each individual centre according to the number of people
that it can accommodate. However, it should also be noted that the
results shown are susceptible to change considering the changing
population of the nation.
