Abstract:
The development of a web-based Geographic Information System for mass
property valuation was the main focus of this research. The developed web
GIS allows effective dissemination, extraction and analysis of mass land valuation
information over the Internet. It also allows for automation of the mass
property valuation process by compiling a centralized mass valuation roll database.
The Westlands Constituency, one of the administrative regions of the
Nairobi City County was used as a case study. The research focused on automation
of the mass property valuation roll by creating a centralized database
that is accessible by all users on the web-based GIS portal. This was done by
customizing and integrating a web-based GIS system based on open source
QuantumGIS, GeoServer and PostgreSQL/PostGIS as a relational database.
Leaflets APIs were used for the development of an interactive and friendly
geographic user interface. The developed system enables users to view and interact
with the spatial data. This improves the efficiency and effectiveness of
the decision making process and data sharing for mass property valuation and
optimal property taxation purposes.
