GIS technology has emerged as a powerful set of tools for managing and analysing spatial data (data tied to a specific point or area on the ground). The various types of spatial data are at the core of many development efforts, and GIS is seen as a solution to a number ofproblems local governments face in their area of jurisdiction.

This handbook serves as an introductory guide to geographic information system (GIS) technology for local government and other interested stakeholders. It suggests some common opportunities for GIS application, the benefits a GIS provides to users, and what is required to set up a GIS and sustain it.

This manual provides detailed, step-by-step instructions for administrators and technical personnel on how to set up and operate a Geographical Information System in a municipal context using ArcGIS software.

Different GIS products may be used, though the procedures may change as a result. Rather than replacing existing policies and guidelines, the manual provides clear instructions on operationalizing GIS development.

Professor Yeh explores the use of Geographic Information Systems (GIS) as a Planning Support System for urban planning. Despite the growing popularity of participatory approaches in favour of computer generated planning models, he argues that GIS remains vital for facilitating informed discussion and decision making in urban planning.

As a computerized system for the storage, retrieval, visualization, analysis and modeling of spatial information, GIS greatly facilitates different stages of the urban planning process. The growing user friendliness, affordability and performance of GIS in recent times, he notes, has further enhanced its utility as an effective planning support system. He maintains that provided constraints in the use of GIS such as data availability and skill limitations can be overcome, GIS can provide excellent support for the planning of harmonious cities.
