ABSTRACT
This paper made attempts to unravel the unique processes in using an interactive system known as Geographic Information System (GIS) to model demographic details of an area in Nigeria. In order to achieve the main objective of the paper, an interactive computer-based system that can support effective management of demographic data management was developed. In the process, attribute data modeling and linkage of the attribute data with the spatial information was performed. The main package for the study was the ArcGIS 9, which was complimented with AutoCAD among other softwares. They were useful for the dataset querying and analysis. Demographic datasets thus provided an important input to GIS. The study was restricted to GIS and its implication in database building and management for spatial and non-spatial dataset required for overlay and query analysis. Therefore, complex statistical details and other demographic variables that accompany census related activities were not on focus. Recommendations were suggested after the exercise.
Keywords: Interactive, Demographic dataset, Contemporary practice, modeling.
