Topographical Information Systems: A Tool for Sustainable Development and Effective Decision-Making

The project titled Topographical Information System (TIS) for Alaafin High School, Agunpopo, Atiba Local Government Area, Oyo State" aims to develop a comprehensive digital system to manage and utilize topographic data for decision-making and infrastructure planning. The project involves the use of modern surveying techniques and equipment, such as Differential GPS, to gather spatial and non-spatial data. The objectives include data acquisition, processing, database design, and presentation of composite maps for the study area. The methodology focuses on field reconnaissance, data collection using geometric measurements, and subsequent processing through GIS software (ArcGIS 10.2). The data is stored and managed in a spatial database, which facilitates queries and analyses for effective decision-making related to utilities management, infrastructure development, and environmental monitoring. The project also identifies challenges in the existing analogue systems, such as difficulty in updating maps and retrieving information, and proposes a digital approach to address these issues. The TIS generated in this project has various applications, including 3D map displays, slope and aspect analysis, and volume estimation, all of which are valuable for urban planning, environmental management, and infrastructure development. The project contributes for better planning and management of resources in the study area.
