This project was aimed at producing a digital topographical plan of the Methodist High School, Owo in Ondo State. The first chapter of the project covers the introductory aspects. Literature review was discussed in chapter two, and chapter three talked about the methodology. Hence, reconnaissance surveys both field and office were carried out in order to be familiar with the nature of the terrain and the requisition and assembling together of viable information from both primary and secondary sources of data respectively. The spatial data were acquired through the use of total station. The processes of traversing, leveling, spot heighting and detailing were simultaneous carried out with the use of the digital equipment (i.e total station), in the determination of the spatial coordinates (Northings, Eastings and Heights) of the boundary stations proposed for future developments (spot heighting). In the database design, creation and management stage, Arcview GIS 3.2A was used to design the spatial database. Spatial analysis and presentation were discussed in chapter four. The topographical plan of the area of study was produced in soft copy at a scale of 1,5000. The interpretation of this plan support decision making policy needed by Environmental-oriented professionals (such as Estate Surveyors, Engineers, urban and regional planners, Architects and even land surveyors) to plan, design and execute vital infrastructural projects. Conclusively, chapter five contained the summary, conclusions and recommendations.
