Spatial Analysis of Topographical Map Sheet 266 Auchi S.E For Socio-Economic Development

The research is on the spatial analysis of the topographical map sheet 266 Auchi S.E with a focus on its implications for socio-economic development. The existing map last updated several decades ago, no longer accurately represents the current terrain and land use patterns in the area. The high and accelerating rate of change and expansion of urban centres demands a fast technique for updating existing maps. The research demonstrates the application of satellite imagery and the Shuttle Radar Topography Mission (S.R.T.M) in topographical map revision. The S.R.T.M. and Google Earth imagery of 2024 of the study area were used to update the existing topographical map of the study area. AutoCAD Land-dev 2009 was used for geo-referencing and digitizing of the required features while ArcGIS 10.1 was used in processing and analyzing the data. Global Positioning Systems (GPS) and Geographic Information Systems (GIS) techniques were utilized in updating the topographical map to reflect recent changes in the landscape. The revised map reveals significant alterations in land use, infrastructure development, and demographic patterns. The study analyses the socioeconomic implications of these changes, highlighting opportunities for sustainable development, infrastructure planning, and environmental management. The revised map serves as a vital tool for policymakers, urban planners, and stakeholders, enabling informed decision-making and contributing to the socio-economic growth of the region. It is recommended that revisions of all categories of maps should be embarked upon, and for fast revision and production of maps, the use of remotely sensed data should be adopted by relevant mapping agencies.
