Abstract

The Global Positioning System (GPS) has transformed topographic mapping and engineering surveys worldwide, offering high-precision, efficient, and scalable solutions for geospatial data collection. In Nigeria, where rapid urbanization and infrastructure development demand accurate surveying, GPS plays a pivotal role. This paper explores the principles, methodologies, and applications of GPS in topographic mapping and engineering surveys, with a focus on a case study from Nigeria: the topographic mapping and engineering survey for the Lagos-Ibadan Expressway expansion. The study highlights GPS’s advantages, challenges such as signal obstructions and limited Continuously Operating Reference Station (CORS) infrastructure, and emerging trends like Real-Time Kinematic (RTK) GPS and drone integration. By analyzing the Nigerian context, this paper underscores GPS’s impact on sustainable development and offers recommendations for improving its adoption in resource-constrained settings.
