Abstract: The rapid expansion of infrastructure demands accurate, efficient, and cost effective site investigation methods. Remote sensing technologies provide a unique advantage by enabling large-scale, multi-temporal data acquisition without extensive ground disturbance. This paper explores how remote sensing can be effectively utilized in site investigation for infrastructure development, including terrain analysis, geological mapping, hydrological assessment, and land use classification. Technologies such as optical imagery, synthetic aperture radar (SAR), LiDAR, and thermal remote sensing are discussed in terms of their suitability for different phases of site selection and feasibility studies. The integration of remote sensing with Geographic Information Systems (GIS) and ground-based surveys enhances decision-making, reduces risks, and ensures sustainable development. Challenges and future directions for incorporating remote sensing in infrastructure planning are also presented.
