GIS

Definition

Geographic Information System (GIS) is a technology that enables the collection, analysis, and visualization of geographic data. It integrates hardware, software, and data to capture spatial information and allows users to understand relationships, patterns, and trends in data across different locations. This tool has played a vital role in the development of geotechnical engineering by enhancing decision-making processes and improving project efficiency.
