The primary technology used in geospatial applications is Geographic Information Systems (GIS). GIS technology enables users to capture, store, analyze, and visualize geographical data in various formats. It helps to represent spatial relationships, offering insights into geographical patterns and trends. GIS is extensively used in urban planning, environmental management, transportation, and disaster response. By integrating various data layers, GIS allows for sophisticated analysis and informed decision-making, making it essential in fields such as geography, geology, and land use planning.
