The Spatial Data Infrastructure (SDI)

A Spatial Data Infrastructure (SDI) is a framework that organizes and manages geographic information—such as maps, satellite images, and location data—so it can be easily shared, accessed, and used by different organizations and individuals. It combines technology, policies, standards, and people to ensure spatial data is accurate, up-to-date, and available for decision-making, planning, and problem-solving. Essentially, an SDI makes diverse location-based information interoperable and readily accessible, facilitating smarter governance, efficient resource management, and improved understanding of geographic issues.
