Spatial Data Infrastructure (SDI) refers to the framework that enables the collection, management, sharing, and use of spatial data. It includes policies, technologies, and standards that facilitate the integration of geographic information from various sources, making it accessible to users such as governments, businesses, and researchers. An effective SDI supports decision-making and planning by providing accurate and up-to-date spatial data. It often involves collaboration among different organizations and stakeholders, ensuring that data related to geographic information systems (GIS), remote sensing, and cartography is standardized and interoperable for various applications.
