What is a spatial data infrastructure (SDI)?

A spatial data infrastructure (SDI) is fundamentally a framework designed to facilitate the sharing and accessibility of spatial data among various users, organizations, and systems. This infrastructure encompasses policies, standards, technologies, and human resources that collectively enable the exchange and integration of geospatial data across different platforms. It promotes interoperability, allowing users to discover, access, and utilize spatial information efficiently and effectively.

The emphasis on facilitating the sharing of spatial data highlights the critical role of SDIs in supporting decision-making processes in multiple fields, including urban planning, environmental management, and emergency services, where geospatial information is vital. By standardizing data formats and improving collaboration among data providers and users, SDIs enhance the overall quality and usability of spatial data in various applications.
