Data Storage and Management
SDI provides a place to store all kinds of location-based information. This could include maps, satellite images, or any data tied to specific places.

Data Sharing
SDI allows different people and organizations to share their location data. This is important because it helps everyone access and use the same accurate information.

Mapping and Visualization
SDI helps create maps and visual representations of geographical data. This makes it easier for people to understand information about specific locations.

Analysis and Decision-Making
SDI provides tools to analyze spatial data. This is useful for making decisions in areas like urban planning, environmental management, or disaster response.

Interoperability
SDI ensures that different systems and technologies can work together. This is important because it allows data from various sources to be combined and used in a coordinated way.

Metadata Management
SDI helps organize information about the data itself. This metadata includes details like when the data was created, who created it, and how it should be used.

Standards and Guidelines
SDI establishes rules and standards for how data should be collected, organized, and shared. This helps maintain consistency and quality in spatial data.
