Many organizations that use GIS need to integrate data from multiple sources, organizations, and formats. A spatial data infrastructure (SDI)—which catalogs and provides access to diverse geospatial resources—expands your GIS with a framework for efficient decision making and effective operation.

Creating an SDI is a collaborative venture between public and private organizations. With ESRI technology built on open-standards, organizations can work together to build an SDI within their enterprises, or across local, national, and global communities.
