A Spatial Data Infrastructure (SDI)[1]​ integrates data, metadata, web services (WMS, WFS, WCS...) and geographic information to promote its use.

An SDI is the set of technologies, policies, standards and human resources to acquire, process, store, distribute and improve the dissemination of geographic information.[2]​[3][4]​ Just as roads and highways facilitate the transportation of vehicles, SDIs facilitate the transportation of geospatial information. SDI promote the social, economic and environmental development of the territory[5]​.
