SDIs are fast becoming a necessity for national agencies, data clearinghouses, governments etc. to setup a mechanism whereby spatial data can be readily shared, obtained, discovered and analyzed. In this day and age where spatial data is becoming ubiquitous in nature, SDIs provide a viable mechanism to attempt to bring all the stakeholders to the table.

Spatial Data Infrastructure
A Spatial Data Infrastructure (SDI) is a framework of spatial data, metadata, users and tools that are interactively connected in order to use spatial data in an efficient and flexible way. It dictates everything that is involved in setting up a central framework for spatial data. In other, more complicated words, it is the technology, policies, standards, human resources, and related activities necessary to acquire, process, distribute, use, maintain, and preserve spatial data.
