A Survey of Spatial Data Infrastructure

What is a SDI?

The term “Spatial Data Infrastructure” (SDI) is

often used to denote the relevant base collection

of technologies, policies and institutional

arrangements that facilitate the availability of

and access to spatial data.

The SDI provides a basis for spatial data

discovery, evaluation, and application for users

and providers within all levels of government, the

commercial sector, the non-profit sector,

academia and by citizens in general.
