The INSPIRE (Infrastructure for Spatial Information in Europe) Directive (2007/2/EC) aims to create a European Union spatial data infrastructure for the purposes of EU environmental policies, or policies and activities which may have an impact on the environment.
INSPIRE will enable the sharing of environmental spatial information among public sector organisations, facilitate public access to spatial information across Europe and create harmonised spatial datasets that can be used seamlessly in cross-border applications.

To ensure that the spatial data infrastructures of the EU Member States are compatible and usable in a Community and transboundary context, the INSPIRE Directive requires that common Implementing Rules are adopted in a number of specific areas, such as Metadata, Data Specifications, Network Services, Data and Service Sharing, Spatial Data Services, Monitoring and Reporting.
