    EXECUTIVE SUMMARY

    The Estate and Infrastructure Group (E&IG) Spatial Data Management Plan (SDMP) has been developed to provide standards and specifications for spatial data management.

    The standards and specifications within the SDMP will improve data consistency and availability of information, and facilitate spatial information dissemination and sharing within E&IG. With its use, E&IG will achieve a standardised approach to spatial data management that will realise many benefits to both the organisation and its staff including:

    Consistent and more reliable data that will lead to more informed decision making; Closer integration with other E&IG information systems and Defence spatial data users; Portability of staff skills; and Greater interoperability with organisations outside of Defence.

    The SDMP shall be used by spatial data users both within Defence and Defence Contractors, and data managers within E&IG. It is the responsibility of data users to implement the SDMP Specifications and produce data in accordance with the specifications. Data Users shall implement all requirements defined in Section 2, and the specific data requirements in Sections 3 onwards as determined by the type of data to be created or updated.

    The SDMP is made up of three main Sections:

    Section 1 provides an introduction to the SDMP, the scope of implementation and other background information to the document.

    Section 2 contains the General Data Specification that describes data formats, file naming conventions, metadata requirements, the approved datum and coordinate systems, measurement units, accuracy and other E&IG data standards.

    Sections 3 onwards contain a set of specific data type specifications that shall be implemented by all spatial data users. The data specifications cover the key E&IG data types, the Master Site Plan and the Spaces (Floor) Plans, in addition to specifications for engineering detail survey, aerial photography, master planning, environmental data and other data types.

    Appendices support the SDMP, providing detail of the E&IG Spatial Data Management Specification, the full Metadata Specification and additional appendices to support the core data specification and data type specifications. Table E-1 summarises the information held within each Section and Appendix.
