Why Hydrographic Data Infrastructure is a priority
Hydrography is the measurement and description of the seabed and adjoining coastal areas. LINZ is the Government's steward of core hydrographic information that is produced primarily to support navigation and safety of life at sea. It also underpins the study, management and exploitation of the country's marine resources. This information is collected, managed and distributed in the context of standards and agreed areas of national responsibility co-ordinated by the International Hydrographic Organisation.
The current infrastructure supporting the capture, access, management, maintenance and distribution of this information was identified as needing improvement to ensure LINZ continues to meet its responsibilities and future requirements. The HDI project will deliver LINZ the capability to respond to huge increases in the volume of survey data being produced by new technologies. LINZ will be able to deliver products more efficiently and meet customers' increasing expectations through the use of modern database technology.
The first phase of the HDI project is now complete. It established the concept and rationale for HDI, including defining and improving LINZ's processes and capabilities, data agreements, role and responsibilities, capacity and competencies, standards, products, services, and user requirements.
The second phase is the implementation of key hydrographic systems. This is planned for 2007/08 and will enable the delivery of products and services to customers in later years.
Contribution to end outcomes
Availability of land information.
Contribution to intermediate outcomes
Convenient access to integrated land information that is:
- discoverable - meaning it is well indexed, information is easy to find and the source of the data is understood
- convenient to access at reasonable cost
- fit for the purpose for which it was collected
- interoperable - meaning it can be combined with other land data, and
- collected once but able to be used many times.
In 2007/08 LINZ will begin implementing a new infrastructure that will improve the management of hydrographic data and produce products more efficiently. This includes:
- developing and implementing hydrographic database applications and processes, and
- capturing and translating hydrographic metadata and core datasets into the new databases, ensuring all databases are updated as future data arrives into LINZ, and enabling the provision of data using electronic channels.
