Draft Geospatial Metadata Standard
| This draft standard is currently undergoing inter-agency testing. This testing may result in further refinements of the standard. It is being published in its current form to enable comments by other agencies. |
A cross-agency team led by Land Information New Zealand (LINZ) has developed a geospatial metadata standard to consistently describe geospatial information (GI) across New Zealand government agencies. The initiative builds on recent and current e-government work on the New Zealand Government Locator Service (NZGLS) and Interoperability Framework (e-GIF), which are key components of the e-Government work programme.
Metadata has been identified as an important mechanism that will enhance the knowledge of GI within New Zealand. The requirement from the e-Government strategy is to: "Develop consistent ways of describing place information across New Zealand government agencies, making it easier to find location-related information through the portal." The standard defines the metadata elements required to support enhanced data discovery and the development of GI access.
The development of this standard draws on experience gained from previous geospatial projects, such as the Environmental Reporting Programme (Ministry for the Environment) and the Emergency Services and government Administration project (ESA). These projects used geospatial metadata components defined by a technical committee of the International Organisation for Standardisation (ISO/TC211). The resulting standard is published as ISO 19115:2003.
Presently, a spatial search for geospatial information using NZGLS only uses one element - 'coverage'. Due to the inherent complexity of GI a greater number of descriptive elements are required to encode and then successfully search geospatial metadata. The guidelines show how NZGLS elements match this profile.
Draft NZ Geospatial Metadata Profile and Guidelines are available in PDF format.
Latest Draft
Draft Profile refinements |
PDF (1.5 MB) * |
Revised NZ Geospatial Metadata Profile - incorporates concepts consistent with a proposed draft Technical Specification being work item 19139 - Metadata Implementation Specification (DGIWG v0.8) and refinements to resolve current inconsistencies between the NZGMS and ESA metadata profiles. The revisions include the UML definitions (words and class diagrams) of these metadata profiles found in both the main body of these specifications and their appendices. |
Draft Guidelines |
PDF (1.9 MB) * |
This document is a guide to use the Draft Geospatial Metadata Standard. |
Schemas |
XML Schema Definition (XSD) (includes .zip file) |
The XML schemas to describe the New Zealand Geospatial Metadata Standard. Two versions of XML schemas for each metadata profile have been formulated; the first to include ONLY the elements prescribed for each profile ("Conform 1"); and a second version ALSO including other ISO 19115 metadata elements identified as "optional" or "conditional" in ISO 19115 but not included in the profiles. |

Draft Profile |
PDF (446 KB) |
The profile defines a geospatial metadata standard applicable for the gathering, describing and storing of geospatial metadata. Government Agencies will be encouraged to use the standard to describe their GI. The data format for recording the information is XML, consistent with the NZ e-GIF. |
Draft Guidelines |
PDF (620 KB) |
This document is a guide to use the Draft Geospatial Metadata Standard. These guidelines have been produced to aid New Zealand Government Agencies understand metadata and be able to capture metadata records for their own GI. |
