Abstract: The first edition of the 1:250,000 geological map of New Zealand, published between 1957-67, is the most comprehensive and widely used source of information on New Zealand geology. Because of subsequent geological work and re-interpretation it is increasingly outdated. Ongoing discussions with users of geological maps and a review of Earth Science priorities have indicated a widespread need for an updated map series at 1:250 000 scale. It is therefore proposed to devote the resources of the Geological Mapping Section over the next decade to a revision and preparation of a second edition (QMAP), and this has been the basis of a recent successful funding application to the Foundation for Research, Science & Technology. This report has been prepared as a summary of the approach proposed for QMAP, with information on specifications and procedures, as well as an indication of the topics still under discussion. There will undoubtedly be modifications as QMAP evolves, and updated editions of this report are likely to be produced. Many of the background issues associated with QMAP have already been outlined in a widely circulated discussion paper (Nathan 1993), and need not be repeated here. The interested reader is referred to that report for more information. The QMAP programme represents a departure from traditional geological map production, in that a Geographic Information System (GIS) will be used to store, manipulate, analyse and present the geological data. Use of a GIS allows the storage and interaction of national earth science datasets, which will open new research opportunities. Formalised procedures and data structure specifications are critical to the efficient insertion, manipulation, analysis, and retrieval of dam. Part of this document aims to formalise these procedures and specifications for QMAP. This report is divided into two parts. Part One outlines the overall project, and Part Two deals with the specifications and procedures for the GIS component. (auths)
