AVAILABILITY OF QMAP DATAACKNOWLEDGMENTSThe geological map accompanying lhis book is derivedfrom information slored in the geographic informationsystem (G IS) database mail1lained by the InslilUte ofGeological & Nuclear Sciences and fro m olher GIScompatibledig ital databases. The data shownon the mapare a subset of the available inform ation. Customi sedsingle-factor and multifaClar mapscan be generated fromthe GIS and integrated with other data sets to produce,forexample. maps showi ng fossil or mi neral localities inrelation to specific rock types.ormaps showing rock typesin relation to the road network. Data can be presented foruser-defi ned specific areas, for irregular areas such aslocal authori ty territori es, or in the form of stri p mapsshowing informationwithin a specified distance of linearfeatures such as road s or the coastline. The informationcan be made available at any required scale bearing inmind the scale of data capture and the generali sationinvolved in digiLising. M apsproduced at greater than 1:50000 scale will not show accurate, detai led geologicalinformation unless they are based on poi nt data (e.g.structural infomlation). If required the QMAP series mapscanalso be made available in digital fonn using standarddata interchange format s.The digital data have been captured from data record mapscompi led on standard 1:50000 NZMS 260 topograph icmaps. These record maps are fil ed in GNS offices inDunedin and Lower HUll (Gracefi eld) and, althoughunpublished, are avail able fo r consultation. They arestored on transparent film and copi es can be made. Thelegend and mapping philosophy used for the detailedmapsare based on lithostratigraphy and may differ fromthose used on QMAP.For new or additional information, for pri ntsof thismapat other scaJ es, for selected data or combi nationsof datasets or for deri vati ve or single-factor maps based onQM AP dara, please contact:QM AP LeaderInSlilUle of Geological &P.

M aj or sources of infomlationincluded unpublished 1:50000 compi lations by staff ofthe former New Zealand Geological Survey, notably workby D.A. Francis, C. Mazengarb, P.R. Moore, and I.G .Speden. In particular we acknowledge the work of PhilM oore who, with and separately from the map compilers.spent many summers collecting data.
