The last decade has seen major restructuring of official
mapping agencies in New Zealand. Until 1996 the
Department of Survey and Land Information (DOSLI) was
the principal government department responsible for civilian
and military surveying, mapping and land management.
Among the land record systems maintained by DOSLI were
the geodetic and cadastral control networks, cadastral and
topographic mapping, as well as the administration of crown
land and the provision of policy advice to government.
DOSLI split in July 1996 into two new agencies. The public
service mapping role in New Zealand is now carried out by
Land Information New Zealand (LINZ), which took over
the non-profit making parts of the Department of Survey
and Land Information. The commercial services formerly
carried out by DOSLI are now carried out under the aegis
of the government owned Terralink enterprise.
The metric (InfoMap 260) series, started in 1977 and
completed in 1996, and gives 305-sheet coverage of North and South Island.
This photogrammetric six-color map depicts relief with
20 m contours and each sheet covers a 40 km x 30 km quadrangle.
An earlier 1:63,360 scale map (NZMS 1)
was progressively withdrawn as the 1:50,000 series coverage
advanced. Sheets in the series have mainly been compiled
from unpublished (InfoMap 270) 1:25,000 scale base material,
and most of the series has been produced using conventional
cartographic techniques. The (InfoMap 260) series is
being revised on an average 10-year cycle, with a mixture
of field and photogrammetric methods.
The 1:50,000 scale digital topographic database is being
captured by scanning in three separate layers from published
(InfoMap 260) maps. These comprise hydrological detail,
cultural information and relief data and it is intended to
offer structured data for the whole country, distributed on
(InfoMap 260) tiles. The initial capture program was
completed by the end of 1997, contours were complete by
the end of 1996 for both islands and the database was
completed in 1999. Recent changes have seen a move to
object oriented map production using Laserscan LAMPS2
systems, and on demand mapping output from the database.
The first new generation 1:50,000 scale sheet was produced
in this system in 1998.
The 18-sheet (InfoMap 262) series (Terrainmap) gives complete
coverage at 1:250,000 scale. This fully metric map has relief-shading
and spot heights, and is regularly revised. The (Coast
to coast) series gives four-sheet 1:500,000 scale coverage.
1:1,000,000 maps of North and South Island are also available
(InfoMap 265). These conform to IMW specifications
and are published with or without a national parks overprint.
Soviet military topographic mapping of New Zealand is available at the following scales: 1:1,000,000 (15 sheets, complete coverage, published 1958-1973);
1:500,000 (17 sheets, primarily complete coverage, published 1978-1979) and city (1:25,000) topographic mapping of Christchurch and Wellington published between
1978 and 1984. These products are available in print, digital raster and digital vector GIS formats from East View Geospatial.
