NZSoSDEM v1.0 is a Digital Elevation Model (DEM) covering the whole of New Zealand at a spatial resolution of 15m, created by the School of Surveying by interpolating LINZ topographic vector data.

The DEM was created as a series of 30 maps which extent correspond exactly with the LINZ Topo250 topographic map series. Smaller regions can thus be obtained individually but also fit together seamlessly to create a full countrywide DEM.

The accuracy of this product was comprehensively assessed using a statistically sound selection of 3791 check points throughout the country. The comparison of results with other available country-wide DEM demonstrate an improvement of NZDEM_SoS_v1.0 in terms of quality that comes in addition with a finer spatial resolution.

A full description of the interpolation/assessment process can be found in the attached documentation: Columbus, J.; Sirguey, P. & Tenzer, R. (2011), 'A free, fully assessed 15-m DEM for New Zealand', Survey Quarterly 66, 16-19.

0.125m GSD RGB orthophotography captured with NZAM's Microsoft Vexcel Digital Camera during March 2007. The positional accuracy of features on the ground is +/- 0.3m (90% confidence interval). Colour infrared (CIR) imagery was captured concurrently with this project, for more information about CIR imagery email support@nzam.com.
