Digital Elevation Model of Christchurch New Zealand - a 15 metre resolution, floating point precision, elevation grid generated from the LINZ 1:50,000 scale Topographic data layers (20m contours, spot heights, lake shorelines and coastline) using Landcare Research's in-house interpolation.

A 15 metre resolution, floating point precision, elevation grid generated from the LINZ 1:50,000 scale Topographic data layers (20m contours, spot heights, lake shorelines and coastline) using Landcare Research's in-house interpolation software.
This DEM was originally produced in New Zealand Map Grid (NZMG) projection with elevation in terms of the Infomap 260 chart datum (Mean High Water Spring).
It has been transformed so that the heights are floating point ellipsoidal heights with respect to the GRS80 ellipsoid; this is the standard ellipsoid for the NZTM projection.

The PRISM instrument is carried on the Japanese ALOS satellite and has three sensors that provide forward, nadir, and aft-looking views of the terrain. The forward and aft views can be combined to give stereo coverage with approximately a one-to-one base-to-height ratio, which is almost ideal for generating terrain information. The nominal spatial resolution of the ALOS-PRISM imagery is 2.5m in the forward, nadir and aft directions.
Stereo imagery has been acquired of a region in Wanganui/Manawatu area of the North Island of New Zealand. This area is currently being studied for automated soil mapping, using a variety of technologies.
This DEM represents a draft version to demonstrate progress on DEM generation from PRISM. Further developments in processing, calibration and validation are required before production of acceptable DEMs is possible.
