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.

This image comes from the European Space Agency’s Copernicus Programme taken on 10 February at 11:25 NZDT. This before image was chosen to have a similar sun angle to the after image (lris.scinfo.org.nz/layer/497-kaikoura-after-earthq... ), thus minimising differences due to illumination.

Copernicus’ six Sentinel satellites collect comprehensive pictures of our land, ocean, emergency response, atmosphere, security and climate change to understand the health of our planet. Sentinel-2 is a wide-swath, high-resolution, multi-spectral imaging mission. Its optical instrument samples in 13 spectral bands: four bands at 10 metres, six bands at 20 metres and three bands at 60 metres spatial resolution. The imagery you see on this site is derived from the four bands with a spatial resolution of 10m.

There is an on-line viewer for this and the post-earthquake image at imagery.landcareresearch.co.nz/.

The New Zealand Fundamental Soil Layer originates from a relational join of features from two databases: the New Zealand Land Resource Inventory (NZLRI), and the National Soils Database (NSD). The NZLRI is a national polygon database of physical land resource information, including a soil unit. Soil is one in an inventory of five physical factors (including rock, slope, erosion, and vegetation) delineated by physiographic polygons at approximately 1:50,000 scale. The NSD is a point database of soil physical, chemical, and mineralogical characteristics for over 1500 soil profiles nationally. A relational join between the NZLRI dominant soil and derivative tables from the NSD was the means by which 14 important soil attributes were attached to the NZLRI polygons. Some if these attributes originate from exact matches with NSD records, while others derive from matches to similar soils or professional estimates. This layer contains potential rooting depth attributes. Potential rooting depth describes the minimum and maximum depths (in metres) to a layer that may impede root extension. Such a layer may be defined by penetration resistance, poor aeration or very low available water capacity. These classes are described more fully in Webb and Wilson (1995).

Chemical limitations to plant growth data layer used in the creation of Land Environments of New Zealand (LENZ) classification. The classification layers have been made publicly available by the Ministry for the Environment (see data.mfe.govt.nz/layers/?q=LENZ for to access these layers).

This data layer defines three classes of soil based on factors that lead to the accumulation of chemicals that limit plant growth. Classes were differentiated either by their parent material or by their position in the New Zealand Soil Classification. Three classes of chemical limitations, Low (1), Moderate (2) and High (3). The class defined as "0" signifies areas where there are no soil attributes recorded (i.e. high peaks of the Southern Alps).

Additional details such as discussion about the accuracy and reliability of the LENZ soil layers and the technical definitions of the categories in this layer are defined in the attached LENZ Technical Guide.

07 Apr 2015

This dataset was first added to LRIS Portal on 07 Apr 2015.

The soil inventory survey of Wallace County, Southland was mapped at 1:50,000 scale and covers approximately 700,000 hectares of a total of 965,600 hectares. Within 6 physiographic regions, soils have been separated by differences in morphology, drainage and parent materials into 132 soil mapping units. Soils have been correlated to South Island soil sets and classification of soils for land use are provided in the attribute table.

This 1986 soil survey has been superceded in lowland areas by Topoclimate South (1998-2001) and S-map (2014) data.

Soil temperature surfaces for the South Island of New Zealand are based on analysis of a combination of monthly mean soil temperature data from the NIWA (National Institute of Water and Atmospheric Research) 3 years data from 175 mini-data-loggers (1997-2000) laid out in a stratified sampling scheme at 7 climatically representative locations in the South Island. At each location a cluster of about 25 data loggers sampled a range of elevations between 100 and 1800 m. At each elevation grouping the 4 primary aspects (N, S, E, W) and a flat site were sampled at a depth of 30cm. Multiple regression used site characteritics of latitude, Distance from coast, elevation, aspect, slope and forest/non-forest cover to predict topographic effects on soil temperatures.

New Zealand's potential forest composition was predicted from regressions relating the distributions of major canopy tree species to environment. Environmental variables, chosen for their correspondence to major tree physiological processes, included annual and seasonal temperature and solar radiation, soil and atmospheric water deficit, soil leaching, slope, and soil parent material and drainage. Environmental values were estimaged both for a large set of irregularly distributed plots describing forest composition, and points on a 1-km grid across New Zealand. Regressions were fitted to the ploy data species by species, with those for the four Nothofagus species also including terms to correct for the effects of their geographic disjunctions. Predictions of species abundance were then made for the grid data set, and the resulting matrix was classified to derive groups of similar composition. This data is expected to provide a context for both the assessment of the biodiversity value of surviving forest remnants and for the subsequent management and/or restoration of these sites.
