Select a layer to view its associated meta data.

The layers in this category (e.g. cartographic text, transport and water) can be overlaid on your map as contextual information.

Crop suitability assesses how well an environment supports specific agricultural activities by analysing geo-referenced climate, soil, and terrain data. The method used for these layers is adapted from Kidd et al. (2015), and uses GIS rules and simplified parameter ranges to estimate suitability. It translates biophysical attributes into suitability indexes for crops, considering factors like temperature and soil pH. Suitability classes (well-suited, suitable, marginally suited, and unsuitable) are assigned based on these indexes, with the overall suitability determined by the worst limiting factor. Experts refine these rules through iterative evaluations to ensure sensible spatial patterns. The soil information is derived from a combination of S-map and the fundamental soil layers (FSL), both from Manaaki Whenua – Landcare Research. The soil data is resampled on a 500x500m grid. The climate data is the 5x5km Virtual Climate Station Network (VCSN) grid from NIWA.

Yield information can be accessed in the GET REPORTS panel by dropping a pin on the map. Yield ranges for each suitability class are estimated by crop experts, with well-suited yields based on maximum observed field yields in New Zealand, suitable yields on national averages, and marginally suited yields varying by environmental conditions. Unsuitable areas predict zero yields or uneconomic harvests.

This dataset was produced as part of the Land Use Opportunities: Whitiwhiti Ora research programme funded by the Our Land and Water National Science Challenge. Further information about this layer and links to download the data, can be found at the Whitiwhiti Ora Data Supermarket.
