Induration 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 koordinates.com/#/layers/?q=LENZ for to access these layers).
Induration is a measure of how hard the soil is and is quantified by how much force is needed to break the soil. The data defines the induration based on the soil information (from the NZLRI) and the mapped parent material. This induration data layer is differentiated into five classes, Non-indurated (Class 1), Very weakly indurated (2), Weakly indurated (3), Strongly indurated (4), Very strongly (5). 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.
