Layers: Description: There are four main data fields. 'AREA' gives the extent of each polygon in square metres. 'Feature' identifies the Fault Avoidance Zonation unit type, based largely on the 'TYPE' field in the Ground Deformation Map dataset. 'FAZ_class' identifies the category of fault complexity, as set out in Table 2 of the report. 'NAME' identifies the fault or other landform unit with which the FAZ unit polygon is associated. This dataset was compiled for presentation at a scale of 1:35,000 in the report, but the data were captured at more detailed scales. The dataset is derived from the ground deformation classes dataset. Accuracy of the polygon boundaries is the same as for the Geomorphologic map unit dataset. The geomorphologic map units were drawn on-screen at a scale of approximately 1:10,000, except for tectonic landform map units, which were mapped at ~1:5,000 scale. Locations of the boundaries of the map unit boundaries are considered to be accurate to about +/- 30 m, apart from the tectonic landform unit boundaries, which are considered to be accurate to +/- 10 m at best on the younger river terraces (Okuku Terrace 3/Makerikeri Terrace 2 and younger), but are no better than +/- 20 m on older terrace or hill landforms. The data structure and accuracy is identical to the Fault Avoidance Zone dataset, with the addition of the field 'BUFF_DIST' which states the width of the added buffer (20 m in all cases).
