To increase the confidence in, and usefulness of spatial cadastre data, the Intergovernmental Committee on Surveying and Mapping (ICSM) has produced a Standard for the Accuracy of Spatial Cadastres in Australia and New Zealand, along with a Supporting Document. The Standard establishes targets and a reporting framework for acceptable Positional Uncertainty (PU) for the horizontal position of parcels within spatial cadastres. The Standard requires PU to be attributed to points, lines and/or polygons within the spatial cadastre. The target PU for parcels in central business districts is 0.05m; urban, peri-urban and industrial areas 0.2m; rural areas 0.5m; and pastoral and remote areas 5m.
