Source data for each indicator was obtained from a range of sources, scales and data formats, including some non-spatial. Given the data sources no guarantee of the accuracy or completeness of the maps and GIS layers derived from the source layers can be provided. The supplied information was pre-processed into a consistent format to enable layers to be combined together. From the pre-processed source data Indicator layers were created from one or more source layers. Each indicator layer covers the full extent of the project area. As each source dataset was at a different spatial resolution indicators were joined or “rolled” into SA1 census regions with each census region receiving the highest sensitivity ranking for that indicator. When more accurate or up to date data becomes available it is a simple process to re-create the indicator layers and re-run the multi-criteria analysis to form the three sensitivity and adaptive capacity layers. The source of each data layer is stated in Table 17.
