Title

NSW Heat Vulnerability Index to ABS Statistical Area Level 1 2016

Abstract

The NSW Heat Vulnerability Index (HVI) dataset identifies areas to monitor where populations in the Sydney Greater Metropolitan Area are more vulnerable to the adverse effects of urban heat, as of Summer 2015-2016. HVI utilises indicators for exposure, sensitivity and adaptive capacity to calculate an overall heat vulnerability index. Expressed through the data, a vulnerability of 1 represents a combination of low exposure, low sensitivity and/or high adaptive capacity. A vulnerability of 5 represents high exposure, high sensitivity and/or low adaptive capacity. The calculation of HVI and the inputs to the exposure, sensitivity and adaptive capacity indicators are explained in the metadata. The HVI data is aggregated to the Australian Bureau of Statistics (ABS) Statistical Area Level 1 (SA1) polygon dataset to enable spatial analysis to support local policy and decision making. It can be used in conjunction with the NSW urban vegetation cover dataset for the same time period for broader analysis of the relationship of heat to green cover.

ArcGIS Layer files for mapping Urban Heat Island and Heat Vulnerability Index

Name: ArcGIS Layer files for mapping Urban Heat Island and Heat Vulnerability Index

Protocol: WWW:DOWNLOAD-1.0-http--download

Description:

Layer files for symbology when using ArcGIS/ArcMap v. 10.x for displaying the dataset. The compressed file (zip) contains two layer files, one for each Urban Heat Island (manual classification of temperature ranges) and Heat Vulnerability Index (discrete attribute classes 0 to 5). Temperature ranges for UHI map degrees Celsius deviation from the reference, and include less than 0 (i.e., cooler than reference), 0 to 3 degrees warmer, 3 to 6 degrees warmer, 6 to 9 degrees warmer and warmer than 9 degrees from the reference. Two colour variations of the layer file are included.

ArcGIS REST Service - Heat Vulnerability Index

Name: ArcGIS REST Service - Heat Vulnerability Index

Protocol: WWW:DOWNLOAD-1.0-http--download

Description:

An ArcGIS Server web service represents a GIS resource—such as a map, locator, or image—that is located on an ArcGIS Server site and is made available to client applications. Depending on the layers enabled, this web service allows a user to query its features and/or visualise the dataset. This service is aimed at advanced geographical information users, and will require access to geographical information system (GIS) software such as ArcGIS/ArcMap.

WMS - Heat Vulnerability Index

Name: WMS - Heat Vulnerability Index

Protocol: WWW:DOWNLOAD-1.0-http--download

Description:

Web Map Service (WMS) is a standard protocol for serving georeferenced map images over the internet that are generated by a map server using data from a GIS Database (NSW Government - Spatial Web Services Register June 2015). WMS allows a user to spatially visualise the dataset, but not query its features. This service is aimed at advanced geographical information users, and will require access to geographical information system (GIS) software such as QGIS and ArcGIS/ArcMap

Additional information source

The heat vulnerability index attribute value is modelled on three indices - exposure to heat (temperature classes), sensitivity to heat (vegetation area, road area, population density, elderly, very young, persons needing care) and adaptivity to heat (SEIFA-IRSD and SEIFA-IEO). Index data is provided at the SA Level.1. Each statistical area is rated for each index on a scale of 1 - 5. on a scale of 1 to 5 based on quintiles, 1 represents low exposure, low sensitivity or high adaptive capacity and 5 represents high exposure, high sensitivity or low adaptive capacity. A 0 (zero) indicates no population resides there (pop. density = 0).

Lineage

The dataset was developed through a contract with the Royal Melbourne Institute of Technology (RMIT). Data was developed following the methodology for "Estimation of Land Surface Temperature and Urban Heat Island effect for Australian urban centres", from Commonwealth Science and Research Organisation (CSIRO) (Report EP173542). The processed Landsat 8 imagery was integrated with the ABS Statistical Area Level 1 polygon dataset with the assistance of Western Australia University.

This includes the major urban, urban, peri-urban and other urban areas of the included Local Government Areas. The dataset has complete coverage for the Greater Sydney Region and the Local Government Areas within it.

Completeness Ommission

Date type

publication

Effective date

2019-03-12

Explanation

Local Government Area users of the data will need to double check that their known boundaries are correctly identified. In the dataset, the LGA name that is given to a Statistical Area may be inaccurate. While the Statistical Area Level 1 has a name assigned to it, it may not match entirely with the 2017 LGA boundaries The knock on effect is that the Mesh Block may not correspond to the correct District. This issue most likely occurs with more rural SA Level 1 polygons at the boundaries, such as near Campbelltown, Wollondilly or Sutherland. As adequate data validation was performed, this issue is likely minor and not affecting every LGA. An explanation of potential omissions is explained in the attached CSIRO Report.
