Greater Sydney Region Urban Vegetation Cover to Modified Mesh Block 2016

Abstract

The Greater Sydney Region Urban Vegetation Cover to Modified Mesh Block 2016 provides both an area and percentage of vegetation for city blocks and infrastructure corridors in the Greater Sydney Region as of 2016. With this dataset, users can estimate tree canopy and vegetation cover in urban areas at many scales, such as mesh block, precinct, or local government area. Having current and accurate estimates of tree canopy and vegetation like this supports citizens and governments to reliably identify areas of tree canopy and confidently develop urban greening and heat island mitigation strategies and action.
This dataset provides the user with information of high spatial accuracy. The dataset uses vegetation information derived from high resolution aerial photography combined with boundary and land use information from the Australian Bureau of Statistics (ABS) Mesh Block polygon dataset augmented with road and railroad data from the NSW Digital Cadastral Database. The content was co-designed with state and local governments and developed using scientifically-rigorous methodologies. The extent of the dataset covers urban, major urban, peri-urban and other urban areas within the Greater Sydney Region. While the dataset provides wall to wall coverage of many councils, it does not include far outlying rural areas in the Region.

Summary of vegetation for the Significant Urban Area (ABS) for the Greater Sydney Region, by LGA, Suburb and Land Zone, 2016

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

Description:

Title: Table of vegetation cover for the Significant Urban Area (ABS) for the Greater Sydney Region, summarised by Local Government Area, Suburb and Land Zone, 2016 Purpose: The table provides a summary representation of vegetation cover in metropolitan Sydney by LGA, suburb and land zone in 2016, and may be suitable for analysis of vegetation and land use for environmental planning. Description: The table depicts the area (square meters and hectares) and percentages of vegetation classes for each land zone in LGA Suburbs. Vegetation classes are defined as grass (less than 0.5 metres high), shrub (0.5 to 3 metres high) and trees/tree canopy (greater than 3 metres high). All vegetation is the sum of grass, shrub and trees. Total Area is the area used to calculate the percentages. For metadata and methodology information for the vegetation cover data, please reference the SEED record for Greater Sydney Region Urban Vegetation Cover to Modified Mesh Block 2016: https://datasets.seed.nsw.gov.au/dataset/greater-sydney-region-urban-vegetation-cover-to-modified-mesh-block Data Sources: 2016 Greater Sydney Region urban vegetation cover (NSW Office of Environment and Heritage); Environmental Planning Instrument - Land Zoning (NSW Department of Planning and Environment) - from 1 November 2016 for comparison purposes Process: Utilising ArcGIS, the urban vegetation cover data was integrated with the Land Zoning dataset. Standard Data Quality management procedures were performed on both the source data and the integration process. Limitations: This summary was generated from the source imagery using the same methodology as the vegetation cover to the modified mesh blocks. The table is to be considered as accurate as the information contained in the source datasets and reflects the land zone and vegetation cover conditions in 2016. The vegetation cover data was collected to the extent of the Significant Urban Area of Metropolitan Sydney and does not provide complete coverage for LGAs with rural areas. Noted exclusions in the vegetation cover data are rural areas in Wollondilly, Blue Mountain and Hawkesbury LGAs.

Additional information source

Data geographic extent covers all the Local Government Areas in the Greater Sydney Region. It is limited to the ABS Significant Urban Area (SUA) of the Sydney Greater Metropolitan Area (GMA). The extent of the SUA means complete and consistent coverage for the major urban, urban, peri-urban and other urban areas of the Sydney GMA. This means that there is limited coverage for rural areas, primarily in many of the outlying and heavily rural Local Government Areas within the Greater Metropolitan Area, such as the outlying areas of Hawkesbury and Wollondilly LGAs.

Lineage

The Greater Sydney Region Vegetation Cover to Modified Mesh Block 2016 is a subset of the NSW Urban Vegetation Cover to Modified Mesh Block 2016. It includes all Local Government Areas (Councils) in this Region. The NSW Urban Vegetation Cover to Modified Mesh Block 2016 is a vector polygon dataset at sub-meter accuracy, developed through a contract with the Royal Melbourne Institute of Technology (RMIT). The dataset is derived from the overlay of the NSW Urban Vegetation Cover 2016 raster imagery dataset with the Australian Bureau of Statistics (ABS) Mesh Block, modified with the road and railroad datasets of the NSW Digital Cadastral Database. The vegetation cover raster imagery dataset was produced as a digital surface model through a reclassification of high resolution (30 cm) digital aerial photography analysed using Commonwealth Science and Industry Research Organisation’s (CSIRO) Urban Monitor methodology. The analysis was conducted by CSIRO in 2018. Attention was provided to ensure minimal cloud coverage on the aerial photographs, and as a result, the flight date extends many months across 2016 to capture acceptable imagery for the full project study area extent. Quality control of the data was conducted continuously throughout the development of the data and included inspection of results and integrity testing. The Urban Vegetation Cover 2016 was overlayed with the ABS Mesh Block and the road and railroad dataset of the NSW Digital Cadastral Database (extraction dated 1/11/2016). The vegetation raster cover classification distinguishes six classes by analysing the spectral signature and elevation differences from the height of the feature to ground level - grass (less than 0.5 metres), shrub (0.5 to 3 metres), trees (3 to 10 metres, 10 to 15 meters and greater than 15 metres) and non-vegetation. Integration of the raster data with mesh block polygons was performed with the assistance of Western Australia University. This process analysed the vegetation composition within each area and derived a quantum of each vegetation class in square metres and a percent of each class by polygon. The final product was delivered to OEH to the data specifications.

Explanation

The dataset has complete coverage for the Greater Sydney Region subset of the designated Significant Urban Area of Sydney Greater Metropolitan Area. 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, with the exception of outlying, largely rural areas of Hawkesbury and Wollondilly LGAs. It also includes areas that share a boundary with the Greater Sydney Region, so that there is ensured full inclusion.

Completeness Ommission

Date type

creation

Effective date

2019-01-15

Explanation

The dataset has complete coverage for the designated Significant Urban Area of Greater Sydney Region. As such it does not provide complete coverage to LGAs which have rural areas or large areas devoted to national parks. This is largely defined as the outlying areas of Hawkesbury and Wollondilly LGAs located on the periphery of the Greater Sydney Region. This is because of the limits of the extent and completeness omissions of the Urban Vegetation Cover 2016 raster dataset. Therefore, the dataset cannot provide complete land cover/vegetation cover analysis for every LGAs in the study area.

Conceptual Consistency

Date type

creation

Effective date

2019-01-15

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 Modified Mesh Block may be inaccurate, due to the modified Mesh Blocks boundaries not nesting within the LGA boundaries completely. The LGA boundaries were overlaid with the Modified Mesh Blocks polygons and the LGA names were assigned to the Mesh Block with the greatest area within it. Note 2017 LGA boundaries were used. The knock on effect is that the Mesh Block may not correspond to the correct District. This issue most likely occurs with more rural Mesh Blocks at the boundaries, such as near Campbelltown, Wollondilly or Sutherland. It may also occur where roads form a boundary between LGAs. As adequate data validation was performed, this issue is likely minor and not affecting every LGA.
