ArcGIS Layer files for mapping tree canopy and vegetation

Name: ArcGIS Layer files for mapping tree canopy and vegetation

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

Description:

Layer files for symbology when using ArcGIS/ArcMap v. 10.x for displaying the dataset. Layer files include All Vegetation, Shrubs & Trees only and Tree Canopy. Each layer file displays the percentage of each vegetation canopy group into five classes (less than 10%, 10% to 20%, 20% to 30%, 30% to 40% and greater than 40%) for the named vegetation attribute/field. Each class is a shade of green.

ArcGIS REST Service - NSW Urban Veg Cover

Name: ArcGIS REST Service - NSW Urban Veg Cover

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 - NSW Urban Veg Cover

Name: WMS - NSW Urban Veg Cover

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

Greater Sydney Canopy and Thermal Assessment 2014 and 2016

Name: Greater Sydney Canopy and Thermal Assessment 2014 and 2016

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

Description:

This report describes the production of the information derived from digital aerial photography, satellite thermal and other data for environmental and other assessments for the Greater Sydney area, New South Wales, Australia. This includes the generation of baseline information on elevations, ground reflectance, presence of vegetation and its height, and accompanying meta-data. Historic data acquired in 2016 was used representing a relatively recent capture with large geographic coverage, and data acquired from 2014 used as a caparitor year over regions of interest. The information was generated using Urban Monitor® technology developed by the CSIRO. The spatial information produced supports further analysis by State, Local, Commonwealth and other agencies and research organisations involved in greenspace and other assessments. The digital data has been provided to enable it to be combined with other datasets.

Lineage

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 designated Significant Urban Area of Sydney Greater Metropolitan Area and the major urban, urban, peri-urban and other urban areas of the included Local Government Areas. The Significant Urban Area sections that lie within the Lower Hunter, Central Coast, Greater Sydney and Illawarra Regions of Eastern/Coastal New South Wales, Australia are also included.

Effective date

2019-01-15

Explanation

The dataset has complete coverage for the designated Significant Urban Area of Sydney Greater Metropolitan Area and the major urban, urban, peri-urban and other urban areas of the included Local Government Areas. As such it does not provide complete coverage to LGAs which have rural areas and may not include large areas devoted to national parks. This is due to 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 all areas within every LGAs in the study area.

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.

Effective date

2019-01-15

Explanation

The dataset is deemed correct and consistent to the parameters of the Urban Monitor methodology, and the consistency of the NSW Digital Cadastral Database

Effective date

2019-01-15

Explanation

98% of the features are expected to be within 2% of their true size and shape.

Effective date

Explanation

Non-quantitative attributes are deemed to be accurate as of the date of the review (15/01/2019) and by explanations provided in the source datasets.
