Hydro Line 2012 Strahler Stream Order Classification

This dataset represents a stream network (centreline) of features both natural and artificial across NSW, classified using the Strahler Stream Order method, undertaken by the Department in 2013.

This is a legacy, best endeavours dataset based upon a static (2012) copy of the now NSW Department of Customer Services (DCS) | Spatial Services: NSW Hydro Line. Today this data forms part of the NSW Digital Topographic Database and NSW Foundation Data Framework administered by DCS.

Classification of the stream network was completed using the &apos;RivEX&apos; tool (www.rivex.co.uk) in combination with ESRI ArcMap by the Departments Geospatial practitioners.

Method

The dataset was initially broken down against 13 Catchment Management Authority (CMA) catchment boundaries (as at 2012), or smaller subsets to aid RivEx processing, which closely aligned to hydrological catchments. The edges of the subsets were checked to ensure hydro lines fell within the correct hydrological unit.

Catchments were processed (classified) in order of stream flow to ensure the order at the end of one catchment was used as the beginning of any it flowed into.

For Victorian and Queensland datasets - any stream that flowed into NSW waterways were extracted (by complete catchment) and processed in exactly the same way as the NSW hydro lines data. Queensland was processed first so the Strahler results could be incorporated in the northern catchments of NSW. Victorian streams were processed before the NSW Murray &amp;amp; Lower Murray Darling areas to ensure continuity of stream order application in NSW. 

 A summarised workflow is provided below: 


Input dataset: 2012 DCS NSW Hydro Line
Break the input dataset into manageable catchments for processing
Complete topology checks (ArcMap) on catchment subsets
Undertake basic hydrological enforcement by flipping geometric line directions where required to align with stream flow / class order direction.
Run Strahler processing (RivEX)
Undertake visual quality assurance of results &amp;amp; manually resolve issues.
Recombine catchments to assemble a statewide dataset
Output dataset: Hydro Line (2012) Strahler Stream Order Classification NSW

Note: Victorian and Queensland data was also sought (best available) so accurate Strahler assessments at the State borders could be assessed.

PTAL (Public Transport Accessibility Level)

Public Transport Accessibility Level (PTAL) is a measure of connectivity by public transport and is used for various planning processes. PTAL suggests how well a place is connected to public transport services. It does not cover trips by car.

The TfNSW PTAL model calculates public transport accessibility for every Australian Bureau of Statistics Mesh Block in New South Wales (NSW). The TfNSW PTAL model is based on the Transport for London (TfL) and was adapted for TfNSW in collaboration with the Spatial Information Science team at the Department of Earth and Environmental Sciences, Macquarie University. The full details of the TfL PTAL model can be found here.

PTAL values range from zero to six, where the highest value represents the best connectivity. PTAL is available for each hour of the day.

A location will have a higher PTAL if:

-  It is a short walking distance to the nearest stations or stops

-  Waiting times at the nearest stations or stops are short

-  More services pass at the nearest stations or stops

-  There are major rail stations nearby

-  Any combination of all the above.

Please read the PTAL Fact sheet for more information. The format of the data is ArcGIS geodatabase.

Please be advised that an issue was identified with the PTAL 2024 file. Necessary corrections have been made and the updated file is now available, please download the latest version.

The images below are examples of PTAL data in 2024.

Spatial analysis of child deaths in New South Wales

The NSW Child Death Review Team (CDRT) works to prevent and reduce the deaths of children aged from birth to 17 years. To do this, we maintain a register of child deaths occurring in NSW and analyse information about these deaths to identify any patterns or trends. One pattern we need to understand is the geographic distribution of child deaths in NSW, and how this may vary by cause of death and the characteristics of geographic areas.

In 2016, we engaged the Australian Institute of Health and Welfare to undertake geospatial analyses of the 8,657 deaths of children that occurred in NSW between 2001 and 2015. This report details the findings of that work.

NPWS Estate
Land Vested in NPW Act Minister - acquisition of land for reservation
Land Vested in NPW Act Minister - acquisition of land for management and other purposes
NPWS Managed Land Other
This combined dataset is for reporting purposes when it is deemed necessary to include all of the land that is managed by NSW National Parks and Wildlife Service.
Area hectares of each polygon have been generated in this dataset to assist reporting. Please note that the GIS area calculation was performed using Lamberts Conic Conformal (LCC) projection. This GIS calculated area will not be the same as the gazetted area or acquired area.
The following is the description of layers included:

The NSW National Parks and Wildlife Service (NPWS) Estate database provides information on areas reserved under the NP&amp;W Act 1974. Areas include National Parks, Nature Reserves, Regional Parks, State Conservation Areas, Aboriginal Areas, Historic Sites and Karst Conservation Reserves.
Land Vested in NPW Act Minister - acquisition of land for reservation - Boundaries of areas in NSW which are vested in the Minister administering the National Parks and Wildlife Act 1974 under Part 11. The majority of lands included in this dataset are acquired by the NSW NPWS but not yet gazetted as formal reserve. This dataset is known internally as NPWS Acquired Not Gazetted.
Land Vested in NPW Act Minister - acquisition of land for management and other purposes - Boundaries of areas in NSW which are vested in the Minister administering the National Parks and Wildlife Act 1974 under Part 11. This dataset contains all other vested lands that are not included in the NPWS Vested For Reservation dataset. This dataset includes access roads, workshops, depots, accommodation, offices, leasehold land, and land pending decision or disposal.
NPWS Managed Land Other - Boundaries of other land in NSW which are under the management of the NSW NPWS. Areas include Crown land under licence to NPWS, Crown Reserve managed by NPWS, Flora Reserve managed by NPWS, and Enclosure Permit held by NPWS. This dataset is known internally as NPWS Managed Land Other.
Additional fields have been added to the attribute table of the merged dataset to assist in determining management responsibilities. These are:

SOURCE: Source of the individual tenure layer from the above four datasets
TENURETYPE: Lists different tenure types eg. Reserved, Freehold, Leasehold, Crown land under licence to NPWS, Enclosure Permit held by NPWS, etc

Menai area traffic study

This study was commissioned by the Roads and Traffic Authority (RTA) to investigate the strategic needs of the major road system in the Menai area. The study area is shown on figure 1.1. The Menai area is going to be the focal point of substantial residential development in the forthcoming decade and beyond and the effect of this development will be to increase vehicular trip making for a number of trip purposes (ie. work, shop, educational and social) to adjacent centres such as Sutherland, Liverpool and Bankstown. The existing centres of Sutherland and surrounding areas therefore require direct road connections to the adjacent centres mentioned above.

New Grafton bridge : post-construction operational noise report

The Clarence River Bridge Crossing project in Grafton involved the construction of a new bridge crossing over the Clarence River in Grafton to improve traffic flow for the areas to the south and north of the river, with the existing bridge being retained to provide a crossing for local traffic.
Key features of the new Clarence River Crossing (new Grafton bridge) project include a new 525-metre long bridge, 70 metres downstream from the existing road and rail bridge, to provide a second crossing of the Clarence River.  The new bridge connects to the existing road network in Grafton and South Grafton.  Construction of the project started in November 2016, and it was opened to traffic in December 2019.
During the pre-construction phase of the project, predictive noise modelling was carried out to determine the likely road traffic noise levels expected from the project.  The results of the noise modelling for the project were presented in the detailed noise modelling and assessment report (ref. TJ502-01F07 (r7) Noise Modelling &amp; Assessment, dated 29 March 2018).
