NSW Administrative Boundaries Theme multiCRS

Access APINSW Administrative Boundaries Theme multiCRSMultiCRS service - supporting requests in multiple Coordinate Reference Systems - Information SheetA new series of ‘multiCRS’ web services have been published to support GDA2020.  These new ‘multiCRS’ services:·         have a spatial reference of GDA2020·         support alignment with GDA2020, GDA94 or [WGS 84-aligned-to-GDA2020] GIS environments, using built-in server-side transformations:o    GDA94 < NTv2-CPD > GDA2020o    GDA94 < NTv2-CPD > WGS 84 aligned to GDA2020o    GDA2020 < NULL > WGS 84 aligned to GDA2020      Note: ESRI software will automatically align by transforming from the sourceSpatialReference (GDA94).                Other software may need to set client-side transformations from the SpatialReference (GDA2020).     Note: Client-side transformation(s) can be used to over-ride these default transformations. The original [WGS 84-aligned-to-GDA2020] is still available, without the ‘multiCRS’ suffix. In due course, and allowing time for user feedback and testing, it is intended that the original service name will adopt this new multiCRS functionally. The Administrative Boundaries theme from NSW Foundation Spatial Data Framework (FSDF) is a collection of legislative, regulatory, political, maritime and general administrative boundaries sourced from local and state boundary datasets.  They include:  Parish  County  Suburb  Local Government Area  State Electoral District   Federal Electoral Division  Mines Subsidence District  NSW Parks and Wildlife Service Reserve  State Forest  Domestic Water Front Precinct The Administrative Boundaries theme is used to show administrative areas that represent: Voting Districts  Redistributions  Zoning  Socio-Economic analysis  Regional Planning  Service Distribution  Local and State Government Boundaries  In addition, Administrative Boundaries can also be used for analysis and to look at trends over time. Administrative boundary data in combination with geo-coded address data, demographic information and agency specific business information underpins the ability to perform high quality spatial analysis.  The use of this data in combination with other data includes:   Evidence-based development and assessment of government policy  Providing the ability to undertake spatial accounting  Regional analysis for government, health, education, business and a range of other purposes  Support for emergency management  Market catchment analysis, micromarketing, customer analysis and market segmentation  Emergency management.  Update frequencies vary for each dataset. Individual current status can be found under each spatial data profile.

Accuracy 

The dataset maintains a positional relationship to, and alignment with, the Lot and Property digital datasets. This dataset was captured by digitising the best available cadastral mapping at a variety of scales and accuracies, ranging from 1:500 to 1:250 000 according to the National Mapping Council of Australia, Standards of Map Accuracy (1975). Therefore, the position of the feature instance will be within 0.5mm at map scale for 90% of the well-defined points. That is, 1:500 = 0.25m, 1:2000 = 1m, 1:4000 = 2m, 1:25000 = 12.5m, 1:50000 = 25m and 1:100000 = 50m. A program of positional upgrade (accuracy improvement) is currently underway.

Standards and Specifications  

Open Geospatial Consortium (OGC) implemented and compatible for consumption by common GIS platforms. Available as either cache or non-cache, depending on client use or requirement.   Information about the Feature Class and Domain Name descriptions for the NSW Administrative Boundaries Theme can be found in the NSW Cadastral Delivery Model Data Dictionary

Some of Spatial Services Datasets are designed to work together for example NSW Address Point and NSW Address String (table), NSW Property (Polygon) and NSW Property Lot (table) and NSW Lot (polygons). To do this you need to add a Spatial Join. A Spatial Join is a GIS operation that affixes data from one feature layer’s attribute table to another from a spatial perspective.

To see how NSW Address, Property, Lot Geometry data and tables can be spatially joined, download the Data Model Document.
