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 > GDA2020
o    GDA94 < NTv2-CPD > WGS 84 aligned to
GDA94
o    GDA2020 < NULL > WGS 84 aligned to GDA94
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:Â 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.Â
They include:Â
ParishÂ
CountyÂ
SuburbÂ
Local Government AreaÂ
State Electoral District Â
Federal Electoral DivisionÂ
Mines Subsidence DistrictÂ
NSW Parks and Wildlife Service ReserveÂ
State Forest Â
Domestic Water Front Precinct
The Administrative Boundaries theme is used to show administrative areas
that represent:
Voting DistrictsÂ
RedistributionsÂ
ZoningÂ
Socio-Economic analysisÂ
Regional PlanningÂ
Service DistributionÂ
Local and State Government
BoundariesÂ
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.Â
The use of this data in combination with other data includes: Â
Evidence-based development and assessment of
government policyÂ
Providing the ability to undertake spatial
accountingÂ
Regional analysis for government, health,
education, business and a range of other purposesÂ
Support for emergency managementÂ
Market catchment analysis, micromarketing,
customer analysis and market segmentationÂ
Emergency management.Â
Update frequencies vary for each dataset.
Individual current status can be found under each spatial
data profile.Â

AccuracyÂ
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. Â

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
