Brief description
Geocoded Addressing Theme - MultiCRS
MultiCRS service - supporting requests in multiple Coordinate Reference Systems -Information Sheet
A 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:
oGDA94 < NTv2-CPD > GDA2020
oGDA94 < NTv2-CPD > WGS 84 aligned to GDA2020
oGDA2020 < 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).
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 Geocoded Urban and Rural Addressing System (GURAS) is a ‘property’ based address database. Each property polygon captured within GURAS has a unique numeric identifier and contains at least one authoritative address which is sourced from local councils via the valuation of land database, also managed by LPI-Valnet. Properties may contain more than one address sourced from various other organisations.
The GURAS database is commonly used by all levels of government for emergency services, computer aided dispatch systems, postal and delivery services, and to identify location.
Address points are generally system generated points and do not always have a direct correlation to the dwelling location. In circumstances where there are multiple disparate lots for one property, particularly in rural addresses, the system generated address points may not reside within the correct property polygon. Owners names are not part of the GURAS database, nor does GURAS contain any personal information.
The Geocoded Addressing Theme is a single source of truth for address information in NSW, GURAS eliminates the costly duplication of effort where all local councils, Australia Post, emergency service organisations and other agencies and businesses maintained individual address databases with different creation and distribution regimes.
Geocoded Addressing Data Theme includes the following feature classes:
Waypoint - A WayPoint is a point located on the RoadSegment feature class for an address where the road naming attributes from both the AddressString and the RoadSegment classes are identical. Indicates the approximate entry point of for an address.
Address Point - A point feature class used to spatially locate an address / address string
The Address Point Layer includes the below subtypes:
·Building
·Homestead
·Monument
·Property
·Unit/Strata
·Other
Pro Way - A Proway is a line that spatially connects the AddressPoint and WayPoint.
The Pro Way Layer includes the following subtypes:
·Right
·Left
·Other

| 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. |
