NSW Administrative Boundaries Theme - Parish

Access APIAdministrative Boundaries Theme - ParishPlease Note WGS 84 service aligned to GDA94 This dataset has spatial reference [WGS 84 ≈ GDA94] which may result in misalignments when viewed in GDA2020 environments. A similar service with a ‘multiCRS’ suffix is available which can support GDA2020, GDA94 and WGS 84 ≈ GDA2020 environments. In due course, and allowing time for user feedback and testing, it is intended that the original service name will adopt the new multiCRS functionally.NSW Parish is a dataset within the Administrative boundaries theme of the FSDF. It contains 7,459 administrative areas (Parishes) formed by the division of 141 counties. Counties and parishes are administrative divisions of the state and are not separately disposable land parcels. County and Parish are historical layers and the information contained on these layers was gathered from Parish and County maps which are now held at State Records (digital versions can be accessed through the Historical Lands Records Viewer). However, they can be updated (if necessary) after a title inspection.Parishes are divided into separately land parcels called “portions”, these being the common basic units of land disposed of by the Crown (sold), held in occupation (leased) or reserved for public purposes. Other basic units are section and allotments in Towns and Villages. The dataset contains county and parish names. Any changes that occur to the dataset should have a reference in the authority of reference feature class in the lot and property data sets.

Features are positioned in topological alignment within the extents of the land and property polygons for each county and are held in alignment, including changes resulting cadastral maintenance and upgrades. NSW Parish is a subset of NSW County.This dataset contains an historical land administration boundary. The original Parish definition is static, however, data will move with changes to the Land Parcel and Property theme.

Relationship to Themes and Datasets  

Administrative Boundaries Theme of the Foundation Spatial Data Framework (FSDF)  

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.

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.
