Administrative Boundaries Theme – Mines Subsidence District

Please 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.

Mine Subsidence Districts define the area of control of the Mine Subsidence Board, which administers the Mine Subsidence Compensation Act, 1961. The Mine Subsidence Board is responsible for this dataset. Any changes that occur to the dataset should have a reference in the authority of reference feature class in the FSDF theme.

Features are typically positioned in alignment within the extents of the Land Parcel and Property dataset. Any parcel changes impact therefore this dataset.

This data is maintained from information sourced from Subsidence Advisory NSW.

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.
Spatial Reference System (dataset)	Geocentric Datum of Australia 1994 (GDA94), Australian Height Datum (AHD)
Spatial Reference System    (web service)	EPSG 4326: WGS 84 Geographic 2D
WGS 84 Equivalent To	GDA94
Spatial Extent	Full State
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.
