GIS web services provide direct access to data, eliminating the need to download a dataset and import it into your desktop application, instead using a simple HTTP interface (URL) to access the data. The department uses a variety of service protocols including Web Map Services (WMS), Web Map Tile Services (WMTS) and Web Feature Services (WFS) provided by the Open Geospatial Consortium (OGC) and ESRI web mapping services.

Datasets available as OGC web services include drillholes and mineral occurrences.

Datasets available as ESRI web services include the coalfields, major operating mines, 1:1.5 million statewide surface geology map and seamless geological mapping data.

How to use GIS web services

The URLs below for WMS, WMTS and WFS services are the service endpoint URLs. They will not resolve in a simple web browser (like Internet Explorer, Chrome, or Firefox). The service endpoint URLs can be used in desktop mapping applications (eg, QGIS, ArcGIS, MapInfo) and specialised web portals like the Geoscience Portal.

For more information on how to use GIS web services in QGIS, ArcGIS and MapInfo mapping applications please read the GIS Web Services User Guide.


As with all other Australian geoscience agencies, New South Wales aims to deliver WFS data as OGC-compliant interoperable protocols using the international standards GeoSciML and EarthResourceML for boreholes, mines and mineral resources. Currently a simplified version of EarthResourceML called MinOccML is used for mineral occurrences.
