NSW Base Map Web Service

Please Note
This dataset has spatial reference [WGS 84 ≈ GDA94] which may result in misalignments when viewed in GDA2020 environments. A similar service with spatial reference GDA2020 is also available as NSW Basemap Web Service GDA2020

The NSW Base Map web service depicts a map of NSW using layers from the Digital Topographic Database, the Geocoded Urban and Rural Addressing System database and the Digital Cadastral Database.

This includes:
• roads
• points of interest
• localities
• landform
• drainage
• cultural data
• parks and forests
• property boundaries
• street address numbers.

Web service uses/fitness for purpose This web service allows users to easily integrate a NSW base map into Open Geospatial Consortium (OGC) compliant spatial platforms and applications. This web service provides an ideal base map depicting a combined view of NSW Foundation Spatial Information for use within spatial applications and systems.

Current State This web service is current and complete. Update frequency As required.

Future development This web service is updated when new information has been captured or sourced by DFSI Spatial Services.

Standards and specifications OGC compliant and suitable for consumption by common GIS platforms.

This dataset is compliant with the NSW Foundation Spatial Data Framework and its specifications.

Relationship to Themes and Datasets	The NSW Base Map is made up from elements from NSW Administrative Boundaries, Land Parcel Property, Water, Transport and Geocoded Address Themes as well as Features of Interest and Physiography Categories of the Foundation Spatial Data Framework (FSDF) Boundaries
Accuracy	The dataset maintains a positional relationship to, and alignment with, a range of themes from the NSW FSDF including, transport, imagery, positioning, water and land cover. 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.
