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.
