NSW Imagery Web Service GDA2020

GDA2020 Cached Map Tile service - See GDA2020 Web Services Information Sheet and GDA2020 Raster FAQ

This Cached Map Tile service is published with a spatial reference of WGS 84-aligned-to-GDA2020). For users who require a [WGS 84-aligned-to-GDA94] service the original NSW Imagery Web Service is still available.

Disclaimer: This Cached Map Tile service is created directly from the GDA94 Cached Map Tile service by simply shifting pixels by a distance equivalent to the GDA94 > NTv2-CPD > GDA2020 transformation. This shift must be a whole number of pixels. As a result, where raster tiles are provided at low-resolution, the display location may differ from true GDA2020 location. For example, a tile at ‘zoom level 18’, with 60 cm pixel resolution, may appear offset from GDA2020 by ~30cm.

The NSW Imagery web map service provides spatial imagery covering the extent of NSW. It depicts a cached imagery map of NSW which includes the following data sets:

LandSat 2014® satellite imagery
Spatial Services standard coverage ADS sensor orthorectified imagery
Spatial Services high resolution ADS sensor town imagery
Spatial Services high resolution ADS sensor project imagery
AAM 2012 Tweed orthorectified imagery
AAM 2012 Sydney conurbation 10cm GSD orthorectified imagery
Jacobs 2009 Upper Hunter AUSIMAGE® orthophoto imagery
Jacobs 2004 Queanbeyan AUSIMAGE® orthophoto imagery
Jacobs 2006 Yass AUSIMAGE® orthophoto imagery
Jacobs 2002 Goulburn AUSIMAGE® orthophoto imagery
Jacobs 2014 AUSIMAGE® orthophoto imagery
Jacobs 2016 AUSIMAGE® orthophoto imagery
Spookfish/Eagleview 2018 Imagery.

The NSW Imagery web service provides spatial imagery covering the extent of NSW progressively from scales larger than 1:150,000 higher resolution imagery overlays lower resolution imagery and most recent imagery overlays older imagery within each resolution.

This product has been produced to identify visible land cover features and terrain to support Spatial Services along with local and state government programs, including Emergency Services. This product is used on a whole of government basis as a visible record of the landscape at a given point in time.

This web service allows users to easily integrate the Imagery coverage for NSW into Open Geospatial Consortium (OGC) compliant spatial platforms and applications.

Imagery provides an analytical source and contextual background for decision making and supports multiple applications including:

mapping
emergency services
sustainable human and land use development
geosciences
natural resource management

The NSW Imagery web service provides access to accurate, authoritative and timely aerial imagery of NSW.

This service ensures users are able to consume spatial imagery without the requirement of hosting the imagery files on their own servers. The Imagery cache is maintained by Spatial Services and is an output of Spatial Services’ imagery collection and maintenance program.
