NSW Imagery Basemap Service

NSW Imagery Basemap 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 with a “GDA2020 suffix” (e.g. ‘NSW_Imagery’ => ‘NSW_Imagery_GDA2020’).

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 2018  imagery

This web service allows users to easily integrate a geographical index of the features described above. When used in conjunction with other mapping datasets, it can be an excellent referencing tool for determination of imagery coverage and approximate dates over any given area in NSW. This service allows the user to enquire on any point in NSW and have imagery coverage and approximate dates returned.

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

Web service uses/fitness for purpose

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 DCS Spatial Services and is an output of Spatial Services’ imagery collection and maintenance program.
