Access API

Please Note

WGS 84 = GDA94 service

This dataset has a spatial reference of [WGS 84 =
GDA94] and can NOT be easily consumed into GDA2020 environments. 


The
Wollongong 1955 imagery was flown by Adastra on 11 &amp; 17 January 1955, using
an Eagle IX camera with a focal length of 152.4mm. 

The 331 frames used in the Wollongong
1955 mosaic were aerotriangulated as one block using control points that appear
in the 1955 photography and still exist today. Coordinates and heights for these
control points were obtained from modern orthophotography and LiDAR datasets.
The Wollongong mosaic was processed and produced in GDA2020, Zone 56 coordinate
system.

The frames were mosaiced
using a semi-automated seamline generation and colourbalancing workflow. Manual
QA has been completed along every seamline and manual fixes were applied to the
orthomosaic where necessary. 

Assessment of horizontal
accuracy for the Wollongong 1955 mosaic found the accuracy within urban areas
to be +/- 2m at 95% CI. Accuracy may diminish in rural areas on the outskirts
of the dataset due to lack of common control points, and issues with frame scan
quality.

Current and historic imagery form an important part of the NSW
Foundation Spatial Data Framework and provide a valuable resource which is
widely accessed by government and the broader community on a daily basis. As
the completeness of this data base continues, its market demand also increases
across a broad range of applications.

Spatial Services aerial imagery was
originally captured using a variety of cameras including the Wild RC-5, RC-10
and Leica RC-30 cameras with a variety of lenses with focal lengths of 88mm,
153mm and 304mm. Images were captured in monochrome or colour during this
period at a range of scales. Capture scales ranged from 1:5 000 to 1:80 000.

The Historical Air Photo Enhancement program (HAPE) not only
allows the capability to search, discover and use source imagery, but also
provides the delivery and viewing of enhanced historic rectified imagery
mosaics. This new development means the community at large can now access and
utilise spatially accurate historic imagery:

1.   Through
the Historical
Imagery Viewer

2.   Directly in a
wide range for GIS Mapping applications as a Web map Tile Service (WMTS).
See below for instructions

3.   Order the JP2
Mosaics direct and use locally. Contact us via the Customer
Hub.
