New 2006 Adelaide Metropolitan aerial
photography ensures the latest high resolution Orthophotography
coverage
AEROmetrex Pty Ltd has completed the aerial photography program
of updating the high resolution orthophotography of
metropolitan Adelaide.
Photographed during mid
February 2006, the new Vexcel UltraCamD large format digital aerial camera
with imagery captured at 15cm pixel resolution,
the coverage extends from Gawler in the north to Sellicks Beach
in the South and includes the east - west extent from the Adelaide Hills
to the metropolitan coastline.
This complete coverage will provide some 2,000 1km
x 1km tiles of 15cm pixel high
resolution orthophotographs.
The digital camera offers 16-bit resolution in all 4 bands,
(red, blue, green and near-infrared) with the imagery being supplied as 8-bit
colour digital orthphotography in high resolution formats either as tiles
or as an .ecw mosaic that will suit all spatial software packages.
Digital photogrammetric aerotriangulation using ground
control and massive redundancy of photogrammetric “tie”
control from stereo models has facilitated the generation
of high precision 15cm pixel the digital orthophotographs.
Applying specifically written software, the AEROblend
process takes into account the radiometric (intensity
and colour) differences between photographs to ensure
seamless joins between
images and tiles.
Such is the high resolution and with a spatial accuracy
of 0.2 metres, features
such as playground equipment, sewage pit covers, traffic
and telegraph poles are easily identified providing
a valuable and graphic tool for local government and
utilities in asset management.
