NSW Rapid Response Imagery – Floods 2021Rapid response
imagery is captured and produced to identify visible features and terrain in
order to support emergency management decision making during and after adverse
natural events. In this case the imagery covers areas affected by recent
flooding.Additionally, the
rapid response imagery product is used on a whole of government basis as a
visible record of the landscape at a given point in time, allowing for
comparative analysis to be carried out over multiple capture dates. The imagery
was created by ortho-rectifying and mosaicing data from flight lines over the
project area captured by Spatial Services using a Leica-Geosystems ADS80
airborne digital sensor. An ECW product is created as a Standard Colour (RGB)
orthorectifed mosaic file and a JP2 file is created as a False Colour (NRG)
orthorectified file. The file size depends on the individual project area,
compression ratio and the number of bands that exist in the image.As a rapid response
product, this dataset meets the standards and accuracy specifications outlined
in December 2016 for this product type.
