Data Quality
Lineage Quickbird satellite imagery of Christmas Island was commissioned by the Department of Environment and Heritage in mid 2003 and supplied to the Australian Government by DigitalGlobe in March 2006. It took this long (over 2 years) due to persistent scattered cloud over Christmas Island and many sensed scenes, not being up to 'cloud free' specifications. The Quickbird satellite recorded reflectance data of the islands in the red, green, blue, near infra-red and panchromatic bands, in 16 bit format. All sharpened imagery has a resolution of 0.6m/pixel.

Three 8-bit pan-sharpened TIFFs, one for each of the three sections, containing the red, green and blue bands was supplied to GA. Each pixel on the pan sharpened imagery represents 0.6m.

Due to disk space limitations these images are stored in ECW (Enhanced Compressed Wavelet) format. The files are stored in the 'CIGIS\data\sat_imagery\ecw' directory.
Positional Accuracy The satellite imagery did not need to be shifted to match the 2006 cadastre. 
Attribute Accuracy Not Relevant.
Logical Consistency Not Relevant.
