ortho_debs

ORTHO_DEBS contains high resolution QuickBird orthorectified satellite imagery from Digital Globe. The data are presented in 3 8-bit bands with pixel resolution of 60cm and horizontal accuracy of 2.3m. These digital images result from pan-sharpening of multispectral data to panchromatic data, followed by orthorectification and mosaicking of digital satellite image scenes. The images were collected July 13, 2005, Sep 5, 2005, Sep 28, 2005, and Oct 29, 2005, by the QB02 Satellite using the QB sensor at an altitude of 450km. Each pixel represents a planimetric square 60cm on a side on the ground. The satellite data are presented in 3 bands (3 = blue light 450-520nm; 2 = green light 520-600nm; 1 = red light 630-690nm). The data are pan-sharpened from Quickbird's multispectral (4-band) 2.44m sensor to the 61-cm panchromatic (445-900nm) sensor using an algorithm from ESRI. The data were resampled to 60cm pixels during the reprojection process to UTM Zone 19N NAD83, which is the current projection. Each band is captured in 11 bits and presented here as 8-bit. The images were radiometrically balanced to the extent possible (limited by vastly different collect dates) to provide a smooth mosaic. Orthorectification was completed using the National Elevation Dataset as the terrain reference. The accuracy and quality of the Digital Globe orthoimagery meets National Map Accuracy Standards at 1:3,600 scale, plus/minus 3 meters or 10 feet, and is accurate for mapping applications at 1" = 300'.
