Flight line information can be provided as a shape file using the internal project id m3803. The Leica ADS80 is equipped with a SH82 sensor head with a field of view (swath angle) of 64° and multiple linear CCD’s of 12 000 pixels each, enabling the capture of 5 spectral bands of information. These bands are; panchromatic having spectral wavelength between 465-495 λ (nm), blue (B) having a spectral wavelength between 435-495 λ (nm), green (G) having a spectral wavelength between 530-580 λ (nm), red (R) having a spectral wavelength between 610-660 λ (nm), and near-infrared (NIR) having a spectral wavelength between 840-900 λ (nm).This product has been created using a documented process which is consistent with well accepted digital image processing techniques ( Leica GeoSystems ADS80 User Manual 2010).
