Abstract

Multiple parallel airborne flightlines are often necessary to provide the areal coverage desired, but standardisation to a common unit such as reflectance can be difficult, particularly where errors in the transform may be propagated sequentially through adjacent flightlines. This paper proposes a method for transformation to reflectance for such multiple flightlines based on an additional orthogonal flightline. The method is demonstrated for the CASI-2 data provided by the Environment Agency as part of the NCAVEO experiment. The uncorrected and corrected data were used to estimate NDVI using various wavebands and the NDVI estimates used to predict LAI. In all cases, the corrected data produced a slightly larger correlation than the uncorrected data.
