Processing/Boresighting
v3 v4 25 25 26 26 As a good starting point it is useful to use the opposite flight direction flight lines to solve for roll and pitch. As a roll error will manifest itself as an across track shift and a pitch error as an along track shift. Be wary though that heading errors will also appear as a mixture of across and along track shifts. Heading errors are best identified using parallel lines with a 50% along track overlap. 27 28 29 == LiDAR Boresight Procedure ==#Lidar 30 31 [[Image()]] 32 33 === Flight requirements: === 34 35 * Multiple flight lines taken along different flight paths at different altitudes 36 * Opposite and overlapping: e.g. a line North and a line South 37 * Parallel and overlapping: e.g. 2 lines East 38 * Ideally 4 or 5 lines each from at least 2 or 3 altitudes: 750m, 1350m, 2200m 39 40 Typically we will collect 11 or 12 lines going N, S, E and W taken at different altitudes. 41 42 === Processing technique: === 43 44
