No.: 24344A Date: 18 February 2015 EXPECTED ACCURACY Project specifications and technical processes were designed to achieve data accuracies as follows: Vertical data: Derived Points: 0.15 metres Basis of Estimation: Project design Horizontal data: Measured Points: <0.20 metres Basis of Estimation: System specifications ( 1/5500 flying height) Test points: Measured Points: 0.05 metres Basis of Estimation: Survey methodology used Notes On Expected Accuracy Values shown represent standard error (68% confidence level or 1 sigma), in metres Derived points are those interpolated from a terrain model. Measured points are those observed directly. Accuracy estimates for terrain modeling refer to the terrain definition on clear ground. Ground definition in vegetated terrain may contain localized areas with systematic errors or outliers which fall outside this accuracy estimate. Laser strikes have been classified into ground and non-ground, based upon algorithms tailored for major terrain/vegetation combinations existing in the project area. The definition of the ground may be less accurate in isolated pockets of dissimilar terrain/vegetation combinations. DATA VALIDATION Ground data in this volume has been compared to 192 test points obtained by field survey and assumed to be error-free. The test points were distributed in 2 groups across the mapping area and located on open clear ground. Comparison of the field test points with elevations interpolated from measured data resulted in a vertical standard error (RMS) of <0.15 m.
