Notes On Expected Accuracy Values shown represent 68% confidence level (1 sigma), in metres. “Derived points” are those interpolated from a terrain model. “Measured points” are those observed directly.
Data Validation – Orthophoto Image This data has not been field tested for accuracy. Comparison of the orthophoto with control points which were also used in the photo orientation process resulted in a horizontal standard error (RMS) of 0.137 m RMS, or 0.225 at 90% confidence.
