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 0.081m RMS, or 0.133 at 90% confidence.
