Horizontal Accuracy notes:  
+
----
−
1. The random horizontal error is the random circular error at point (reported at 90% confidence).  
+
 
−
2. The Relative Horizontal Accuracy (point-to-point) between points is calculated at the 90% confidence interval.  
+
 
−
3. The relative (point-to-point) horizontal accuracy is based on a distance (“D”) which is determined by the size of a standard DGED dataset at a given DGED Level. “D” is defined as the maximum radial distance between any two points in the said tile. The relative error is expected to vary as a function of distance between points, and its value ranges from R0 for points within one pointspacing to the table value for points at distance “D”.  
+
 
−
4. The absolute horizontal accuracy is a goal value, but not a requirement. Although not required to meet a threshold, the Absolute Horizontal Accuracy should be reported in the metadata and is measured at the 90% confidence interval as a CE90.  
+
<table class=MsoNormalTable border=1 cellspacing=0 cellpadding=0 width=813
−
5. Relative Horizontal Accuracy and random horizontal error may be difficult to assess in the coarse datasets. In these datasets, very large targets (which may not be available) would be required for such assessment. Therefore, the relative horizontal accuracy may not be evaluated for Levels 0 to 5.

Through a process referred to as "rating" an image, the NIIRS is used by imagery analysts to assign a number which indicates the interpretability of a given image. The NIIRS concept provides a means to directly relate the quality of an image to the interpretation tasks for which it may be used. Although the NIIRS has been primarily applied in the evaluation of aerial imagery, it provides a systematic approach to measuring the quality of photographic or digital imagery, the performance of image capture devices, and the effects of image processing algorithms. </span></p>

Definition

absolute horizontal accuracy of the data’s coordinates, expressed in terms of circular error at 90 % probability given that a bias is present

6

Description

A comparison of the data (source) and the control (reference) is calculated in the following manner:

1. Calculate the absolute error in the horizontal dimension at each point:

Δ H i = ( source X i − reference X i ) 2 + ( source Y i − reference Y i ) 2 for i = 1…N

2. Calculate the mean horizontal error:

μ H = ( ∑ Δ H i ) N

3. Calculate the standard deviation of the horizontal errors:

σ H = ∑ ( Δ H i − μ H ) 2 ( N − 1 )

4. Calculate the ratio of the absolute value of the mean error to the standard deviation:

ratio = | μ H | / σ H

5. If ratio > 1 , 4 , then k = 1 , 281   5

6. If ratio ≤ 1,4, then calculate k, the ratio of the mean to the standard deviation, using a cubic polynomial fit through the tabular values as defined in the CRC Handbook of Tables for Probability and Statistics [ 20 ]

k = 1 , 643   5 − ( 0 , 999   556 × ratio ) + ( 0 , 923   237 × ratio 2 ) − ( 0 , 282   533 × ratio 3 )

7. Compute CE90 for the source:

CE90 source = | μ H | + ( k × σ H )

8. Compute absolute CE90:

CE90 abs = CE90 reference 2 + CE90 source 2

Definition

The aerial imaging community utilizes the National Imagery Interpretability Rating Scale (NIIRS) to define and measure the quality of images and performance of imaging systems. Through a process referred to as "rating" an image, the NIIRS is used by imagery analysts to assign a number which indicates the interpretability of a given image. The NIIRS concept provides a means to directly relate the quality of an image to the interpretation tasks for which it may be used. Although the NIIRS has been primarily applied in the evaluation of aerial imagery, it provides a systematic approach to measuring the quality of photographic or digital imagery, the performance of image capture devices, and the effects of image processing algorithms.
