NATT - Numerical Analysis of Topographical Trends

Hotkey: N

Context menu: NATT


This image shows the result of the pointwise trend analysis as numerically. The method is described in detail here.

Each measured point shows 2 number. The upper number is the statistical start value, the lower value is the end value. The numbers are color coded

Green is significant improvement (dark green p>90%, light green p>95% )

Red is significant deterioration (dark red p>90%, light red p>95%)

Turquoise is not-significant improvement (p<90%)

Brown is not-significant deterioration (p<90%)


CONCLUSION: This image type visualizes the areas of change by the color. The numbers provide exact information about the prior damage and the amount of change. Color informs about the significance of change. Therewith, this image allows an exact evaluation of the pointwise trend. An overall evaluation is practically impossible with 100-200 numbers, therefore the SuperTrend image or GATT should be consulted as well.


Note: The colors in this help page can deviate from the program for technical reasons
