Add Topographic Attributes High

This tool add a number of topographic attributes to the input bathymetric high feature class.

The following attributes are calculated from the bathymetry and slope-gradient rasters to describe the topographic properties of each bathymetric high feature.

  1. minDepth: the minimum water depth within the feature polygon

  2. maxDepth: the maximum water depth within the feature polygon

  3. depthRange: the difference in water depth within the feature polygon, which is calculated by equation (1)

    (1)\[(maxDepth - minDepth)\]

  4. meanDepth: the mean water depth within the feature polygon

  5. stdDepth: the standard deviation of the water depths within the feature polygon

  6. minGradient: the minimum slope-gradient within the feature polygon

  7. maxGradient: the maximum slope-gradient within the feature polygon

  8. gradientRange: the difference in slope-gradient within the feature polygon, which is calculated by equation (2)

    (2)\[(maxGradient - minGradient)\]

  9. meanGradient: the mean slope-gradient within the feature polygon

  10. stdGradient: the standard deviation of the slope-gradients within the feature polygon
