R Documentation

HuntLS Program HuntLS reads an "outlier" raster created by program Align. The "outlier" k values indicate the number of interquartile ranges (q3-q1) a DoD de (delta elevation) value falls outside of the interquartile range: k = (de-q1)/(q3-a1) if k is less than q1 and k = (de-q3)/(q3-q1) if k is greater than q3. Values of de between q1 and q3 are given k values of zero. HuntLS associates k patches with field-mapped landslide locations surveyed for the Post Mortem (Stewart et al., 2013) study.

Description

HuntLS Program HuntLS reads an "outlier" raster created by program Align. The "outlier" k values indicate the number of interquartile ranges (q3-q1) a DoD de (delta elevation) value falls outside of the interquartile range: k = (de-q1)/(q3-a1) if k is less than q1 and k = (de-q3)/(q3-q1) if k is greater than q3. Values of de between q1 and q3 are given k values of zero. HuntLS associates k patches with field-mapped landslide locations surveyed for the Post Mortem (Stewart et al., 2013) study.

`IDfield`	Character: LSpnts attributes-table field name for record ID.
`Radius`	Numeric (dbl): Search radius in meters for matching landslide points to k-value patches.
`AspectLength`	Numeric (dbl): Length in meters to calculate aspect.
