landroughness

Surface height standard deviation for land

    Description

    example

    hgtsd = landroughness(landtype) returns the standard deviation of the surface height for the specified land type.

    [hgtsd,beta0,vegtype] = landroughness(landtype) in addition to hgtsd returns:

    • beta0 — the slope of the land type.

    • vegtype — the vegetation type.

    Examples

    collapse all

    Obtain the standard deviation of the surface height for an urban land.

    hgtsd = landroughness('Urban')
    hgtsd = 10
    

    Input Arguments

    collapse all

    Surface land type, specified as a string of one of the allowed land types.

    Example: landtype = "Urban"

    Output Arguments

    collapse all

    Standard deviation of the surface height, returned as a scalar in meters.

    Slope of the land type β0, returned as a scalar in degrees.

    The vegetation type is a character array determined by the landtype input.
