DESCRIPTION

The r.in.mb module will load and grid Multibeam data into a new raster map via the mbio library. The user may choose from a variety of statistical methods in creating the new raster. A number of mutibeam specific options are also available.

Available statistics for populating the raster are:

n number of points in cell

min minimum value of points in cell

max maximum value of points in cell

range range of points in cell

sum sum of points in cell

mean average value of points in cell

stddev standard deviation of points in cell

variance variance of points in cell

coeff_var coefficient of variance of points in cell

median median value of points in cell

percentile p^th percentile of points in cell

skewness skewness of points in cell

trimmean trimmed mean of points in cell

Variance and derivatives use the biased estimator (n). [subject to change]
Coefficient of variance is given in percentage and defined as (stddev/mean)*100.
