COMMAND LINE OPTIONS

Flag:

-c

Values are taken from category lables of the covering-layer, instead of covering-layer itself.

Parameters:

base

Base raster map

cover

Cover raster map

method

Statistical method

Options: distribution, average, mode, median, avedev, stddev, variance, skewness, kurtosis, min, max, sum

output

Name of the new layer (not when using 'distribution')

Setting the -c flag the category lables of the covering raster layer will be used. This is nice to avoid the GRASS limitation to interger in raster maps because using category values floating point numbers can be stored.

The output-layer is a reclassified version of the base-layer with identical category values. The results of the calculations are stored in the category labels of the output-layer.

The described output is valid for all calculations with exception of distribution. Here the output is given to stdout. A file name eventually specified will be ignored. The result will be a table with three columns. In the 1. column are the category values of the base-layer (a), in the 2. column the associated value of the cover-Layers (b) and in the 3. column the percentage of b from a. Example:

                                 1   124  23
                                 1   201  47
                                 1   273  30
                                 2   101  5
                                 2   152  16
                                 2   167  60
                                 2   187  19
                                      .
                                      .
                                      .
