RANDOM FIELD
|
|
============
|
|
|
|
Description
|
|
-----------
|
|
This algorithm generates a random grid layer. You can set the geographical position (referring to the south-west corner of the grid) and the statistical method used for the calculation of the cell values.
|
|
Two statistical methods are available:
|
|
- uniform
|
|
- gaussian
|
|
Parameters
|
|
----------
|
|
|
|
- ``Width (Cells)[Number]``:x-axis cell number
|
|
- ``Height (Cells)[Number]``:y-axis cell number
|
|
- ``Cellsize[Number]``: size of the cell (in meters)
|
|
- ``West[Number]``:west coordinate of the bottom-left corner of the grid
|
|
- ``South[Number]``:south coordinate of the bottom-left corner of the grid
|
|
- ``Method[Selection]``:statistical method used for the calculation
|
|
- ``Range Min[Number]``:minimum value of the cell (range)
|
|
- ``Range Max[Number]``:maximum value of the cell (range)
|
|
- ``Arithmetic Mean[Number]``:mean of all the cell values
|
|
- ``Standard Deviation[Number]``:standard deviation of all the cell values
|
|
|
|
Outputs
|
|
-------
|
|
|
|
- ``Random Field[Raster]``: the resulting grid
