<h1 class='module'>Reclassify Grid Values</h1>
|
|
<div class='author'>Copyrights (c) 2005 by Volker Wichmann</div>
|
|
<div class='description'>The module can be used to reclassify the values of a grid. It provides three different options: (a) reclassification of single values, (b) reclassification of a range of values and (c) reclassification of value ranges specified in a lookup table. In addition to theses methods, two special cases (No-Data values and values not included in the reclassification setup) are supported. In mode (a) and (b) the 'No-Data option' is evaluated before the method settings, in mode (c) the option is evaluated only if the No-Data value ins't included in the lookup table. The 'other values' option is always evaluated after checking the method settings. </div>
