- <h2>DESCRIPTION</h2>
- <em>r.reclass.area</em> reclasses a raster map greater or
- less than a user specified area size (in hectares).
- <p>
- If the <b>-c</b> flag is used, <em>r.reclass.area</em> will skip the
- creation of a clumped raster and assume that the input raster is
- already clumped.
- <h2>EXAMPLES</h2>
- In this example, the ZIP code map in the North Carolina sample dataset
- location is filtered for large areas (removing smaller areas from the
- map).
- <div class="code"><pre>
- g.region raster=zipcodes -p
- r.report zipcodes unit=h
- </pre></div>
- Extract only areas greater than 2000 ha, NULL otherwise:
- <div class="code"><pre>
- r.reclass.area input=zipcodes output=zipcodes_larger2000ha mode=greater value=2000
-
- r.report zipcodes_larger2000ha unit=h
- </pre></div>
- <div align="center" style="margin: 10px">
- <img src="zipcodes_larger2000ha.png" width="800px" height="264px"><br>
- <i>Figure: r.reclass.area method=reclass</i>
- </div>
- In this example, the ZIP code map in the North Carolina sample dataset
- location is filtered for smaller areas which are substituted with the
- value of the respective adjacent area with largest shared
- boundary. Reclass by substitutional removing of areas minor of 1000 ha:
- <div class="code"><pre>
- r.reclass.area input=zipcodes output=zipcodes_minor1000ha mode=lesser value=1000 method=rmarea
- </pre></div>
- <div align="center" style="margin: 10px">
- <img src="zipcodes_minor1000ha.png" width="800px" height="264px"><br>
- <i>Figure: r.reclass.area method=rmarea</i>
- </div>
