 <h2>DESCRIPTION</h2>
 
-<em>r.cell.area</em> uses the current computational region to compute the area of each raster cell. It can do so on a projected coordinate system or on a geographic coordinate system; the latter is accomplished via the latitude of the cell's midpoint.
+<em>r.cell.area</em> uses the current computational region to compute the area of each raster cell. It can do so on a projected coordinate system or on a geographic coordinate system; the latter is accomplished via the latitude of the cell's midpoint. This approximation can generate ~1% error with coarse lat/lon cells near the poles.
