<title>Description</title>
<para>Reprojects a raster in a known spatial reference system to another known spatial reference system using specified pixel warping algorithm.
Uses 'NearestNeighbor' if no algorithm is specified and maxerror percent of 0.125 if no maxerr is specified.</para>
<para>Algorithm options are: 'NearestNeighbor', 'Bilinear', 'Cubic', 'CubicSpline', and 'Lanczos'. Refer to: <ulink url="http://www.gdal.org/gdalwarp.html">GDAL Warp resampling methods</ulink> for more details.</para>
<para>Availability: 2.0.0 Requires GDAL 1.6.1+</para>
