The information to complete the cells without data is taken from the surrounding cells using interpolation methods.&#10;&#10;The folowing example shows a layer with elevation values that was created by rasterizing a vector layer with contour lines. Only cells under those contour lines contain elevation values, while the remaining ones have no-data values.&#10;&#10;By running the "void filling" algorithm, a DEM with values in all of its cells is obtained.' description="Description" type="0">
