The ''Fill Nodata'' tool creates a new raster by filling in small areas or gaps in a raster where no elevation data exists. The command will interpolate an elevation to raster cells that are classified as “NODATA.” The elevation for a NODATA cell is determined by interpolation based on the search radius specified. The command is intended to correct single isolated raster points or a single row/column, and is not intended to create data for large regions of NODATA cells, especially regions on the border of the raster. | |||

The Fill Nodata tool creates a new raster by filling in small areas or gaps in a raster where no elevation data exists. The command will interpolate an elevation to raster cells that are classified as “NODATA.” The elevation for a NODATA cell is determined by interpolation based on the search radius specified. The command is intended to correct single isolated raster points or a single row/column, and is not intended to create data for large regions of NODATA cells, especially regions on the border of the raster.
Input parameters
Input raster – The source raster containing the NODATA values. Maximum distance (in pixels) to interpolate – Enter a distance used to search out values to interpolate from, to fill in the NODATA values. The default is 100 pixels. The number of 3x3 average filter smoothing iterations to run – Enter the number of smoothing iterations to run after the interpolation has been calculated. The default is 0 runs.
Output parameters
Output raster – Enter a name for the new raster.
