Destripe Raster Data

Destripe Raster Data

Use Destripe data to remove periodic scan line striping in image data. This type of striping is often seen in Landsat MSS data (every 6th line) and less commonly, in Landsat TM data (every 16th line). When destriping the data, ENVI calculates the mean of every nth line and normalizes each line to its respective mean. In order for destriping to function properly, the data must be in the acquired format (horizontal strips) and cannot be rotated or georeferenced.

  1. From the Toolbox, select Raster Management > Destripe.
  2. Select an input file and perform optional spatial and spectral subsetting, then click OK. The Destriping Parameters dialog appears.
  3. Enter the number of detectors in the Number of Detectors field. The number of detectors is the periodicity of the striping (for example, for Landsat MSS, the value would be 6). If the file type has been set in the header, the default is set automatically.
  4. Select output to File or Memory.
  5. Click OK.
