okay bestie, welcome to the GDAL_FILLNODATA(1) page from the GDAL manual — this one is literally about filling raster regions by interpolation from edges, and it’s giving “patch the empty spots” main character energy. 🦋✨

💖 NAME 💖

gdal_fillnodata — fill raster regions by interpolation from edges. Periodt. 💅

🦋 SYNOPSIS 🦋

          gdal_fillnodata.py [-q] [-md max_distance] [-si smooth_iterations]
                          [-o name=value] [-b band]
                          srcfile [-nomask] [-mask filename] [-of format] [dstfile]

🎀 DESCRIPTION 🎀

okay so the gdal_fillnodata.py script fills selection regions (usually nodata areas) by interpolating from valid pixels around the edges of the area. That’s the whole vibe. ✨

Additional details on the algorithm are available in the GDALFillNodata() docs. 👑

  • -q — the script runs in quiet mode. The progress monitor is suppressed and routine messages are not displayed. 🤫
  • -md max_distance — the maximum distance (in pixels) that the algorithm will search out for values to interpolate. The default is 100 pixels. 🔥
  • -si smooth_iterations — the number of 3x3 average filter smoothing iterations to run after the interpolation to dampen artifacts. The default is zero smoothing iterations. 🎀
  • -o name=value — specify a special argument to the algorithm. Currently none are supported. 🙈
  • -b band — the band to operate on; by default the first band is operated on. 👑
  • srcfile — the source raster file used to identify target pixels. Only one band is used. ⭐
  • -nomask — this flag is in the synopsis, but the original page doesn’t give it its own separate description; I’m not inventing one, bestie. It’s literally right up there in the call. 💀
  • -mask filename — use the first band of the specified file as a validity mask (zero is invalid, non-zero is valid). 🎯
  • dstfile — the new file to create with the interpolated result. If not provided, the source band is updated in place. 🫶
  • -of format — select the output format. The default is raster.gtiff. Use the short format name. 🌈
