@chambbj thanks for the summary re: ground filters.
"First the outlier filter merely classifies outliers with a Classification value of 7."
Should be "First the outlier filter merely processes outliers with a Classification value of 7", yes? Because the points have already been classified, and outlier is actively removing points not just adding new attribute values?
example syntax in pipeline.json for writers.gdal is broken. I get PDAL: writers.gdal: Unexpected argument 'output_format'
using pdal 1.6.0 (git-version: Release)

@maphew this should work for the writers.gdal:
        "type":"writers.gdal",
        "filename":"myfilename.tif",
        "resolution":1.0,
        "output_type":"idw",
        "nodata":-9999,
        "window_size":2,
        "gdalopts":"COMPRESS=DEFLATE,TILED=YES,PREDICTOR=3"
the argument is output_type
