re open options could determine the
pixel values; not sure if any other drivers beside TileDB share this
characteristic.
Thanks for your input,

https://github.com/mapbox/rio-l8qa might be what you're looking for;
provides a python API and CLI for extracting arrays out of the Landsat QA
band, both the pre-Collection and collection format. It's at version 0.1 so
caveat emptor but could be useful. Let me know how it works for you.
Even,
Thanks for the fix, the workaround and the detailed explanation. I
knew there must be a reason for the strange threshold.

rious why it there appears to be a buffer size threshold, why it
only affects alpha bands and why only GDAL 2.x is affected. Before I
dig in, does anyone have any theories about what's going on here?
Thanks,

"equal" with regard to what? Number of features? Area of features?
File size? Some attribute field?

Stephen,
It'd be great to see local hydrologic slope in gdaldem.
I've seen a similar discrepancy between "field" slope and most
GIS-derived slopes. The local max hydrologic slope seems to correspond
much better to our perceived slope on the ground. The integrated slope
used in most GIS, however,
