untiler
Utility to take a directory of {z}/{x}/{y}.(jpg|png) tiles, and stitch into a scenetiff (tif w/ exact merc tile bounds). Future versions will support fast indexed reading directly from tar archives.

streamdir
Given a directory of tiles + a read template, mosaic into tifs at a lower parent "composite" zoom extent
untiler streamdir [OPTIONS] INPUT_DIR OUTPUT_DIR
-c, --compositezoom INTEGER Tile size to mosaic into [default=13]
-z, --maxzoom INTEGER Force a maxzom [default=max in each
compositezoom area]
-l, --logdir TEXT Location for log files [default=None]
-t, --readtemplate TEXT File path template
[default='jpg/{z}/{x}/{y}.jpg']
-s, --scenetemplate TEXT Template for output scenetif filenames
[default='{z}-{x}-{y}-tile.tif']
-w, --workers INTEGER Number of workers in the processing pool
[default=4]
-x, --no-fill Don't fill in with lower zooms
-r, --tile-resolution Size of input tiles for eg 256, 512 etc
--help Show this message and exit.
streammbtiles
Mosaic an mbtiles into tifs of "composite" zoom extent
untiler streammbtiles [OPTIONS] MBTILES OUTPUT_DIR
Options:
--co NAME=VALUE Driver specific creation options.See the
documentation for the selected output driver
for more information.
-c, --compositezoom INTEGER Tile size to mosaic into [default=13]
-z, --maxzoom INTEGER Force a maxzom [default=max in each
compositezoom area]
-s, --scenetemplate TEXT Template for output scenetif filenames
[default='{z}-{x}-{y}-tile.tif']
-w, --workers INTEGER Number of workers in the processing pool

inspectdir
Stream [x, y, z]s of a directory
untiler inspectdir [OPTIONS] INPUT_DIR
Options:
-z, --zoom INTEGER Zoom to inspect [default = all]
--help Show this message and exit.
Outputs a line-delimited stream of tile [x, y, z]s; useful to pipe into mercantile shapes to visualize geometry:
untiler inspectdir <dir> -z 19 | mercantile shapes | fio collect | geojsonio
