A plugin for the Rasterio CLI that exports a raster dataset to the MBTiles (version 1.3) format. Features include automatic reprojection and concurrent tile generation.
Usage: rio mbtiles [OPTIONS] INPUT [OUTPUT]
Export a dataset to MBTiles (version 1.3) in a SQLite file.
The input dataset may have any coordinate reference system. It must have
at least three bands, which will be become the red, blue, and green bands
of the output image tiles.
An optional fourth alpha band may be copied to the output tiles by using
the --rgba option in combination with the PNG or WEBP formats. This option
requires that the input dataset has at least 4 bands.
The default quality for JPEG and WEBP output (possible range: 10-100) is
75. This value can be changed with the use of the QUALITY creation option,
e.g. `--co QUALITY=90`. The default zlib compression level for PNG output
(possible range: 1-9) is 6. This value can be changed like `--co
ZLEVEL=8`. Lossless WEBP can be chosen with `--co LOSSLESS=TRUE`.
If no zoom levels are specified, the defaults are the zoom levels nearest
to the one at which one tile may contain the entire source dataset.
If a title or description for the output file are not provided, they will
be taken from the input dataset's filename.
This command is suited for small to medium (~1 GB) sized sources.
Python package: rio-mbtiles (https://github.com/mapbox/rio-mbtiles).
Options:
-o, --output PATH Path to output file (optional alternative to
a positional arg).
--append / --overwrite Append tiles to an existing file or
overwrite.
--title TEXT MBTiles dataset title.
--description TEXT MBTiles dataset description.
--overlay Export as an overlay (the default).
--baselayer Export as a base layer.
-f, --format [JPEG|PNG|WEBP] Tile image format.
--tile-size INTEGER Width and height of individual square tiles
to create. [default: 256]
--zoom-levels MIN..MAX A min...max range of export zoom levels. The
default zoom level is the one at which the
dataset is contained within a single tile.
--image-dump PATH A directory into which image tiles will be
optionally dumped.
-j INTEGER Number of workers (default: number of
computer's processors).
--src-nodata FLOAT Manually override source nodata
--dst-nodata FLOAT Manually override destination nodata
--resampling [nearest|bilinear|cubic|cubic_spline|lanczos|average|mode|gauss|max|min|med|q1|q3|rms]
Resampling method to use. [default:
nearest]
--version Show the version and exit.
--rgba Select RGBA output. For PNG or WEBP only.
--implementation [cf|mp] Concurrency implementation. Use
concurrent.futures (cf) or multiprocessing
(mp).
-#, --progress-bar Display progress bar.
--covers TEXT Restrict mbtiles output to cover a quadkey
--cutline PATH Path to a GeoJSON FeatureCollection to be
used as a cutline. Only source pixels within
the cutline features will be exported.
--oo NAME=VALUE Format driver-specific options to be used
when accessing the input dataset. See the
GDAL format driver documentation for more
information.
--co, --profile NAME=VALUE Driver specific creation options. See the
documentation for the selected output driver
for more information.
--wo NAME=VALUE See the GDAL warp options documentation for
more information.
--exclude-empty-tiles / --include-empty-tiles
Whether to exclude or include empty tiles
from the output.
--help Show this message and exit.The rio-mbtiles command is suited for small to medium (~1 GB) raster sources. On a MacBook Air, the 1:10M scale Natural Earth raster (a 21,600 x 10,800 pixel, 700 MB TIFF) exports to MBTiles (levels 1 through 5) in 45 seconds.
