Simple web pages with viewers based on OpenLayers and Leaflet are generated as well - so anybody can comfortably explore your maps on-line and you do not need to install or configure any special software (like MapServer) and the map displays very fast in the web browser. You only need to upload the generated di- rectory onto a web server. It generates PNG files by default, but other output formats can be se- lected (JPEG, WEBP, GTiff, etc.). Note that not all formats support non-Byte data types. JPEG and WEBP only support Byte. PNG supports Byte and UInt16. GeoTiff can support all data types. It can also use a tiling scheme fully adapted to the input raster, in terms of origin and resolution, when using the raster tiling scheme. In that scheme, tiles at the maximum zoom level will have the same resolu- tion as the raster. Standard options -i, --input <INPUT> Input raster dataset [required] -o, --output <OUTPUT> Output directory [required] The directory will be created if it does not exist, but its par- ent directory must exist. -f, --of, --format, --output-format <OUTPUT-FORMAT> Which output raster format to use. Allowed values may be given by gdal --formats | grep raster | grep rw | sort Defaults to PNG. --co <NAME>=<VALUE> Many formats have one or more optional creation options that can be used to control particulars about the file created. For in- stance, the GeoTIFF driver supports creation options to control compression, and whether the file should be tiled. May be repeated. The creation options available vary by format driver, and some simple formats have no creation options at all. A list of op- tions supported for a format can be listed with the --formats command line option but the documentation for the format is the definitive source of information on driver creation options. See Raster drivers format specific documentation for legal cre- ation options for each format. --tiling-scheme <TILING-SCHEME> Tile cutting scheme. Defaults to WebMercatorQuad (also known as Google Maps compatible). The following base profiles are available: • raster: CRS = CRS of raster, tile size = 256 pixels, raster coverage at all zoom levels. • WebMercatorQuad: CRS = EPSG:3857 ("WGS 84 / Pseudo-Mercator"), tile size: 256 pixels, whole world coverage at zoom level 0, one single tile at zoom level 0. • WorldCRS84Quad: CRS = EPSG:4326 ("WGS 84"), tile size: 256 pixels, whole world coverage at zoom level 0, two side-by-side tiles at zoom level 0 • WorldMercatorWGS84Quad: CRS = EPSG:3395 ("WGS 84 / World Mer- cator"), tile size: 256 pixels, whole world coverage at zoom level 0, one single tile at zoom level 0. This can be seen as a variant of WebMercatorQuad except that it is fully conformal on the WGS84 ellipsoid. • GoogleCRS84Quad: CRS = EPSG:4326 ("WGS 84"), tile size: 256 pixels, whole world coverage at zoom level 0, one single tile at zoom level 0 whose first and last 64 lines are blank (the top origin of the tile is a pseudo latitude of 180 degree, and its bottom -180 degree). • PseudoTMS_GlobalMercator: CRS = EPSG:3857 ("WGS 84 / Pseudo-Mercator"), tile size: 256 pixels, whole world coverage at zoom level 0, 2x2 tiles at zoom level 0. This is equivalent to WebMercatorQuad, but with the zoom level shifted by one. • LINZAntarticaMapTileGrid: LINZ Antarctic Map Tile Grid (Ross Sea Region). See tms_LINZAntarticaMapTileGrid.json • APSTILE: Alaska Polar Stereographic-based tiled coordinate reference system for the Arctic region. See - tms_MapML_APSTILE.json • CBMTILE: Lambert Conformal Conic-based tiled coordinate refer- ence system for Canada. See tms_MapML_CBMTILE.json • NZTM2000: LINZ NZTM2000 Map Tile Grid. See tms_NZTM2000.json Additional tiling schemes are discovered from tms_XXXX.json files placed in the GDAL data directory. --min-zoom <MIN-ZOOM> Minimum zoom level to generate. If not specified, equal to --max-zoom. --max-zoom <MAX-ZOOM> Maximum zoom level to generate. If not specified, this will be determined by comparing the resolution of the input dataset with the closest resolution in the list of tile matrix of the tile matrix set. --min-x <MIN-X> Minimum tile X coordinate, at maximum zoom level. Can be set to restrict the tiling process. --min-y <MIN-Y> Minimum tile Y coordinate, at maximum zoom level. Can be set to restrict the tiling process. --max-x <MAX-X> Maximum tile X coordinate, at maximum zoom level. Can be set to restrict the tiling process. --max-y <MAX-Y> Maximum tile Y coordinate, at maximum zoom level. Can be set to restrict the tiling process. --no-intersection-ok Whether the dataset extent not intersecting the tile matrix is only a warning. Otherwise, by default, an error will be emitted if that occurs. -r, --resampling nearest|bilinear|cubic|cubicspline|lanczos|aver- age|rms|mode|min|max|med|q1|q3|sum Resampling method used to generate maximum zoom level, and also lower zoom levels if --overview-resampling is not specified. Defaults to cubic. --overview-resampling nearest|bilinear|cubic|cubicspline|lanczos|aver- age|rms|mode|min|max|med|q1|q3|sum Resampling method used to generate zoom levels lower than the maximum zoom level. Defaults to the value of --resampling is not specified. --convention xyz|tms Tile numbering convention: • xyz (default): from top, as in OGC Web Map Tiling Specifica- tion (WMTS) • tms: from bottom, as in OSGeo Tile Map Service (TMS) Specifi- cation. --tile-size <PIXELS> Width and height of a tile, in pixels. Default is 256 for de- fault tiling schemes. Setting it to a higher value enables gen- erating higher DPI tile sets. --add-alpha Whether to force adding an alpha channel. An alpha channel is added by default, unless the source dataset has a nodata value and the output format supports it. --no-alpha Disable the creation of an alpha channel. --dstnodata <DSTNODATA> Destination nodata value. --skip-blank Do not generate fully blank/transparent tiles. --metadata <KEY>=<VALUE> Add metadata item to output tiles [may be repeated] --copy-src-metadata Whether to copy metadata from source dataset into output tiles. --aux-xml Generate .aux.xml sidecar files when needed --kml Generate Google Earth SuperOverlay metadata. Not compatible with tiling schemes with non-power-of-two zoom levels. --resume Generate only missing files. Can be used when interrupting a previous run to restart it. -j, --num-threads <value> Number of jobs to run at once. Default: number of CPUs de- tected. Advanced Resampling Options --excluded-values=<EXCLUDED-VALUES> Comma-separated tuple of values (thus typically "R,G,B"), that are ignored as contributing source pixels during resampling. The number of values in the tuple must be the same as the number of bands, excluding the alpha band. Several tuples of excluded values may be specified using the "(R1,G1,B2),(R2,G2,B2)" syn- tax. Only taken into account for average resampling. This con- cept is a bit similar to nodata/alpha, but the main difference is that pixels matching one of the excluded value tuples are still considered as valid, when determining the target pixel va- lidity/density. Added in version 3.11.1. --excluded-values-pct-threshold=<EXCLUDED-VALUES-PCT-THRESHOLD> Minimum percentage of source pixels that must be set at one of the --excluded-values to cause the excluded value, that is in majority among source pixels, to be used as the target pixel value. Default value is 50(%) Added in version 3.11.1. --nodata-values-pct-threshold=<NODATA-VALUES-PCT-THRESHOLD> Minimum percentage of source pixels that must be at nodata (or alpha=0 or any other way to express transparent pixel) to cause the target pixel value to be transparent. Default value is 100 (%), which means that a target pixel is transparent only if all contributing source pixels are transparent. Only taken into ac- count for average resampling. Added in version 3.11.1. Publication Options --webviewer none|all|leaflet|openlayers|mapml Web viewer to generate. Defaults to all. --url URL address where the generated tiles are going to be published. --title <TITLE> Title of the map. --copyright <COPYRIGHT> Copyright for the map. MapML options MapML webviewer can only be generated if --convention is set to the de- fault value xyz. The following profiles are supported: • WebMercatorQuad: mapped to OSMTILE MapML tiling scheme • GoogleCRS84Quad: mapped to WGS84 MapML tiling scheme • APSTILE: from the tms_MapML_APSTILE.json data file • CBMTILE: from the tms_MapML_CBMTILE.json data file The generated MapML file in the output directory is mapml.mapl Available options are: --mapml-template <filename> Filename of a template mapml file where variables will be sub- stituted. If not specified, the generic template_tiles.mapml file from GDAL data resources will be used The --url option is also used to substitute ${URL} in the template MapML file.
