gdal2tiles - Generates directory with TMS tiles, KMLs and simple web viewers.

SYNOPSIS [-p profile] [-r resampling] [-s srs] [-z zoom]

              [-w webviewer] [-t title] [-c copyright]
              [--processes=NB_PROCESSES] [--xyz]
              [-g googlekey] [-b bingkey] input_file [output_dir]


This utility generates a directory with small tiles and metadata, following the OSGeo Tile Map Service Specification. Simple web pages with viewers based on Google Maps, 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 directory onto a web server.

GDAL2Tiles also creates the necessary metadata for Google Earth (KML SuperOverlay), in case the supplied map uses EPSG:4326 projection.

World files and embedded georeferencing is used during tile generation, but you can publish a picture without proper georeferencing too.


Inputs with non-Byte data type (i.e. Int16, UInt16,...) will be clamped to the Byte data type, causing wrong results. To awoid this it is necessary to rescale input to the Byte data type using gdal_translate utility.

-p <PROFILE>, --profile=<PROFILE>
Tile cutting profile (mercator, geodetic, raster) - default 'mercator' (Google Maps compatible).

-r <RESAMPLING>, --resampling=<RESAMPLING>
Resampling method (average, near, bilinear, cubic, cubicspline, lanczos, antialias, mode, max, min, med, q1, q3) - default 'average'.

-s <SRS>, --s_srs=<SRS>
The spatial reference system used for the source input data.

Generate XYZ tiles (OSM Slippy Map standard) instead of TSM

New in version 3.1.

-z <ZOOM>, --zoom=<ZOOM>
Zoom levels to render (format:'2-5' or '10').

-e, --resume
Resume mode. Generate only missing files.

-a <NODATA>, --srcnodata=<NODATA>
NODATA transparency value to assign to the input data.

-v, --verbose
Generate verbose output of tile generation.

-q, --quiet
Disable messages and status to stdout

New in version 2.1.

Number of processes to use for tiling.

New in version 2.3.

Pixel size of the tiles.

New in version 3.1.

-h, --help
Show help message and exit.

Show program's version number and exit.

KML (Google Earth) options

Options for generated Google Earth SuperOverlay metadata
-k, --force-kml
Generate KML for Google Earth - default for 'geodetic' profile and 'raster' in EPSG:4326. For a dataset with different projection use with caution!

-n, --no-kml
Avoid automatic generation of KML files for EPSG:4326.

-u <URL>, --url=<URL>
URL address where the generated tiles are going to be published.

Web viewer options

Options for generated HTML viewers a la Google Maps
-w <WEBVIEWER>, --webviewer=<WEBVIEWER>
Web viewer to generate (all, google, openlayers, leaflet, none) - default 'all'.

-t <TITLE>, --title=<TITLE>
Title of the map.

-c <COPYRIGHT>, --copyright=<COPYRIGHT>
Copyright for the map.

-g <GOOGLEKEY>, --googlekey=<GOOGLEKEY>
Google Maps API key from

-b <BINGKEY>, --bingkey=<BINGKEY>
Bing Maps API key from

NOTE: is a Python script that needs to be run against Python GDAL binding.


Basic example: --zoom=2-5 input.tif output_folder
