A python library for generating map tiles inspired by gdal2tiles.py_ from GDAL_ project.

Dependancies

• GDAL_ development header files, sometimes available as libgdal-dev or libgdal-devel packages.

Installation

To install gdal2tiles library you can use pip:

.. code-block:: console

$ pip install gdal2tiles

Basic usage

.. code-block:: python

import gdal2tiles

gdal2tiles.generate_tiles('/path/to/input_file', '/path/to/output_dir/')

You can also pass various keyword as optional keyword arguments to generate_tiles() function. For example

.. code-block:: python

gdal2tiles.generate_tiles('input_file', 'output_dir/', nb_processes=2, zoom='7-9')

OR

.. code-block:: python

options = {'zoom': (7, 9), 'resume': True}
gdal2tiles.generate_tiles('input_file', 'output_dir/', **options)

In general

.. code-block:: python

gdal2tiles.generate_tiles(input_file, output_folder, **options)

Arguments: input_file (str): Path to input file.

``output_folder`` *(str)*: Path to output folder.

``options``: Tile generation options.

Options: profile (str): Tile cutting profile (mercator,geodetic,raster) - default 'mercator' (Google Maps compatible)

``resampling`` *(str)*: Resampling method (average,near,bilinear,cubic,cubicsp
    line,lanczos,antialias) - default 'average'

``s_srs``: The spatial reference system used for the source input data

``zoom``: Zoom levels to render; format: '[int min, int max]',
    'min-max' or 'int/str zoomlevel'.

``tile_size`` *(int)*: Size of tiles to render - default 256

``resume`` *(bool)*: Resume mode. Generate only missing files.

``srcnodata``: NODATA transparency value to assign to the input data

``tmscompatible`` *(bool)*: When using the geodetic profile, specifies the base
    resolution as 0.703125 or 2 tiles at zoom level 0.

``verbose`` *(bool)*: Print status messages to stdout

``kml`` *(bool)*: Generate KML for Google Earth - default for 'geodetic'
                profile and 'raster' in EPSG:4326. For a dataset with
                different projection use with caution!

``url`` *(str)*: URL address where the generated tiles are going to be published

``webviewer`` *(str)*: Web viewer to generate (all,google,openlayers,none) -
    default 'all'

``title`` *(str)*: Title of the map

``copyright`` *(str)*: Copyright for the map

``googlekey`` (str): Google Maps API key from
    http://code.google.com/apis/maps/signup.html

``bingkey`` *(str)*: Bing Maps API key from https://www.bingmapsportal.com/

``nb_processes`` *(int)*: Number of processes to use for tiling.
