Introduction

This enhancement to the gdal2tiles.py script includes the following additional features:

  • Parallel processing, to use all available machine cores when generating tiles. This speeds up tile creation considerably.
  • Support for both the TMS and XYZ tile cache formats. Use the -o flag to choose; XYZ is the default format.
  • Support for both PNG and JPEG tile outputs. Use the -f flag to choose; PNG is the default format.

Install

# #python3 -m ensurepip # install from local directory pip install . # Successfully installed gdal2tilesp.py-3.14.15926

Docker

The project roblabs/gdal-geopdf makes use of this Python script in a Dockerfile.

Command Line

Run gdal2tilesp.py --help to check all the command-line parameters of the script.

Usage: gdal2tilesp.py [options] input_file(s) [output] Options: --version show program's version number and exit  -h, --help show this help message and exit  -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,cubicsp  line,lanczos,antialias) - default 'average'  -s SRS, --s_srs=SRS The spatial reference system used for the source input  data  -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  --processes=PROCESSES  Number of concurrent processes (defaults to the number  of cores in the system)  -v, --verbose Print status messages to stdout   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,index,metadata,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  http://code.google.com/apis/maps/signup.html  -y YAHOOKEY, --yahookey=YAHOOKEY  Yahoo Application ID from  http://developer.yahoo.com/wsregapp/   Config options:  Options for config parameters   -x, --auxfiles Generate aux.xml files.  -f OUTPUT_FORMAT, --format=OUTPUT_FORMAT  Image format for output tiles. Just WEBP, PNG and JPEG  allowed. PNG is selected by default  -o OUTPUT_CACHE, --output=OUTPUT_CACHE  Format for output cache. Values allowed are tms and  xyz, being xyz the default value

Notes

  • Generates tilesjson in the file index.html, which then is consumed by KlokanTech tileview.
    • tileview further generates Leaflet, OpenLayers 2 & 3, Google Maps, WebGL, OL3-Cesium, Mapbox JS, and ArcGIS for JavaScript.
  • Generates Leaflet layer for use with the XYZ default format. Where the tms parameter is set to false
  • Generates metatdata.json which is interpreted by mb-util for use with mbtiles.
var lyr = L.tileLayer('./{z}/{x}/{y}.png', {tms: false, opacity: 1.0, attribution: ""}); 

Caveats

  • The epsg::900913 projection code is not supported, use epsg:3857 to generate a tile set in web mercator projection.
