gdal2tiles.py
generates web map tiles from rasters
TLDR
Generate tiles from image
$ gdal2tiles.py [input.tif] [output_dir]
Specify zoom levels$ gdal2tiles.py -z [5-18] [input.tif] [output_dir]
Generate for Leaflet$ gdal2tiles.py -w leaflet [input.tif] [output_dir]
Use multiple processes$ gdal2tiles.py --processes=[4] [input.tif] [output_dir]
Specify tile format$ gdal2tiles.py --tileformat=[png] [input.tif] [output_dir]
SYNOPSIS
gdal2tiles.py [options] input outputdirectory_
DESCRIPTION
gdal2tiles.py generates map tiles from georeferenced raster images. It creates tile pyramids compatible with web mapping libraries like Leaflet and OpenLayers.The tool produces XYZ or TMS tile structures with optional HTML viewer pages. It handles large images by generating multiple zoom levels with appropriate resampling.gdal2tiles.py enables serving large geospatial imagery as web map tiles.
PARAMETERS
INPUT
Input raster file (GeoTIFF, etc.).OUTPUTDIRECTORY_

CAVEATS
Large images need significant disk space. Processing time scales with zoom levels. Source must be georeferenced.
HISTORY
gdal2tiles.py is part of GDAL (Geospatial Data Abstraction Library), providing tile generation for web mapping from geospatial raster data.
