ℹ️ If you came here from the original tutorial you will find the corresponding source code in the v1 branch: https://github.com/jimutt/tiles-to-tiff/tree/v1

The master branch has been updated with a small addition to offer a simple CLI.

tiles-to-tiff

Python script for converting XYZ raster tiles for slippy maps to a georeferenced TIFF image.

Prerequisites:

• Python & available GDAL installation

Usage:

tiles_to_tiff {tile_source} {lng_min} {lat_min} {lng_max} {lat_max} -o {output_directory} -z {zoom level}

Create georeferenced TIFF from online tileserver:

python tiles_to_tiff https://tileserver-url.com/{z}/{x}/{y}.png 21.49147 65.31016 21.5 65.31688 -o output -z 17

Use local tile source:

python tiles_to_tiff file:///Users/Bob/local-directory 21.49147 65.31016 21.5 65.31688 -o output -z 17

TMS Tiles

In the tile source there is the ability to use {-y} in the URL. In TMS, the origin of coordinates is the bottom left corner so the Y coordinate goes up.

CLI arguments:

• lng_min - Min longitude of bounding box
• lat_min - Min latitude of bounding box
• lng_max - Max longitude of bounding box
• lat_max - Max latitude of bounding box
• -z, --zoom - Tilesource zoom level, default 14
• -o, --output - Output directory, required
