tms2geotiff

Download tiles from Tile Map Server (online maps) and make a large image.

If output is TIFF, it can write to a GeoTIFF image. Otherwise, it will save to a normal image with a World File for georeferencing (in EPSG:3857).

• Dependencies: Pillow, requests/httpx.
• Optional dependencies:
  • GDAL, numpy: for writing BigTIFF (>4GB GeoTIFF)
  • tqdm: progress bar

It can save the tiles directly as a MBTiles file now. The big image file is not required to generate.

GUI: Directly run python3 tms2geotiff.py to open a GUI window.

usage: tms2geotiff.py [-h] [-s URL] [-f LAT,LON] [-t LAT,LON] [-e min_lon,min_lat,max_lon,max_lat] [-z ZOOM]
                      [-m MBTILES] [-g]
                      [output]

Merge TMS tiles to a big image.

positional arguments:
  output                output image file (can be omitted)

options:
  -h, --help            show this help message and exit
  -s URL, --source URL  TMS server url (default is OpenStreetMap: https://tile.openstreetmap.org/{z}/{x}/{y}.png)
  -f LAT,LON, --from LAT,LON
                        one corner
  -t LAT,LON, --to LAT,LON
                        the other corner
  -e min_lon,min_lat,max_lon,max_lat, --extent min_lon,min_lat,max_lon,max_lat
                        extent in one string (use either -e, or -f and -t)
  -z ZOOM, --zoom ZOOM  zoom level
  -m MBTILES, --mbtiles MBTILES
                        save MBTiles file
  -g, --gui             show GUI

If no parameters are specified, it will open the GUI.

For example,

python3 tms2geotiff.py -s https://tile.openstreetmap.org/{z}/{x}/{y}.png -f 45.699,127 -t 30,148.492 -z 6 output.tiff

downloads a map of Japan.

If the coordinates are negative, use --from=-12.34,56.78 --to=-13.45,57.89

tmssplit

Split a large GeoTIFF image into tiles for a Tile Map Server.

Dependencies: GDAL, Pillow, numpy, scipy, pyproj

usage: tmssplit.py [-h] [-z ZOOM] [-n NAME] [-s SIZE] [-p PROJ] [-t THREADS]
                   inputfile outputdir

Split a big GeoTIFF image to TMS tiles.

positional arguments:
  inputfile             input GeoTIFF file
  outputdir             output directory

optional arguments:
  -h, --help            show this help message and exit
  -z ZOOM, --zoom ZOOM  zoom level(s), eg. 15 or 14-17
  -n NAME, --name NAME  image file name format, default {z}_{x}_{y}.png
  -s SIZE, --size SIZE  image size in px, default 256px
  -p PROJ, --proj PROJ  set projection id
  -t THREADS, --threads THREADS
                        set thread number

-z is required
