Download tiles from Tile Map Server (online maps) and make a large image.
If GDAL is installed, 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, numpy, requests/httpx, GDAL (optional)
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] [-g]
[output]
Merge TMS tiles to a big image.
positional arguments:
output output file
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
-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
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
