TileStitcher
A High-Resolution Map-Image-Generator
What ?
You define a Coordinate-Bounding box, TileStitcher downloads and merges the tile-images. This will give you a high-resolution image from your map-section.
It supports multiple tiling schemes - even your own tile server if desired.
Why?
Want to print a map-segment for a giant poster? Awesome - this will meet your needs.
Improvements?
Bugs, ideas, improvements -let me now and we'll figure it out somehow.
This is great - thanks!
You're welcome :)
How to use
Install
Just use:
pip install map_tile_stitcher
It's as simple as that.
Use
Quick Start
from map_tile_stitcher.util.data_structures import Coordinate
from map_tile_stitcher.util.quick_start import QuickMapStitcher
# define your requesting area and resolution
start = Coordinate(48.139974, 9.20929) # lat, lon
end = Coordinate(48.111443, 9.271603) # lat, lon
zoom = 16 # from range 1..18, where 1 is course and 18 is very high-detail
# create Stitcher and start
stitcher = QuickMapStitcher()
stitcher.download_and_stitch(start, end, zoom)More advanced
Alternatively you can exactly specify the tile-cells you want to download as well as the download- and merging-options:
from map_tile_stitcher.util.data_structures import Coordinate
from map_tile_stitcher.util.quick_start import QuickMapStitcher
# define your requesting area and resolution
start = Coordinate(48.139974, 9.20929) # lat, lon
end = Coordinate(48.111443, 9.271603) # lat, lon
zoom = 16 # from range 1..18, where 1 is course and 18 is very high-detail
# convert lon-lat coordinates to grid-cell indices
start_grid_index = conversion.get_index_from_coordinate(start, zoom)
end_grid_index = conversion.get_index_from_coordinate(end, zoom)
# set up request bounding box
grid_bb = GridBoundingBox(start_grid_index, end_grid_index)
# download images
downloader = TileDownloader() # you can configure the downloader here
downloader.download_tiles(grid_bb)
# merge image
merger = TileMerger() # you can configure the merger here
merger.merge(grid_bb)As an example, you can change the Tiling style:
# ..
from map_tile_stitcher.definitions import DEFAULT_TILE_SERVERS
#..
# choose style / tiling server
tile_style = DEFAULT_TILE_SERVERS["STAMEN_TONER"] # black/white styled tiling
# download images
downloader = TileDownloader(tile_servers=tile_style)
downloader.download_tiles(grid_bb)
# merge image
merger = TileMerger()
merger.merge(grid_bb)
