wms-tile-get 0.2

Fetch map tiles from WMS server and store them with WMTS convention

wms-tile-get

Fetch map tiles from WMS server and store them with WMTS convention. Typically the resulting tiles should be with EPSG:3857 projection.

The tool is similar to many others like wms-tiles-downloader but accept also geojson polygon as an area of interest.

Install

$ pip install wms-tile-get

Usage

Fetch tiles for an area (e.g. a city)

$ cd example/

$ wms-tile-get -s by_wms.json \
               -g munich.boundary.geojson \
               -z 10 \
               -o by_dop80c

-s defines WMS server parameters. -g defines the area(s) of interest (polygon area in geojson). -z defines the zoom level(s) of interest. -o defines output folder.

An area or boundary shapes (e.g. munich.boundary.geojson) of named areas can be downloaded from boundary.now.

Fetch tiles for a bbox area

$ wms-tile-get -s by_wms.json \
               -b 11.43,48.11,11.63,48.26 \
               -z 10 \
               -o by_dop80c

-b defines bounding box with longitudes and latitudes coordinates (i.e. EPSG:4326)

More example

fetch tiles for zoom level 1 to 5, and 10 and 13. All tiles will be fetched again when the tiles already exist in the output folder.

$ wms-tile-get -s by_wms.json \
               -g munich.boundary.geojson \
               -z 1-5 10 13  \
               -o by_dop80c  \
               --force

Requirement:

• Python
  • requests
  • supermercado
  • mercantile

Extra example

We can also only generate tile information with [x, y, z, minx, miny, maxx, maxy] tuples representing WMTS tile id and bbox.

$ cat munich.boundary.geojson       \
     | supermercado burn 18         \
     | mercantile shapes --mercator \
     | jq -c -r '[ [.id[1:-1]|split(",")|.[]|tonumber], .bbox ] | flatten | join(" ")' \
     > munich.tiles.bbox.z18.txt

The result munich.tiles.bbox.z18.txt looks like:

139445,90854,18,1280014.4756635614,6148135.933089867,1280167.3497201318,6148288.807146437
139446,90854,18,1280167.3497201318,6148135.933089867,1280320.223776702,6148288.807146437
139447,90854,18,1280320.223776702,6148135.933089867,1280473.0978332725,6148288.807146437
139448,90854,18,1280473.0978332725,6148135.933089867,1280625.971889843,6148288.807146437
139449,90854,18,1280625.971889843,6148135.933089867,1280778.8459464132,6148288.807146437
...

and then we can fetch tiles with such tile information.

$ wms-tile-get -s by_wms.json \
               -t munich.tiles.bbox.z10.txt \
               -o by_dop80c

-t defines tile information input file.
