Fork of staticmap, a small, python-based library for creating map images with lines and markers.

Static Map 3

Static Map 3 is a fork of Static Map, a small, python-based library for creating map images with lines and markers.
The main purpose of this fork is to fix error handling on tile requests, to allow interrupting the execution (see PR on the original repository).

Changes since the fork are detailed in CHANGELOG.md.

Example

from staticmap3 import StaticMap, Line

m = StaticMap(300, 400, 10)
m.add_line(Line(((13.4, 52.5), (2.3, 48.9)), 'blue', 3))
image = m.render()
image.save('map.png')

This will create a 300px x 400px map with a blue line drawn from Berlin to Paris.

Installation

Static Map 3 is a small library, all it takes is python and three python packages: Pillow, requests and cachecontrol.

To install Static Map 3:

pip install git+https://github.com/SamR1/staticmap.git

To use Filecache as storage backend for cache:

pip install git+https://github.com/SamR1/staticmap.git@main#egg=staticmap3[filecache]

The default directory for cache is .staticmap_cache. It can be changed by exporting the environment variable STATICMAP_CACHE_DIR.

Usage

Create a new map instance:

m = StaticMap(width, height, padding_x, padding_y, url_template, tile_size)

parameter	description
width	width of the image in pixels
height	height of the image in pixels
padding_x	(optional) minimum distance in pixel between map features (lines, markers) and map border
padding_y	(optional) minimum distance in pixel between map features (lines, markers) and map border
url_template	(optional) the tile server URL for the map base layer, e.g. https://tile.openstreetmap.org/{z}/{x}/{y}.png
tile_size	(optional) tile size in pixel, usually 256

Add a line:

line = Line(coordinates, color, width))
m.add_line(line)

parameter	description
coordinate	a sequence of lon/lat pairs
color	a color definition Pillow supports
width	the stroke width of the line in pixel
simplify	whether to simplify coordinates, looks less shaky, default is true

Add a map circle marker:

marker = CircleMarker(coordinate, color, width))
m.add_marker(marker)

parameter	description
coordinate	a lon/lat pair: e.g. (120.1, 47.3)
color	a color definition Pillow supports
width	diameter of marker in pixel

Add a polygon:

polygon = Polygon(coordinates, fill_color, outline_color, simplify)
m.add_polygon(polygon)

parameter	description
coordinate	a lon/lat pair: e.g. [[9.628, 47.144], [9.531, 47.270], [9.468, 47.057], [9.623, 47.050], [9.628, 47.144]]
fill_color	a color definition Pillow supports
outline_color	a color definition Pillow supports
simplify	whether to simplify coordinates, looks less shaky, default is true

Samples

Show Position on Map

from staticmap3 import StaticMap, CircleMarker

m = StaticMap(
    200, 200, url_template='https://tile.openstreetmap.org/{z}/{x}/{y}.png'
)

marker_outline = CircleMarker((10, 47), 'white', 18)
marker = CircleMarker((10, 47), '#0036FF', 12)

m.add_marker(marker_outline)
m.add_marker(marker)

image = m.render(zoom=5)
image.save('marker.png')

Show Ferry Connection

from staticmap3 import StaticMap, Line

m = StaticMap(200, 200, 80)

coordinates = [[12.422, 45.427], [13.749, 44.885]]
line_outline = Line(coordinates, 'white', 6)
line = Line(coordinates, '#D2322D', 4)

m.add_line(line_outline)
m.add_line(line)

image = m.render()
image.save('ferry.png')

Show Icon Marker

from staticmap3 import StaticMap, IconMarker

m = StaticMap(240, 240, 80)
icon_flag = IconMarker(
    (6.63204, 45.85378), './samples/icon-flag.png', 12, 32
)
icon_factory = IconMarker(
    (6.6015, 45.8485), './samples/icon-factory.png', 18, 18
)
m.add_marker(icon_flag)
m.add_marker(icon_factory)
image = m.render()
image.save('icons.png')

Alternatives

With papermap there is also a spin-off project dedicated to print maps.
