Static Map

A small, python-based library for creating map images with lines and markers.

Example

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

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

Installation

StaticMap is a small library, all it takes is python and two python packages: Pillow and request. Install staticmap via:

pip install aiostaticmap

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. http://a.tile.osm.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 src import StaticMap, CircleMarker

m = StaticMap(200, 200, url_template='http://a.tile.osm.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 = await m.render(zoom=5)
image.save('marker.png')

Show Ferry Connection

from src 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 = await m.render()
image.save('ferry.png')

Show Icon Marker

from src 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 = await m.render()
image.save('icons.png')
