monochromap 0.2.2

A highly opinionated way to paint and plot black and white map

MonochroMap

A compact library to paint and plot black and white map. Inspired and continued from StaticMap.

Some of the modifications are:

• changed default tile to stamen toner
• streamlined graphical component addition with only same function
• supported graphical component alpha/transparency blending
• fixed many iconmarker IO error in one image

Example

Draw Lines

This example code will show the location of Laugh Tale from intersection of coordinates given by 4 road poneglyphs.

from monochromap import MonochroMap, Line

m = MonochroMap()
line = Line(((13.4, 52.5), (2.3, 48.9)), '#ff000088', 15)
m.add_feature(line)

line = Line(((4.9041, 52.3676), (7.27, 46.57)), '#0000ff88', 15)
m.add_feature(line)

m.render()

Draw Points

This example code will show the hotspot of California forest fire. Don't ask why there is fire in the ocean, it's global warming.

from monochromap import MonochroMap, Point

m = MonochroMap()
for i in range(1000):

    lat = 36.7783 + rng.normal()
    lon = -119.4179 + rng.normal()

    p = Point((lon, lat), '#fb294344', 5)
    m.add_feature(p)

m.render()

Draw (any) Polygon

This example will show how to plot one instance of polygon, namely rectangle. Other shape of polygon is left as an exercise for the reader.

from monochromap import MonochroMap, Polygon

m = MonochroMap()

lon0, lat0 = (-6.114878, 106.731217)
lon1, lat1 = (-6.311491, 106.951200)
points = [[lat0, lon0], [lat0, lon1], [lat1, lon1], [lat1, lon0]]
m.add_feature(Polygon(points, '#ff000022', 'black'))

lon0, lat0 = (-6.156652, 106.912689)
lon1, lat1 = (-6.319975, 107.027262)
points = [[lat0, lon0], [lat0, lon1], [lat1, lon1], [lat1, lon0]]
m.add_feature(Polygon(points, '#00ff0033', 'black'))

lon0, lat0 = (-6.225684, 106.637555)
lon1, lat1 = (-6.319054, 106.807583)
points = [[lat0, lon0], [lat0, lon1], [lat1, lon1], [lat1, lon0]]
m.add_feature(Polygon(points, '#0000ff44', 'black'))

m.render()

Draw Icon (random image)

You can also plot any random image into the map. Here we will show the total number of covid patient on the world most adept country at defeating pandemic, according to reputable source, Plague inc.

from monochromap import MonochroMap, IconMarker

m = MonochroMap()
lat, lon = (75.939847, -42.161182)

for i in range(78):

    icon = IconMarker(np.array([lon, lat]) + np.random.uniform(-0.3, 6.7, 2), '../samples/covid.png', 0, 0)
    m.add_feature(icon)

icon = IconMarker(np.array([-17.456606, 63.992837]) + np.random.uniform(-0.1, 0.1, 2), '../samples/covid.png', 0, 0)
m.add_feature(icon)

m.render()
