Note about crediting and NFTs:

Please keep the printed message on the figures crediting my repository and OpenStreetMap (mandatory by their license).
I am personally against NFTs for their environmental impact, the fact that they're a giant money-laundering pyramid scheme and the structural incentives they create for theft in the open source and generative art communities.
I do not authorize in any way this project to be used for selling NFTs, although I cannot legally enforce it. Respect the creator.
The AeternaCivitas and geoartnft projects have used this work to sell NFTs and refused to credit it. See how they reacted after being exposed: AeternaCivitas, geoartnft.
I have closed my other generative art projects on Github and won't be sharing new ones as open source to protect me from the NFT community.

Tutorial

Plotting with prettymaps is very simple. Run:

prettymaps.plot(your_query)

your_query can be:

An address (Example: "Porto Alegre"),
Latitude / Longitude coordinates (Example: (-30.0324999, -51.2303767))
A custom boundary in GeoDataFrame format

import prettymaps

plot = prettymaps.plot('Stad van de Zon, Heerhugowaard, Netherlands')

You can also choose from different "presets" (parameter combinations saved in JSON files)

See below an example using the "minimal" preset

plot = prettymaps.plot(
    'Stad van de Zon, Heerhugowaard, Netherlands',
    preset = 'minimal'
)

Run

prettymaps.presets()

to list all available presets:

	preset	params
0	barcelona	{'layers': {'perimeter': {'circle': False}, 's...
1	barcelona-plotter	{'layers': {'streets': {'width': {'primary': 5...
2	cb-bf-f	{'layers': {'streets': {'width': {'trunk': 6, ...
3	default	{'layers': {'perimeter': {}, 'streets': {'widt...
4	heerhugowaard	{'layers': {'perimeter': {}, 'streets': {'widt...
5	macao	{'layers': {'perimeter': {}, 'streets': {'cust...
6	minimal	{'layers': {'perimeter': {}, 'streets': {'widt...
7	tijuca	{'layers': {'perimeter': {}, 'streets': {'widt...

To examine a specific preset, run:

prettymaps.preset('default')

	layers	style	circle	radius
perimeter	{}	fill: false lw: 0 zorder: 0	null ...	500 ...
streets	width: cycleway: 3.5 footway: 1 motorway: 5 pedestrian: 2 primary: 4.5 residential: 3 secondary: 4 service: 2 tertiary: 3.5 trunk: 5 unclassified: 2	alpha: 1 ec: '#475657' fc: '#2F3737' lw: 0 zorder: 4

background	.nan ...	fc: '#F2F4CB' zorder: -1

Insted of using the default configuration you can customize several parameters. The most important are:

layers: A dictionary of OpenStreetMap layers to fetch.
- Keys: layer names (arbitrary)
- Values: dicts representing OpenStreetMap queries
style: Matplotlib style parameters
- Keys: layer names (the same as before)
- Values: dicts representing Matplotlib style parameters

plot = prettymaps.plot(
    # Your query. Example: "Porto Alegre" or (-30.0324999, -51.2303767) (GPS coords)
    your_query,
    # Dict of OpenStreetMap Layers to plot. Example:
    # {'building': {'tags': {'building': True}}, 'water': {'tags': {'natural': 'water'}}}
    # Check the /presets folder for more examples
    layers,
    # Dict of style parameters for matplotlib. Example:
    # {'building': {'palette': ['#f00','#0f0','#00f'], 'edge_color': '#333'}}
    style,
    # Preset to load. Options include:
    # ['default', 'minimal', 'macao', 'tijuca']
    preset,
    # Save current parameters to a preset file.
    # Example: "my-preset" will save to "presets/my-preset.json"
    save_preset,
    # Whether to update loaded preset with additional provided parameters. Boolean
    update_preset,
    # Plot with circular boundary. Boolean
    circle,
    # Plot area radius. Float
    radius,
    # Dilate the boundary by this amount. Float
    dilate
)

plot is a python dataclass containing:

@dataclass
class Plot:
    # A dictionary of GeoDataFrames (one for each plot layer)
    geodataframes: Dict[str, gp.GeoDataFrame]
    # A matplotlib figure
    fig: matplotlib.figure.Figure
    # A matplotlib axis object
    ax: matplotlib.axes.Axes

Here's an example of running prettymaps.plot() with customized parameters:

plot = prettymaps.plot(
    'Praça Ferreira do Amaral, Macau',
    circle = True,
    radius = 1100,
    layers = {
        "green": {

                "landuse": "grass",

            "ec": "#2F3737",
            "lw": 0.5,
        }
    }
)

In order to plot an entire region and not just a rectangular or circular area, set

radius = False

plot = prettymaps.plot(
    'Bom Fim, Porto Alegre, Brasil', radius = False,
)

You can access layers's GeoDataFrames directly like this:

# Run prettymaps in show = False mode (we're only interested in obtaining the GeoDataFrames)
plot = prettymaps.plot('Centro Histórico, Porto Alegre', show = False)
plot.geodataframes['building']

Plot mosaic of building footprints

import numpy as np
import osmnx as ox
from matplotlib import pyplot as plt
from matplotlib.font_manager import FontProperties

# Run prettymaps in show = False mode (we're only interested in obtaining the GeoDataFrames)
plot = prettymaps.plot('Porto Alegre', show = False)
# Get list of buildings from plot's geodataframes dict
buildings = plot.geodataframes['building']
# Project from lat / long
buildings = ox.project_gdf(buildings)
buildings = [b for b in buildings.geometry if b.area > 0]

# Draw Matplotlib mosaic of n x n building footprints
n = 6
fig,axes = plt.subplots(n,n, figsize = (7,6))
# Set background color
fig.patch.set_facecolor('#5cc0eb')
# Figure title
fig.suptitle(
    'Buildings of Porto Alegre',
    size = 25,
    color = '#fff',
    fontproperties = FontProperties(fname = '../assets/PermanentMarker-Regular.ttf')
)
# Draw each building footprint on a separate axis
for ax,building in zip(np.concatenate(axes),buildings):
    ax.plot(*building.exterior.xy, c = '#ffffff')
    ax.autoscale(); ax.axis('off'); ax.axis('equal')

Access plot.ax or plot.fig to add new elements to the matplotlib plot:

from matplotlib.font_manager import FontProperties

plot = prettymaps.plot(
    (41.39491,2.17557),
    preset = 'barcelona',
)

# Change background color
plot.fig.patch.set_facecolor('#F2F4CB')
# Add title
plot.ax.set_title(
    'Barcelona',
    fontproperties = FontProperties(
        fname = '../assets/PermanentMarker-Regular.ttf',
        size = 50
    )
)

plt.show()

Use plotter mode to export a pen plotter-compatible SVG (thanks to abey79's amazing vsketch library)

plot = prettymaps.plot(
    (41.39491,2.17557),
    mode = 'plotter',
    layers = dict(perimeter = {}),
    preset = 'barcelona-plotter',
    scale_x = .6,
    scale_y = -.6,
)

Some other examples

plot = prettymaps.plot(
    # City name
    'Barra da Tijuca',
    dilate = 0,
    figsize = (22,10),
    preset = 'tijuca',
)

plot = prettymaps.plot(
    'Stad van de Zon, Heerhugowaard, Netherlands',
    preset = 'heerhugowaard',
)

Use prettymaps.create_preset() to create a preset:

prettymaps.create_preset(

Use prettymaps.delete_preset() to delete presets:

# Show presets before deletion
print('Before deletion:')
display(prettymaps.presets())
# Delete 'my-preset'
prettymaps.delete_preset('my-preset')
# Show presets after deletion
print('After deletion:')
display(prettymaps.presets())
