Create beautiful maps from OpenStreetMap data

prettymapp 🖼️

Prettymapp is a webapp and Python package to create beautiful maps from OpenStreetMap data

Based on the prettymaps project

Prettymapp is based on a rewrite of the fantastic prettymaps project by @marceloprates. All credit for the original idea, designs and implementation go to him. The prettymapp rewrite focuses on speed and adapted configuration to interface with the webapp. It drops more complex configuration options in favour of improved speed, reduced code complexity and simplified configuration interfaces. It is partially tested and adds a streamlit webapp component.

Running the app locally

You can use the webapp directly under prettymapp.streamlit.app or run it locally via:

git clone https://github.com/chrieke/prettymapp.git
cd prettymapp
uv sync --extra streamlit
uv run streamlit run streamlit-prettymapp/app.py

Python package

You can also use prettymapp without the webapp, directly in Python. This lets you customize the functionality or build your own application.

Installation:

pip install prettymapp

Define the area, download and plot the OSM data:

You can select from 4 predefined styles: Peach, Auburn, Citrus and Flannel.

from prettymapp.geo import get_aoi
from prettymapp.osm import get_osm_geometries
from prettymapp.plotting import Plot
from prettymapp.settings import STYLES

aoi = get_aoi(address="Praça Ferreira do Amaral, Macau", radius=1100, rectangular=False)
df = get_osm_geometries(aoi=aoi)

fig = Plot(
    df=df,
    aoi_bounds=aoi.bounds,
    draw_settings=STYLES["Peach"],
).plot_all()

fig.savefig("map.jpg")

You can also plot exported OSM XML files e.g. from openstreetmap.org:

from prettymapp.osm import get_osm_geometries_from_xml

df = get_osm_geometries_from_xml(filepath="Berlin.osm")
aoi_bounds = df.total_bounds
...

Customize styles & layers

Edit the draw_settings input to create your own custom styles! The map layout can be further customized with the additional arguments of the Plot class (e.g. shape, contour_width etc.). Check the webapp examples for inspiration.

from prettymapp.settings import STYLES

custom_style = STYLES["Peach"].copy()
custom_style["urban"] = {
    "cmap": ["#3452eb"],
    "ec": "#E9724C",
    "lw": 0.2,
    "zorder": 4,
}

fig = Plot(
    df=df,
    aoi_bounds=aoi.bounds,
    draw_settings=custom_style,
    shape="circle",
    contour_width=0,
).plot_all()

You can also customize the selection of OSM landcover classes that should be displayed! Customize the default settings or create your own dictionary! See settings.py for the defaults.

from prettymapp.settings import LANDCOVER_CLASSES

custom_lc_classes = LANDCOVER_CLASSES.copy()
custom_lc_classes["urban"]["building"] = False # drops all building subclasses
custom_lc_classes["grassland"]["leisure"] = True # Include all leisure subclasses
custom_lc_classes["grassland"]["natural"] = ["island"] # Selects only specific natural subclasses

df = get_osm_geometries(aoi=aoi, landcover_classes=custom_lc_classes)
