All examples above: Istanbul, radius = 3000m

Features

One-command maps — umap Istanbul and you're done
Sea & land rendering — Coastal cities render with proper water colors, not blank white
3 built-in styles — Minimal, Blueprint, Vintage — or register your own
Smart optimization — Detail level auto-adjusts based on map radius
Auto caching — Repeated areas generate instantly from local cache
Multi-format export — PNG, JPG, SVG, PDF
Python API — Full programmatic control for custom workflows
Parallel data fetching — Layers are fetched concurrently for speed

Installation

pip install umap-osm

Or install from source:

git clone https://github.com/U-C4N/Umap.git
cd Umap
pip install -e .

Requirements: Python >= 3.8

Quick Start

CLI

# Just a city name
umap Istanbul

# Coordinates
umap --coords "48.8566,2.3522"

# Pick a style
umap Istanbul --style blueprint
umap Istanbul --style vintage

# Adjust radius (meters)
umap "New York" --radius 8000

# Export format
umap Istanbul --format svg --output istanbul.svg

Style shortcuts

umap Istanbul --blueprint
umap Istanbul --vintage
umap Istanbul --minimal

Python API

Basic usage

import umap

# Create a map
result = umap.plot("Istanbul", radius=3000, style="minimal")

# Save it
result.fig.savefig("istanbul.png", dpi=300, bbox_inches="tight")

With extras (frame, north arrow, scale bar)

import umap
from umap.utils.drawing import add_frame, add_north_arrow, add_scale_bar

result = umap.plot("Istanbul", radius=5000, style="vintage")

add_frame(result.ax)
add_north_arrow(result.ax)
add_scale_bar(result.ax, length_km=2)

result.fig.savefig("istanbul_full.png", dpi=300, bbox_inches="tight")

Custom style

import umap

my_style = {
    "sea":        {"fc": "#1a1a2e", "ec": "none", "zorder": -2},
    "land":       {"fc": "#16213e", "ec": "none", "zorder": -1},
    "background": {"fc": "#1a1a2e", "zorder": -2, "pad": 1.02},
    "streets":    {"ec": "#e94560", "lw": 0.8, "zorder": 4},
    "building":   {"ec": "#533483", "fc": "#0f3460", "lw": 0.3, "zorder": 5},
    "water":      {"ec": "#1a1a6e", "fc": "#162447", "lw": 0.3, "zorder": 2},
}

umap.register_style("cyberpunk", my_style)
result = umap.plot("Tokyo", radius=4000, style="cyberpunk")
result.fig.savefig("tokyo_cyberpunk.png", dpi=300, bbox_inches="tight")

Multi-plot

import umap

plots = umap.multiplot(
    umap.Subplot("Istanbul", radius=3000, style="minimal"),
    umap.Subplot("Paris",    radius=3000, style="blueprint"),
    figsize=(24, 12),
)

Cache management

import umap

# Check cache stats
info = umap.get_cache_info()
print(f"Cache: {info['file_count']} files, {info['total_size_mb']:.1f} MB")

# Clear old entries
removed = umap.clear_cache(older_than_days=3)

Configuration

Create ~/.umap/config.yaml for persistent defaults:

default:
  style: minimal
  dpi: 300
  format: png
  cache_enabled: true
  radius: 5000
