The Craftsmanship

Every print represents a precise coordinate intersection on Earth. By querying open-source geographic networks (OpenStreetMap), our systems capture the vascular rhythm of human settlements. Street networks are classified by road type — motorways, primary roads, secondary, tertiary, and residential — each rendered with distinct line weights and colors.

The resulting map abstracts traffic, buildings, and infrastructure into pure organic geometry. Water features (rivers, lakes, bays) and green spaces (parks, grasslands) are rendered as distinct layers. It is a visual print of where we walk, drive, and live.

Frequently Asked Questions

What is a map poster?

A map poster is a decorative art print that visualizes a city's street network, waterways, and parks as abstract geometric art. Cartographia generates map posters from OpenStreetMap data, rendering road hierarchies, rivers, and green spaces into high-resolution prints suitable for framing. Each poster is centered on precise geographic coordinates and available in 17+ color themes.

How are Cartographia map posters generated?

Cartographia map posters are generated programmatically using OpenStreetMap data. The system queries street network graphs, water features (rivers, lakes, bays), and park/green space data for a given city coordinate. The data is then rendered using matplotlib with theme-specific color palettes, gradient fades, and typography. Output is available in PNG (300 DPI), SVG, and PDF formats.

What cities are available as map posters?

Cartographia currently offers map posters for 26 cities worldwide including New York, Paris, Tokyo, London, Shanghai, Kyoto, Venice, Amsterdam, Singapore, Dubai, Seattle, San Francisco, Chicago, Helsinki, Budapest, Sydney, Melbourne, Mumbai, Marrakech, Rome, Barcelona, Moscow, Washington D.C., and more. Any city with OpenStreetMap coverage can be generated.

What themes are available for map posters?

Cartographia offers 17+ color themes including Classic Noir (black and white), Japanese Ink (sumi-e aesthetic), Neon Cyberpunk (vibrant pink and cyan), Autumn Gold (warm amber tones), Ocean Coast (cool blues), Pastel Dream (soft pastels), Architect Blueprint (cyan technical lines), Copper Patina (aged metallic tones), Emerald Mint, Deep Forest, Gradient Roads, Midnight Gold, Monochrome Blue, Sunset Peach, Terracotta Warmth, Warm Vintage Beige, and Contrast Zones.

What print quality and formats do map posters support?

Map posters are rendered at 300 DPI resolution in PNG format by default, suitable for giclée archival pigment printing on 200 gsm museum-grade paper. Default dimensions are 12×16 inches (30×40 cm). SVG and PDF vector formats are also available for unlimited scaling. Framing options include Oak Wood, Matte Black, Gallery White, or unframed print-only.

Is Cartographia free and open source?

Yes. Cartographia is an open-source project that uses OpenStreetMap data (© OpenStreetMap contributors) to generate map posters. The source code is available on GitHub at github.com/notsleeply/maptoposter. You can generate posters for any city worldwide using the command-line tool.
