Radius maps by city
Choose a known city center and open a prefilled map, or search for another location in the main radius tool. A radius shows straight-line geographic coverage, not actual drive time.
Buenos Aires
The Río de la Plata shoreline lies to the east; circles extend over river water.
Brisbane
The Brisbane River winds through the metro and crossing choices change accessibility.
Melbourne
Port Phillip Bay and urban sprawl make radius coverage different from driving time.
Sydney
Sydney Harbour and the coastline cause many city-center circles to contain water.
Vienna
The Danube area intersects city neighborhoods, but the radius excludes transport service restrictions.
Dhaka
A dense riverine urban setting makes straight-line circles poor proxies for commute time.
Rio de Janeiro
Guanabara Bay and steep hills split the urban region, so water and terrain enter many radius circles.
São Paulo
Hills and a very extensive metropolitan area complicate reachability inside the same geometric radius.
Montreal
The island geography of Montréal makes bridges important for any travel-based area analysis.
Toronto
Lake Ontario is directly south of the city core; a circle can include a large water area.
Vancouver
The Burrard Inlet, mountains and bridges strongly affect accessible travel around Vancouver.
Santiago
The Andes rise east of Santiago. A radius is not a road travel-time boundary.
Beijing
Very large urban rings make a straight-line circle only an initial geographic screening tool.
Hong Kong
Islands and steep mountains can sit within short radii while road access is limited.
Shanghai
The Huangpu River divides parts of the city; travel routes differ from direct distances.
Bogotá
Mountain terrain limits routes that appear short when measured as the crow flies.
Prague
The Vltava river winds through the city; a radius crosses it regardless of bridge placement.
Copenhagen
Coastal water enters circles east of the city and crossing bridges matters for travel.
Cairo
The Nile passes through the city, and desert margins can fall inside outer radii.
Helsinki
The Baltic coastline and surrounding islands influence the land area inside a radius.
Lyon
Two major rivers meet in Lyon, making straight-line coverage different from bridge-based travel.
Paris
Paris has a relatively compact inner-city core; its suburban ring extends much farther than a central-city circle.
Berlin
A city-center radius covers multiple districts, but does not follow rail or road travel times.
Munich
Urban blocks and surrounding suburbs are inside a circle independently of transport access.
Athens
Surrounding hills and the Saronic Gulf affect what lies inside a metropolitan radius.
Bengaluru
City-scale circles can include very different neighborhood densities and transport conditions.
Delhi
The Yamuna River and extensive suburbs matter when interpreting city-scale circles.
Mumbai
Mumbai coastline and long peninsula make many circle directions cross the sea.
Jakarta
Coastal floodplains, canals and traffic affect how a circle translates to travel times.
Dublin
Dublin Bay opens to the east and changes how much of a radius is usable land.
Milan
Transport service areas and a geometric radius are different, especially around an extensive metro.
Rome
A circle cuts across different neighborhoods and does not capture the city historic street network.
Osaka
The Osaka Bay waterfront and dense transit corridors create uneven practical coverage.
Tokyo
A circle can cover many wards, but rail travel times vary with network routes.
Nairobi
Mixed urban and park land fall within the same circle; there is no population calculation.
Kuala Lumpur
Hilly terrain and ring roads complicate real drive-time estimates.
Guadalajara
This radius represents a geographic circle, not distance on metropolitan road corridors.
Mexico City
High elevation and a wide urban basin make straight-line circles unsuitable for estimating trip duration.
Casablanca
Atlantic coastline limits the on-land portion of any west-facing coverage circle.
Kathmandu
Mountain valleys and slopes create large differences between geometric and road distances.
Amsterdam
Canals and waterways make direct road coverage more complex than a circular outline.
Auckland
Two harbors narrow the isthmus; radius circles often cover water.
Wellington
Steep hills and Wellington Harbour limit the usable road coverage inside a circle.
Lagos
Lagoon water and island connections can make short map distances long trips.
Oslo
The Oslofjord and rising hills make circle coverage different from service area reach.
Islamabad
The Margalla Hills lie nearby; mountain topography restricts ground travel.
Karachi
Coastal water, port areas and road congestion affect practical travel within a radius.
Lahore
A geometric radius can cross administrative boundaries and does not represent road travel time.
Lima
The Pacific coastline means some geometrically covered area is open water.
Manila
Manila Bay and dense road networks can put water and slow routes inside a radius.
Warsaw
The Vistula River crosses a downtown radius. Geometric distance is not commute distance.
Lisbon
The Tagus estuary covers some circle directions; bridges become important for travel.
Doha
The Gulf coastline means many directions within a circle can lead into water.
Moscow
Large urban rings and transport infrastructure affect travel times far more than simple radial distance.
Riyadh
A large inland metro with dispersed districts; radius distances do not predict driving time.
Singapore
The island coastline determines how much of each radius is land, and cross-border circles may reach Johor.
Cape Town
Table Mountain and the Atlantic coast constrain road reach inside geometric circles.
Johannesburg
The urban footprint stretches across several municipalities; travel time varies independently of a radius.
Seoul
The Han River crosses the city; a radius does not account for river crossings.
Barcelona
The Mediterranean coast and nearby hills limit the useful on-land share of a city-center circle.
Madrid
Central Madrid is inland. The radius measures geographic coverage without regard to ring-road access.
Stockholm
Stockholm spreads across islands, so waterways are important for real accessibility.
Zurich
Lake Zürich and nearby hills make straight-line coverage quite different from road access.
Bangkok
The Chao Phraya River is near the center and makes actual trips depend on crossings.
Istanbul
The Bosphorus divides Europe and Asia; a small radius can cross continents but not a short road journey.
Abu Dhabi
The city islands and coastal waters occupy parts of radius circles.
Dubai
The Persian Gulf coast and extensive highway corridors change real-world accessibility.
Birmingham
This inland metro has a large network of roads; radius distance still differs from actual driving routes.
London
The Thames crosses the center; a radius can span multiple boroughs and is not a commuter-rail catchment.
Manchester
A central circle reaches across local council boundaries, which are not shown by a geometric radius.
Atlanta
A radius includes different suburban corridors; actual driving distances vary with road layout.
Austin
The Colorado River and urban hills affect real road paths compared with straight-line distance.
Boston
The harbor and river crossings matter for actual travel times within a small geometric circle.
Chicago
Lake Michigan lies east of downtown. Any circle drawn around the Loop includes lake surface.
Dallas
North Texas communities spread across a large area, so a fixed distance circle is only a first planning screen.
Denver
Front Range mountain terrain west of the metro changes road accessibility inside regional circles.
Houston
Houston has a broad metropolitan footprint. The same radius can include both dense centers and lower-density suburbs.
Los Angeles
The city extends over a large metro area. A downtown circle is not a measure of travel time in traffic.
Miami
Coastal water and the Everglades limit practical road coverage despite a symmetric radius outline.
New York City
The center is on Manhattan, an island separated from neighboring boroughs by rivers. A straight-line circle can cross water.
Philadelphia
The Delaware River is close to the city core and crosses the city-region boundary.
Phoenix
Desert terrain and mountain preserves can break up what appears to be a continuous straight-line coverage circle.
San Francisco
The peninsula and San Francisco Bay mean a circle may cover substantial water rather than accessible land.
Seattle
Puget Sound and Lake Washington break direct land access inside many city-scale radius circles.
Washington DC
The Potomac River and state boundaries make a radius cross jurisdictions without reflecting commute paths.
Hanoi
The Red River shapes city mobility; a radius ignores its crossing points.
Ho Chi Minh City
The Saigon River and canal network limit direct road access inside a circle.
