Overview

Cities with grid patterns create some of the most striking and geometric map posters. The regularity and order of grid systems produce clean, minimalist compositions that highlight urban planning excellence.

​
Iconic American Grids

​
New York - Manhattan Grid

The Manhattan street grid is one of the most recognizable urban patterns in the world, established by the Commissioners’ Plan of 1811. 
python create_map_poster.py -c "New York" -C "USA" -t noir -d 12000
Distance: 12,000m
  • Captures full Manhattan island from Battery to Inwood
  • Shows the grid’s interaction with Broadway’s diagonal
  • Includes Central Park as a rectangular void in the grid
Theme: Noir
  • Pure black background with white roads
  • Maximum contrast emphasizes geometric precision
  • Modern, minimalist aesthetic matches NYC’s character
Alternative Theme: Contrast Zones
  • Shows density variations across neighborhoods
  • Highlights differences between avenues and streets
Grid HighlightsNew York’s poster beautifully shows:
  • The famous numbered street grid (1st to 220th Streets)
  • Avenues running north-south
  • Broadway’s diagonal disruption
  • Central Park’s rectangular green space
  • The contrast between gridded Manhattan and organic Brooklyn/Queens

​
San Francisco - Peninsula Grid

San Francisco’s grid system defies topography, creating the city’s famous steep streets. 
python create_map_poster.py -c "San Francisco" -C "USA" -t sunset -d 10000
Why San Francisco is UniqueUnlike flat grid cities, San Francisco’s grid:
  • Climbs over hills (Russian Hill, Nob Hill, Telegraph Hill)
  • Creates the famous steep streets
  • Shows multiple grid orientations
  • Demonstrates how grids interact with topography

European Grid Systems

​
Barcelona - Eixample District

Barcelona’s Eixample district features one of the world’s most distinctive urban grids, designed by Ildefons Cerdà in 1859. 
python create_map_poster.py -c "Barcelona" -C "Spain" -t warm_beige -d 8000
Octagonal Blocks (Chamfered Corners)
  • Blocks with chamfered (cut) corners create octagonal intersections
  • Improves visibility and traffic flow
  • Creates unique visual pattern
  • Distinctive spacing between blocks
Distance: 8,000m
  • Perfect for the Eixample district
  • Shows the grid’s regularity
  • Includes the transition to medieval Gothic Quarter
Theme: Warm Beige
  • Mediterranean aesthetic
  • Vintage, classical feel
  • Complements Catalan architecture
What Makes Barcelona SpecialThe Eixample grid poster shows:
  • Chamfered octagonal block corners
  • Diagonal Avinguda Diagonal cutting through the grid
  • Gaudí’s Sagrada Família within the grid
  • Passeig de Gràcia boulevard
  • Contrast with medieval Gothic Quarter’s organic streets

​
Other Notable Grid Cities

​
Chicago - Lakefront Grid

Chicago’s comprehensive grid system along Lake Michigan. 
python create_map_poster.py -c "Chicago" -C "USA" -t noir -d 12000
Chicago’s grid extends across the entire city, one of the most comprehensive in the world. The lakefront creates a natural boundary on the east.

​
Toronto - Linear Waterfront Grid

Toronto’s grid system along Lake Ontario. 
python create_map_poster.py -c "Toronto" -C "Canada" -t ocean -d 10000

​
Washington DC - L’Enfant Plan

While not a pure grid, Washington DC combines grid and radial patterns. 
python create_map_poster.py -c "Washington" -C "USA" -t blueprint -d 10000
Washington DC’s poster shows the unique combination of:
  • Rectangular grid (numbered and lettered streets)
  • Diagonal avenues (state-named) radiating from circles
  • The Mall’s monumental axis

Distance Recommendations for Grid Cities

Focused Grid

8,000-10,000mBarcelona (Eixample focus)Best for showing specific districts

Full City Grid

10,000-12,000mNew York, Chicago, San FranciscoComplete urban grid system

Metro Grid

12,000-15,000mLarge cities with extensive gridsShows grid interaction with surroundings

Theme Selection for Grid Cities

​
Best Themes for Geometric Patterns

Maximum ContrastPure black background, white roads - emphasizes geometric precision
-t noir
Best for: New York, ChicagoWhy it works: The high contrast makes the grid pattern pop, creating a modern, minimalist aesthetic that emphasizes the city’s geometry.

​
Advanced Grid Techniques

​
Centering on Specific Grid Areas

Use custom coordinates to focus on specific parts of the grid: 
python create_map_poster.py \
  --city "New York" --country "USA" \
  -lat 40.7580 -long -73.9855 \
  -t noir -d 8000

​
Print-Ready Grid Posters

Create high-resolution prints perfect for framing: 
python create_map_poster.py \
  -c "New York" -C "USA" \
  -t noir -d 12000 \
  -W 8.3 -H 11.7

​
Instagram-Ready Grid Maps

# Square format (1080 x 1080)
python create_map_poster.py \
  -c "Barcelona" -C "Spain" \
  -t warm_beige -d 8000 \
  -W 3.6 -H 3.6

​
Comparing Grid Systems

Create posters of different grid cities to compare their unique characteristics:
Characteristics: Large blocks, wide streets, comprehensive coverage
# New York - Dense, uniform grid
python create_map_poster.py -c "New York" -C "USA" -t noir -d 12000

# Chicago - Lakefront grid
python create_map_poster.py -c "Chicago" -C "USA" -t noir -d 12000

# San Francisco - Topographic grid
python create_map_poster.py -c "San Francisco" -C "USA" -t sunset -d 10000

​
Tips for Best Results

Emphasize the GridFor cities where the grid is the main feature:
  • Use high-contrast themes (noir, midnight_blue, contrast_zones)
  • Choose distances that show the full extent of the grid
  • Avoid themes that compete with the geometric pattern
Show Grid DisruptionsSome of the most interesting grid posters show where the pattern breaks:
  • Broadway’s diagonal through Manhattan
  • Diagonal Avinguda in Barcelona
  • Radial avenues in Washington DC
  • Water bodies interrupting the grid
Consider Grid ScaleDifferent grids have different scales:
  • Large blocks (NYC): Use 12,000-15,000m to show extent
  • Medium blocks (Barcelona): Use 8,000-10,000m
  • Fine grids: May need smaller distances to maintain detail
