Maps, Maps, Maps...
Maps are windows into hidden systems. While we navigate daily with Google Maps or Apple Maps, a fascinating ecosystem of specialized cartographic tools reveals infrastructure, movement patterns, and perspectives that standard maps obscure. Here are a few discoveries worth exploring.
The Invisible Grid: Open Infrastructure Map
Ever wondered where your electricity actually comes from? Open Infrastructure Map renders the invisible networks that power modern life: high-voltage transmission lines, substations, power plants, petroleum pipelines, and telecommunications infrastructure.
Built on OpenStreetMap data, the visualization transforms abstract "the grid" into tangible geography. Zoom into any region and trace power lines from generation to distribution, spot the submarine cables connecting continents, or identify the pipeline networks moving fuel across landscapes.
The project demonstrates how much critical infrastructure hides in plain sight - infrastructure we depend on but rarely see represented.
Global Arteries: Shipmap
Shipmap.org visualizes something equally invisible: the constant movement of global maritime trade. Created by data visualization studio Kiln in collaboration with the UCL Energy Institute, the interactive map shows merchant vessel movements throughout 2012, layered over bathymetric ocean depth data.
The visualization offers multiple lenses: track CO2 emissions from cargo ships, filter by freight type (containers, dry bulk, liquids, gas, vehicles), or simply watch the animated pulse of global commerce flow through chokepoints like the Suez and Panama Canals.
What emerges is a portrait of planetary-scale logistics - the physical reality behind "supply chain" abstractions.
Seeing Through Satellites: OSINT Mapping Tools
Researcher Michael Cruickshank has developed several open-source intelligence mapping tools that demonstrate how satellite data enables new forms of geographic analysis:
- Sudan Fire Map: Automated detection of arson attacks against civilians using NASA FIRMS thermal data and ESA Sentinel-2 imagery
- SARveillance: Creates synthetic aperture radar time series visualizations from Sentinel-1 data, originally developed to monitor military activity
- SARfish: Vessel detection using radar imagery, capable of identifying ships that have disabled their AIS transponders
These tools represent a broader shift: satellite data, once exclusive to governments and large corporations, now enables independent researchers to monitor environmental destruction, conflict zones, and maritime activity.
A Fish's Eye View: The Spilhaus Projection
Most world maps center on land masses, treating oceans as background. The Spilhaus Projection, designed over 75 years ago, inverts this logic entirely.
Centered on Antarctica, the projection presents Earth's oceans - 71% of the planet's surface - as a single, unified body of water. Continents become interruptions to an otherwise continuous seascape. Two small triangles marking the Bering Strait remind viewers this "sea" actually circles the globe.
It's a powerful reminder that cartographic choices shape perception. The same planet looks fundamentally different depending on what we choose to center.
The Map Is Not the Territory
Each of these projects reveals something that conventional maps hide: infrastructure networks, commercial flows, conflict patterns, oceanic continuity. They're reminders that every map is an argument - a choice about what to show, what to hide, and what to center.
The tools are freely available. The data is increasingly open. What remains is the question of what we choose to see.
