THE URBAN WORLD – HOW URBANISED IS OUR PLANET?

From points to polygons! 🌍

For Day 3 of the #30DayMapChallenge 2026, mapping the extent of urbanisation across countries and exploring how much of our world’s population lives in urban areas.

Data swizzling using #FME from Safe Software and Cartograph-ing in #QGIS.

Data Integration: Country-wise urban population data processed using #FME.

Visualization: Choropleth map showcasing the percentage of urban population by country.

Global Submarine Fibre-Optic Cable Network – Mapping the Invisible Highways of the Internet

#Data swizzling using #FME from Safe Software and Cartograph-ing continues with my second map for the seventh consecutive year of participation in the #30DayMapChallenge 2026, initiated by Topi Tjukanov. 

Today's theme is Lines, with a digital connectivity perspective!

Ever wondered how your WhatsApp messages, video calls and streaming content travel across continents in milliseconds?

Beneath our oceans lies an extensive network of submarine fibre-optic cables – the invisible highways of the internet. These cables connect continents, countries and landing stations, carrying the vast majority of international data traffic.

For Day 2, I explored the global submarine cable network, its landing stations and international connectivity corridors. I also brought in country-wise internet speed statistics to add another dimension to the story of global digital connectivity.

Environmental Performance Index (EPI) Air Pollution 2026 – Mapping the Global Air Pollution

#Data swizzling using #FME from Safe Software and Cartograph-ing (kicking off!) my first map for the seventh consecutive year of participation in the #30DayMapChallenge 2026, initiated by Topi Tjukanov, with an environmental perspective!

The EPI Air Pollution 2026 Index shown on the World Population Review website is a measure of how well countries perform in controlling certain air-polluting emissions. It is based on the Environmental Performance Index (EPI) developed by Yale University. EPI scores are performance scores, where higher is better;

Theme: Polygons
North Sentinel Island

North Sentinel Island is one of the Andaman Islands, an Indian archipelago in the Bay of Bengal which also includes South Sentinel Island. A protected area of India, it is home to the Sentinelese, an indigenous tribe in voluntary isolation who have defended—often with force—their protected isolation from the outside world. The island is about eight kilometres (five miles) long and seven kilometres (4+1⁄2 miles) wide, and its area is approximately 60 square kilometres (23 sq mi).
