Aggregated movements between geographic locations as flow maps

With Flowmap.blue anyone can create visually attractive, intuitive and informative representations of often tangled data on geographic movements. Visual analytics of mobility data have never been easier.

“There was a need for a simple and intuitive tool that allowed people without special knowledge to make flow maps. Mapbox GL-JS and Deck.gl offered a great foundation to build this upon.”

Ilya Boyandin, creator of Flowmap.blue

Flowmap.blue is a free tool for representing aggregated numbers of movements between geographic locations as flow maps. Flowmap.blue is used to visualize various real-world phenomena in which pairs of locations are involved: origins and destinations. For example, urban mobility, travel or commuting behavior, bicycle sharing, human or bird migration, refugee flows, marine traffic, freight transportation, trade between countries, supply chains, scientific collaborations, or historical data.

Using Mapbox GL-JS provides geographic context for analysis and visualization. Flowmap.blue is capable of automatically clustering the locations and flows to make sure the maps are always readable. When zooming in, the clusters will gradually expand, so the level of summarization will automatically adapt to the map zoom level.

Until recently, making flow maps involved manual drawing, knowledge of programming, or specialized software. Praised for its ease of use, Flowmap.blue makes it possible to publish interactive flow maps from data spreadsheets, allowing anyone to create and share flow maps in no time.
