Shrinking the Mercator projection to equal area

It’s been a while since we got our regular reminder that the Mercator projection is better for navigation on the tradeoff for distorted area at the poles. Neil Kaye provides an animation: Animating the mercator projection so countries and territories are correct size and shape in relation to each other.#dataviz #30Daymapchallenge #worldisnotflat #day28 pic.twitter.com/968GSBepA1 — Neil Kaye (@neilrkaye) November 28, 2021 See also the Mercator projection with the poles shifted...

Interactive shows map projections with a face

We’ve seen faces as map projections before, but this is 63 projections on one page. Plus, you can click and drag to change the center points to see how different parts of the face change. Tags: projections

Immersive digital waves to visualize nature

FLOW is an interactive art installation by Maotik that represents real-time weather data in the form of digital tides and waves that fill a room. I used 11 parameters to define the ocean form, we connect ourselves to a database and retrieve data such as sea levels, tide coefficient, humidity, weather cast, wind force, wind direction, weather cast, moon cycle, location, time of the day. When parameters such as wind...

Physical demo of how all maps are wrong

We’ve seen many one-off projects that show the distortions you get when you project a map. There’s just no avoiding them, when you convert a 3-D object onto a two-dimensional plane. Vox demonstrates and explains with an inflatable globe. Tags: projections, Vox

A more realistic perspective of country sizes

Most of us have seen the True Size of Africa graphic that squishes multiple countries into an area we normally see as much smaller. This is because of projections, which places a spherical planet in a two-dimensional space. Different projections have different tradeoffs. Even the True Size graphic has issues. This interactive by Zan Armstrong tries a different route by overlaying two globes against each other. I was inspired to...
