The UN’s Equal Earth Resolution Is About More Than Projection Choice

On 4 September 2026, the United Nations General Assembly adopted resolution A/RES/80/307, “Correct the map”. The text encourages the use of Equal Earth and other equal-area projection methods when comparative landmass size matters. It passed by 164 votes to one, with six abstentions.

The obvious story is that Mercator makes Africa look too small and Equal Earth corrects the proportions. That story is true as far as it goes, but it misses what makes the decision significant. The resolution turns a familiar map from invisible infrastructure into a choice that institutions can be asked to justify.

That is the deeper change: a projection has always been a choice, but when a default becomes culturally dominant, it stops looking like one.

Familiarity is not neutrality

Most people meet a map of the world before they meet projection mathematics. The map appears on a classroom wall, in a news graphic or behind an online search. Its proportions become part of the background knowledge through which later maps are read.

Mercator's area distortion is well known. Its scale grows with latitude, enlarging Greenland, northern Canada, Europe and Russia relative to regions nearer the equator. Africa is about fourteen times the area of Greenland, but the familiar rectangular world can make the two look comparable.

That does not mean viewers calculate a country's power from its pixel count. Visual culture rarely works through such a simple mechanism. It means only that repeated images establish a hierarchy of apparent geographic presence, and that institutions should have a reason for reproducing that hierarchy when a suitable alternative exists.

Calling the projection “just a technical choice” does not make the effect non-political. Technical systems distribute attention all the time: through defaults, classifications, boundaries, data coverage and the order in which information appears. A decision can be mathematical in construction and social in consequence.

Equal Earth is the right answer to a specific question

Equal Earth preserves relative area. On an Equal Earth map, regions that occupy equal areas of the Earth's surface occupy equal areas on the page or screen. Its designers paired that commitment with a continuous, rounded form inspired by the visual familiarity of Robinson.

For a world map whose message depends on the size of countries or continents, that is a better answer than Mercator. The position does not need to be softened into “every projection has pros and cons” before it can be stated. Every projection does have trade-offs, but trade-offs do not make all choices equally suitable for a given task.

Mercator preserves local angles and historically supported constant-bearing navigation. Web Mercator supports a remarkably effective global tile system. Neither strength justifies using its world view for an area comparison. Equal Earth distorts local shapes and does not slot naturally into every web-mapping stack. Neither cost invalidates it when relative area is the property the map asks readers to compare.

The resolution is careful on this point. It identifies Equal Earth as a relevant option and encourages equal-area methods where comparative landmass size matters. It does not ban Mercator, prescribe one projection for every UN map or make Equal Earth compulsory for schools and technology companies.

That qualified wording is a strength. It replaces an unexamined default with a purpose-led standard, not with another universal default.

Representation is material even when it is not sufficient

An equal-area world map will not redistribute finance, improve the coverage of African spatial data or change the authority attached to geographic knowledge. It will not correct an outdated boundary, a biased indicator or the absence of local names. Projection reform is not a substitute for institutional reform.

But “not sufficient” is a poor test of whether an action matters. A map can be corrected without pretending that the correction completes a much larger political project, and in this case the practical cost of choosing an equal-area projection for an appropriate world map is low. The gain is that the image stops systematically overstating one set of landmasses relative to another.

There is also an educational gain. Equal Earth makes it easier to teach that a world map is constructed. Once readers see two defensible maps with visibly different proportions, the projection ceases to be a transparent window. That recognition can extend to other choices: who supplied the boundaries, which date the data describes, how missing values are drawn and what a category leaves out.

Projection literacy is a gateway to data literacy because it shows that the picture and the method cannot be separated completely.

The difficult work begins after the vote

Changing a static image is straightforward. Changing an institutional mapping practice is not.

Organisations need to identify which maps actually make area comparisons. Design systems need alternatives to one inherited basemap. Educators need language that explains the change without teaching that Equal Earth is distortion-free. Product teams need to decide what happens when a user moves from a global view into local interaction. Publishers need to distinguish the projection from the boundary dataset and political status of territories drawn on top of it.

These are not reasons to delay; they are the substance of implementation.

A credible policy would establish at least four expectations:

world maps that invite area comparison should use an equal-area projection;
projection choice should be recorded as part of the map's method;
another projection may be used when a different property or delivery constraint genuinely governs the task;
the change should be explained, especially in educational settings, rather than presented as the discovery of the one “true” flat world.

Without these distinctions, an institution can replace its wall map and leave the rest of its geographic practice untouched. With them, the resolution can influence procurement, software defaults, publication review and the way spatial evidence is documented.

Mapping products should expose the choice without exporting the burden

Projection-aware software often fails in one of two directions. It either hides the projection completely, making an infrastructure default appear universal, or presents a catalogue of hundreds of CRS definitions without helping the user connect them to a purpose.

Good product design sits between those extremes. It can recognise that a global choropleth should not inherit Web Mercator uncritically. It can distinguish a display projection from an analytical CRS. It can keep the selected coordinate operation with a derived result. It can explain that an equal-area overview and a tiled local map may legitimately use different projections.

This is where Geobble has a meaningful place in the argument. Natural-language access to GIS should not mean concealing the geographic method behind a fluent instruction. It should make the question easier to state while keeping the source, CRS, operation and limitation reviewable. A user who asks to “compare forest area by country” should not need to know every projection acronym before beginning—but the resulting workflow should still protect area and show how it did so.

That is a stronger product promise than pretending projection choice has disappeared, because the value lies not in automation alone but in legible judgement.

A projection can be correct while the map remains wrong

Equal Earth cannot decide which political boundaries to show. It cannot distinguish zero from missing data, test whether an indicator is comparable across countries or reveal that one region's source is ten years older than another's. It cannot prevent a misleading class break or a title that overstates causality.

This limitation is important because the public debate can load Equal Earth with claims its mathematics cannot carry. The projection gives regions their correct relative area. It does not give every part of the map an equally correct representation in every other sense.

That should make institutions more demanding, not less enthusiastic. If the lesson of the resolution is that an inherited technical default can shape geographic understanding, the same scrutiny belongs elsewhere in the map. Projection is one highly visible layer of a wider chain of choices.

The real standard is accountable cartography

The UN resolution matters because it gives institutional force to a simple proposition: a default should be able to explain why it is the default.

For area-based world maps, Mercator cannot provide a good answer. Its continued use in that context rests mainly on familiarity and technical inheritance. Equal Earth can provide one: it preserves the relationship the map asks the reader to see, while retaining a continuous form suitable for broad public communication.

The lasting success of the decision will not be measured only by how many maps acquire a rounded outline. It will be measured by whether schools, publishers, governments and software products become more explicit about what their maps preserve, what they distort and why their choices fit the task.

A new familiar map would be progress. A new habit of justification would be more valuable.
