How we handle evidence and corrections
Map explanations should distinguish a mathematical property, a dataset choice and an editorial recommendation. We aim to make each claim traceable and each limit visible.
Claims and sources
Projection properties are checked against author publications, mathematical references or documented implementations. Geographic figures identify the source model and scope. A number calculated from this project’s geometry is labeled as a boundary-model estimate, rather than being attributed to an official statistical agency.
Practical advice, such as choosing a file for a slide, is editorial guidance based on the features actually provided. We do not turn a preference into a mathematical guarantee. When the available source is a summary rather than a primary document, we identify that limitation beside the relevant claim.
Project attribution and AI assistance
Articles are drafted with AI assistance and attributed to Equal Earth Lab. The project name identifies responsibility for the page; it is not a fictional individual author. We do not invent qualifications, firsthand fieldwork or a human review that has not happened.
Automated geometry tests and browser checks verify specific behavior. They do not amount to independent legal, linguistic or cartographic certification. Publication records should state the review actually performed and the content version it covered.
Dates and changing facts
An article’s updated date reflects a substantive content change. A routine rebuild does not advance every date. News accounts distinguish the event date from the date we checked a source. A newly accessible primary document can justify a revision; an unverified social-media claim does not by itself establish a new fact.
Mathematical examples remain tied to their stated model. If the geographic dataset or entity scope changes, affected comparisons and downloadable files must be regenerated and rechecked together. Quietly replacing one side of a comparison would undermine its consistency.
Corrections
Reports should identify the exact page, statement or map object and provide a supporting source where possible. We compare the definitions before deciding that two area figures conflict. A difference between land area and total surface area may require clearer wording rather than a change to the number.
Substantive corrections should explain what changed and why. Typographic fixes do not need a lengthy revision record. The corrections page provides a reporting format, and Contact identifies the available contact channel.
Independence and commercial features
The project is independent of the organizations it cites. A source link, software dependency or use of a named projection is not an endorsement. The delivered site does not contain paid rankings, sponsored map recommendations or advertising. Google Analytics measures site usage, as described in the privacy notice. Commercial features and tracking disclosures must remain consistent with their actual operation.
