For questions about a map, its source data, reuse or accessibility, identify the relevant page and describe what you need.

Contact Equal Earth Lab: contact@equalearthlab.com.

Include the page and the question

A useful enquiry names the page, the place or file involved, and the result you are trying to understand. For a technical problem, include your browser and device and the steps that led to it. Avoid sending passwords or unrelated personal information.

For an area figure, please identify whether your source measures land area, total surface area or a particular boundary model. The methodology may already explain the difference.

Corrections and reuse

Use the corrections format for a suspected factual or geographic error. For reuse questions, include the exact download and intended use after checking sources and licenses. The public-domain status of the input data is separate from the terms for an original composition.
