Submit feedback / data corrections

Found a boundary drawn wrongly, a year that does not line up, an attribute code problem, or want a new feature? Describe it here and we will work through every report. Data corrections are the most welcome kind of feedback on this site.

Feedback type (required)

Pick the closest one; if unsure, choose “Other”.

Entity involvedoptional, but strongly recommended for data reports

Start typing and choose from the suggestions, e.g. BRA, Brazil. If it is not listed you can type it manually.

ADM0 = country boundary, ADM1 = first-level, ADM2 = second-level (municipality/district).

The year the geometry or attributes represent, e.g. 2022.

Please cover three things: current state (what is wrong), what it should be, and evidence. Example: in ADM1, the western boundary of “Mato Grosso do Sul” sits about 15 km east of the official IBGE 2022 boundary; evidence is the municipios layer on the IBGE website (link below).

{n} characters (at least {min} characters)

A link to an official source speeds things up enormously. A page or direct link from a government statistics office, official gazette or authoritative dataset (IBGE, DANE, geoBoundaries …).
This site is purely static and cannot receive file uploads. Upload your screenshot to an image host first (GitHub images, Imgur, SM.MS …), then paste the direct image URL here. You can also drag and drop images straight into the GitHub issue editor.
Leaving an email helps us follow up. Note: if you submit via GitHub issue this email becomes publicly visible; leave it blank if you prefer. We use it only to discuss this feedback.
