In short

  1. The file. GeoJSON, UTF-8, valid JSON, not in an archive, under 25 MB for the whole statement.
  2. The coordinates. WGS 84 decimal degrees, longitude first, at least six decimals, no duplicates once cut to six.
  3. The shapes. Points or polygons only; polygons closed, not crossing themselves, without holes; polygons for plots over four hectares unless cattle.
  4. The properties. ProducerName, ProducerCountry, ProductionPlace, Area spelled exactly; ProducerCountry a two-letter code on every plot in a Type II file; Area a number in hectares.
  5. The sense check. Every plot in its declared country, no plot declared twice, sizes plausible for the commodity.

This checklist covers the geolocation file only, not the rest of your due diligence. Everything on it is something the checker tests automatically; the list is here so you know what "passes" means, and why.

Keep a record of the check. The PDF check report (Starter and above) lists every finding, the file's SHA-256 and the rule set the file was checked against; the free change log lists every change made.
