Some documents have precise geographic data in form of GPS measured coordinates provided by the source.
For other documents this data is based on source metadata, with a certain precision level.
These levels (ordered from lowest precision to highest) are:
city (extracted data) and
coordinates (exact data).
The coordinates for lower precision geographic data are equal to their capital.
Geographic restrictions exist for:
- sourcegeo: location of the source of the articles (e.g. a page, a site, a publication).
- authorgeo: general location of the author of the article.
- articlegeo: location where the article was written.
