Tearline App

Tearline provides open source intelligence to the public.

The National Geospatial-Intelligence Agency (NGA) is partnering with expert non-profit groups to grow public-facing, authoritative open source intelligence on various strategic, economic, and humanitarian intelligence topics that tend to be under-reported within in-depth or long-form formats.
