Despite heroic efforts by mapping communities on HOT's Tasking Manager, many parts of the world are still unmapped. Often the data does not reflect the reality on the ground, particularly when it comes to OSM tags.

Field-TM aims to help validating existing data with field verified information, and to add additional tags based on the situation on the ground. The goal is not to re-invent the wheel, but to leverage existing tech and coordinate the mapping amongst teams.
