High quality maps is critical to field work. Experienced mappers may validate existing data to fix serious errors and invalidate an area for further work.

Task Briefing

Review the work of existing mappers using the HOT Task Manager. Our priority is routing and we will focus on Road network tasks 1,2,3,6. Pick and unreviewed area and throughly examine the area for the following issues:

Incomplete Task If there are numeruous roads missing and requires a lot more work to improve the quality, /invalidate this task/ so that others can continue to improve it. Add a comment clearly describing the reason for invalidating. Get @geohacker or @planemad to look before you mark it invalid.
