Ahasan, great news, man... Do the volunteers not have their own android
phones. In the final days mapping hazaribagh and Kamrangirchar, they were
using osmand on their own devices. Also, I think there might some gps units
around that Jorieke left the previous time she was there.

In addition to the tracing, the technique that worked well in Kamrangirchar
was to send one mapper out for the day on a rickshaw, making sure they go
down every road to the end. We gave them a gps unit and a a phone and used
the combination of tracks to edit the road network (which HOT helped add)
ahead of field mapping with surveys. This worked well there because tracing
was hard due to the density of buildings.

Good luck and look forward to hearing how it went....!
