[OSM-dev] GSoC OpenSurveyor week report #7

Sat Aug 3 16:58:48 UTC 2013

Also, can you expand on the idea of recoding just timestamps.
Nowdays every device has GPS. The only benefit I see is saving battery with
dedicated GPS logger...
You would need subsecond precision time on the device running OpenSurveyor
- can you read that off GPS sensor? Network based time sync?

How is the JOSM plugin going? I would like to do an end-to-end test.
