TeamSurv is 2 year project, which started around the beginning of this year. It's an EU sponsored CoSuDEC project (Coastal Surveying of Depths with EGNOS to enhance charts) investigating the use of crowd sourcing to log position and depth data from seagoing vessels. It then processes the data to enhance the quality of nautical charts, and data sets for GIS systems as used by coastal engineers, for example.
As you can see form Tim Thornton's response the data is not yet suitable for navigational charting, although it is an aspiration.
It reminds me of Open Sea Map which has similar aspirations. Open Sea Map is about collecting the whole gambit of nautical information - although interestingly it can't yet take depth info as it's not 3D. Their market is focused on the leisure market adding additioinal local knowledge. Team Surv is more about collecting raw data to improve knowledge of the sea bed. Similar but different. Perhaps they should combine forces?
