I am working in a voluntary group that is creating navigation charts of the waterways in Ireland - We are tracing the shorelines and significant structures from aerial footage and adding our own depth datum collected by our members. Theses charts would be made available, free, to the members of the organisation we belong to, but the data raw would not be made available to anyone. It would be nice to put in some road networks and a few points of interest around the harbour areas for people visiting those harbours (shops, pubs, ATM etc) How do we stand if we wanted to use the data from this site to add to our charts? Would it be legal for us to use the data, and would we be obligated to provide our depth data in return? Our groups charter forbids us from making the depth data publicly available, so if that is a stumbling block then we will have to trace the roads in ourselves from the aerial images as well. regards,
