Dutch Springs, Bethlehem PA June 1st 8am-6pm
Are you ready to take your shipwreck diving and survey skills to the next level, or just curious about art in rapid digital survey? Building on introductory techniques covered at the last BTS workshop, we will review current survey techniques before practicing rapid photogrammetric 3D survey. With little more than a camera, a laptop, and a bit of know-how, you will build scaled-3D models right after your dive! Handouts will be provided, so you can have a guide for the future.
Registration: Currently full - looking forward to seeing you all soon!
Must be a current NYCSG member with all waivers up-to-date.
