The presenter is Dave Blodgett. Dave is a Civil Engineer with the USGS Water Mission Area and is also on assignment to NGTOC's Topographic Applied Research Team. 

2023 has been a busy year for 3DHP applied research and development teams. The initial 3DHP core data model and database contents for 3DHP v2023 are finalized. In this presentation, Dave Blodgett will describe the 3DHP core data model design and describe the purpose of key components of the data. Data according to the v2023 data model has been migrated from the final high-resolution NHD to an initial 3DHP database. The second half of the presentation will cover what has and what has not been included in this initial 3DHP database and what that means for users in the first operational year for the 3D Hydrography Program.
