Elevation Derived Hydrography and Low Impact Development – Up the Creek, with Many Paddles
Consider this webinar an “on-ramp” to the 3DHP (3D Hydrography Program) highway. As the practice of EDH (elevation derived hydrography) evolves, the body of information available about it is often too technical or too high-level for organizations to plan for its use. This presentation offers a “just right” collection of insights useful to those using surface water data, and to those making decisions that facilitate its use.

We’ll highlight what organizations should consider, plan for, and seek to mitigate. Real-world examples will bring clarity to topics that include:

- Why the buzz about EDH?
- Nuts and bolts of how EDH data is developed
- What is aerial lidar and how is it being used?

Join us for a judgement-free zone of surface waters learning, and leave equipped with practical steps for improving your hydrography data assets.
