3DHP Info Forum: Lessons Learned in Minnesota's Approach to EDH Utilizing Culvert Mapping and Breachlines
Wednesday | November 16 | 3:00 - 4:30 pm ET
Presented by:
Rick Moore, MS, GIS Analyst and Lidar Data Steward, &
Sean Vaughn, GIS Hydrologist and Lidar Data Steward
Minnesota has been involved in developing tools and creating culvert inventories for use in culvert mapping for many years. These culvert inventories inform the work of DEM hydro-modification in the creation of elevation-derived hydrography. Pilot projects have been completed in two Lake Superior watersheds to create new hydrography that replicates the real world landscape hydrography. We will share lessons learned from developing culvert inventory applications as well as the data structure and metadata. We will also share how these culvert inventories are utilized in the DEM hydro-modification process to develop elevation-derived hydrography.
We'll use this presentation to kick off the NSGIC 3DHP FTN project culvert mapping activity. Join us to learn more about how you can engage.
Hope to see you there -
