3DHP FTN Info Forum: Creating a Hydro-enhanced Elevation Surface Using the Fully Integrated Elevation and Hydrography 3DHP Product | March 15, 2023
The 3DHP data model will require a hydro-enhanced elevation surface that reflects the flow characteristics of the hydrography network. The elevation data source will be enhanced with the z-values assigned to the vertices of the hydrography network so that the hydro-enhanced surface contains flowpaths reflected in the hydrography. We will discuss use cases for hydro-enforcement, […]

GIS 101 Past Webinars
GIS 101 is a webinar series presenting a non-technical overview of topics within GIS. This series was created as a tool for NSGIC members and others to use with the many people we deal with who could benefit from learning more about key GIS topics.
3DHP FTN Info Forum: Conceptual Model and the Mainstems logical data model for the 3D Hydrography Program | February 15, 2023
HY_Features is the international standard conceptual data model for surface hydrologic features which will be used as the basis for the 3DHP data model – the planned successor to the NHD. HY_Features concepts have been used for design of the National Weather Service Next Generation National Water Model (known as the Next Generation Water Resources […]

3DHP FTN Info Forum: Lessons Learned in Minnesota’s Approach to EDH
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. […]
