NHD Wiki: Markup Application and NHD Enhancements on the Horizon

Presentation Outline: 

NHD Markup Tool: The NHD Markup Application is a recently released web-based mapping communication tool that allows users to suggest edits, or “markups”, to the National Hydrography Dataset (NHD), Watershed Boundary Dataset (WBD), and NHDPlus High Resolution (NHDPlus HR). Anyone with a gmail account or ArcGIS Online account and the Chrome browser can suggest corrections and improvements to the data. This presentation will provide a demonstration of the Markup Application and discuss the life cycle of the markups.

Elehydro - Enhanced NHD for Texas: This presentation will provide an introduction to the EleHydro concept and examine the needs and benefits of developing enhanced NHD data in Texas.  Multiple examples of similar statewide EleHydro and Local NHD projects will be highlighted to further demonstrate possible implementation strategies, potential challenges, and opportunities to be considered as we collectively work toward the goal of developing these improved data resources for our state.
