1. Using the Utility Network Analyst with the National Hydrography Dataset Indiana GIS Local Resolution NHD Applications for Surveyors ISPLS State Conference January 18, 2013

2. Coordination of Indiana GIS through dissemination of data and data products, education and outreach, adoption of standards, and building partnerships Using Utility Network Analyst with NHD NHD geodatabase network topology allows for analyzing waterflow Utility Network Analyst is Tool in ESRI ArcMap  ArcView (Basic) license, no extension required Requires NHD geodatabase hydrography dataset, not just feature classes/vector graphics  Hydro_Net_Junctions  NHDFlowline

3. Coordination of Indiana GIS through dissemination of data and data products, education and outreach, adoption of standards, and building partnerships Analyzing Water Flow with NHD Tools in the Utility Network Analyst Toolbar Show Flow Direction Determine common ancestors Find connected flowlines Trace downstream or upstream Find path upstream or downstream Find upstream accumulation

4. Coordination of Indiana GIS through dissemination of data and data products, education and outreach, adoption of standards, and building partnerships Using Utility Network Analyst with NHD Add data from the NHD geodatabase to the Map  Hydrography dataset HYDRO_NET  HYDRO_NET_Junctions  NHDFlowline Add Other data as needed (not required)
