IGIC - Indiana GIS Local-Resolution NHD Applications for Surveyors
Friday, January 18, 2012 (12:45 pm – 3:30 pm)
Abstract
Extensive statewide flooding during 2008 caused 82 of 92 Indiana counties to receive the Presidential Disaster Declaration. In 2010, federal funds from the 2008 flooding became available for flood mitigation support and are being used by the state to acquire new Orthophotography (digital imagery), LiDAR (digital elevation data) and to update the State’s National Hydrography Data (NHD) GIS data set.
The State of Indiana Geographic Information Officeworking with IGIC’s Waters Workgroup has implemented a program across Indianato create a new Local-Resolution NHD dataset to replace the existing High-Resolution U.S. Geological Survey’s NHDdata. This new Local-Resolution NHD data for Indianarepresents a significant increase in the amount of information available (up to a 500% increase), while also improving the mapping accuracy of the NHD data by a factor of ten (from 1”=2,000’ to 1”=200’ scale or better).
This 3 hour workshop will provide detailed information about the NHD statewide programand how to use and further improve these data with more detailed local information. Topics will include:
- How to access the new Local-Resolution NHD data
- Incorporation of detailed CountySurveyor’s regulated drain map information into the new NHD
- Local confirmation / determination of new drainage classifications (stream or ditch)
- Local confirmation / determination of new names, or adding variant name to GNIS
- Local incorporation of farm drain tiles into the NHD
- Surveying and mapping applications of the Local-Resolution NHD data
Speakers
Mike Martin, David Nail, Dave Knipe and Phil Worrall
Mike Martin, Indiana DNR
After joining the Indiana Department of Natural Resources in 1988, Mike Martin began working with GIS 15 years ago. For the past nine years he has served as the agency’s GIS Coordinator. A member of the Indiana Geographic Information Council’s (IGIC) Board of Directors, Mike also serves as chair of the IGIC Waters Framework Dataset Workgroup. He received both his Bachelor of Science in Forestry degree and Master of Science degree from PurdueUniversity.
David Nail, USGS
David Nail is the USGS Geospatial Liaison to the states of Indiana and Kentucky. Before transferring to Indiana, David was a supervisory cartographer for the National Hydrography Data Program where he oversaw the production of High-Resolution subbasins. He began his USGS career in 1988 with the National Mapping Division in photogrammetry. David graduated from MissouriStateUniversity with a geology degree in 1981.
Dave Knipe, Indiana DNR
David is the Section Manager for the Central Basin Team at the Indiana Department of Natural Resources, Division of Water. He has 18 years of experience dealing with floodplain mapping and modeling issues with respect to the National Flood Insurance Program and the Indiana Flood Control Act.
