Title
Hydro Break Lines for Streams and Lakes 2011 - [Indiana] {2020}
Description
2016-2020 Hydro BreaklinesThe hydro break lines for lakes and stream represent the edge of bank in Indiana. These were created from 2016-2020 Lidar data. Class 2 (ground) lidar points to support hydro-flattened raster DEMs. The Indiana Lidar Program collected lidar data based on USGS specifications with a nominal pulse spacing (NPS) of 2 points per square meter.Hydro break lines were created according to USGS specifications, which include a minimum stream width of 30 meters and a minimum water body area of 2 acres. To provide detailed surface elevation data for use in conservation planning, design, research, floodplain mapping, dam safety assessments, and elevation modeling. Ground Conditions for this Lidar data were collected in spring (2016-2020), with no snow on the ground and rivers at or below normal levels.2011-2013 Hydro BreaklinesThe hydro break lines for lakes and stream represent the edge of bank in Indiana. These were created from 2011-2013 Lidar data. Class 2 (ground) lidar points to support hydro-flattened raster DEMs. The Indiana Lidar Program collected lidar data based on USGS specifications with a nominal pulse spacing (NPS) of .5 points per square meter.Hydro break lines were created according to USGS specifications, which include a minimum stream width of 30 meters and a minimum water body area of 2 acres. To provide detailed surface elevation data for use in conservation planning, design, research, floodplain mapping, dam safety assessments, and elevation modeling. Ground Conditions for this Lidar data were collected in spring (2011-2013), with no snow on the ground and rivers at or below normal levels.
