State of New Jersey NHD / WBD Stewardship Conference NJ State Steward Report By: Craig Coutros, NJDEP April 15, 2009
NHD Contacts New Jersey USGS Geospatial Liaison Roger Barlow DC,DE,MD,NJ,Chesapeake Bay USGS POC Region 6 David Anderson NHD POC, Rolla, MO George Heleine NHD POC, Rolla, MO - Region 5 Principal Steward for New Jersey Larry Thornton Manager Bureau of Geographic Information SystemsTechnical POC for New Jersey Seth Hackman, GIS Specialist MOU Document: MOU signed Fall 2008
Current Projects Hydrography • Statewide conflation of NHD High resolution to Local resolution • Supplement 2002 Hydrography features with 2007 Imagery • Incorporate HUC12 boundary updates WBD Update • HUC12 revision based on HUC14 - Complete Imagery • Spring 2007 Imagery 1 ft pixel – 4 bands ( Color and CIR services) Land Use / Land Cover 2007 Update • Based on Spring 2007 Imagery : QC role ( 4th update –’86,’95,’02) Statewide LIDAR • Collection dates 2006 - 2009
Water Issues NJ State Agencies Utilize Water features – various sources Current Sources of Hydrography data • 1986 Hydrography USGS – dlg’s • NHD High resolution • 2002 Hydrography 1:2400 – Flowlines and Waterbodies Current Objectives • Conflation of NHD 1:24,000 to NJ features • 2002/2007 Hydrography 1:2400 – Flowlines and Waterbodies • Surface Water Quality Standards NHDLine events - reach code • Storet to WQX and to NHDPoint or events
2002 Hydrography Statistics of Change: Streams 1986 (1;24000) vs. Streams 2002 (1:2400) (no attributes)
