Project 2010 - 11 • Two principal goals: • Program establishment • Edits and Updates • On establishment; • Focus has been on outreach; numerous meetings held, presentations given, promotional material distributed, etc. • Interest in NHD stewardship is difficult to pin down
Project 2010 – 11 (2) • On editing; • USGS visited WV for training Dec. 2010 • Virtual machine environment and software setup was slow • Two active editors; each completed just one HUC • Editing, too, was slow; technical issues requiring contact with USGS were frequent and learning curve was steep • We were unsatisfied with our own progress
2012 Project Overview • Basic goal: address data and policy issues associated with high change areas
2012 Project (2) • Fast facts: • 900-1200 miles of stream destroyed by surface mining • Unknown additional quantity via other land use change • No single dataset of buried streams exists • Related datasets (fills, mine boundaries, etc) useful in discovery need assessed for usefulness and accuracy
2012 Project (3) • Goals summarized: • Find streams • Generate policy and best practices for editing these streams • “Plan ahead” • Each of these statements is a Hemingway iceberg…
Finding Streams • Review of 5 datasets purporting to depict surface mining (+3 smaller area datasets) • Intersected with HR NHD and reviewed 10% of intersecting features to determine accuracy
Finding Streams (2) • First cut of source datasets established • Coordination with other agencies on this subject ongoing • Other disturbance; roads, urban dev’t, etc. • Summer 2012: Catalog streams in need of edits; stand alone dataset
Best Practices • Key facts and queries: • “Replacement drainage” is not recorded digitally • How permanent are these structures? • Are they visible on photos? Is digitization feasible? • What are the opinions of hydro researchers on this subject? (interest in and importance of these features) • How thorough should the feature level metadata be? Dates, mine names, permit numbers, etc.
Best Practices (2) • BP’s will (likely) be written on a “case” basis, depending on source data availability. Examples: • Stream buried by mine: delete reach • Stream buried by valley fill: replace reach with rock rip raps (if visible) • Stream altered due to road construction or urban dev’t: replace with agency provided data (culverts, etc) • Automated feature extraction
Planning Ahead • Can we anticipate where edits will need to be made? • WVDOT, WVDEP • Key components: • Selling the value of NHD • “inserting” NHD into agency workflows
Stewardship Errata • Re-starting editing post-conference • Outreach continues • Dave Arnold leading a training session at WV GIS Conference (general NHD, HEM, NHD Plus) • Widespread use of HR NHD is still an unrealized goal in WV
Conclusions • WV NHD Stewardship is: THANKS! Questions? Evan Fedorko WV GIS Technical Center 304.293.0557 evan.fedorko@mail.wvu.edu Photo credit: National Geographic
