Type: Events

Location(s): US


Wednesday, April 16, 2014 – 3:00 p.m. EST

Part 1: The Minnesota NWI Update: A Case Study of Quality Assurance – Steve Kloiber, P.E., Ph.D., Wetland Monitoring Coordinator, Minnesota Dept. of Natural Resources

Abstract: Updating the NWI is a key component of Minnesota’s strategy to monitor and assess wetlands in support of efforts to ensure healthy watersheds and clean water. The NWI update is a major endeavor with a 10-year timeline and a multi-million dollar budget. One of the keys to a successful project, such as this, is a well-designed quality assurance (QA) program. This presentation will provide an overview of the Minnesota NWI update project and provide details on the QA program. A well-designed QA program has clear, measurable objectives, an effective framework, and solid integration throughout the production process. Performance measurement systems implemented for this project include multiple levels of visual inspection, field-checks, crowd-source data review, automated GIS checks, and formal statistical testing for classification accuracy.

Part 2: The Minnesota NWI Update--Integrating Semi-automated Mapping Techniques into Production Level Wetland Mapping – Robb Macleod, National GIS Coordinator, Ducks Unlimited

Abstract: The goal of the semi-automated mapping for the NWI update in Minnesota was to reduce the amount of time the photo interpreters spend on delineating wetland boundaries so they can focus their efforts on identifying the wetland class, water regime, and modifiers. At the beginning of the Minnesota NWI update project, wetland mapping methods were developed by the University of Minnesota. Ducks Unlimited modified these techniques so they could be used at a production level over large areas. This presentation will provide an overview on the process Ducks Unlimited and its partners have used in order to generate wetland boundaries for the photo interpretation process. The use of these techniques has the potential to increase the efficiency and accuracy of NWI updates throughout the country.
