2016 Future Wetland Mapping Consortium Webinar Schedule
The WMC Steering Committee organizes bi-monthly webinars on topics of interest to the group. These webinars are held on the third Wednesday of every month at 3:00 p.m. eastern standard time (2:00 p.m. central, 1:00 p.m. mountain and 12:00 p.m. pacific).
If you haven’t used Go To Webinar before or you just need a refresher, please view our guide prior to the webinar here.
The Wetland Mapping Consortium is busy working on confirmation of webinar topics and presenters for 2016. Below you will find a draft list of future webinars to give you an idea of what we’re working on. Topics and dates are subject to change.
Mapping Coastal Storm Surge Flooding and Marsh Structure

Developing the tools for assessing and mapping marsh (and grassland) canopy structure – Elijah Ramsey III, U.S. Geological Survey
The capability to map marsh structure started with developing field methods that provided quantitative and reproducible 3-dimentional representations of marsh canopy structure. Methods of field collection were standardized over numerous studies and conversion of those standardized field measurements to vertical profiles of leaf area index (LAI) and average leaf angle distribution (LAD) was accomplished without user supplied estimates. LAI integrated to a volume metric and LAD were combined with polarimetric SAR data to create empirical relationships that were then used to create maps of marsh structure.
Radar and optical mapping of surge persistence and marsh dieback along the New Jersey Mid-Atlantic coast after Hurricane Sandy – Amina Rangoonwala, U.S. Geological Survey
Working to support coastal resilience, our studies have focused on providing resource management with effective strategies for identifying latent impacts to coastal resources. Within that effort, we have studied the capabilities of radar to map subcanopy flooding and its persistence in coastal marshes. We have also used optical to show how surge can cause widespread fresh and saline marsh dieback. Here we use a sequence of post landfall radar based surge extents to calculate surge persistence and link that to optical based pre to post landfall marsh live biomass change.
Elijah Ramsey III is a principal investigator of terrestrial and coastal ocean remote sensing and image processing in the U. S. Geological Survey, Wetland and Aquatic Research Center (formerly NWRC), Lafayette, Louisiana. He received his B.S. in Chemistry at the University of Oregon, his M.S. in Geophysics from the Georgia Institute of Technology in Atlanta, Georgia, and his Ph.D. from the Department of Geography at the University of South Carolina. His applied research is focused on producing consistent biophysical information directly relevant to sustaining critical natural resources that support the well-being of human and wildlife populations. As part of this focus, his work integrates data from passive to active and optical to radar systems that advance the response and strategic monitoring of natural resources and the human populations and facilities that occupy these environments.
Amina Rangoonwala received her M.Sc degree in Physics from the University of Karachi, Pakistan in 1984. After immigrating to the United States in 2000, she worked as a remote sensing specialist contractor at USGS National Wetlands Research Center, Lafayette, Louisiana until becoming an employ of USGS as an Earth Science Remote Sensing Geophysicist in 2014. She has worked on projects applying hyperspectral image analysis to determine the onset and progression of vegetation decline, detection of the invasive species occurrences, and leaf optics measurements for ground base validation. Her work also involves the integration of optical and radar satellite data to map the relationship between flood inundation extent and duration and marsh condition and the development of polarimetric radar methods for mapping canopy structure. She is called to map river and storm flooding in the coastal region of the central Gulf of Mexico during emergency activations of the International Charter.
