SELECTED PROJECTS

  • 2008-2013 Everglades Digital Elevation Model and Digital Water Surface Model development through the USGS Everglades Depth Estimation Network (EDEN) project: Dr. Xie has been a PI on a series of EDEN projects funded by the USGS.

"The Everglades Depth Estimation Network (EDEN) is an integrated network of real-time water-level monitoring, ground-elevation modeling, and water-surface modeling that provides scientists and managers with current (1991-present), on-line water-depth information for the entire freshwater portion of the Greater Everglades."  (http://sofia.usgs.gov/eden/).

  • 2011-2014 Research and Technical Assistance for Assessing: Climate Change, Sea Level Rise and Salinity Dynamics in the Greater Everglades, funded by the USGS, PI, Len Berry, Co-PIs, Caiyun Zhang, Zhixiao Xie,
  • 2010-2011 Feasibility of modeling impacts of sea level rise on foraging habitat of the Little Blue Heron in the Great White Heron National Wildlife Refuge, Funded by US Fish and Wildlife Service, PI, Dale Gawlik, Co-PI, Zhixiao Xie
  • 2006-2007 Detect invasive plants in Florida coastal areas using an image retrieval approach and remote sensed data, Funded by the Florida Fish and Wildlife Conservation Commission (FFWC), PI, Zhixiao Xie, Co-PI, Charles Roberts
  • 2005-2007 Location Strategies for the Initial Hydrogen Refueling Infrastructure in Florida, Funded by Florida Hydrogen Initiative, Lee Lines, Michael Kuby, Ronald Schultz, Zhixiao Xie
