Quantification and Mapping Sawgrass Marsh
Aboveground Biomass in the Coastal Everglades.
This project investigated sawgrass biomass estimation using
Landsat data and developed an object-based ensemble approach for
better biomass mapping in the coastal Everglades.
Produced sawgrass biomass maps on 4/24/2014 and 11/02/2014
in the coastal Everglades using Landsat data.
Examining the Effects of Salinity, Nutrients,
and Sea Level Rise on Vegetation Using Remote Sensing Spectroscopy
This project examines the effects of salinity, nutrients,
and sea level rise on plant stress using spectroscopy techniques by
collecting data under controlled environments. The project was
completed at FAU Greenhouse and hyperspectral laboratory by Dr. Donna
Selch, a former Ph.D. student of Dr. Zhang.
Produced salinity maps for 1999 and 1998 and comparison with
in-situ data using Landsat data.
Mapping Benthic Habits in the Florida Keys
Using Hyperspectral Remote Sensing Techniques.
This project explores the potential of the application of
fine spatial resolution hyperspectral imagery alone, and fusion of
20-m hyperspectral imagery and 1-foot aerial photography for benthic
habitat mapping in the Florida Keys.
Produced benthic habitat map in the Florida
Keys and comparison to a reference map using hyperspectral data.
Research and Technical
Assistance for Assessing: Climate Change, Sea Level Rise and Salinity
Dynamics in the Greater Everglades. PI: Dr. Leonard Berry, Co-PIs: Drs. Caiyun Zhang, Charles
Roberts, and Zhixiao Xie. U.S. Geological Survey (USGS).
South Florida is one of the world’s most vulnerable areas to
climate change, especially sea level rise. The potential adaptation
to sea level rise is complicated by the porous limestone geology of
the region, permitting salt water intrusion into important aquifers
and by the low level terrain in many areas which make even a
relatively small sea level rise problematic. Already past sea level
rise is impacting canal outfalls in Dade County. Scientist, city and
county officials and agencies that work in the affected area are well
aware of the pressing nature of these issues. The activities of this
project include: 1) synthesis, workshops and working groups on
climate change, sea level rise and salinity dynamics, and 2) changing
salinity as an indicator of restoration and climate change impacts on
the Greater Everglades.
Salinity Assessment in
Northeastern Florida Bay Using Landsat TM Data. PI: Caiyun Zhang, with
Dr. Zhixiao Xie as mentor. FAU Faculty Research Mentoring Program.
This project examines the potential of Landsat
Thematic Mapper (TM) for salinity assessment in the Greater
Everglades of South Florida with the Northeastern Florida Bay as
Water Quality Assessment in
Florida Bay Using Remote Sensing Techniques. PI: Caiyun Zhang,
Co-PIs: Drs. Tara L. Root, Zhixiao Xie, Marguerite Koch-Rose,
and Leonard Berry. FAU
2012 Seed Program.
The objective of this project is to examine the
potential of several remote sensors for assessing water quality in
Florida Bay, and test the sensitivity of spectral signatures measured
by a spectroradiometer for water samples collected from regions with
different nutrient concentrations and/or different seagrass species
Mapping Urban Composites Using Medium Resolution
This project developed object-based mixture
analysis techniques for mapping and quantifying urban composites
(impervious surface and vegetation) using multispectral Landsat
imagery and hyperspectral EO-1/Hyperion imagery.
