Jin-Si R Over
Jin-Si Over is a geographer with the Woods Hole Coastal and Marine Science Center. A drone pilot and structure-from-motion specialist, she supports the Remote Sensing Coastal Change group and Aerial Imaging and Mapping group with GIS and surveying experience.
I have a background in micro-paleontology and working in coastal paleo-environments but gained more modern coastal mapping experience through the NOAA Hollings Scholars program in Hawaii - the beach stole my heart.
Now, as a geographer, my job enables me support coastal data collection, management, and scientific dissemination surrounding coastal responses to storms and hurricanes. This centers around GIS data, aerial imagery and stationary imagery, and processing imagery using structure-from-motion. I focus on datasets on Cape Cod National Seashore and on the Outer Banks. I am also a DOI and FAA licensed drone-pilot and assist in operations at beaches and marshes.
Additionally, I am active in science communication and mentoring efforts on the local scale and am passionate about fostering an inclusive and diverse scientific community.
Science and Products
Remote Sensing Coastal Change
We use remote-sensing technologies—such as aerial photography, satellite imagery, structure-from-motion (SfM) photogrammetry, and lidar (laser-based surveying)—to measure coastal change along U.S. shorelines.
DUNEX Aerial Imagery of the Outer Banks
The During Nearshore Event Experiment (DUNEX) project is a large collaborative scientific study focusing on understanding the consequences of coastal storms on the morphology of coastal ecosystems. By flying large sections of the coast and collecting still images using structure from motion (SfM) techniques, we hope to contribute high resolution (20cm) elevation maps for time series comparisons...
DUNEX Pea Island Experiment
The DUring Nearshore Event eXperiment (DUNEX) is an aggregation of multiple scientific organizations collaborating to increase understanding of nearshore processes. The U.S. Geological Survey (USGS) has chosen Pea Island National Wildlife Refuge as a study location to investigate and characterize the magnitude and timing of changes to coastal morphology (i.e., dunes, shorelines), bathymetry, and...
Aerial Imaging and Mapping
The Aerial Imaging and Mapping group (AIM), at the U.S. Geological Survey Woods (USGS) Hole Coastal and Marine Science Center provides UAS services to scientists to advance the science mission of the Coastal and Marine Geology Program. Scientists at the Woods Hole Coastal and Marine Science Center have been using UASs to acquire imagery of coastal and wetland environments, which is then used to...
