Sapelo Island, GA

I have been working with Prof. Tony Stallins on a biogeography project which uses 

overlapping unmanned aerial photographs to construct dense 3D reconstruction 

of topography, a process known as structure from motion photography (SFM)

. This summer was spent preparing for data collection through the ordering of 

materials and performing some field tests of the helikite (a helium-filled balloon/

kite hybrid) and time-lapse photography (a GoPRO camera mounted to the helikite). 

The work this fall semester involves refining the techniques and equipment 

handling necessary to collect and process data from a local landscape feature. 

This tentatively may be a rock outcrop or the topography around a sinkhole. If 

possible, we may undertake mapping of topography on a barrier island, likely 

Sapelo Island (Georgia) or one of the islands in the Outer Banks of North Carolina. 

This trip would be more likely to occur during a continuation of the project in the 

spring semester so as to ensure that our data collection techniques are refined and 

potential sources of error are mitigated.
The research involves the capture and use of aerial photographs to construct 

three-dimensional maps using freely available software. These maps can record 

horizontal and vertical positions of a surface at high resolutions, making it a low 

cost alternative for pricier, airplane-mounted LIDAR data collection. My goal is to 

utilize the aerial photos of a feature or landscape to perform a 3D reconstruction

using VisualSFM and other shareware. This research fits into a larger research

agenda involving the mapping of maritime dune plants and their topography.
