Recent evidence suggests that backbarrier structure may act as an historical record of island development, and that backbarrier shorelines can be used as a proxy of an island’s past and future transgressive response to sea-level rise. The structure and stability of back-barrier shorelines are dependent on the geologic framework, defined here as the combination of nearshore topography, underlying geology, and modern geomorphologic forces. This antecedent framework controls and influences the present morphology, nearshore dynamics, and rates of transgression in response to sea-level rise while also acting as a feedback to the estuary ecology on the bayside. It is therefore surprising that our understanding of backbarrier geomorphology is limited. There is a need for an established link between process regimes and an island’s geomorphological history. This thesis bridges the current intellectual gap. The primary hypothesis of this project is that shorelines and bathymetric isolines share quantitative shape signatures indicative of their shared morphological past. To establish this link, the backbarrier shorelines of four United States National Seashores (Fire Island, NY; Assateague Island, MD; Santa Rosa Island, FL; and North Padre Island, TX) are digitized from aerial imagery using the marshline as the shoreline indicator to ensure the inclusion of (vital, sometimes inundated) ecosystems and sediment storage. The alongshore variation of this backbarrier shoreline, the mainland shoreline, lagoon bathymetry, and nearshore bathymetry are each quantified through wavelet analysis and their shape signatures are examined for spatial correspondence. Large and small scale variations are identified and attributed to the geomorphologic controls operating on the same scale and alongshore variation. The result is an improved understanding of how the geologic framework controls backbarrier shoreline shape, which is essentially an expression of the underlying geology.

Architecture is an act of agency, and a technology that can be learned by anyone for their own purpose. It evolved as a system of organization and a protective shell for our fragile bodies, a vast, complex technology that enables human survival. Yet despite its universal nature, we have artificially limited our control over it, and who has access to it; we limit its potentials, its adaptive capacities, its diversity, and our continued survival. Walled-up in universities, behind certifications and dissertations, we have removed architecture from the public’s mind so that few understand it and use it. The city, in its surging complexity, is ever more opaque; the systems, infrastructure, and regulations that govern its formation are hidden from view, behind doors, walls, and fences. Hack seeks to make the city legible and architecture accessible, by leveraging a growing tide of hacker culture, and its subcultures – makers and DIY drone enthusiasts – and their respective technologies. Since the birth of the computer, Hackers have sought to democratize information technology held by military, government, and corporate interests. In doing so they’ve provided a number of methods, that enable free sharing and collaboration between individuals, distributing problem-solving practices, open-source systems, hands-on education, and free access to tools, all applicable to the challenges and opportunities facing architecture and city building today. Hack bootstraps itself to these ideals with hands-on experiments and reflections on those experiments, reframing architecture as a basic skill, a technology to be used by anyone, democratizing architecture through online communities, and the Hacker culture, in order to define a new active role for the architect. Internalizing the Hacker Ethic, and appropriate existing technologies to build new tools – devices to survey space, architecture and the city. – Hack traces the construction of a kite, a model car, a quadrocopter, and a remote-control airplane, each capable of gathering intimate information about the local environment. Hack concludes by reexamining the role of the aerial view in making cities and exercising power, speculating on the potential to level the fields of perception through online co-operation and these small-scale cartographic technologies.

Aerial photography obtained by UAVs (Unmanned Aerial Vehicles) is an emerging market for civil applications. Small UAVs are believed to close gaps in niche markets, such as acquiring airborne image data for remote sensing purposes. Small UAVs will be able to fly at low altitudes, in dangerous environments and over long periods of time. However, the small lightweight constructions of these UAVs lead to new problems, such as higher agility leading to more susceptibility to turbulence and limitations in space and payload for sensor systems. This research investigates the use of low-cost fisheye lenses to overcome such problems which theoretically makes the airborne imaging less sensitive to turbulence. The fisheye lens has the benet of a large observation area (large field of view) and doesn't add additional weight to the aircraft, like traditional mechanical stabilizing systems. This research presents the implementation of a fisheye lens for aerial photography and mapping purposes, including theoretical background of fisheye lenses. Based on the unique feature of the distortion being a function of the viewing angle, methods used to derive the fisheye lens distortion are presented. The lens distortion is used to rectify the fisheye images before these images can be used in aerial photography. A detailed investigation into the inner orientation of the camera and inertial sensor is given, as well as the registration of airborne collected images. It was found that the attitude estimation is critical towards accurate mapping using low quality sensors. A loosely coupled EKF filter applied to the GPS and inertial sensor data estimated the attitude to an accuracy of 3-5° (1-sigma) using low-cost sensors typically found in small UAVs. However, the use of image stitching techniques may improve the outcome. On the other hand, lens distortion caused by the fisheye lens can be addressed by rectification techniques and removed to a sub-pixel level. Results of the process present image sequences gathered from a piloted aircraft demonstrating the achieved performance and potential applications towards UAVs. Further, an unforeseen issue with a vibrating part in the lens lead to the need for vibration compensation. The vibration could be estimated to ±1 pixel in 75% of the cases by applying an extended Hough transform to the fisheye images.
