Classification of mature Australian pines (Casuarina equisetifolia) using LIDAR data in Broward County, Florida
Title
Classification of mature Australian pines (Casuarina equisetifolia) using LIDAR data in Broward County, Florida.
Creator
Zumbado, Jennifer M., Florida Atlantic University, Roberts, Charles
Abstract/Description
The development of high resolution LIDAR DSM combined with digital infrared ortho-photography data enhances the ability to map canopy structures with a higher degree of accuracy and precision than with either data set alone. The purpose of this thesis is to map Australian Pine (Casuarina equisetifolia with a 85% or greater accuracy by creating a methodology that uses LIDAR and color infrared ortho-photography and to test it within three different landscape types within Broward County. LIDAR...
Show moreThe development of high resolution LIDAR DSM combined with digital infrared ortho-photography data enhances the ability to map canopy structures with a higher degree of accuracy and precision than with either data set alone. The purpose of this thesis is to map Australian Pine (Casuarina equisetifolia with a 85% or greater accuracy by creating a methodology that uses LIDAR and color infrared ortho-photography and to test it within three different landscape types within Broward County. LIDAR features below a determined height threshold (i.e. Deerpoint 25 ft) were eliminated and recoded to 0 to create Mask 1. NDVI technique separated non-vegetative features from vegetative features to create Mask 2. Mask 1 and Mask 2 were merged and overlaid on the raw LIDAR data set to perform isodata clustering, as well as density slicing to identify mature Australian Pines. Careful delineation of study areas is critical to obtain the highest possible accuracy. Density slicing proved to be a faster and less time consuming technique for achieving 85% level of accuracy than compared to isodata clustering.

canals at Cape Sable: A remote sensing perspective
Title
The canals at Cape Sable: A remote sensing perspective.
Creator
Ferik, Catherine Ann., Florida Atlantic University, Kennedy, William J.
Abstract/Description
Florida is home to five known aboriginal canoe canal complexes, most of which have been destroyed by urban development and the ravages of time. These canals were large undertakings suggesting an organized, chiefdom society and sedentary populations. Two of these complexes, Mud Lake and Snake Bight canals, are located on Cape Sable in South Florida. These canals remain fairly intact and are observable in the field and on high resolution aerial photographs. Digital image enhancement and...
Show moreFlorida is home to five known aboriginal canoe canal complexes, most of which have been destroyed by urban development and the ravages of time. These canals were large undertakings suggesting an organized, chiefdom society and sedentary populations. Two of these complexes, Mud Lake and Snake Bight canals, are located on Cape Sable in South Florida. These canals remain fairly intact and are observable in the field and on high resolution aerial photographs. Digital image enhancement and traditional ground truthing methods add valuable information to the study of Cape Sable's canals. Field work was completed with permission from Everglades National Park, study number EVER-00035, permit number EVER-2001-SCI-0035. Carbon-14 dates indicate that both of the canals were constructed at approximately the same time, during the Glades II and III periods, making the Cape Sable canals contemporaneous with Florida's other aboriginal canals. Information about these enigmatic features aids archaeologists in the quest to understand Florida's earliest inhabitants.

Abstract/Description
A land use classification system was designed for use with aerial photography in order to map four functional categories of land use in a study area divided into four quadrants. The data were analyzed for their spatial and functional relatedness to the operations of the Port of Baltimore. Where waterfront transshipment land use was dedicated to steel manufacturing and petroleum storage, nearly all test-category land use was located within two kilometers of the harbor in those quadrants.

Show moreA land use classification system was designed for use with aerial photography in order to map four functional categories of land use in a study area divided into four quadrants. The data were analyzed for their spatial and functional relatedness to the operations of the Port of Baltimore. Where waterfront transshipment land use was dedicated to steel manufacturing and petroleum storage, nearly all test-category land use was located within two kilometers of the harbor in those quadrants. In quadrants where it was engaged in the throughshipment of bulk, containerized, and general cargo, test-category land use still occurred primarily within two kilometers of the harbor, but was also distributed in large numbers six kilometers inland of the harbor. The results support the theory that the test-category land use is related to port activity, and that changes in land use patterns are associated with changes in port activity.

Interpretation of beach and nearshore morphodynamics, based on detailed geomorphological mapping
Title
Interpretation of beach and nearshore morphodynamics, based on detailed geomorphological mapping.
Creator
Benedet, Lindino, Florida Atlantic University, Finkl, Charles W.
Abstract/Description
Shorelines are prefigured by inherited geologic features and spatially-defined process-form relationships that require in depth study. This thesis is based on the interpretation, delineation, and analysis of coastal geomorphological features, as mapped from large-scale (e.g. 1:3600), digital, georeferenced, stereo-paired, color, aerial photography. The morphologic features identified include coral-algae reef tracts, rock reefs, sedimentary features such as bars, troughs, and sandflats, and...
Show moreShorelines are prefigured by inherited geologic features and spatially-defined process-form relationships that require in depth study. This thesis is based on the interpretation, delineation, and analysis of coastal geomorphological features, as mapped from large-scale (e.g. 1:3600), digital, georeferenced, stereo-paired, color, aerial photography. The morphologic features identified include coral-algae reef tracts, rock reefs, sedimentary features such as bars, troughs, and sandflats, and different types of engineering works. Interrelationships between these morphologic features are analyzed using a remote sensing-GIS/MIS (Geographic and Marine Information Systems) framework, and applying interpretive approaches in the analysis of beach and nearshore morphodynamics. Sediment and wave data is used to calculate the dimensionless fall velocity (O), which combined with local geomorphology, defines beach types. Special purpose geomorphological and morphodynamic maps generated here, together with assessment of beach types and analysis of downdrift erosion provides new insights and deep understanding of large scale coastal behavior, which is of great use to management planning strategies.

The Loxahatchee Slough is the largest wilderness island refuge existing in Palm Beach County, Florida. Cultural impacts have altered the hydrology of the area. This study provides a database of historical and geographical information regarding the Slough. Aerial photography and satellite imagery from pre- and post-channelization dates are classified according to vegetation ecosystems. GIS analysis is used to compare these diverse data sets.

Show moreThe Loxahatchee Slough is the largest wilderness island refuge existing in Palm Beach County, Florida. Cultural impacts have altered the hydrology of the area. This study provides a database of historical and geographical information regarding the Slough. Aerial photography and satellite imagery from pre- and post-channelization dates are classified according to vegetation ecosystems. GIS analysis is used to compare these diverse data sets. Changes in hydroperiod are examined, using vegetation as an indicator. Results show a general trend toward dryer hydroperiod vegetation land cover. Since 1979, the Army Corps of Engineers has raised water levels back toward pre-channelization levels, in a portion of the study area known as the Historic Region. Results indicate a positive response, with a net increase of longer hydroperiod vegetation in this region since 1979.
