Creator
Stoddard, Mary Beth., Florida Atlantic University, Roberts, Charles
Abstract/Description
A new technique was devised that produces a LIDAR based predevelopment Digital Elevation Model and offers a more superior visualization, of the natural landscape prior to development, than the Bare Earth Model produced by Florida International University's Hurricane Center. Two locations in southeastern Florida have been chosen for this study. The first site is utilized as a control for testing the model and contains a present day ridge system that runs north and south through the Boca Raton...
Show moreA new technique was devised that produces a LIDAR based predevelopment Digital Elevation Model and offers a more superior visualization, of the natural landscape prior to development, than the Bare Earth Model produced by Florida International University's Hurricane Center. Two locations in southeastern Florida have been chosen for this study. The first site is utilized as a control for testing the model and contains a present day ridge system that runs north and south through the Boca Raton cemetery. The second site is a paleowatershed, the Yamato Marsh which was located in Delray Beach. Modeling of the marsh site will assist in delineating surficial geomorphic features before they were anthropogenically altered. The predevelopment Digital Elevation Model successfully represents human derived land-use changes and defines the watershed boundaries of the historic Yamato Marsh.

Title
A proposed expanded green space plan using GIS for natural areas in Palm Beach County.
Creator
Rainyn, Corrie., Charles E. Schmidt College of Science, Department of Geosciences
Abstract/Description
In the past 25 years, Palm Beach County has acquired more than 31 million acres of public preserves consisting of numerous native habitats that are home to threatened and endangered flora and fauna. Both endemic habitats and plant species benefit from expansion and connectivity through the adoption of native plants in surrounding areas. The next step in conserving these protected, larger areas is to identify ways to connect them in order to reduce their isolation and improve their likelihood...
Show moreIn the past 25 years, Palm Beach County has acquired more than 31 million acres of public preserves consisting of numerous native habitats that are home to threatened and endangered flora and fauna. Both endemic habitats and plant species benefit from expansion and connectivity through the adoption of native plants in surrounding areas. The next step in conserving these protected, larger areas is to identify ways to connect them in order to reduce their isolation and improve their likelihood of continued ecosystem health. This study aims to perform an analysis using a GIS database of Palm Beach County's Eastern urban areas to determine additional vegetation that currently exists on public lands and private preserves and to analyze and classify the vegetation for its potential conservation role, either as ; preserves, buffers, corridors or clusters connecting and enhancing existing natural areas.

Show moreThe purpose of this study was to explore outcomes of a GIS/GPS integration process: to (a) examine student responses to GIS and GPS inclusion in their curriculum, (b) determine whether a relationship exists between inclusion of GIS into existing K-12 curriculum and student achievement, (c) examine the effectiveness of GIS professional development for teachers, and (d) evaluate teacher perceptions of the value of integrating GIS into their existing curricula. This study was quantitative and quasi-experimental in design. The samples consisted of 1,425 students from one middle school and 62 teachers from Palm Beach County School District. Two instruments were used in this study: student surveys and teacher feedback forms. Data from the student surveys indicated that students perceive their learning is enhanced by inclusion of GIS and GPS. Data from the teacher feedback forms revealed positive perceptions of the GIS/GPS program as an integrative tool for their existing curricula and a positive assessment of the GIS professional development training. The relationship between GIS instruction and student academic achievement was evaluated, measured by FCAT reading scores and final grades in science and social studies. The findings support the constructivist theory that students learn best when actively engaged in the process. In this study standardized FCAT reading test results and science and social studies grades corroborate the students' perceptions that GIS and GPS integration enhances their learning. Study results show FCAT reading scores were higher for GIS students than for non-GIS students. The research further indicated a significant increase in FCAT reading scores for non-native English speaking GIS students and a significantly higher average science grade for non-White GIS students., The findings also show that students who had a greater frequency of GIS instruction had higher averages in science and social studies grades. Education reform requires bold initiatives and an organizational culture supportive of innovative ideas. The structured model for development and implementation of GIS in the K-12 public school system presented at the end of this study includes collaboration between district leadership, administrators and teachers, and a comprehensive approach to professional development.

Mapping and analyzing the Florida Reef Tract in Palm Beach County in relation to major storm events in a GIS database
Title
Mapping and analyzing the Florida Reef Tract in Palm Beach County in relation to major storm events in a GIS database.
Creator
Pitti, Joseph G., Charles E. Schmidt College of Science, Department of Geosciences
Abstract/Description
The Florida Reef Tract in Southeast Florida is made up of hard-bottom formations. The shape and size of the tract is constantly changing. One major factor contributing to these changes is the movement of sand. This is influenced by location-based, human-induced, and natural factors. These shifting sands cover or uncover reef structure. Images of the Florida Reef Tract in Palm Beach County were analyzed by the Department of Geosciences at Florida Atlantic University, using a partially...
Show moreThe Florida Reef Tract in Southeast Florida is made up of hard-bottom formations. The shape and size of the tract is constantly changing. One major factor contributing to these changes is the movement of sand. This is influenced by location-based, human-induced, and natural factors. These shifting sands cover or uncover reef structure. Images of the Florida Reef Tract in Palm Beach County were analyzed by the Department of Geosciences at Florida Atlantic University, using a partially automated method of mapping. There are notable changes in reef structure throughout the years 2004-2006, in which many major storm events occurred in the region. A time series analysis was conducted throughout these years. Losses and gains of reef structure were quantified and compared throughout the county as a whole, in beach renourishment project areas, and inlet intervals. Trends suggest that the major storms of 2004-2006 may have had effects on the reef tract.

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.

Show moreUrbanization is a fundamental reality in the developed and developing countries around the world creating large concentrations of the population centering on cities and urban centers. Cities can offer many opportunities for those residing there, including infrastructure, health services, rescue services and more. The living space density of cities allows for the opportunity of more effective and environmentally friendly housing, transportation and resources. Cities play a vital role in generating economic production as entities by themselves and as a part of larger urban complex. The benefits can provide for extraordinary amount of people, but only if proper planning and consideration is undertaken. Global urbanization is a progressive evolution, unique in spatial location while consistent to an overall growth pattern and trend. Remotely sensing these patterns from the last forty years of space borne satellites to understand how urbanization has developed is important to understanding past growth as well as planning for the future. Imagery from the Landsat sensor program provides the temporal component, it was the first satellite launched in 1972, providing appropriate spatial resolution needed to cover a large metropolitan statistical area to monitor urban growth and change on a large scale. This research maps the urban spatial and population growth over the Miami – Fort Lauderdale – West Palm Beach Metropolitan Statistical Area (MSA) covering Miami- Dade, Broward, and Palm Beach counties in Southeast Florida from 1974 to 2010 using Landsat imagery. Supervised Maximum Likelihood classification was performed with a combination of spectral and textural training fields employed in ERDAS Image 2014 to classify the images into urban and non-urban areas. Dasymetric mapping of the classification results were combined with census tract data then created a coherent depiction of the Miami – Fort Lauderdale – West Palm Beach MSA. Static maps and animated files were created from the final datasets for enhanced visualizations and understanding of the MSA evolution from 60-meter resolution remotely sensed Landsat images. The simplified methodology will create a database for urban planning and population growth as well as future work in this area.
