Like so many natural areas in south Florida, the Dupuis Reserves' landscape has gone through extreme alteration due to numerous cultural activities. Activities including drainage, cattle ranching, and citrus farming have altered the reserves natural hydrology causing the formation of several watersheds. This hydrologic alteration has caused the once homogenous ecosystem to fragment into two separate landscapes: one dominated by drainage and human impact while the other remains in a relatively...
Show moreLike so many natural areas in south Florida, the Dupuis Reserves' landscape has gone through extreme alteration due to numerous cultural activities. Activities including drainage, cattle ranching, and citrus farming have altered the reserves natural hydrology causing the formation of several watersheds. This hydrologic alteration has caused the once homogenous ecosystem to fragment into two separate landscapes: one dominated by drainage and human impact while the other remains in a relatively natural state. This study will attempt to determine, with the use of remote sensing, geographic information systems and digital image classifications if culturally derived watersheds cause significant change in the spectral signatures of vegetation. Results indicate that when the study site is sectioned along culturally derived watersheds, classification accuracy is significantly improved.

Much of the recent research concerning the use of GIS has revolved around data quality. Types of errors inherent in GIS data layers, and also errors that may be produced through the creation and manipulation of data layers have been identified. Definitions of these errors, and observations of how these errors occur have been offered. However, the majority of the research is qualitative. It is known that positional variation is produced through differing interpretations and generalization of...
Show moreMuch of the recent research concerning the use of GIS has revolved around data quality. Types of errors inherent in GIS data layers, and also errors that may be produced through the creation and manipulation of data layers have been identified. Definitions of these errors, and observations of how these errors occur have been offered. However, the majority of the research is qualitative. It is known that positional variation is produced through differing interpretations and generalization of points, lines, and polygons, but it is not known to what extent. This information would be extremely helpful in allowing the user of the information to fine tune the application, based on the accuracy of the data. Providing this type of information is the goal of this research. Quantitative analysis of the results of a series of experiments will give a numerical range of possible positional errors produced through database creation via aerial photo interpretation.

Protecting Natural Resources, such as drinking water in terms of quality and quantity, is one of the missions of South Florida Water Management District (SFWMD). Water Supply Planning is one of the many projects at the Planning Department of the SFWMD, in which sixteen counties are analyzed to determine the most accurate population distribution for water supply distribution among the water utility companies.

Show moreProtecting Natural Resources, such as drinking water in terms of quality and quantity, is one of the missions of South Florida Water Management District (SFWMD). Water Supply Planning is one of the many projects at the Planning Department of the SFWMD, in which sixteen counties are analyzed to determine the most accurate population distribution for water supply distribution among the water utility companies. This thesis examines the current methodology which is used at the SFWMD, and addresses its shortcomings. It then introduces a proposed methodology, to improve population distribution analysis, by incorporating satellite imagery. Textural classification of satellite imagery will be used to extract residential neighborhoods from non-residential areas. The resultant residential areas, which is in the form of raster data, then will be converted to a vector coverage to be utilized as an additional source of data. Incorporating satellite imagery eliminates the assumption of homogenous population distribution, which the current methodology is based on and consequently, leads to a more accurate population distribution methodology.

- A simple model for estimating insolation from GOES satellite data.
- Creator
- Hopkins, Emily Elaine, Florida Atlantic University, Roberts, Charles, Charles E. Schmidt College of Science, Department of Geosciences
- Abstract/Description
-
South Florida summers are characterized by small intense convective storms which lead to extreme variations in local cloud cover. Estimating insolation from high-resolution satellite data accounts for these variations. A statistical model is presented for estimating incident solar radiation (insolation) using 1km x 1km resolution visible images from the GOES8 satellite. The model relates insolation to top-of-the-atmosphere radiation, readily available climate data, and cloud cover (from the...

A statistical model is presented for estimating incident solar radiation (insolation) using 1km x 1km resolution visible images from the GOES8 satellite. The model relates insolation to top-of-the-atmosphere radiation, readily available climate data, and cloud cover (from the satellite). Regression coefficients were developed and verified based on one month of insolation measurements from eight ground-based measurement stations operated by the South Florida Water Management District. The model allows almost continuous areal estimation of daily or hourly insolation at resolutions suitable for small-scale hydrologic modeling. Model estimates are comparable to measured values at ground stations and superior to estimates derived from interpolating between ground stations.

Urbanization 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...
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.

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.
