Title: An evaluation of post-classification comparison for historical land information systems.
Creator: Roberts, Richard Scott., Florida Atlantic University, Roberts, Charles
Abstract/Description: The population of southeast Florida has grown considerably since the 1940's. Managing this population growth has challenged urban planners and growth managers. Prior to 1970, geographers and cartographers struggled with mapping this area as the landscape underwent rapid transformation to accommodate millions of new residents. With the launch of the Landsat satellite series in 1972, digital satellite images of southeast Florida have been acquired every 18 days to provide geographers and...
Show moreThe population of southeast Florida has grown considerably since the 1940's. Managing this population growth has challenged urban planners and growth managers. Prior to 1970, geographers and cartographers struggled with mapping this area as the landscape underwent rapid transformation to accommodate millions of new residents. With the launch of the Landsat satellite series in 1972, digital satellite images of southeast Florida have been acquired every 18 days to provide geographers and cartographers with a new tool for monitoring land use change. This thesis examines the utility of using this new tool combined with historical aerial photographs to document land use change through time.

Show moreThe South Florida Water Management District in conjunction with Florida Atlantic University began an effort to record vegetation invading Lake Okeechobee in 1994. This effort included a mapping project that would include all detectable vegetation within the expanding littoral zone. There were several problems associated with remote sensing aspects of this project. These problems resulted in inaccurate classification of species and a redundancy of mapping for large areas. This thesis will review the remote sensing methods used for the mapping project, analyze the associated errors within the map product, and lastly offer an alternative approach, incorporating the use of iterative remote sensing, for mapping the vegetation of Lake Okeechobee and other areas of complex vegetation.

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 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.

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 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.

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.

Show moreMany studies have been devoted to investigating the process by which individuals make dispositional attributions about the people that they encounter. Typically, individuals are more likely to seek future interactions with target individuals if those target individuals have a positive or rewarding disposition. Interactions with target individuals possessing negative or punishing dispositions reduce the likelihood that target individual will be selected for future interactions. An initial false positive trait ascription will be self-correcting with future interactions. An initial false negative trait label will likely remain stable if future interactions are not forced. The importance of quick accurate disposition identification carries important evolutionary implications as well as normal-life implications. Results from an experiment support the ability of subjects to accurately identify the true trait of target individuals with limited dispositional information.

In the first study, participants were shown gestures for tools corresponding either to tool design, or to the physical affordances of a puzzle designed for each tool. In the second study, two additional conditions were added. In the first, gestures were used that did not correspond to tool design or the puzzle affordances. The second was a control condition in which no gestures were shown. Results indicate that the demonstration of gestures appropriate to a novel problem situation facilitate creative use of tools. Additionally, attention to tool and puzzle affordances is effective for creative tool use when no gestural input is present. However, knowledge of tool design may interfere with this creative application. Performance is further hindered by the demonstration of gestures consistent with tool design, which may prime individuals to rely on the design stance.

Juvenile green sea turtles from the near shore reefs of Palm Beach County, Florida were brought to the lab to determine whether the sun could serve as a visual orientation cue. When tethered during the day in a large outdoor tank west of the ocean, the turtles oriented east to northeast. To determine whether the sun's position was used to maintain their heading, I altered the turtles' perception of time by entraining them to a light cycle advanced by 7 h relative to the natural cycle. When tested afterward in the same outdoor tank the turtles oriented northwest, the predicted direction after compensating for the sun's movement over 7 h across the sky. Orientation was unchanged when the turtles bore magnets that negated the use of magnetic cues. These results are consistent with the hypothesis that the turtles used the sun for orientation.

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.

Show moreHigh-resolution imagery is becoming readily available to the public. Private firms and government organizations are using high-resolution images but are running into problems with storage space and processing time. High-resolution images are extremely large files, and have proven cumbersome to work with and control. By resampling fine resolution imagery to a lower resolution, storage and processing space can be dramatically reduced. Fine-resolution imagery is not needed to map most features and resampled high-resolution imagery can be used as a replacement for low-resolution satellite imagery in some cases. The effects of resampling on the spectral quality of a high-resolution image can be demonstrated by answering the following questions: (1) Is the quality of spectral information on a color infrared DOQQ comparable to SPOT and TM Landsat satellite imagery for the purpose of digital image classification? (2) What is the appropriate resolution for mapping surface features using high-resolution imagery for spectral categories of information? (3) What is the appropriate resolution for mapping surface features using high-resolution imagery for land-use land-cover information?

He/she is familiarized with the user interface of each package, through detailed step-by-step methodology. Positional accuracy of each product is compared to Ground Control Points (GCPs) derived from a Differential Global Positioning System (DGPS). The accuracy of each product is also compared to the industry standard USGS DOQQ, and it is discovered that while simple rectification procedures may produce mean errors acceptable to the specifications of NMAS, the strictest application of these standards reveal that these products are not accurate enough to satisfy the USGS standards.

The Forestry Division of St. Vincent island has minimum resources and the island's topography varies from sea level to 1,324 meters. The plight of the endemic, endangered St. Vincent Parrot (Amazona guildingii) was used as a case study. An appropriate habitat monitoring technique was formulated for the Forestry Division so that it may better conserve the species. This technique employs 57 meter resolution imagery and the IDRISI software package. The resulting classification maps areas of habitat versus non-habitat. This technique of low cost, vegetation cover mapping can be used for many natural resource planning and interpretation applications throughout the Caribbean.

Show moreNormal color digital ortho-photos with six inch resolution were used to test the feasibility of mapping the habitat of the Florida apple snail, the exclusive food source of the Endangered Florida snail kite. Several remote sensing techniques such as unsupervised and supervised classifications are evaluated and accuracy assessed. While the overall ability to classify apple snail habitat is significant, sparse areas of emergent vegetation which are preferred foraging areas for the kite were excluded by the classification and needed to be re-introduced for further analysis. The methodology can be repeated to measure change over time since the NC imagery of Grassy Waters Preserve is acquired frequently. Additionally, three spectral levels of density abundance of wetland graminoid species that denote apple snail habitat were examined for mapping potential on the imagery. A site suitability analysis using a weighed overlay tool in ArcGIS is suggested as a means to include numerous other key factors influencing habitat selection by the snail kite in a mapping project.
