Abstract:
This thesis describes a generic approach for automated land cover monitoring. Knowledge about land cover is acquired through a knowledge acquisition exercise and used to augment image analysis in order to determine land cover change direction. It is demonstrated that taking a task-oriented approach to the change problem avoids the specificity of more traditional data-oriented approaches. The approach described here involves four key analyses that have contributed to the overall problem solution: Identifying the knowledge used to determine different land cover elements (elicitation and modellin

Abstract:
Throughout the years, land use and land cover (LULC) changes have directly impacted the water cycle in Iowa. To better understand the hydrological response to LULC change, the Hydrological Simulation Program - FORTRAN (HSPF) model will be used to qualitatively evaluate the effects of different LULC’s and quantify the associated adjustments to model parameters. Anecdotal and observational evidence of the hydrologic response will be employed to define how model parameters should be adjusted to represent certain LULC changes. The hydrologic assessment will be of the Turkey River Watershed located

Abstract:
Underlying the majority of remotely-sensed data analysis is the assumption that geographical phenomena, such as rivers, heather-moors and the dynamics associated with such objects, can be adequately detected and identified through the use of spectral and other visual information alone. There is a common misconception that any major deficiencies of quantitative analyses are "hardware problems": that by increasing the spectral, spatial, radiometric and temporal resolutions of sensors, geographical phenomena will be identified with similarly increasing accuracy and reliability. This, however, is

Tropical deforestation is one of the most important drivers of biodiversity loss and carbon emissions. This thesis seeks to analyse the dynamics of tropical deforestation and develop a probabilistic model that predicts land cover change (LCC) in the tropics. The main findings from the analysis of the Brazilian Amazon deforestation dynamics are that large clearings comprised progressively smaller amounts of total annual deforestation while the number of smaller clearings remained unchanged over time. These changes were coincident with the implementation of conservation policies by the governmen

Earth observation satellites (EOS) such as Landsat provide image datasets that can be immensely useful in numerous application domains. One way of analyzing satellite images for land use and land cover change (LULCC) is time series analysis (TSA). Several algorithms for time series analysis have been proposed by various groups in remote sensing; more algorithms (that can be adapted) are available in the general time series literature. However, in spite of an abundance of algorithms, the choice of algorithm to be used for analyzing an image stack is presently an open question. A concurrent is

Abstract:
Rapid urban growth and unprecedented rural to urban transition, along with a huge population growth are new phenomena for both high and low income countries, which started in the mid-20th century. However, urban growth rates and patterns are different in developed countries and developing ones. In less developed countries, urbanization and rural to urban transition usually takes place in an unmanaged way and they are associated with a series of socioeconomical and environmental issues and problems. Identification of the city growth trends in past decades can help urban planners and managers to

Abstract:
Este trabalho apresenta a base matemática do modelo chamado Autômatos Celulares Aninhados (Nested-CA), um modelo de computação destinado ao desenvolvimento de modelos de mudança de uso e cobertura do solo em múltiplas escalas. As principais propriedades do modelo nested-CA são descritas e comparadas aos modelos de computação baseados em agentes e em autômatos celulares. O modelo nested-CA foi implementado em uma ambiente computacional, chamado TerraME, que oferece uma linguagem de alto nível para a descrição de modelos, um conjunto de estruturas de dados espaço-temporais para a representação e
