Vliv metody dotransformace zpřesněného rastru na přesnost katastrální mapy digitalizované / Influence of Up-Transformation Method of Improved Raster on Accuracy Digitalized Cadastral Map

Slowioczek, Lukáš January 2012 (has links)
Transformation of improved rastr is performed for digitalization of fathom cadastral maps, without analyzing in detail the risk arising from the number of identical items for the selected Up-transformation. The diplom’s thesis aims to analyze a influence of up-transformation used method to precision of improved rastr. Transformation of improved rastr was performed for chosen number of determination by Jungova, TPS and Block up-transformation. Agreement of improved raster and digital cadastral map was tested by the system of Kokeš. This test was conducted using checking points in the urban cadastral area.

No. of bitstreams: 1 Marcia Vieira.pdf: 3313448 bytes, checksum: d9dfb52d32be90e312d15a3cc127b227 (MD5) Previous issue date: 2008-11-10 / Secretaria da Educação do Estado de São Paulo / The object of the present paper is to study the interactions between the student and the environment of dynamic statistics, which, in this paper, will be the software Fathom, according to the approach of the Exploratory Data Analysis. We have discussed which concepts and procedures are necessary, aiming to the construction of critical analysis of a group of data, favored by the dynamism of the computational environment, which will be a tool to facilitate the mobilization of different types of registers of semiotic representations of this set. As theoretical reference, we have considered the levels proposed by Curcio (1989, 2001) to analyze the graphic comprehension mobilized by students in a situation of problem solving proposed in statistical context, and in the theory of Register of Semiotic Representation, by Duval (1994). We have tried, this way, to establish an understanding of this theory, largely used in researches in the Mathematics Education area relatively to geometric and algebraic concepts, this time to a representation of the statistics concept. We have especially tried to study the kinds of understanding of a picture, in this case, the kinds of understanding of statistical graphics or tables. In order to do so, we have elaborated a didactics sequence of activities developed with the use of the software, with bases on the Didactics Engineering (ARTIGUE, 1988). Before starting working with the activities of didactic sequence, we have realized a diagnostic test with the students, in which we were able to identify their main difficulties concerning statistical concepts. The development of the didactics sequence has shown that the interaction with the computerized environment and with the groups, in the articulations of different kinds of representation, have contributed to the comprehension of concepts as the arithmetic mean and median, and also with the analysis and interpretation of graphics of columns and dots (Dot-Plot). However, these variables are still insufficient to the comprehension of measures as quarts and the Box-Plot graphic / O presente trabalho tem como objetivo estudar as interações entre aluno e um ambiente de estatística dinâmica, que neste trabalho será o software Fathom, segundo a abordagem da Análise Exploratória de Dados. Discutimos quais os conceitos e quais os procedimentos necessários, visando à construção de uma análise crítica de um conjunto de dados, favorecida pelo dinamismo do ambiente computacional, que será uma ferramenta para facilitar a mobilização de diferentes tipos de registros de representações semióticas deste conjunto. Como referenciais teóricos, consideramos os níveis propostos por Curcio (1989, 2001) para analisar a compreensão gráfica mobilizada pelos alunos em situação de resolução de problemas propostos em contexto estatístico, e na teoria dos Registros de Representação Semiótica, de Duval (1994). Buscamos assim estabelecer uma leitura desta teoria, amplamente utilizada em pesquisas na área da Educação Matemática relativamente a conceitos geométricos e algébricos, dessa vez para a representação dos conceitos estatísticos. Buscamos especialmente estudar os tipos de apreensões de uma figura, no caso, os tipos de apreensões de um gráfico ou tabela estatística. Para tanto, elaboramos uma seqüência didática de atividades desenvolvidas com o uso do software, com base nos pressupostos da Engenharia Didática (ARTIGUE, 1988). Antes de iniciar o trabalho com as atividades da seqüência didática, os alunos realizaram um teste diagnóstico preparado por nós, em que pudemos identificar suas principais dificuldades em relação aos conceitos estatísticos. O desenvolvimento da seqüência didática mostrou que as interações com o ambiente informatizado e com os grupos, nas articulações dos diferentes tipos de representação, contribuíram com a compreensão de conceitos como a média aritmética e a mediana, e também com a análise e interpretação de gráficos de colunas e de pontos (Dot-Plot). No entanto, estas variáveis ainda foram insuficientes na compreensão de medidas como os quartis, e do gráfico Box-Plot
