No. of bitstreams: 1 2300.pdf: 6404032 bytes, checksum: e8ddeb3d63aa24d2f243dee3d1114c99 (MD5) Previous issue date: 2007-12-20 / Atulim (2002) and Racanicchi (2003) had planned and implemented a geodetic GPS network in São Carlos city, which needed maintenance and revision. The proposals of this dissertation had consisted of: i) to bring up to date the GPS geodetic network in the city of São Carlos and to make it compatible with the SIRGAS2000 (Geocentric Reference System of Americas 2000), with new network adjustment and injunction in two geodesic vertices in the urban area of São Carlos, homologated by the IBGE after the implantation of the original geodetic network in 2003; ii) to evaluate and to compare the new results of the geodetic network coordinates obtained with the relative positioning through the tracking of artificial satellites, according to technology NAVSTAR/GPS and adjusted through the Least Squares Method, with results of coordinates obtained through the Precise Point Positioning (PPP) Method, processed by PPP on-line services. Analyzing the results obtained in this dissertation, it was possible to evaluate that the application of PPP Method, since that followed the specific orientations of each on-line service used, takes care perfectly to the required to support of cadastral registry and location services for the most varied purposes, however it does not substitute yet other services that demand highest degree of accuracy only obtained with vectors and network adjustment with statistical control of processes that demand high computational activity. / Atulim (2002) e Racanicchi (2003) planejaram e implantaram uma rede geodésica GPS no município de São Carlos, que necessitou de manutenção e revisão. As propostas desta dissertação consistiram em: i) atualizar a rede geodésica GPS no município de São Carlos e compatibilizá-la com o SIRGAS2000 (Sistema de Referência Geocêntrica das Américas 2000), com novo ajustamento da rede geodésica e injuncionamento em dois vértices geodésicos na área urbana de São Carlos, homologados pelo IBGE após a implantação da rede geodésica original; ii) avaliar e comparar os novos resultados das coordenadas da rede geodésica de São Carlos obtidas com posicionamento relativo através do rastreamento de satélites artificiais, segundo a tecnologia NAVSTAR/GPS (Navigation Satellite Timing and Ranging/Global Positioning System) e ajustadas através do Método dos Mínimos Quadrados (MMQ), com os resultados das coordenadas obtidas através do Método de Posicionamento Pontual Preciso (PPP), processadas por serviços de cálculo de PPP on-line. Analisando os resultados obtidos nesta dissertação, foi possível avaliar que a aplicação do Método PPP, desde que seguidas as orientações específicas de cada serviço on-line utilizado, atende perfeitamente à exigência requerida para apoiar serviços de cadastro e locação para as mais variadas finalidades, porém não substitui ainda outros serviços que demandam alto grau de exatidão conseguidas somente com vetores e ajustamento de rede com controle estatístico de processos que demandam alta atividade computacional.

APLICAÇÃO DA TRANSFORMAÇÃO ORTOGONAL NO GEORREFERENCIAMENTO COM DIVISÃO DE ÁREA / APPLICATION OF THE ORTHOGONAL TRANSFORMATION IN GEORREFERENCIAMENTO WITH PARTITION OF AREAS

Brum, Fabiano Becker 11 November 2008 (has links)
Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / The Geodesy methods and equipments progress brings with himself the growing need on geodetic surveys. Thereby, it is possible to make compatible any surveys with no extension boundary like from plane models and with no points overlap. These surveys are usually from geodetic satellites for that specific purpose. However, there are cases under precision restriction by nature of these systems, as well as physical conditions lack and equipments deficiency disables such operations. Thus, it becomes necessary to take place surveys from a topographical origin to a geocentric origin. To other cases, it is not enough just to know the geodetic coordinates but it is necessary to know its equivalent ones in the topographical plan, mostly to section and calculus of areas besides point locations. In these cases a solution of great use is the transformation of the geocentric coordinates to the UTM Projection plane cartographic coordinates, usually being ignored the deformations. Therefore it is a mistaken solution. Among the appropriate solutions to transform coordinates between surfaces from a topographical origin to a geocentric origin it is the Orthogonal Transformation. This method is more concise than the traditional Puissant´s methodology and to make possible the conversion of topographical coordinateds to geocentric coordinates and vice-versa. In this work the precision of Orthogonal Transformation method was compared initially with the Puissant´s method. Also were compared the differences among areas calculated from the UTM cartographic plan coordinates and topographical coordinates, besides having established the position discrepancy among boundary points calculated in a certain plan and implanted in other one without the true conversions. The results shows that the Orthogonal Transformation method precision is equivalent to Puissant´s method for observed ranges. It was possible to note that the values to areas calculated from coordinates related to models or different surfaces presents discrepancy. The areas section and estimation from the UTM cartographic projection plane coordinates, even with scale factor and elevation corrections, has been different to the area from the local topographical plan, although it was similar when under corrections. Points from section of geodetic areas can not to have implant in the topographical plane under use of UTM cartographic projection plane coordinates due to the position difference between it and the topographical coordinates. The more appropriate solution, due to good precision and easiness to section and estimate geodetic areas from geocentric coordinates, is the change to topographical ones using the Orthogonal Transformation. The Orthogonal Transformation of Coordinates is a practice and quick solution to make geodetic points from topographical surveys as well as to plot geodetic points in the topographical plan, and it is possible to implement it in the Electronic Total Stations in a easy way. / O avanço da geodésia, em seus métodos e equipamentos traz consigo a crescente necessidade da realização de levantamentos georreferenciados. Assim é possível compatibilizar vários levantamentos sem limites de extensão impostos pelo modelo plano e sem a sobreposição de pontos. Estes levantamentos geralmente são executados pelo rastreio de satélites que operam para este fim. Contudo, em certos casos as limitações de precisão e acurácia impostos pelos princípios destes sistemas, bem como a falta de condições físicas e deficiência de equipamentos impossibilita tal operação. Torna-se necessário então realizar levantamentos com a origem topocêntrica e transforma-la em geocêntrica. Em outros casos, não basta conhecer somente as coordenadas georreferenciadas, sendo necessário conhecer suas equivalentes no plano topográfico, principalmente para calcular e dividir áreas e implantar pontos no plano local. Nestes casos uma solução de grande utilização é transformação das coordenadas elipsoidicas geocêntricas em coordenadas planas associadas ao plano da Projeção Cartográfica UTM, geralmente ignorando-se as deformações, portanto consistindo em uma solução equivocada. Entre as soluções adequadas para a conversão de coordenadas de uma superfície para outra quando a origem dos sistemas difere entre topocêntrica e geocêntrica é a Transformação Ortogonal. Este método, além de ser mais sucinto que a metodologia de Puissant tradicionalmente utilizada permite a conversão tanto de coordenadas topocêntricas em geocêntricas bem como o inverso. Neste trabalho inicialmente se comparou a precisão do método da Transformação Ortogonal com o método de Puissant. Também foram comparadas as diferenças entre áreas calculadas apartir de coordenadas no plano cartográfico UTM e coordenadas topocêntricas, além de estabelecida a diferença de posição entre pontos de divisa calculados em um plano e implantados em outro sem as devidas conversões. O resultados obtidos demonstraram que a precisão do método de Transformação Ortogonal nas distancias observadas equivale com a metodologia de Puissant. Foi possível observar que os valores referentes a áreas quando calculadas em relação a coordenadas associadas a modelos ou superfícies diferentes apresentam variação. O cálculo e divisão de áreas utilizando coordenadas planas no plano da projeção cartográfica UTM, mesmo com correções de fator de escala e elevação diferiu da área no plano topográfico local, embora tenha se aproximado quando efetuadas correções. Pontos de divisão de áreas georreferenciadas não devem ser implantados no plano topográfico local utilizando-se coordenadas planas no plano da projeção cartográfica UTM, pois existe diferença de posição entre estas e as coordenadas topográficas. A solução mais adequada pela precisão e facilidade para cálculo e divisão de áreas georreferenciadas a partir de coordenadas geocêntricas é a conversão destas para topocêntricas pela transformação ortogonal de coordenadas. A transformação ortogonal de coordenadas constitui-se de uma solução prática e rápida tanto para o georreferenciamento de pontos oriundos de levantamentos topográficos, bem como para implantação de pontos georreferenciados no plano topográfico local, podendo ser inclusive facilmente implementado em estações totais topográficas.

In order to achieve the general objective, the work was done systematically in three stages which consisted the specific objectives. The first stage was the implementation of geodetic reference infrastructure for carrying out the geodetic survey of the study area. This process included the implementation of RGLS (Northern Coast of the RN GPS Network), consisting of stations with geodetic coordinates and orthometric heights of precision; positioning of Benchmarks and evaluation of the gravimetric geoid available, for use in GPS altimetry of precision; and development of software for GPS altimetry of precision. The second stage was the development and improvement of methodologies for collection, processing, representation, integration and analysis of CoastLine (CL) and Digital Elevation Models (DEM) obtained by geodetic positioning techniques. As part of this stage have been made since, the choice of equipment and positioning methods to be used, depending on the required precision and structure implanted, and the definition of the LC indicator and of the geodesic references best suited, to coastal monitoring of precision. The third step was the seasonal geodesic monitoring of the study area. It was defined the execution times of the geodetic surveys by analyzing the pattern of sediment dynamics of the study area; the performing of surveys in order to calculate and locate areas and volumes of erosion and accretion (sandy and volumetric sedimentary balance) occurred on CL and on the beaches and islands surfaces throughout the year, and study of correlations between the measured variations (in area and volume) between each survey and the action of the coastal dynamic agents. The results allowed an integrated study of spatial and temporal interrelationships of the causes and consequences of intensive coastal processes operating in the area, especially to the measurement of variability of erosion, transport, balance and supply sedimentary over the annual cycle of construction and destruction of beaches. In the analysis of the results, it was possible to identify the causes and consequences of severe coastal erosion occurred on beaches exposed, to analyze the recovery of beaches and the accretion occurring in tidal inlets and estuaries. From the optics of seasonal variations in the CL, human interventions to erosion contention have been proposed with the aim of restoring the previous situation of the beaches in the process of erosion. / O objetivo geral desta Tese de Doutorado foi o monitoramento costeiro sazonal (em escala temporal trimestral) de ?reas costeiras e estuarinas de um trecho do Litoral Setentrional do Estado do Rio Grande do Norte, Brasil, sens?vel ambientalmente e de intensa eros?o sedimentar sob as atividades petrol?feras, para servir de base na implanta??o de projetos de conten??o da eros?o e na mitiga??o dos impactos causados pela din?mica costeira. Para atingir o objetivo geral, o trabalho foi desenvolvido de maneira sistem?tica em tr?s etapas, as quais consistiram os objetivos espec?ficos. A primeira etapa foi da implanta??o da infraestrutura geod?sica de refer?ncia para a realiza??o dos levantamentos geod?sicos da ?rea de estudo. Compreendeu a implanta??o da Rede GPS do Litoral Setentrional do RN (RGLS), constitu?da de esta??es com coordenadas geod?sicas e altitudes ortom?tricas de precis?o; posicionamento de Refer?ncias de N?vel (RN) e avalia??o do modelo geoidal gravim?trico dispon?vel, para serem utilizados na altimetria por GPS de precis?o; e desenvolvimento de aplicativos para a altimetria por GPS de precis?o. A segunda etapa foi do desenvolvimento e aperfei?oamento de metodologias para o levantamento, processamento, representa??o, integra??o e an?lises de Linhas de Costa (LC) e Modelos Digitais de Eleva??o (MDE) obtidos por t?cnicas geod?sicas de posicionamento. Incluiu desde a escolha dos equipamentos e m?todos de posicionamento a serem utilizados, em fun??o da precis?o requerida e da estrutura implantada, at? a defini??o do indicador de LC e dos referenciais geod?sicos mais adequados ao monitoramento costeiro de precis?o. A terceira etapa foi do monitoramento geod?sico sazonal da ?rea de estudo. Definiu as ?pocas de execu??o dos levantamentos geod?sicos, a partir da an?lise do padr?o de din?mica sedimentar da ?rea de estudo; execu??o dos levantamentos, com os objetivos de calcular e localizar ?reas e volumes de eros?o e acres??o (balan?os sedimentares areal e volum?trico) ocorridas nas LC e nas superf?cies das praias e ilhas ao longo do ano, e estudo das correla??es entre as varia??es mensuradas (em ?rea e volume) entre os levantamentos e a atua??o dos agentes din?micos costeiros. Os resultados permitiram um estudo integrado das rela??es espaciais e temporais das causas e consequ?ncias dos intensos processos costeiros atuantes na ?rea, especialmente com a mensura??o da variabilidade da eros?o, transporte, balan?o e suprimento sedimentares ao longo do ciclo anual de constru??o e destrui??o das praias. Nas an?lises dos resultados, foi poss?vel identificar as causas e consequ?ncias da intensa eros?o costeira nas praias expostas, analisar a recupera??o sedimentar das praias e a acres??o nos canais de mar? e nos estu?rios. A partir da ?tica das varia??es sazonais das linhas de costa, interven??es antr?picas de conten??o de eros?o foram propostas com o objetivo de recuperar a situa??o anterior das praias em processo de eros?o.

In the P3-convexity, we present results on the P3- hull number on the Cartesian product, strong product and lexicographic product of graphs. In special, regarding to the Cartesian product, we proved a complexity result, in which we show, given a graph G resulting of a Cartesian product of two graphs and a positive integer k, is NP-complete to decide whether the P3-hull number of G is less than or equal k. We also consider the P3-hull number on complementary prisms GG of connected graphs G and G, in which we show a tighter upper bound than that found in the literature. In the geodetic convexity, we show results of the hull number on complementary prisms GG when G is a tree, when G is a disconnected graph and when G is a cograph. Finally, we also show that in the geodetic convexity, the hull number on the complementary prism GG is unlimited on connected graphs G and G, unlike what happens in the P3-convexity / Nesta dissertação, consideramos o parâmetro número envoltório em duas convexidades em grafos, a convexidade P3 e a convexidade geodética. Na convexidade P3, obtivemos resultados do número envoltório P3 para o produto Cartesiano, produto forte e produto lexicográfico de grafos. Em especial, em relação ao produto Cartesiano, obtivemos um resultado de complexidade, no qual mostramos que, dado um grafo G, resultante de um produto Cartesiano de dois grafos e um inteiro positivo k, é NP-completo decidir se o número envoltório P3 de G é menor ou igual a k. Também consideramos o número envoltório P3 para prismas complementares GG de grafos G e G conexos, em que mostramos um limite superior um pouco mais justo do que o encontrado na literatura. Na convexidade geodética, mostramos resultados do número envoltório para prismas complementares GG quando G é uma árvore, quando G é um grafo desconexo e quando G é um cografo. Por fim, também mostramos que na convexidade geodética o número envoltório do prisma complementar GG pode ser ilimitado para grafos G e G ambos conexos, diferentemente do que ocorre na convexidade P3.

Desenvolvimento de metodologia de cartografia digital para a recuperação de divisas de imóveis rurais através de escrituras e memoriais antigos. / Development of methodology of digital cartography for the recovery of verge of country property through old technical description.

Adilson Haroldo Piveta 10 April 2007 (has links)
Esta dissertação de mestrado propõe técnicas de Cartografia Digital para um melhor embasamento técnico do Estado na defesa do patrimônio imobiliário estadual em ações judiciais que versem sobre questões relacionadas ao direito de uso e ocupação de terras públicas, em grande parte situadas em áreas de preservação ambiental e que resultam, muitas vezes, em indenizações milionárias contra o Estado. Segundo COSTA NETO (2006), a confusão que predomina na documentação da propriedade imobiliária em unidades de proteção integral favorece a ocorrência de ações ilegais e dificulta a resolução de conflitos, constituindo um dos principais obstáculos às ações governamentais para implantação e proteção dessas unidades. Favorece, ainda, a existência da denominada \"indústria das desapropriações\", por meio de uma corrida em busca de grandes somas de indenizações pelo poder público. Desta forma, torna-se fundamental a adoção de procedimentos técnicos que incorporem metodologias modernas de Cartografia Digital a fim de que possam ser compatibilizadas plantas, escrituras e memoriais descritivos antigos à bases cartográficas georreferenciadas e unificadas, a fim de agilizar trabalhos de defesa dos interesses do Estado, poupando o erário público de indenizações improcedentes. Para tanto, tomou-se como objeto de estudos a Reserva Florestal do Curucutú, imóvel do Governo do Estado de São Paulo, com características técnicas bastante diversificadas, e que bem serviu de paradigma para o estabelecimento e aplicação dos procedimentos nos demais imóveis. / This master thesis proposes techniques of Digital Cartography for the enhancement of the technical bases of the State in the defense of its real state patrimony in judicial actions regarding the issues related to the right of use and occupation of public lands, in great part located in areas of environmental preservation resulting, many times, in millionaire indemnifications against the State. According to COSTA NETO (2006), the predominant confusion on the real state property documentation in units of whole protection favors the occurrence of illegal actions and turns the conflicts resolution difficult, constituting one of the main hindrances to the governmental actions for the implementation and protection of those units. It favors yet the existence of the so called \"Power to Seize Industry\", through a rush in search of great sum of indemnifications by the Public Power. Therefore, it is of fundamental importance the adoption of technical procedures which incorporate modern methodologies of Digital Cartography so the plans can be compatible, deed and old descriptive memorials to cartographic bases geo-referred and unified, in order to streamline the work in defense of the State interests, saving the treasury from unsuitable indemnifications. For in such a way, the Forest Reserve of the Curucutú was overcome as object of studies, property of the Government of the State of São Paulo, with characteristics techniques sufficiently diversified, and that it served of paradigm for the establishment and application of the procedures in the excessively immovable ones well.

Geofyzikální metody začlenění lokálních výškových systémů do celosvětového výškového systému / Geophysical methods of integration of the local vertical datums into World Height System

Buday, Michal Unknown Date (has links)
One of the main problems of current physical geodesy is the unification of local height systems and the creation of the unified global vertical reference frame, whose primary definition constant will be the geopotential value of W0 on the level surface, such as geoid. This problem encounters several pitfalls, such as different types of physical heights used in the world, ways of eliminating the effects of tides on the shape of the Earth's body. The first parts of the thesis describe the theoretical foundations concerning the description of the Earth's gravitational field, the basics of height theory and the solution of the boundary value problems used in geodesy, together with the solution of the Hotine's and Stokes' integral by convolution. Due to the fact that the data of directly measured gravity acceleration for the territory of the Czechia and the Slovakia are not freely available with sufficient coverage, these data were replaced by gravity disturbances calculated from the Global Gravity Model of the Earth. To improve the data obtained from geopotential models, so-called residual terrain modelling was used. It is a spectral combination of gravity field models with relevant Earth's gravitational field quantities, which are obtained by modeling from a digital terrain model and a height model that represents the mean value of topography. The combination of these data consists of calculating those frequencies of the gravitational signal from the digital terrain model that are not a part of the signal obtained from geopotential models that in general have a lower spatial resolution. Two methods were used to connect the local height systems of the Czechia and the Slovakia. The first method was to use the solution of Molodensky's problem. The second method used is originally a method developed to test geopotential models. Both methods were tested on a set of measuring points (GNSS/levelling points).

Měření posunů a přetvoření mostu Gagarin / Deformation Measurement of Gagarin Bridge

Czíria, Kornél January 2016 (has links)
The work deals with a complex analysis of displacements and deformations of one bridge span of the railway bridge "Gagarin". The bridge structure was since 2009 annually measured. In addition to long-term monitoring of the bridge a 24-hour automatized monitoring was conducted in 2015 using robotic total station. The results of monitoring enables the analysis of displacements and deformations, analysis of measurement accuracy and also environmental influences on the structure - determination of the temperature dependence of deformations. Another part of the work is evaluating the long-term stability of the height reference frame that was used for geodetic epoch measuring of the bridge columns. The results of the work are the values of detected displacements and deformations, their graphical illustration, geometric interpretation and relevant characteristics of accuracy.

Kremser, Christian January 2013 (has links)
This thesis deals with testing of astronomical measurement system MAAS-1, which was developed at the Institute of Geodesy, Faculty of Civil Engineering, Brno University of Technology. Several reference measurements were done on the terrace of B building Faculty of Civil Engineering during this testing. The data obtained were processed into astronomical geographic coordinates and . These coordinates, as well as atmospheric conditions and calibration measurements, are basis for evaluation. In this test I try to detect the influence of the CCD sensor mounting of the accuracy on the final data and to assess if the construction needs to be modified.
