1. Mapeamento dos aspectos hidrogeoquímicos de águas subterrâneas a partir de estatística multivariada e redes neurais artificiais
RESUMO O objetivo central deste trabalho foi realizar o mapeamento dos aspectos hidrogeoquímicos de águas subterrâneas usando a estatística multivariada e redes neurais artificiais como subsídio para identificação de padrões espaciais. Para tal, foi executado um estudo de caso em aquíferos no município de Lençóis, Bahia, na região da Chapada Dia

2. Horizontal and vertical positional accuracy assement of cartographic products of the amazon region derived from interferometric sar data in X and P bands from ORBISAR sensor / Avaliação da acurácia posicional planialtimétrica de produtos cartográficos da Região Amazônica extraídos de dados SAR interferométricos nas bandas X e P do sensor ORBISAR
The Geographic Service of the Brazilian Army (DSG) is running a major mapping project in Brazil, called ´´Radiography Amazon", the region known as ´´Empty Mapping the Amazon." This area, approximately 1,8 million km$^2$, has not had, to date, appropriate land information mapping at scales larger than 1:250,000, except insufficient cartographic documents

3. COMPARAÇÃO DE PROCEDIMENTOS PARA A INTEGRAÇÃO DE LEVANTAMENTOS TOPOGRÁFICOS E LEVANTAMENTOS COM GPS / COMPARISON OF PROCEDURES FOR THE INTEGRATION OF TOPOGRAPHICAL SURVEYS AND GPS SURVEYS
The georeferencing consists of the description of the rural property, characteristics and confrontations, of descriptive memorial containing the border coordinates, georeferenced to the Brazilian Geodetic System following the positioning precision defined by INCRA. The perimeter survey of a rural property can be done only using GPS receivers, or only with to

4. Influência da geometria dos satélites na precisão das coordenadas geodésicas obtidas com o sistema GPS / Influence of satellite geometry on the geodetic coordinates precision from GPS determinations
The obtaining precision of GPS (Global Positioning System) surveying depends on of many factors, due the several error fonts. In general, these interferences can be modeled and considerations are made as each one contributes. In the beginning of the positioning systems, the mission planning was essential to find the period of the day that would possible to h

5. Irregular polygon partitioning on the biaxial ellipsoid on the surface of the Lambert azimuthal equal-area projection / DIVISÃO DE POLÍGONOS IRREGULARES DO ELIPSÓIDE BIAXIAL NA SUPERFÍCIE DA PROJEÇÃO AZIMUTAL EQUIVALENTE DE LAMBERT
This dissertation supplies the methodology of the measure (area) in the Earth model adopted for Geodesy. This model is the ellipsoid of revolution, in which the system of Cartesian coordinates, the curvilinear coordinate system and the polar coordinate system are described. The coordinate nature in the development of the surface measure calculation is discus

6. AJUSTAMENTO E CONTROLES DE QUALIDADE DAS LINHAS POLIGONAIS / LEAST-SQUARES ADJUSTMENT METHOD AND QUALITY CONTROLS OF TRAVERSES
Brazil is a country of great dimension that still holds unexplored areas of little population nowadays. Actually these lands are state-owned, but they have been appropriated as a private property, especially in the Amazon basin. The need for a governmental more effective territorial management was formally implemented through the establishment of a geodetic

7. ANÁLISE DA QUALIDADE DE RESULTADOS GPS EM PROGRAMAS COMERCIAIS / QUALITY ANALISYS OF GPS RESULTS IN THE COMMERCIAL SOFTWARE
The Brazilian technician-scientific community that dedicates to the surveying is living a new time with the normatization of the technical parameters for reference of the geodesic surveys to Cadastro Nacional de Imóveis Rurais according to Brazilian Law 10.267/2001. The objective of this work is to analyse by means of the statistical parameters the quality

8. DeterminaÃÃo e remoÃÃo de erros em mapas de colheita de milho
The automation of the the monitorated harvest ends introducing systematic errors to the process, for this reason, a methodology of filtering of data became necessary for obtaining confident maps and it treats about the mean error factor, which is the delay time. The delay time is that spent between the cutting of the plant by the platformâs bar and the pass

9. Estudo das distorÃÃes do sistema geodÃsico de referÃncia da regiÃo metropolitana do Recife / Study of the distortions of the geodesic system of reference of the region metropolitan of Recife
This work came out in the course of the need of determination o possible distortions found in the Geodesic System of Reference of the Metropolitan Region of Recife (MRR), implemented in 1973. So that the main objective of this work is to analyze the existing discrepancies into MRR in order to help the users to understand the discrepancies in the Geodesic Net
