1. A QUANTITATIVE EVALUATION OF DGPS PERFORMANCE IN THE POSITION AND PSEUDORANGE DOMAINS
Abstract: This study compares in quantitative terms two methods of differential corrections to GPS positioning from the code-based pseudoranges. The differential method calculated from the coordinates (Latitude, Longitude and Altitude), called Position-Domain DGPS, has simple implementation and easy transmission by the correction vector. The second method, c

2. Comparación de anomalías de gravedad derivadas de altimetría satelital con datos de gravedad marina en el margen continental Argentino
In this paper we address the comparison among grids from different altimetry-derived global gravity anomaly datasets with marine gravity anomalies from cruises in the Argentinian continental margin and adjacent oceanic areas in order to determine if there are significant differences among these data sources, particularly in areas near the coast where there a

3. A utilização de modelos geoidais e altimetria por satélite no estudo das variabilidades no nível do mar e correntes geostróficas no Atlântico Sul e região da Confluência Brasil Malvinas / On the use of geoidal models and satellite altimetry for studying the variabilities of sea level and geostrophic currents in the South Atlantic and Brazil Malvinas Confluence Region
A variação do nível do mar em relação ao geóide é conhecida como Topografia Dinâmica do oceano, cuja determinação é importante no estudo da circulação geostrófica, vórtices e outros fenômenos. O sinal do geóide predomina na definição da topografia dinâmica em todos os comprimentos de onda, ou seja, o nível do mar está intimamente ligado

4. Geotechnology applied to the sub-basin of the river and its environmental relationships Piauitinga / Geotecnologia aplicada à sub-bacia hidrográfica do Rio Piauitinga e suas relações ambientais
The complexity and challenges of using the sub-basin of the river Piauitinga were approached from the choice of methodology geosystem suited for small river basins based on diagnosis of geoenvironmental and socioeconomic conditions. The area under study includes the municipalities Lagarto, Boquim, Salgado and Estancia and making the area of 411.98 square km

5. Geotecnologias como contribuição ao estudo do agroecossistema cafeeiro de Minas Gerais em nível municipal / Geotechnologies as contribution to the study of coffee crop agro system at municipal level in Minas Gerais state
Coffee crop, an important economic and social activity to Brazil, is an agrobusiness segment that has not updated information about the agroecosystem and the productive profile. In this sense, it was proposed in the year of 2004 a multidisciplinary and multi institutional project, involving INPE, EMBRAPA and UFLA to characterize the coffee agroecosystem in M

6. Use of altimetry and images of satellite in the differentiation of forest types / Uso de altimetria e imagens de satÃlite na diferenciaÃÃo de tipos florestais
This work shows the auxiliary data integration to improve the differentiation of forest types with the digital classification of image of sensor ETM+ (Landsat 7). The auxiliary data are here compared with topography of the place. The study area is into a brejo de altitude and is located among the cities of Belo Jardim, Brejo da Madre de Deus e TacaimbÃ, in

7. THERMAL FIELD AND URBAN HEAT ISLANDS ESTUDY IN SANTA MARIA-RS / ESTUDO DO CAMPO TÉRMICO E DAS ILHAS DE CALOR URBANO EM SANTA MARIA-RS
The objective of this work was to analyze the thermal field and the urban heat islands in Santa Maria and its surroundings, relating their thermal and spatial behaviors throughout both urban and natural interaction, facing the imposition of types of weather originated from Prefrontal Phase and Polar Domain atmospheric conditions, during the winter. The Therm

8. Time variability of sea surface parameters in the tropical Atlantic using satellite and in situ data
The influence of the tropical Atlantic Ocean over the climate of Europe, Africa and America is well known today. However, several questions about high-frequency processes in this region remain open. This thesis addresses the characterisation of the diurnal and other short timescale variability of the meteo-ocean variables measured in the tropical Atlantic Oc
