We present a numerical simulation method for designing geodetic networks. The quality criterion considered is based on the power of the test of data snooping testing procedure. This criterion expresses the probability of the data snooping to identify corr... see more

The densification of geodetic surveys using classical positioning techniques such as total stations may be necessary due to the quality of Global Navigation Satellite System (GNSS) positioning in urban canyons. However, the correction of distances and ang... see more

Models for processing geodetic observations made in support networks related to hydropower objectives are the ones used in general geodetic networks. For geodetic observations processing, based on the type of measurements made, are used mathematical model... see more

The development of Free Software is a well established and successful phenomenon which could hardly exist without the Internet, where groups of programmers scattered all around the world are developing software. The idea of Free Software is highly attract... see more

The observations in geodetic networks are measured repetitively and in the networkadjustment step, the mean values of these original observations are used. The meanoperator is a kind of Least Square Estimation (LSE). LSE provides optimal resultswhen rando... see more

There has been a need for geodetic network densification since the early days oftraditional surveying. In order to densify geodetic networks in a way that willproduce the most effective reference frame improvements, the crustal velocity fieldmust be model... see more

O monitoramento de movimentos da crosta utilizando, especificamente, técnicasgeodésicas constitui uma importante ferramenta para o controle e a segurança deestruturas naturais ou artificiais. O Sistema de Posicionamento Global tem sidoutilizado no estabe... see more

 
The present paper deals with the use of neural networks in the displacement and deformation fields modelling and analysis. The Generalized Regression Neural Network (GRNN) has proved its efficiency and reliability than the classical methods in the approxi... see more
