Resumen
En el presente trabajo final de graduación se realizó el análisis comparativo entre tres procedimientos de cálculo que permiten realizar el ajuste de redes topográficas o geodésicas en función de las observaciones convencionales realizadas, donde uno de los procedimientos comprende el análisis tridimensional (X, Y, Z), otro un análisis bidimensional (X, Y) y el último un análisis unidimensional (2). Las observaciones se realizaron con una estación total Leica TCR305, en una red de 16 puntos localizada en Santo Domingo de Heredia, Costa Rica, que pertenece a una red de densificación del Catastro Nacional, donde por su tipo de materialización (placas de aluminio fundido empotrado en concreto), ubicación y configuración, se logra obtener una rigidez y consistencia en la red para la comparación y análisis de los procedimientos de ajuste. Los procedimientos de cálculo o programas en este caso, los cuales realizaron los ajustes bidimensional y unidimensional ya están presentes en el mercado nacional e internacional. La Escuela de Topografía Catastro y Geodesia de la Universidad Nacional tiene licencia del programa de ajuste ARGE0, elaborado por la Consultora Cuatro S.R.L, que permite realizar el ajuste bidimensional y unidimensional. En el caso del ajuste tridimensional no se presenta programas conocidos que puedan realizar este proceso de cálculo utilizando observaciones obtenidas mediante métodos convencionales solo existen programas los cuales realizan estos ajustes pero en función de observaciones GPS como lo son el programa TGO (Trimble Geomatics OfficeTM) y Columbus. Por lo tanto, en este trabajo de graduación se decide realizar un programa de ajuste de carácter tridimensional con base a la literatura y deducciones matemáticas ya definidas, en función de observaciones convencionales y de esta manera obtener un resultado para la comparación con los otros dos ajustes.
In the present final graduation work, a comparative analysis was carried out between three calculation procedures that allow the adjustment of topographic or geodesic networks based on the conventional observations made, where one of the procedures includes the three-dimensional analysis (X, Y, Z ), another a two-dimensional analysis (X, Y) and the last one a one-dimensional analysis (2). The observations were made with a Leica TCR305 total station, in a 16-point network located in Santo Domingo de Heredia, Costa Rica, which belongs to a National Cadastre densification network, where due to its type of materialization (embedded cast aluminum plates specifically), location and configuration, it is possible to obtain a rigidity and consistency in the network for the comparison and analysis of the adjustment procedures. The calculation procedures or programs in this case, which made the two-dimensional and one-dimensional adjustments are already present in the national and international market. The School of Cadastre and Geodesy Topography of the National University has a license for the ARGE0 adjustment program, developed by Consultora Cuatro S.R.L, which allows for two-dimensional and one-dimensional adjustment. In the case of the three-dimensional adjustment, there are no known programs that can perform this calculation process using observations obtained by conventional methods, there are only programs that perform these adjustments but based on GPS observations, such as the TGO program (Trimble Geomatics OfficeTM) and Columbus. Therefore, in this graduation work it is decided to carry out a three-dimensional adjustment program based on the literature and already defined mathematical deductions, based on conventional observations and in this way obtain a result for comparison with the other two adjustments. .
