Resumen
En este trabajo, se ¡implementó el desarrollo de una metodología de nivelación, mediante mediciones convencionales realizadas con estación total, la cual se denomina poligonación vertical. El trabajo se realizó en la provincia de Heredia, en una red de 25 puntos vinculada a la Red Altimétrica Nacional mediante la inclusión de tres bancos de nivel oficiales, para un total de 28 nodos. Basados en esta red se realizaron itinerarios de nivelación aplicando la metodología propuesta, obteniendo entre otros datos la diferencia de nivel entre los puntos de la red así como la distancia horizontal recorrida en los itinerarios.
Los datos de campo obtenidos fueron sometidos a un proceso de ajuste geodésico mediante el programa de ajuste de redes geodesicas ARGE-DOGO®, hasta llegar a obtener la cota ajustada y referida al nivel medio del mar de cada uno de los puntos de la red.
Los resultados permiten demostrar que la metodología de poligonación vertical brindo una exactitud promedio de + 20mm en general para cada uno de los puntos de la red realizando el proceso de ajuste para toda la red y no por líneas independientes de nivelación. Finalmente, con los errores de los desniveles ajustados y de las longitudes de cada itinerario, se desarrolló un análisis de regresión lineal simple del cual se obtuvo una ecuación de regresión, capaz de estimar errores apriorísticos para itinerarios de nivelación a realizar con la metodología de poligonación vertical.
In this work, the development of a leveling methodology was implemented, through conventional measurements made with a total station, which is called vertical polygonation. The work was carried out in the province of Heredia, in a network of 25 points linked to the National Altimetry Network through the inclusion of three official level banks, for a total of 28 nodes. Based on this network, leveling itineraries were carried out applying the proposed methodology, obtaining, among other data, the difference in level between the points of the network as well as the horizontal distance traveled in the itineraries. The field data obtained were subjected to a geodetic adjustment process using the ARGE-DOGO® geodetic network adjustment program, until the adjusted elevation was obtained, referring to the mean sea level of each of the network points. The results allow to demonstrate that the vertical polygonation methodology provided an average accuracy of + 20mm in general for each of the points of the network, performing the adjustment process for the entire network and not by independent leveling lines. Finally, with the adjusted unevenness errors and the lengths of each itinerary, a simple linear regression analysis was developed from which a regression equation was obtained, capable of estimating a priori errors for leveling itineraries to be carried out with the polygonation methodology. vertical.
