Sistema de recolección de datos topográficos para la construcción de curvas de nivel utilizando sistema de posicionamiento global

Abstract

Introduction— The construction of contour lines is a daily activity for topography, civil engineering and architecture, with these plans a survey of the information of the earth’s surface is carried out. For this process, theodolites are used, which manually go through a determined surface and take the different heights against a reference point. The introduction of electronic systems for data collection would allow this process to be carried out more quickly and efficiently.

Objective— For this reason, the development of a topographic data collection system that allows the construction of contour lines from a GPS receiver module is proposed.

Methodology— To achieve this goal, an experimental investigation was carried out that includes the theoretical review, followed by the design, the construction of the model, and the construction of the prototype with a validation of the results using descriptive statistics.

Results— In this way, a device capable of carrying out the survey of the topographic information necessary for the construction of the contour lines was obtained with a fairly low error in the shots.

Conclusions— The information from the global positioning system was obtained in NMEA0183 format from which the specific data necessary to store it was extracted and then delivered to the various software that is normally used for the construction of contour lines.
