Diseño e implementación de una aplicación móvil Android para la navegación y aprovechamiento de la red geodésica del IGAC y conversión de coordenadas dentro del sistema Magna Sirgas

Abstract

The Geomatic works involves GNSS positioning and navigation system of the passive Instituto Geográfico Agustín Codazzi (IGAC) network. The system needs to identify the geographical location of each materialized point to obtain its coordinates and its respective geometric elevation. In the case of the active network, it implies knowing the distance from the closest station to the point of the topographic survey. A recurring problem is a poor signal in rural areas to consult IGAC open data information. Besides, consulting the tracking time according to different standards of institutional companies can be difficult if there was no planning work before going to the land work. It is important to have alternatives for these problems at a surveyor’s work. For this reason, we proposed to design and implement a mobile application for navigation and calculation of tracking times using the IGAC geodetic reference network and the conversion of coordinates in the MAGNA SIRGAS datum with three objectives: 1. Implement a module to navigation of points for the IGAC Passive network. 2. Design a module to determine tracking times by GNSS position system using the IGAC continuous tracking stations. 3. Develop a module that allows the conversion of coordinates in the MAGNA SIRGAS datum between Cartesian Plane Projections, Gauss Krüger Coordinates, Ellipsoidal Coordinates, Geocentric Coordinates, and the CTM12 UTM system.
