REDEGEO: sistema digital para construção e gerenciamento de redes geodésicas

Abstract

In engineering, geodetic networks appear to solve problems in the areas of georeferencing, topographic surveys, locations, measurements in works, aerophotogrammetry, among other areas that require the use of georeferenced data. In Brazil, IBGE is the body responsible for the Geodetic Database, consisting of altimetry, gravimetry and planialtimetry networks. The platform works online, through searches for specific municipalities, RNs or geodesic landmarks, the user has access to reports with geospatial data and can download them. Access to the network-dependent platform makes it difficult for users to access data in the field. This work proposes a system for registration and management of geodetic networks with Offline First technology, that is, the application can work with or without internet. The system user registers and manages geospatial data for geodetic networks, the user can obtain the information of the stations that compose the networks through reports or their proper coordinates in real time on a digital map. The proposed system consists of a website developed in the PHP programming language for registration and management of geodetic networks, geodetic identifiers with unique QR-Code codes, geodetic database developed in MySQL and a native application for IOS / Android developed through Flutter Framework for viewing the geospatial information of the geodetic identifiers implanted on the Earth's surface. The vertices registered for this work make up the geodesic network of the Federal University of Pampa at Campus Itaqui-RS.
