Guía práctica para generar y mejorar topografías satelitales con el software “Global Mapper” enfocado al diseño vial

Abstract

The academic community of the civil engineering career, when generating and obtaining satellite topographies for road projects are unaware of tools, support materials that provide certain type of solution, this fact confirms that the Global Mapper software is wasted due to lack of knowledge. A guide to this software provides the student with an accessible and useful tool with information that enhances each of its functions when generating satellite topographies of any part of the world. The present practical guide of handling for the software "Global Mapper", is developed by means of the formulation of schematic steps with graphs and their respective descriptions so that the user has a greater understanding, achieves the obtaining of satellite topographies. This methodology includes useful infographics to describe each step. Three interfaces were used for the execution of the project, Google Earth, Global Mapper and Civil 3D in a complementary way, demonstrating their contribution and functionality to obtain the expected result. Consistent with the introduction to the interface, definitions and functionality of each one of its commands making its interpretation accessible, results in the elaboration of the guide to generate and obtain topographies focused on a road project, concluding in the execution, The Global Mapper software is postulated as an agile and didactic alternative to obtain satellite topographies, emphasizing that as a result of the research project it can be concluded that the Global Mapper software can be used for a pre-feasibility stage in a road design project, but it cannot be effective for the definitive design stage since it has a margin of error in altitude in terrains of high altitude, but it can not be effective for the definitive design stage since it has a margin of error in altitude in terrains of low altitude. margin of error in altitude in mountainous terrain.
