Descripción
El principal objetivo de este trabajo ha sido la elaboración de un DSM implementando la tecnología VANT con el fin de comparar, analizar y evaluar los productos obtenidos.
Partiendo de la visita de campo identificando las instalaciones, posibles puntos de control y pista de aterrizaje para el DRON; continuando con el amarre geodésico con el posicionamiento del punto PL-01 materializado en las instalaciones de la sede tecnológica de la Universidad Distrital Francisco José de Caldas, implementado como base para el respectivo posicionamiento de los puntos de control; para la determinación de coordenadas se apoyó en la estación continua BOGT y el vértice 10-BGT con cota geométrica certificada.
Teniendo el amarre geodésico del proyecto se procede a la planeación de las rutas de vuelo y ejecución de los mismos implementando el software eMotion 2. Para el proceso de la información obtenida se implementaron los programas Postflight Terra 3D y Photoscan.
Finalmente los resultados obtenidos con cada programa se someten a una comparación en paralelo con las guías para la prueba de precisión proporcionados en la norma NTC 5205 y el documento ASPRS Positional Accuracy Standards For Digital Geoespatial Data (ed. 1 ver. 1.0 /nov 2014).
The main objective of this work was the development of a DSM implementing UAV technology to compare, analyze and evaluate the products obtained. Based on the field visit to identify the facilities, possible checkpoints and runway to the drone; Continuing the geodetic positioning mooring point with PL-01 materialized in the premises of the headquarters of the technological University Francisco José de Caldas, implemented as a basis for the respective positioning of the control points; for determining coordinates leaned on continuous station Bogt and vertex-10 BGT with certified geometric dimension. Given the geodetic tie the project proceed to the planning of flight routes and their execution implementing the software eMotion 2. To process the information obtained Postflight PhotoScan Terra 3D and programs were implemented. Finally the results obtained with each program are subjected to a comparison in parallel with the test guidelines for the accuracy provided in ISO 5205 standard and document ASPRS Positional Accuracy Standards For Digital Geospatial Data (ed. 1 Ver. 1.0 / November 2014).
