Qplanner: Módulo para planejamento de voo no software Qgis

Abstract

Society evolves every day, as a result, the technological advance as well, allowing processes, techniques and analysis tools to develop ways to optimize processing. In this bias, there is cartographic production, where there is a need to create mechanisms that assist in the methodological procedures performed. Geotechnologies come as an instrument for optimizing this data, where, with each passing year, its methods and techniques are modernized, allowing operators to gain quality and precision in the work performed. One of these mechanisms comes from Remote Sensing, having the name Photogrammetry. Photogrammetry is considered a science that obtains information about terrestrial physical objects through the use of photographic images. In this sense, flight planning is one of the primary stages, as far as photogrammetric products are concerned, so that it must be well planned and executed. Thus, the objective of this work was to develop a flight planning module using the Quantum Gis Geographic Information System (QGIS) platform. QGIS and Python manuals, methods, and libraries were used to develop the module through code implementation, where we used Python-based programming techniques called PyQgis. From this, there is an experimental flight planning module designed for QGIS, where it requests the user the essential parameters for the calculations in an automated way, obtaining as products the fly area polygonal, the point cloud, where each point represents the central coordinate of the photograph taken during flight and the results of calculations of the variables required for flight planning. Given the results obtained by the module, the products and the time taken to generate them were compared with the mechanically performed operations. Concluding the great advantage of the module over the manual procedure, helping to save time and minimize the risk of gross errors.
