Método de la supervisión de la interventoría para verificación de los perímetros catastrales a través de la Tecnología DRONE y la Fotogrametría en un lote a intervenir para el desarrollo del proyecto Centro Oncológico FOSUNAB

Abstract

The different advances in the technological tools of the disciplines of Surveying and Photogrammetry through DRONEs have been gigantic advances that have largely permeated all human activities. The technological advances of Topography and photogrammetry and their relationship with the activity of the Audit Office is no exception to the rule, from tape measurements, through theodolite and the level of precision, this has evolved until reaching the total station. as a fundamental element of the topographic process, and subsequently the integration of more sophisticated and precise tools such as DRONEs, geolocated aerial photogrammetric samples and their post-processing through digital editing and photointerpretation make cartography, topography and measurement processes and control of works, buildings, roads from the audit becomes more efficient and effective in many ways. The present work of technical report, I apply a method of verifying the perimeters of properties to intervene with civil works through the compendium of a series of post-processing protocols of images obtained with DRONE technology and various Photogrammetry software and the fusion of points of high-precision terrestrial control, generating the development of cartographic information and the development of the photointerpretation of a property that will be intervened with the construction of an oncology center, thus determining through this document the reliability of said topographic and photogrammetric methods that improve the conditions of verification of the surveying of a property and therefore configures the use of the tool of DRONEs and the discipline of photogrammetry, as essential as this precision tool becomes an instrument that facilitates the task of the Comptroller as appropriate. to the verification of areas and perimeters of the lots to be intervened in civil works, whether in the public or private sphere. The results of this technical report highlight the lack of accuracy of the official cartographic information of the IGAC, when using photointerpretation methods of aerial photos achieved at more than 1500 meters from manned aircraft and the effectiveness of drone technology and photogrammetry in Regarding the results obtained, it allows great accuracy, saving time and resources and improves the precision of the data obtained.
