Item Inventario de elementos en zona afectada por movimientos en masa en el sector hoyo frío, corregimiento de Golondrinas, Santiago de Cali(Universidad Santiago de Cali, 2023) Taba Morales, Gebel Edilberto; Cabezas Alzate, Diego Fernando (Director)In the rural area of the Cali District, specifically in the municipality of Golondrinas, Hoyo Frío sector, situations arise that directly affect the community, one of these is mass movements. The existing information about the area, recorded in the Territorial Planning Plan, corresponds to the year 2014 in a generalized manner without considering the elements existing to the current date. Therefore, this study aims to carry out an inventory of elements that are likely to be affected by mass movements in the sector in question, taking advantage of the technological resource of remotely piloted unmanned aircraft or drones that allow autonomous flights to obtain corrected images, with which it is possible to identify and quantify elements of the territory that serve as input to carry out management in the territory. To achieve the above, an autonomous drone overflight mission was carried out in the previously identified area, establishing security measures for the operation. Subsequently, the images obtained were processed in software that allowed us to obtain products for analysis, such as digital models, both of terrain and elevation and the corrected or orthomosaic image. To analyze the information, the mentioned products were entered into geographic information systems software in which Gebel Edilberto Taba Morales. (2023) approximate measurements of areas susceptible to affectation were made using the photointerpretation technique and to facilitate the inventory, a supervised classification was carried out to estimate the number of constructions identified in the image. It was possible to obtain the number of buildings present in the area close to mass movement phenomena and a comparison was made with data from existing properties in which the changes currently identified were identified. In accordance with the above, it was possible to verify the advantages that come with the use of images obtained from drones, reducing the work time in the direct identification and on the ground of the probable areas in which constructions or infrastructure would be affected, providing supplies. that allows initiatives in order to reduce disasters or effects in a certain community.
