On Thursday 23 and Friday 24 of October, was developed in the auditorium of the Faculty of Engineering at Universidad Católica de la Santísima Concepción (UCSC) the “XIII Conference on Hydraulics: The use of remote sensing in Hydraulic Engineering”, an activity coordinated by the Chilean Society of Hydraulic Engineering (SOCHID) and organized by the Department of Civil Engineering of that college.
The objective of the meeting was to bring together the public, private and academia worlds, around the use of sensors that provide remotely information to use in different fields.
On the occasion, Director of Technological Development of the Center for Optics and Photonics, CEFOP, Dr. Rolando Hernández Mellado, spoke about the many practical applications, which allow obtained data and information through satellite technologies.
To do this, Dr. Hernández showed the work done by these tools, in acts of national importance. The first example cited by him was the done work in CEFOP in the volcano eruption, that occurred in 2008 in Chaiten, the Palena Province, Los Lagos Region. In that case, thanks to the collection and analysis of satellite data, could be calculated height and temperature of the ash cloud resulting from the eruption, making it possible to rule out that the material ejected by the massive, would fall in national territory. This information enabled authorities to take political and administrative decisions in a timely manner.
Another practical case cited by our Director of Technology Development, was the simulation of plane crash in the Juan Fernández Archipelago in September 2011. At the time two satellites equipped with high definition radar, which were sent, synchronized, in order to obtain accurate stereoscopic images. After that, the images were applied in aerophotogrammetric simulations of the landscape, allowing an accurate simulation of the trajectory of the aircraft and thus determining the exact place where the aircraft was precipitated at sea. “In this case, what was done was given an intensive use of satellite technology, a thorough analysis of the data obtained, which made possible the creation of simulation models”, he said.
In the presentation, researcher valued multi areas where Earth observation technology can be used for as land use planning, risk management, mapping, Environmental Science, disaster prevention, Hydrology and Atmospheric Sciences.
In this regard, he stressed the importance of human resources in this area of scientific research and technological development. “It is essential to have a preparation and training of people working in the interpretation of the data, especially in image processing”, concluded Dr. Hernandez.
