15:15 – A group of researchers at the University of Technology in Vienna has developed software “guardian” of the protected areas and nature reserves of ‘ ue. The system is able to create a 3D map using the laser pulses sent from aircraft flying over the affected area, providing important information on the health of the ecosystem. The monitoring will be possible from an altitude of 500 to 2 thousand meters.

Eyes of laser – The protected areas make up almost one-fifth of the total area of ​​’ European Union. It is easy to understand, therefore, as it is impossible to control a wide area in a traditional way, ie walking. The only way to control and protect the natural reserves is the European remote sensing. “Our team – said Norbert Pfeifer, professor at the UT – has developed software that can use” light signals sent from airplanes and then reflected from the ground “to distinguish different types of vegetation.”

Nature under control – The map obtained by laser pulses contain much more information than a simple aerial photography. Thanks to special algorithms, the data collected allow to calculate not only the layers of trees and shrubs, but also those of grass and herbaceous plants, whose presence is important to check if the wood is environmentally sound. The researchers point out that the calculated parameters are the same that are collected by scientists during the inspections, but with the advantage of being able to analyze much larger areas: airplanes can indeed scan strips of land up to 800 meters wide.

Reliable results – The new algorithmic method was tested in a wild and marshy Hungary, characterized by lakes, meadows and pastures. “We have reached an agreement between the 80 and 90% between our data and those of the surveys on the spot,” said Pfeifer, explaining that it is the “same level of consistency that you expect if the same region is evaluated by two different people. “
