At University of Technology Vienna was developed software that is able to explore and preserve protected areas of all the European Union. With this new method, you can create a three-dimensional map of the area in question by the laser pulses coming from planes transiting the area. The height from which the software acts to perform the analysis of the land below is between 500 and 2000 meters.
Europe is made up of about one-fifth of its extension from protected areas. Given the magnitude of this environmental heritage, you can easily guess how difficult to monitor and store the health status of these areas using the traditional method of to walk for every meter conduct surveys. The only way to protect our natural reserves remains, therefore, the detection air through special tools and explains how Norbert Pfeifer , a professor at the UT, is just what his team has developed “a software that takes advantage of the light signals that depart from the aircraft and are reflected on the ground. “
In this way you get a 3D map much more detailed than a simple photograph because, thanks to complex algorithms developed, the software is able to distinguish trees shrubs and is also able to detect the layers of the grass plants. These layers are essential to ensure the health of forests. The data that collects the monitoring program are in every way similar to those that are collected from employees when making site surveys. The only difference is that with this new method can be cover much larger areas in a short time, because the plane scans from a height a strip of land of the width of 800-900 meters width.
The first tests were carried out in Hungary and the data that have been collected have a at the 90% with those collected on the ground. According Pfeifer this percentage reflects the same difference detection made by two different people on the same area.
