In recent years, the number of commercially available LADAR (also referred to as LIDAR) systems have grown with the increased interest in ground vehicle robotics and aided navigation/collision avoidance in various industries. With this increased demand the cost of these systems has dropped and their capabilities have increased. As a result of this trend, LADAR systems are becoming a cost effective sensor to use in a number of applications of interest to the US Army. One such application is the standoff detection of road-side hazards from ground vehicles. This paper will discuss detection of road-side hazards partially concealed by light to medium vegetation. Current algorithms using commercially available LADAR systems for detecting these targets will be presented, along with results from relevant data sets. Additionally, optimization of commercial LADAR sensors and/or fusion with Radar will be discussed as ways of increasing detection ability. © 2015 SPIE.

The capability to detect partially obscured objects is of interest to many communities, including ground vehicle robotics. The ability to find partially obscured objects can aid in automated navigation and planning algorithms used by robots. Two sensors often used for this task are Lidar and Radar. Lidar and Radar systems provide complementary data about the environment. Both are active sensing modalities and provide direct range measurements. However, they operate in very different portions of the radio frequency spectrum. By exploiting properties associated with the different frequency spectra, the sensors are able to compensate for each other's shortcomings. This makes them excellent candidates for sensor processing and data fusion systems. The benefits associated with Lidar and Radar sensor fusion for a ground vehicle application, using economical variants of these sensors, are presented. Special consideration is given to detecting objects partially obscured by light to medium vegetation. © 2015 SPIE.

We conducted an analysis of the damages caused by the natural disasters which have occurred in the last 60 years in order to demonstrate that prevention costs much less than repairing the damages, without considering the loss of human lives. Between 1951 and 2009, the total cost of the damages caused by landslides and floods in Italy, revalued on the basis of ISTAT indexes 2009, amounts to more than 52 billion euros, approximately one billion euros per year. The Ministry of Environment estimated at approximately 40 billion euros the financial need to mitigate the risk of landslide and flood. The annual available funding allows the mitigation of landslide and flood risk in over 100 years. On the other hand we are forced to use Civil Protection's funds to address emergency caused by landslides or flood at least once a year in Italy: these funds, if used for prevention, would mitigate risks in wider territories and to avoid the loss of lives, optimizing the cost-benefit ratio. © Springer-Verlag Berlin Heidelberg 2013.

Since its formal institution in May 2012, the Italian Biodiversity Network is aggregating data from several research centres, for a total of ca. 1.5 million records. Botanical data made ca. 50% of the total, and range from primary biodiversity data to ecological, morpho-anatomical and taxonomical information. However, this is only a small portion of the total amount of botanical data which could be aggregated and exposed to the scientific community, professionals and citizens. In this paper we present the current status of data aggregation of the Network and its impact on digitalisation of biodiversity data, research, conservation and environmental management and education in Italy. © 2013 © 2013 Società Botanica Italiana.

LSA Autonomy purposes a ground vehicle mounted LIDAR-based methodology that employs advanced sensor processing algorithms to reliably detect partially obscured objects, such as roadside hazards, beneath light and medium vegetation. Our approach leverages both sensor domain and point cloud analysis. By employing our proven sensor domain analysis techniques, we are able to accurately pre-classify laser returns at the sensor's full data rate. Following the sensor domain analysis, a local world model is constructed from a temporal history of pre-classified LIDAR points. The local world model significantly improves the likelihood of penetrating obscuring foliage and accumulating detections from objects beneath the foliage. Objects that are partially obscured by clutter are identified as potential concealed hazards and reported to the user for further assessment. We leverage our existing LIDAR sensor processing framework to accelerate laser point classification and object recognition. The result is a robust and reliable detection algorithm for partially obscured roadside hazards.
