Many different open information sources currently exist for protecting the environment in Europe, mainly focused on Natura 2000 network, and areas where environmental protection and activities like tourism need to be balanced. Managing these data and integrating them for supporting decision makers and for novel uses is a challenging task. The SmartOpenData project (2013-1015) aims to define mechanisms for acquiring, adapting and using Open Data provided by existing sources for environment protection in European protected areas. Through target pilots in these areas, the project will harmonise metadata, improve spatial data fusion and visualisation and publish the resulting information according to user requirements and Linked Open Data principles to provide new opportunities for use. SmartOpenData will be based on previous experiences of Habitats project, which defined models and tools for managing spatial data in environmental protection areas. This paper provides an introduction to the SmartOpenData with a specific focus on the motivation, goals, and technical focus of the project, and outlines the architecture of the approach taken by SmartOpenData.

This Small Business Technology Transfer (STTR) Phase I research project objectives include the development of the Optical Parametric Amplification of Cross Correlation of Frequency- Resolved Optical Gating (OPA XFROG) for LIDAR detection that entails the assessment of the minimum measurable signal and the application to known incoherent signals. The technique has shown compelling results, however the parameters of amplification, such as pump pulse energy and crystal thickness, need to be optimized before this optical technique can be integrated into commercial instrumentation. A second objective is the design of the LIDAR instrument equipped with the optical amplification apparatus (transmitter, receiver, and optimization of the backscattered light collection). The ability to detect weak fluorescence and Raman signals using a LIDAR system has considerable impact on future remote sensing applications. Not only will remote sensing distances be significantly extended (a minimum gain of two orders of magnitude is expected) but species with spectral signatures that are too weak to be recognized against the background noise will be within the signal-to-noise ratio required for positive identification. Remote sensing of chemical and biological materials can substantially reduce the threat level to military personnel and civilians.

This Small Business Innovation Research (SBIR) Phase I project seeks to develop a low-cost, easily-deployable sensor suite capable of providing the entire flow velocity field of wake vortices produced by airplanes near airports. Large aircraft produce strong air vortices at their wingtips, a significant hazard for smaller following aircraft. Without observing the vortices, aircraft must be widely-spaced on takeoff and landing. Current systems for airport wake-vortex measurement, such as wind anemometers, Radar Acoustic Sounding Sensors (RASS) and pulsed Light Detection and Ranging (LIDAR), do not capture the detailed flow-field of the vortex, so hazardous situations like counter-rotating vortices may not be detected. The new technique is based on the use of a sensor suite located at specific points near the runway to map the vortical flow. This Phase I effort includes a demonstration of the concept using existing laboratory data (consisting of 2-D mappings of vortical wall flows), and trade studies and design of the sensor suite. The sensor concept will be prototyped and tested in Phase II in an airport setting. The broader impact/commercial potential of this project will be increased safety during take-off and landing, especially for small aircraft. Present practice is to allow a fixed amount of spacing after a particular aircraft type to allow the vortices it produces to dissipate, plus an added safety margin. The ability to directly observe the vortices will allow following distances to be based on actual conditions, allowing adaptive spacing, thus enhancing safety. In comparison with competing, more complex and more delicate LIDAR and radar-based systems, the low cost of this instrumentation will allow smaller airports, not just the largest ones, to be equipped with this technology. Such smaller airports using this capability can increase their flight capacity, thus potentially relieving larger hubs, especially if an emergency evacuation were to be declared. Larger airports can use the technology to increase overall safety, especially for smaller aircraft, allowing them to land and take off with confidence amongst the larger airliners. This effort will also increase our understanding of vortical wall flows, ubiquitous in windy conditions combined with rugged terrain. Derivative versions of this equipment will be useful for other applications, such as for emergency teams required to operate in hazardous-access, windy conditions.
