Overall, PCB congener biodegradation was observed in all treatments in the ranges of 0–99%, 2–97% and 40–94% under anoxic, oxic, or anoxic/oxic treatments, respectively. The highest ...

However, as European urbanization continues to encroach on natural areas and the climate changes it is likely that the frequency of wildfires will increase likewise the number of areas prone to wildfires. It is therefore paramount not only to increase public awareness of this natural hazard but also to be prepared by improving wildfire hazard forecasting, monitoring, and mapping.

Earth observation of the urban environment is therefore essential to keep a watchful eye on their condition. In-situ measurements are also needed to provide details that cannot be easily derived from remotely sensed imagery. Green infrastructure and the ecosystem services they provide play an important role for the wellbeing of city populations and provide resilience against the effects of climate change. EO is essential for mapping the relevant details to produce information on which to base healthy city evolution.

Each product consists of a range of information layers grouped into three categories: base layers, mosaic layers, and quality layers. A mosaic product is available for each coverage and data/country region of interest combination.

We showcase the functionalities of the system in real-world use cases which require data integration of different geospatial sources.

The increased frequency of wildfires is not only a result of a changing climate, but wildfires themselves also produce a significant amount of greenhouse gases that, in-turn, further contribute to global warming. I-REACT (Improving Resilience to Emergencies through Advanced Cyber Technologies) is an innovation project funded by the European Commission , which aims to use social media, smartphones and wearables to improve natural disaster management by integrating existing services, both local and European, into a platform that supports the entire emergency management cycle. In order to assess the impact of climate change on wildfire hazards, METEOSIM designed two different System Processes (SP) that will be integrated into the I-REACT service that can provide information on a variety of time scales.

However, hyperspectral classification and identification procedures are generally based solely on the spectral data. The S-space concept treats the spectrum as a ’spatial ’ dimension thereby facilitating the exploration of a relationship between the spectral and spatial image domains. This paper presents the ideas that will be researched as well as some preliminary results. 1.
