Environmental Big Data: a systematic mapping study.

Big data sets and analytics are increasingly being used by government agencies, non-governmental organizations, and privatecompanies to forward environmental protection. Improving energy efficiency, promoting environmental justice, tracking climate change, and monitoring water quality are just a few of the objectives being furthered by the use of Big Data. The authors provide a more detailed analysis of the emerging evidence-based insights on Environmental Big Data (EBD), by applying the well-defined method of systematic mapping. The analysis of results throws light on the current open issues of Environmental Big Data. Moreover, different facets of the study can be combined nto answer more specific research questions. The report reveals the need for more empirical research able to provide new metrics measuring efficiency and effectiveness of the proposed analytics and new methods and tools supporting data processing workflow in EBD
