In the context of spatial planning, environmental management and monitoring a number of geospatial technologies allow operators and experts to capture, store, process and display an unprecedented amount of information about the environment and a wide variety of phenomena. However the extremely wide range of data available poses a critical challenge to operators that need to extract key pieces of knowledge from very large and heterogeneous sets of geospatial information. Within this scenario the domain of GeoVisual Analytics (GVA) can provide effective solutions to ensure better environmental control and to prevent environmental crisis. This paper presents the current challenges that GVA needs to face in the context of environmental protection, highlighting current technological, infrastructural, economical and legal implications at the international level. Finally the chapter shows how these issues have been tackled by the authors presenting the results of their current research activities.
