Recent technological advances have led to an abundance of sensor, image, and streaming information. The ubiquitous availability of mobile processing devices, wireless sensor networks, and RFID tags in tandem with novel distributed computing architectures will enable a new range of applications. Most of the information generated by these distributed systems and applications is spatially referenced. Managing, processing, and using this geospatial information presents significant new research challenges in distributed information systems, including:

• efficient distributed, ad-hoc, and in-network geospatial information processing;
• algorithms and data structures that integrate a mobile user’s context, such as identity, location, activity, and intentions using sensed information;
• models of dynamic, real-time, and spatiotemporal data; and
• uncertainty and redundancy in geospatial sensor, image, and streaming data.

Further, emerging technologies have important implications across many application domains, including:

• transportation, tracking, navigation;
• active environments reacting to a mobile user’s context;
• sustainable management of natural environments; and
• emergency preparedness and response.

This workshop is concerned with new advances in both the theory and applications of distributed spatiotemporal information processing and analysis, for example using geosensor networks, active environments, or distributed image-based systems. Specifically, this workshop aims to bring together researchers with interests in spatial information theory and researchers with interests in specific spatial problem domains, such as ecology, natural resource management, and marine science; transportation and human navigation; and emergency management and logistics.

The organization of the workshop will be designed to foster interdisciplinary discussion and collaboration between researchers with diverse topic domains but a common interest in modeling, processing, use, or application of distributed geoinformation technologies, and sensor enabled, ubiquitous environments that can support mobile users.

The scope of this workshop includes, but is not limited to:

• Information management and coordination in geosensor networks and ubiquitous computing environments
• Spatiotemporal algorithms and data structures for mobile ad-hoc networks, geosensor networks and distributed geoinformation processing
• Embedding spatial intelligence in active, natural and built environments
• Efficient synchronization, localization, and tracking
• Processing image, video, and stream data for distributed geoinformatics applications
• Automated and semi-automated distributed geoinformation fusion
• Querying and data mining for distributed geoinformation systems
• Qualitative spatial reasoning in distributed geoinformatics
• Uncertainty and redundancy in ubiquitous environments and geosensor networks
• Collaborative navigation support and route finding
• Dynamic spatiotemporal models and architectures for distributed processing
• Real-time sensor web and geosensor network middleware
• Environmental, safety-critical, transportation, and innovative applications of mobile ad-hoc and geosensor networks
• Privacy-aware algorithms for active environments
• Visualization as well as simulation environments for distributed geoinformatics

All submissions must be original unpublished work written in English that is not currently under review in any other outlet. Submissions of that attempt to bridge the gap between spatial information theory and applications of theory to specific problem domains are especially encouraged.
