Aim of the workshop
-------------------
With the development of new sensor and communication technologies,
there is an ever more pressing need for reliable and properly codified
methods for deriving high-level information from masses of dynamic
spatio-temporally distributed data. Data sources of relevance here
include wireless sensor networks, CCTV, GPS, crowd-sourcing, and many
others. The data may in some cases be understood as sample points from
a continuous dynamic field, in other cases they may represent discrete
objects forming crowds, swarms, or other collective entities. The
desired high-level information can include the identification of
objects or object-like aggregations, and the processes and events that
they participate in, e.g., motion, expansion, contraction, splitting,
or merging. Although much work is now being done on investigating such
phenomena, there is still a need for a unified theoretical framework
and common vocabulary to support the development of tools and
techniques for handling them.
 
This workshop aims to bring together researchers interested in the general
area described above, and to solicit papers covering a range of
related topics, such as

* representation techniques (e.g., Voronoi diagrams; lifelines,
  histories and trajectories) 
* algorithms (e.g., spatial footprint generation and tracking,
  decentralised spatial algorithms)
* formal theories (e.g., spatio-temporal calculi, process and
  event algebras, bigraphs)
* applications (e.g., emergency management, security,
  traffic management, behaviour monitoring, environmental monitoring,
  ubiquitous computing)
* visualisation and interaction (e.g., mobile and ubiquitous
  devices, natural language interaction, volunteered / crowd-sourced
  geographic information, ambient intelligence) 

We are looking for papers handling any of these topics with reference
to the general theme of the workshop, identifying objects, processes,
and events from distributed spatio-temporal data sources. The accepted
papers will be included in the electronic COSIT conference
proceedings. 

We also aim to approach a publisher with a view to
subsequently issuing a selection of papers from the workshop
(suitably extended and polished), either as a self-standing book or a
special issue of a journal.
