Dynamic Data for Geospatial Reasoning - A Local Data Stream
Management System (L-DSMS) and a Case Study with RDS-TMC.
Abstract
In this deliverable we present two developments. The first one
is a Local Data Stream Management System (L-DSMS) It is a general system
for configuring and (locally) executing networks of processing nodes for
data streams. Each such node receives data from one or several data
sources, processes them in a certain way, and delivers the processed data
to one or more data drains. A data drain can be the data source for the
next processing node in the network, or it can be the end application in
the whole processing chain. One of the components of L-DSMS is the SPEX XML
filtering system. It processes XPath queries on a stream of XML data and
can be used to extract interesting information from XML streams. The second
development is an application of L-DSMS for processing dynamic traffic
information. The traffic information comes from RDS-TMC capable FM
receivers. It is processed in several steps and then delivered to several
application systems, including databases, statistical analysis systems,
wayfinding algorithms, and in particular different graphical visualisation systems.
