Streaming GIS using PostGIS & SQLstream
Wireless sensors and internet services are generating data faster than conventional database technologies can process that data. In particular, mobile resource management requires the stream processing of high volume, location-based data. Solutions require new methods such as Streaming SQL to address these new sources of big data, in real-time.
This presentation will discuss key concepts in stream computing, data warehouse feeds and the integration of PostGIS into a high performance streaming environment. We will demonstrate the solution with examples from SQLstream's commercial traffic monitoring application, presently deployed across New South Wales, Australia.
