Each chapter presents a general real-time tracking system example that can be easily adapted to target any application domain and that can incorporate other sensor data to make the system "participatory sensing" or "human-centric sensing." The book covers all of the components needed to develop an LBIS. It discusses cellular phone programming using the Java ME platform, positioning technologies, databases and spatial databases, communications, client- and server-side data processing, and real-time data visualization via Google Maps and Google Earth. Using freely available software, the authors include many code examples and detailed instructions for building your own system and setting up your entire development environment. Web Resource: A companion website at www.csee.usf.edu/~labrador/LBIS provides additional information and supporting material. It contains all of the software packages and applications used in the text as well as PowerPoint slides and laboratory examples.

With the presence of cheaper, miniature, faster, and smart in situ sensors, and the increasing availability of abundant ubiquitous computing devices, wireless and mobile network access, and autonomous and intelligent geospatial software agents, distributed networked in situ sensing becomes clearly a technological trend. Sensor webs can perform as an extensive monitoring and sensing system that provides timely, comprehensive, continuous and multimode observations. This new earth observation system opens up a new avenue to fast assimilation of data from various sensors (both in situ and remote) and to accurate analysis and informed decision makings. One of the critical components in developing a sensor web is to build a geospatial information infrastructure, a backbone that connects the heterogeneous in-situ sensors and remote sensors over the wired or wireless networks. This paper describes a distributed GIServices architecture, which serves as a gateway that integrates and fuses observations from spatially referenced sensors. A GIServices prototype -GeoServNet which is being developed in GeoICT Lab, York University is also introduced in this paper. What is smart sensor webs "A system composed of multiple science instrument/processor platforms that are interconnected by means of a communications fabric for the purpose of collecting measurements and processing data for Earth or Space Science objectives." This is the definition of Sensor Web from NASA Sensor Web Applied Research Planning Group. Sensor Web can be seen as an advanced smart sensor network. Business week provide a vivid and easy understanding description of smart sensor web : “In the next century, planet Earth will don an electronic skin. It will use the Internet as a scaffold to support and transmit sensations. This skin is already being stitched together. It consists of millions of embedded electronic measuring devices: thermostats, pressure gauges, pollution detectors, cameras, microphones, glucose sensors, EKGs, electroencephalographs. These will probe and monitor cities and endangered species, the atmosphere, our ships, highways and fleets of trucks, our conversations, our bodies - even our dreams."
