Over the last fifteen years GIS has become a fully-fledged
technology, deployed across a range of application areas. However,
although computer advances in performance appear to continue
unhindered, data volumes and the growing sophistication of analysis
procedures mean that performance will increasingly become a serious
concern in GIS. Parallel computing offers a potential solution.
However, traditional algorithms may not run effectively in a
parallel environment, so utilization of parallel technology is not
entirely straightforward. This groundbreaking book examines some of
the current strategies facing scientists and engineers at this
crucial interface of parallel computing and GIS.; The book begins
with an introduction to the concepts, terminology and techniques of
parallel processing, with particular reference to GIS. High level
programming paradigms and software engineering issues underlying
parallel software developments are considered and emphasis is given
to designing modular reusable software libraries. The book
continues with problems in designing parallel software for GIS
applications, potential vector and raster data structures and
details the algorithmic design for some major GIS operations. An
implementation case study is included, based around a raster
generalization problem, which illustrates some of the principles
involved. Subsequent chapters review progress in parallel database
technology in a GIS environment and the use of parallel techniques
in various application areas, dealing with both algorithmic and
implementation issues.; "Parallel Processing Algorithms for GIS"
should be a useful text for a new generation of GIS professionals
whose principal concern is the challenge of embracing major
computer performance enhancements via parallel computing.
Similarly, it should be an important volume for parallel computing
professionals who are increasingly aware that GIS offers a major
application domain for their technology.
