Opis

Parallel processing is a technology now coming of age in a diversity of application domains, notably GIS where large data sets are involved. This text focuses on the ways in which technology can be applied to GIS applications, emphasizing software

Spis treści

Section 1 Concepts and software infrastructure: introduction; the development of hardware for parallel processing; the software environment and standardization initiatives; the design of portable parallel utility libraries. Section 2 Modular design of parallel algorithms: design issues and requirements; a generic vector topological data model; a modular approach to parallel GIS algorithm design; parallel sort/merge techniques for processing vector data; creation of vector topological data structures; raster data management in parallel. Section 3 Design of selected GIS operations: vector-to-raster conversion; raster-to-vector conversion; vector polygon overlay; implementation case studies I - the generalization of raster data; implementation case studies II - raster- vector conversion. Section 4 Related development in parallel processing: parallel database technology - a review; algorithms for parallel terrain modelling and visualization; parallel processing for spatial statistics and spatial analysis; parallel methods for remotely-sensed image analysis.
