An Implementation of High Performance Web-Based GIS on Parallel Cluster using MPI

摘要

The use of Web-Based Geographic Information System (Web-Based GIS) with spatial data has become popular and has played an important role in managing resources of humans. However, there are limitations on using this system with a typical large size of GIS datasets and complex calculation of GIS Junctions. In this paper, we propose a new version of Web-Based GIS by applying the parallel processing technique to improve the efficiency of data processing. MapServer, which is an open source Web-Based GIS, is used as an original program. Moreover, to develop the parallel processing technique, MPI is applied as a standard library. By combining the parallel processing technique and MapServer, the new system called Parallel MapServer has increasing efficiency of data processing with less than or equal to 12 processors.
