Abstract

Effective and efficient Web services infrastructures for geoprocessing are essential for fieldssuch as e-government and e-tourism. However, few model-based approaches exist that let researchersanalyze and measure system implementation performance. Here, the authors present a performanceevaluation of a spatial data infrastructure (SDI) implementation based on common standards. The SDI'spurpose is to compute groundwater vulnerability function. The authors study four influentialperformance issues: caching, network adaptation, data granularity, and communication mode.
