Evaluating Performance in Spatial Data Infrastructures for Geoprocessing

Effective and efficient Web services infrastructures for geoprocessing are essential for fields such as e-government and e-tourism. However, few model-based approaches exist that let researchers analyze and measure system implementation performance. The authors present a performance evaluation of a spatial data infrastructure (SDI) implementation based on common standards. The SDI´s purpose is to compute groundwater vulnerability function. The authors study four influential performance issues: caching, network adaptation, data granularity, and communication mode
