Quality Model for the Evaluation of Geospatial Web Services within the Spatial Data Infrastructure of Uruguay

Abstract

Quality of Service (QoS), applied in particular to Web Services, is an area of increasing interest. One approach to deal with QoS issues is the identification of quality characteristics, usually documented in quality models. Geospatial Web Services are standardized service interfaces which facilitate the processing and exchange of distributed geographic information. These services represent the technological backbone of Spatial Data Infrastructures (SDI), which are data-exchange frameworks geared towards promoting the availability and exploitation of geographic information. This paper proposes a quality model for the evaluation of Geospatial Web Services within IDEuy: the SDI of Uruguay. The development of this model was based on requirements pertaining to the Uruguayan context, leading international SDI initiatives and related work. The application of the model to evaluate services within IDEuy is also presented.
