Geographical Information Services Classification Based on FCA - A Case Study in Vector Spatial Statistic Analysis

The classification of geographical information services is very important to the effective management and sharing of geographical spatial information, especially in a web-based GIS system. However, most current classification criteria focus on an abstract level. Discussions on the detailed services classification are still insufficient. This paper proposes a new thought of constructing these diverse services using the Formal Concept Analysis (FCA). After briefly discussing the current services classification systems and basic knowledge of FCA, the paper takes vector data spatial statistic analysis as an example to perform the classification with the method of FCA. The resultant categories prove to be acceptable and practical.
