A generic geovisualization model for spatial OLAP and its implementation in a standards-based architecture

Abstract : Spatial Data Warehouse (SDW) and Spatial On-Line Analytical Processing (SOLAP) systems are technologies intended to support geographic business intelligence. SOLAP clients provide a cartographic representation of facts on maps, and perform SOLAP operations through simple user interactions with the maps. Services are unassociated, loosely coupled units of functionality that are self-contained. A Service Oriented Architecture (SOA) is an architectural design pattern where each tier is defined by means of a set of web services. (Un)luckly, there is currently no standard approach to implement SOA solution for visualizing the results of SOLAP queries. Existing SOLAP clients are not flexible and provide closed ad-hoc implementation policies for the visualization of SOLAP queries, which is an important obstacle to interoperability. In this paper we propose a data model for the cartographic visualization of SOLAP queries. Based on this model, we present a new SOA architecture for SOLAP systems where the SOLAP client is totally based on standard data representations (e.g. XMLA, SLD, etc.), and cartographic visualization web services (XMLA, WMS, etc.).
