摘要：
In this paper several new aspects of spatial data warehouse modeling are presented. The extended cascaded star schema in spatial distributed data warehouse DSDW was defined. Research proven that there is a strong need for building many SDW's extended cascaded star schemas as an outcome of separate spatio-temporal telemetric conceptual models. For one of these new data schemas, the definitions of cascaded ECOLAP operations were presented. These operations base on a relation algebra, and make possible ad-hoc queries executing.
