Temporal operations allow the manipulation of temporal dimensions,
while keeping the same level of thematic and spatial granularities. Spatial operations
allow the manipulation of the spatial dimensions while keeping the same level of
thematic and temporal granularities. Spatial operations can be executed directly by
clicking on the elements (dimension members) shown on the maps.
SOLAP tools can support different types of views: tables, various types of diagrams
and charts, and various types of maps. These include simple maps (i.e., single maps
showing many geometric elements), multimaps (i.e., many maps, each related to a
particular parameter, for example, one map per year), complex thematic maps (i.e.,
thematic maps composed of superimposed visual variables, e.g., color, pattern,
shape of symbols, one per selected measure), and maps with superimposed diagrams
(i.e., maps with little charts superimposed on the geometric elements of the map).
The SOLAP views can support operator synchronization and graphical semiology
synchronization. Figure 5 presents an example of a SOLAP display comprised of
