Another example is an environmental health application
that allows investigating the relationships between health and environmental
phenomena, like the incidence of respiratory diseases according to air quality measurements
(B?©dard, Gosselin, Rivest, Proulx, Nadeau, Lebel, & Gagnon, 2003).
Another example relates to the training of olympic-level speed skating athletes using
GPS measurements, they use SOLAP to analyze their performances on various
sections of a track according to various technical, mechanical, and meteorological
Figure 5. An example of the use of semiology synchronization in a SOLAP between
the map view (left), table view (centre), and chart view (right) spread over two
contiguous computer displays (using JMap spatial OLAP)

parameters (Veilleux, Lambert, Santerre, & B?©dard, 2004). In forestry, a 3D SOLAP
application has also been recently implemented (Brisebois, 2004) as well as one for
archaeology (Rageul, 2004). These applications benefit from the three-dimensional
aspect of space, that is, the volume of the phenomena being studied. For instance,
when archaeological excavation lots are represented as volumes, it is possible to
navigate in the various stratigraphic units to compare the lots according to their
color, granulometry, consistency, geographic and stratigraphic positions, and the
type of artifacts found (Fortin & B?©dard, 2004).
