Summary:An original integration of three concepts, namely finite elements, geoparametric transformations, and Hyper Maps and their application to the management of the water network in the region of Lausanne, Switzerland are described. The finite element method allows the simulation of network flows and 2-D or 3-D fields as well as the projection of both network and simulation data onto aerial pictures or maps. The projection method is a geoparametric transformation where the discretized fields do not represent pressure, temperature or chemical concentration anymore, but the geographical coordinates of any coordinates system. The geoparametric transformation produces a raster image where each pixel is associated with an object identifier. These pictures are called Hyper Maps. Clicking an object will display a full object description or Quick Time movie of the local pressure or chemical concentration in a network.
