Temporal & 3-D Representations

Although the vast majority of GISs currently work only in two dimensions, across the plane, certain applications require the addition of other dimensions, namely time or elevation/depth. Most geological applications require a consideration of attributes in the vertical dimension, as well as the horizontal ones. Oceanographic and meteorological models need to consider variations both in the vertical and temporal dimensions. This presentation will looks at how these additional dimensions can be incorporated into GISs
