Decision makers in physical planning use GIS more and more. The gap between physical reality, conceptual models, and data models has been a barrier for decision makers and analysts.
Up till now the data models have been based on the primitives--points, lines, and polygons--but the decision makers will have an increased need of working objects oriented with their appropriate areas. The possibility of encapsulating data and implementing a specified behaviour in the shape of geo-objects will mirror the reality much better and thereby add intelligence into the basis of the analysis. This will be examined and argued for by case studies in physical planning, exemplified by traffic.
