2. www.1spatial.com Adjacent roads do not have parallel geometries Automatic Generalisation The first road is snapped parallel Second road snapped parallel and displaced Point symbols are in conflict with each other Points show location of the objects Point symbols buffered to identify conflicts Location for the typified symbol identified 3 symbols typified to 1 for representing at 1:50,000

3. www.1spatial.com Important Tools & Techniques  Object orientation  Adaptive/optimisation approaches  Topology  Prospective data quality audit

4. www.1spatial.com Research Questions  How do we collaborate on, share and reuse the generalisation technology we build?  Web Registry – models, constraints, goals, algorithms  Generalisation Web Service  How do we “mass produce” automatic generalisation?  SOA  GRID
