Cooper, J. W.Arnold, D. B.Day, A. M.2015-11-112015-11-1119991017-4656https://doi.org/10.2312/egs.19991009We describe a system that allows the rapid creation of virtual urban models. We describe how this system can extract 3D model information from Ordnance Survey maps by using a rule-based modelling approach and a parameterised description for common buildings. We also give ideas about how this system could be extended to add detail to models generated from aerial photographs and to include historical events within the model. Finally we show how the models can support changes in level of detail and compression.
