Urban environmental management: monitoring, GIS, and modeling

K Fedra
1999 Computers, Environment and Urban Systems  
To provide decision-relevant information supporting planning and management, these components are integrated in models for scenario analysis and optimisation tasks.  ...  Urban environmental management must integrate the spatial, structural features of a city, typically captured in geographical information systems (GIS), and the dynamics of environmental quality indicators  ...  This can be derived from monitoring data directly, i.e. by time-series analysis methods. It can, however, also be based on simulation modeling.  ...
