THERES A GIS IN YOUR FUTURE

Over two-thirds of governmental information is inherently spatial, yet only recently have Geographic Information Systems (GIS) emerged as the primary means to enable the spatial visualization and modelling of this immense data source. GIS is following a common evolutionary path. Transactional functions were automated by means of Computer Assisted Drafting (CAD), and Automated Mapping (AM). The development of raster and arcnode data topologies has provided the foundation for the tactical application of spatial modelling. The imminent emergence of spatial data exchange standards coupled with the recent availability of low cost graphic workstations will complete the environment for widespread GIS utilization ranging from operational to policy levels. This diffusion will be accompanied by the integration of GIS with database and communications systems and a broad set of Information Resource Management issues. © 1990.
