Abstract	The geographic information system (GIS) is one of the fastest growing technologies in the world. Its ability to analyze spatial data and provide answers to many spatial problems is impressive. Spatial data are the backbone of GIS analysis, but only current and accurate spatial data can provide the appropriate framework for successful use of GIS technology. Out-of-date or inaccurate spatial data could contaminate GIS results in direct correlation to the obsolescence and inaccuracy of the spatial data. There is a great need for cost-efficient spatial data revision and quality control methods in order to fulfil the potential of GIS technology. The Ohio State University Center for Mapping has been conducting research into new techniques for spatial data revision. At the Center for Mapping a framework for revision is being developed, and some basic ideas are being tested. The framework will answer questions such as: Why and how does terrain change? How are these changes related to time? How do these changes affect existing topographic maps? How might modern technologies, such as a mobile mapping system (specifically, the GPSVan developed by The Ohio State University Center for Mapping) be integrated with other technologies for use in local revision of spatial data? This paper reviews the current status and latest results of this research and discusses the effect of this research in the field of GIS.
