Accuracy or resolution in the representation of real-world features is key information for the application and use of GIS data. Positional accuracy is the measured or estimated error in the coordinate values for the spatial location or elevation of the digital feature. Associated with positional accuracy may be uncertainty in other spatial characteristics of the feature. These include real-world dimensions or boundary conditions. Spatial resolution represents the minimum dimensions of features that can be displayed or that can be identified or captured at a particular map scale. These spatial characteristics may be important in spatial analysis or display of the features. Where this information is available, it can be used in ArcInfo or ArcView GIS for analysis and display. This paper presents for discussion various strategies for identifying and associating accuracy or uncertainty to GIS themes. ArcView GIS and various Avenue scripts are used as tools for accessing this information for analysis and display. Spatial characteristics for several features represented by point, line, and polygon themes will be presented with expected accuracy, uncertainty, and source resolution. This information then is available for evaluation in spatial analysis and for symbolizing the features in views at various scales.
