Data may have been generalised and may not exactly represent the location of the features. What appears to be a single symbol on the map may represent Multiple features at the same point.

GIS provides Users with the ability to use and manipulate data in ways not possible before; this raises issues about data that were not such a problem in the past. Demand is increased for a greater range of data at a higher level of accuracy and precision.
GIS makes data inaccuracies visible in ways not possible by other means. ArcMap and Webmaps-extra have powerful display features that allow the user to control the appearance according to any attribute data. Therefore not only is the geographical accuracy or inaccuracy clearer, but other attributes can be analysed and inaccuracies in the information itself become more obvious.
It is essential that users understand the quality and completeness of the data and that the data is used responsibly. It is important that the metadata is read before the decision as to whether to use the data or not is taken.
