What Are the Disadvantages of GIS?

Disadvantages of using a geographic information system, or GIS, are that its technical nature might portray results as being more reliable than they actually are, and errors and assumptions can be hidden, leading to a lack of questioning into the results. Another disadvantage of analyzing the results from a GIS is that the results will only be as accurate as the data that they come from. Because of this, the data may not be able to serve different contexts, particularly if the data is not applicable.
