Geographic masking is the deliberate alteration of locational data to preserve the privacy or integrity of the data being displayed or analyzed. For example, the locations of the nests of endangered bird species may be publicly posted on a web site, but the availability of this data could create inappropriate visits that could disturb or endanger the birds, and so should be masked.

This GITA sponsored webinar on January 20th will discuss masking in the context of geospatial privacy, a topic of great national concern in the era of social media and Wikileaks.  Most of the methods in current use will be discussed, along with their advantages and disadvantages.  How the methods are implemented and what impact they have on geographic and spatial analysis are explored.
