The rapid proliferation of applications using geographical information combined with the growing accessibility of vast quantities of data of all kinds has given rise to a number of data protection challenges. Information is placed in geographic context by governments, private sector actors, and even by individuals; compilations of data may be sole-authored or crowd-sourced, and are frequently made available over the internet. This paper explores a key question in the data protection context: when is information placed in geographical context personal information? Particular challenges in answering this question include the way in which geographical information may be a key to re-identifying de-identified data, and how it can be used to link aggregate demographic data to specific individuals.
