The present invention is directed to utilizing monitoring devices (200) for determining the effectiveness of various locations, such as media display locations (150) for an intended purpose (media display exposure). The monitoring devices (200) are distributed to a number of study respondents. The monitoring devices (200) track the movements of the respondents. While various technologies may be used to track the movements of the respondents, at least some of the location tracking of the monitoring device (200) utilize a satellite (105) location system such as the global positioning system ("GPS"). These movements of the respondent and monitoring device (200) at some point coincide with exposure to a number of media displays (150). Geo data (movement data) collected by the monitoring devices, is downloaded to a download server (300), for determining which media displays (150) the respondent was exposed to. The exposure determinations are made by a post-processing server (400).
