In a recent paper, Kaplan et al. (2018) illustrated the importance of taking pantry open hours into consideration when examining the emergency food system in rural South Central Indiana. Their approach, however, is cumbersome in that it involves the creation and animation of 62 layers within GIS. In this paper we propose and test a spatial-temporal summary measure that captures the same information as the Kaplan et al. (2018) technique. Results indicate that the measure accurately summarizes spatial-temporal data and that it facilitates both rapid visual display and inclusion in more comprehensive studies.
