    Abstract
    There are many situations in GIScience where it would beuseful to be able to assign a region to characterize the space occupied bya set of points. Such a region should represent the location or configurationof the points as an aggregate, abstracting away from the individualpoints themselves. In this paper, we call such a region a ‘footprint’ forthe points. We investigate and compare a number of methods for producingsuch footprints, with respect to nine general criteria. The discussionidentifies a number of potential choices and avenues for further research.Finally, we contrast the related research already conducted in this area,highlighting differences between these existing constructs and our ‘footprints’.
