Abstract
This paper analyzes the politics of mapping along the US–Mexico border to explore how humanitarian activists wield geospatial technologies in challenging border securitization. In addition to ‘bounding’ societies within delimited territorial zones, mapping technologies have recently been elevated to encompass observing, locating, and tracking mobile bodies—outcomes that, in the context of immigration control, have heightened the risk of clandestine border crossings and produced a sharp rise in migrant fatalities. As geospatial tools have been integrated into official gatekeeping strategies, activists have deployed them to protect migrants, promote mobility rights, and disrupt borders and the spatial, legal, and technical orders underpinning their materialization and enforcement. This case study considers the political implications of these interventions, and highlights how technologies traditionally aligned with state security and surveillance have been reappropriated in the service of transnational solidarity, recognition, and hospitality.
