TopoRadio

This article analyzes the construction of  TopoRadio (toporadio.org),  an interactive map that showcases publications and archives about Spanish-language radio in the U.S. The map aims to promote a more inclusive and comprehensive representation of U.S. radio history by improving the visibility of contributions from Latinx broadcasters. The article addresses how map-making historically suppressed Spanish-language radio programs and proposes using critical cartography as a framework for mapping back this history. The technical elements of TopoRadio, including publication selection criteria,  metadata design,  geocoding process,  and the appraisal of Geographic Information  Systems (GIS) software,  are described to provide scholars with a reproducible method for creating interactive mapping projects. The article concludes with an assessment of the map's effectiveness as a research tool and an analysis of the publications in the field of Spanish-language radio studies included on the map.
