In A Noospheric Atlas of New York, Brett Ian Balogh (Chicago, IL) maps the hertzian space created by the New York's mass media broadcast stations. This space is not definable in the traditional terms of the surveyed boundaries of state territories, but rather by electrical field strengths and consumer markets. Geospatial data provided by the Federal Communications Commission is rendered as translucent shapes whose color is determined by the type of service (AM/FM/TV).
