PODCAST

Spatial Signals

Spatial Signals is a podcast about remote sensing, GIS, and geospatial technologies - but more importantly it’s a podcast about the people who use and apply them. This podcast is sponsored by AmericaView, the national remote sensing network dedicated to empowering Earth Observation. Your hosts are Dr. Bradley Shellito from Youngstown State University and Mr. Chris McGinty, the Executive Director of AmericaView. New episodes every Monday morning.
