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.

Happy Earth Observation Day, everyone! Our guests for this special Earth Science Week episode are Rebecca Dodge of Midwestern State University and Tom Mueller from the Massachusetts Bureau of Geographic Information (MassGIS), the founding parents of Earth Observation Day which is celebrated this week. We delve into how Earth Observation Day came about, how it's grown, materials that have been developed over the years, and what’s happening around the country with it. We also touch on current EOD activities such as the NASA Aerokats, Mapathons, Landsat imagery, data collection with your phone, and much more.
