  • The system has several underlying database tables, including zip codes, cities and station data. The zip code and city tables, in addition to containing information about the locations, also include the latitude and longitude for the centroid each location.
  • At the core, the system works based on latitudes and longitudes.
  • Once we have the latitude and longitude, we perform a series of calculations based on the Great Circle Calcuation (GCC), which helps us to determine distances on a curved surface (ie. the Earth - and we are assuming that it is not flat). Using the GCC, we look for stations near the latitude and longitude, based on a 100 mile radius from that point. From that list of stations, which is too inclusive, we start our process of narrowing down the results to the actual stations that can be heard.
