  • 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.

So Victor checked to make sure the reviewers had written about other doctors or topics and weren't just online to rave about Reese. Victor ended up giving Dr. Reese a try and writing a favorable review himself.

The other solution was to chop off the book's binding, but that method destroyed the book.

Google isn't the only company that uses cars to photograph neighborhoods for its mapping service, but it acknowledged its vehicles also contain receivers that pick up Wi-Fi signals. The receivers were supposedly just collecting the names and addresses of Wi-Fi networks to use in mapping programs for smart phones.
