In order to do a successful search, you can enter your search in one of THREE ways:

• Enter the 5 digit Zip Code of the area you wish to research:
  78701
• Enter the city name and the two character state abbreviation with the appropriate comma:
  Austin, TX
• Enter the city name only:
  Austin

The way it works:

Each zip code and each city is associated with a latitude and longitude. Each course in the database is also associated with a latitude and longitude. The two sets of coordinates are used to calculate distance. Of course these are not precise distances based on miles that one would drive in a car. But they do give a good representation for planning purposes of general distance. The calculation between two coordinates is:

x = (sin(Chosen Latitude/57.2958)*sin(Golf Course Latitude/57.2958))+(cos(Chosen Latitude/57.2958)*cos(Course Latitude/57.2958)*cos(Course Longitude/57.2958 - Chosen Longitude/57.2958))
miles = 3958.75*(atn(sqr(1-(x*x)))/x)

The Chosen Latitude and Chosen Longitude are the coordinates for the destination chosen. The Golf Course Latitude and Golf Course Longitude are actually the designated coordinates for the zip code of the golf course.
