Does anyone know how to use the Google API or other to find the closest underground/airport to a postcode? I have succesfully done this using 2 postcodes and insert as URL to capture the XML. The distance is then parsed out using a custome function. Using this technique I have looped through the postcodes of around 300 underground stations to find the closest. It works, but Google does not allow more than 2,500 hits on its API before charging large licence fees. Is there a way to do this in one hit or a cheap plug in?
