I’m trying to enter some zip codes (done!) and then create a radius (in km or miles) to then get back the zip codes inside the circle
Can anyone help?
I did something similar in Xojo here: http://www.etskillsacademy.org.uk/cgi-bin/NSAetPublicRegister/nsaetpublicregister.cgi
I have a database of Trained employers with postcodes. On launch of the Xojo app it looks to see if any have a postcode but no latitude/longitude, and if so, looks up these details via Google.
The web user puts in their postcode (or any address details) and it then uses a method to calculate the distance of every employer from the user’s postcode. It then shows the closest 10/20/50, etc both in list and map format.
Is there a part of these steps that you need?
