Filter Results by Distance from user location

[martinbagshaw]

Though we have limited results to UK only addresses, it would be good to be able to filter / order results by distance from the user's location in the form.

When entering my postcode (CM27JP) into the form, with age of 45, I receive 31 results, postcodes for the first few are as follows:

1. CF14 2TL - Cardiff
2. CB1 8RN - Cambridge
3. CB2 0QQ - Cambridge
4. CB2 0QQ - Cambridge
5. CB2 0QQ - Cambridge
6. CB2 0QQ - Cambridge
7. CB2 0QQ - Cambridge
8. SW17 0RE - Wandsworth
9. CB2 0QQ - Cambridge
10. SM2 5PT - Sutton

Do we want to show closest results immediately after the search / as default, or provide the user a filter to organise them after the initial search?

In a branch I am working on, I am...

• Using Bing API to convert postcodes into coordinates. Using a personal API key to make this work
• Using Haversine Formula as suggested here to calculate the distance as the crow flies between two points.
• Taking the above approach, as other more accurate / useful solutions that take into account actual driving distance are paid services, for example Google Distance Matrix, and the Bing equivalent. Open to other suggestions, needless to say.
