Hi,
For a search for pictures taken within a certain distance from a location, what is the required format for latitude and longitude?

Decimal degrees.  The same format that Google Maps uses by default.

Thank you. Any restrictions regarding the number of decimals?

I don't think so, but don't expect more decimal places than 10-12 to make much difference.

1 degree of arc is 60 nautical miles on the Earths surface. 60 x 1852m = 111120m = 111120000mm or 1.1112E8mm. If I got this right, one degree of arc stated in 8 decimals means roughly 1mm accuracy. 12 decimals means 1/10000mm, 14 decimals means 1/1000000mm. None of my GPS receivers can match that!
