Find nearest latitude and longitude points

Question

Hi Folks,

An question on latitude and longitude...Probably a silly one.

I have a set of latitude and longitudes for various locations.And, I have the latitude and longitude of the location in which I am in.

Now,I have to find the nearest places from my locations from the set of latitudes and longitudes I have. Is thee any special way of calculating it or it is just mere subtraction and checking the difference?

Could you please throw some light on this?

Thanks, J

Hi

It depends on how the points are placed.

For example - if most of the points are in a parking lot, then Euclidean Distance should work well.

In other cases - Geodesic Distance needs to be computed. This link should help you with more information.

Here is the conversion from Decimal format to Degree-Minute-Second format and vice versa.
