Know your co-ordinates

Geolocation recently caught my attention, so thought of dabbling with it.There are numerous tools available to get the geo location but the one I tried is Google Geolocation.It is one of the AJAX APIs provided by google(reference Maps Basics, Developer's guide, Thasha's blog).

It deviates from actual longitude/latitude of the place when it depicts the place on the map.

I couldn't place it any where but at the bottom of my blog.Please scroll down to see the Google API(geolocator) in action

Co-ordinates tuned
I spend some time on Google Map API and learnt some more features about it. One can add overlays on the map based on the data(addresses) one has.Though google already provides feature of showing myriad utilities(hospitals. schools etc etc) on the map, but this will be handy when one's data is more customised and changes frequently.
As I have written earlier that the co-ordinates as calculated by the API vary a little , so I have added correction of point something to the latitude and longitude,that gives better results
