Reverse Geocoding comes to Google Maps API

Google's Geo Developers Blog is reporting that Reverse Geocoding is now available in Google Maps API. What is reverse Geocoding?
It is a process of converting a latitude/longitude pair into an address.
Check out the sample posted in Geo Developers Blog as to how reverse geocoding works. Clicking anywhere on the map will display the address for that location.

Here's a modified version of the sample with satellite view. I clicked at a location where GM World Headquarters is located.

Google Maps API adds geocoding support for India

Google Maps API now adds geocoding support for India. However, it does not seem accurate. Here are couple of examples:

New Delhi, IN 110001 (At Least New Delhi shows up close by) However..scroll down for Mumbai, IN 400026


Mumbai, India 400026 (This is not correct - it finds Mumbai Road outside Hyderabad, India)

Geodesic Polylines on Google Maps

What is Geodesic? Quoting Google Maps API Blog
A geodesic line is the shortest route between two points on the surface of the earth, and often resembles the path that airplanes take to get you to your destination in the most efficient manner.
Google Maps API has been updated so you can now create Geodesic Polyline. I decided to give it a try by adding the optional parameter {geodesic:true} as follows:
new GPolyline(points,"#ff0000", 3, 1,{geodesic:true});

Example: (My aboutme page)


Example: Andrew Speaker's Risky Trip
