Location-based publishing and services
The web has been used to record many pieces of data - not only documents, and information on people and event details, but the time things occured, names and addresses, reviews of those things, what relationship people have to each other, and more. More recently, one attribute has really come to the forefront - the location of things, or geocoded data as it is called. In this article, Premasagar takes you through the world of geo data, showing what options we have for recording geo data, what tools are at our disposal, what people are doing with it already, and what the future holds.

Nice article.
What's missing along with the location/time of photos is the orientation of the camera. Recording that will save a lot of
post-processing.

I'd love to have a location aware task/reminder function on my (smart)phone.
Ideally, when I walk up to my local department store, my phone would alert me with a "grocery list" of items I need to get.

These are great suggestions.
@Dantesoft - Yes, a photo of a landmark may be taken from any number of locations, directions, altitudes and zoom levels. A simple latitude + longitude coordinate is not enough.
@Eddie - Something like Remember The Milk + Fire Eagle + Google Alerts:
"You are now 50 metres away from the fruit shop. You are running out of apples at home, why not pick up some more?"
@FataL - Thanks...

Before thinking of the usage of Geocoding, the best way to retrieve the geo data would be direct getting from browser's header, which is device dependent. This is better to be done at the browser level because mobile browsers are already device dependent. Once this can be achieved, geo data would become easily readable by any server-side platform without installing additional software or plugin. I'm loving to see this happens one day, and at the same time working on some conceptual mobile geo applications.
