Lesson 12, HTML5 Essentials 263The rest of the HTML5 family
There are other developing web technologies that are not part of the HTML5 specifi cation
that deals with markup. However, these technologies are often grouped with HTML5, and
they will let you perform tasks in web browsers and supported mobile devices that were not
previously possible. The following is an overview of some of these features.
Geolocation
Geolocation is a feature that allows the web browser’s geographic location to be pinpointed.
This information is then used to send you relevant data based on your position. Version 3.5
of Firefox was one of the fi rst browsers to use geolocation features. One example of how this
could be useful is to connect web searches with map data; for example, in an unfamiliar city
you might search for a restaurant within walking distance of your hotel. Rather than entering
your address manually, a geolocation-enabled browser could deliver your results immediately
based on your location.
With a browser such as Firefox 3.5, you can see can see geolocation working at http://www.fl ickr.com/map.
