Geotagging with SailBlogs
SailBlogs geotags information in the system in various ways that allow visitors and outside systems to search and locate information based on geographical data (i.e. latitude & longitude). This mostly applies to XJSail members that have tracking enabled.
If a latitude/longitude pair is loaded with a blog entry, that blog entry becomes geotagged.

Meta Tags
When a blog post has an associated lat/long pair, the system will automatically tag the web page with that info as a meta tag. Viewing the source of of the page will show two standard meta tags for communicating this info to other systems, mainly search engines:
<meta name="geo.position" content="-35.7233;174.3256"> <meta name="ICBM" content="-35.7233,174.3256">
RSS Feeds
The RSS Feed of a member blog will also be tagged with geo information about a post, if the coordinates were loaded along with the post. Some mapping systems, like Google Maps, can read the geo location from an RSS feed an plot it on a map. Search engines and other system also use RSS feeds extensively to find geographic-based content on the web. These tags are added to RSS items that have corresponding location data:
<geo:lat>-35.7233</geo:lat> <geo:long>174.3256</geo:long>
Images
Geotagging images is becomming increasingly popular, especially as cameras and cell/mobile phones become equipped with GPS chips as standard options. Geotagging an image involves writing the lat/long/altitude information to the image itself. At present, SailBlogs does not support geotagged images in any special way, and because of the way SailBlogs handles uploaded images, generally the original information is removed.
