Geographical information
GeoRSS feed
If the Meta geo. tags didn't capture your imagination then hopefully the Geo RSS feeder file will! This is simply an
XML file which can be fed into various internet maps to give them a new dimension (formally known as a layer!). The XML file has
a standard set of XML tag names with variations being created by several companies. The main XML format is simple but is translated in
different ways by the map providers.
I have created a simple GeoRSS.xml file for the Greenwich Church
web site and called it GeoRSS.xml. You can view this file
within a browser to appreciate the structure. It is a text file so you can create your own using a simple text editor. You can then test
its validity using this FEED Validator.
You can now appreciate the alternative map services as they apply the Geo RSS feed :
You can also embed the map into a web page :
You have probably noticed that the Longitude/Latitude references are different between Google Maps and Microsoft Virtual Earth! And to
add to the confusion the Greenwich Meridian Line is no longer Longitude zero. So whatever application you use make sure there is
compensation for this anomaly.
And here are the icons I have created to alert of the Geo RSS feed :
