[georss] GeoRSS Feeds with multiple geometry types

[Steve Lombardi]

For item 1, you can create a Live Search Maps Collection and subscribe to its feed. You can put a mix of geometry types in it. The feed is updated in realtime as you edit the collection - this may help you in your testing related to item 2, but probably isn't exactly what you are looking for.

For example, here is a Collection in Washington DC - it has Zip boundaries shaded by area and some random Points of Interest:

http://maps.live.com/?v=2&cid=2BBC66E99FDCDB98!9414&encType=1
if you hit the subscribe link, you get:

http://maps.live.com/GeoCommunity.asjx?action=retrieverss&mkt=en-us&cid=2BBC66E99FDCDB98!9414

which is the GeoRSS feed for the Collection containing full geometry.

You can fetch GeoRSS feeds for KML files in the same manner:

Here is a snippet from a blog post I'm writing that talks more about this:

Subscribe to changes in a KML file via RSS. Earlier this year we introduced a feature to enable <file:///C:\Users\stevelom\AppData\Roaming\Windows%20Live%20Writer\PostSupportingFiles\ce504787-1d70-407c-8838-95d279c46bfe\image%5b37%5d.png> [cid:image001.png at 01C8155F.FDD41430] <file:///C:\Users\stevelom\AppData\Roaming\Windows%20Live%20Writer\PostSupportingFiles\ce504787-1d70-407c-8838-95d279c46bfe\image%5b37%5d.png> <file:///C:\Users\stevelom\AppData\Roaming\Windows%20Live%20Writer\PostSupportingFiles\ce504787-1d70-407c-8838-95d279c46bfe\image%5b37%5d.png> you to pluck an RSS feed for a Collection for use in your news reader of choice. All of the convenience of staying up to date on your favorite blogs brought to spatial data! With this release we've extended this support to KML files hosted on the web. Best of all, using it is identical to plucking a feed for a Collection. Once added to your news reader, you'll be alerted whenever the author of the original KML makes edits or additions to their  file. Best illustrated with an example. Here is a KML file<http://maps.live.com/?mapurl=http://www.gearthblog.com/kmfiles/moontrees.kmz> showing the location of moon trees<http://nssdc.gsfc.nasa.gov/planetary/lunar/moon_tree.html> planted in the US. When the KML viewer opens you can click the subscribe button to grab its RSS feed and add it to your newsreader. [like this<http://maps.live.com/GeoCommunity.asjx?action=retrieverss&mkt=en-us&cid=&mapurl=http://www.gearthblog.com/kmfiles/moontrees.kmz>] behind the scenes, what is served out is the GeoRSS flavor of RSS so your KML subscription is viewable in traditional readers as well as those with explicit support for Geography! When the author adds or edits the original file, changes will show up at the top of the news feed.


Hope this helps!

Subject: [georss] GeoRSS Feeds with multiple geometry types

Hi,

I looking into building a GeoRSS aggregator, but I'm struggling to find the following types of GeoRSS feed:

1) Feeds that contain multiple types of geomtery, I'm guessing it's not very common for people to publish a GeoRSS feed that contains both points and polygons?
2) Feeds that update frequently, for example, every 15 minutes - 1hr?

If anyone could point me in the direction of public feeds that demonstrate the above, I'd really appreciate it.

Kind Regards,

Rob
