the geoweb, interoperability, OGC, and random rants
January 27th, 2010

Who says Google doesn’t care about standards? When playing around with the RSS feed from Picasa Web Albums, I was pleasantly surprised to see full-blown GeoRSS GML for the geo-located items. In fact, they are recording both an Envelope and a Point for the photo. I don’t know where the Envelope comes from, because the UI only allows you to specify a point, but oh well.

<georss:where>
   <gml:Envelope>
      <gml:lowerCorner>42.4857087 -71.2902409</gml:lowerCorner>
      <gml:upperCorner>42.4984298 -71.265822</gml:upperCorner>
   </gml:Envelope>
   <gml:Point>
      <gml:pos>42.4920693 -71.2780315</gml:pos>
   </gml:Point>
</georss:where>

Now I’d just like to know why they are using RSS 2.0 with little bits of Atom sprinkled here and there…

    Good catch. I suspect the envelope is supposed to be the bbox for the collection. I’ll mention it to them.
