Today Google updated the Geographic Web layer. In particular, the Panoramio photo placemarks sub-layer has over 4 times as many photos (from 80,000 to over 400,000). Because of the increased exposure since the Geographic Web Layer came out, thousands of people have loaded more photos for places all over the world. Check out Eduardo’s blog post with details about the update (Eduardo is one of the founders of the Panoramio service). Eduardo says they hope to update more frequently (the last update was early January), but they have been growing so fast they have been dealing with scalability issues. I just did a spot check and there are indeed a lot more photos to peruse. I haven’t yet confirmed whether the Best of GEC and Wikipedia sub-layers were also substantially updated. I’ll try to get some details next week.
