OpenLayers has a cool example of using Flickr API to pull photos for a bounding box. When I saw this example, I right away thought about making it better by adding Panoramio photos as well with their API. This example of using Panoramio API with OpenLayers was helpful and I made a quick demo of Flickr and Panoramio Photos with OpenLayers. I have used Bing tiles and limited the zoom but than I noticed “Uncaught TypeError” errors in the console on page load. In Chrome it was Uncaught TypeError: Object #Object has no method ‘c1′ and FireFox gave me TypeError: OpenLayers.Protocol.Script.registry.c1 is not a function.
In my last post, I dived into OpenLayers and created a demo that uses different data sets, layers, and tooltips. Today, I am creating something very similar but serving a different purpose: visually comparing something with different data sets of geographical points. That sounds confusing, but I am referring to a concept like airports and grabbing data about airport locations from various sources and visualizing the differences between the sources. You can just look at the size of the data source and determine that it is larger and has more airports but plotting geo locations on a map and seeing it with your eyes can bring more insight.
