However the most exciting part of the update, is the ‘Enable Photo Display’ button. Which once clicked, enables loading a selection of thumbnails as you drag and move the map. Zoom in close enough to see many blue pins for best effect. As you move again, more images will load; the ones shown should always be within the current map view. The data to show images again comes from the Geocubes API, although we load actual thumbnails via our own API.

Geograph Google Earth Clusters

It’s the same download link, if you already have a copy, just right click and select Refresh on the “Geograph Google Earth Clusters” feature.

This has a number of advancements:

• Filterable – click the main title in the Places panel to open configuration options in the popup balloon. Includes options to filter by keyword or Geograph contributor. (Requires Google Earth version 5)
• Cubes/Cloud – Geocubes offers two clustering options, can how choose between then on the same popup as above
• Thumbnails – Now shows a image thumbnail in the placemark balloons.
• Shows a few coarse clusters when not zoomed on the British Isles
• Source code available! Download the GPL licenced PHP source code here

But its not all rosey – this version seems to suffer from an annoying bug, when first loads sometimes the layer ‘freezes’ and doesnt automatically update as you move around. If that happens right click on the ‘Clusters’ feature in ‘Places’ and select Refresh, doing that once seems to fix it!

Thanks to Geocubes to the amazing service that powers this – highly recommended if you have larger numbers of features to display!

Geograph Google Earth Clusters

This works in a similar way to the Geograph SuperLayer, by showing coverage overview, and then zooming in to reveal more detail. The Geocubes layer has the advantage that the clusters work into a closer zoom, and updates to the geograph database make it into the layer within hours. The SuperLayer is slower updating (weeks), but navigating should be much quicker being as its based on KML regions.

You can view also a Google Maps based version of the layer, using the Geocubes API directly.

This is only version 0.1 – there is more to be done – including being able to filter the results based on words and contributor, but this is exciting enough on its own. Once done a bit of work on tidying up the code plan to release it so others can use the geocubes service to create their own layer like this Watch this space!
