Greene & Greene properties: a map

So, I've created a map - using social-mapping tool Platial - of all the existing Greene & Greene properties I've been able to find record of. I'll also be adding a new layer of no-longer-standing Greene & Greene projects, but that's a few weeks off.Take a look, and let me know if you like this style of map and if the tool is easy to use; if so, I'll revive our Craftsman Home Registry (above) using this, so you can all add your own homes.
