I added additional layers to the KMZ/LeafletJS maps on the blog … 🗺

On the whole, LeafletJS’s API is similar if not in some cases simpler and more straightforward then Google Map.

I have to admit that the feature that allows you to use any WMS map in the background in QGIS is a really neat feature. You can load Forest Service Topos, or any layer from the National Map or state WMS services, automatically onto a map, and easily switch between them. Definitely some neat technology — and it’s free of Google, so you never have to worry about either their servers going down or being charged for overage use.

The only downside I have found so far is that KMZ files tend to render more slowly compared to Google Maps, as Google often does a lot of processing on their servers, compared to LeafletJS which is entirely done on the browser side.
