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.

LeafletJS

I switched the blog over to LeafletJS maps and Open Street Map from Google Maps today. 🗺

While the Google API was convenient, I always worried about getting a flood of blog traffic at some point and having to pay for excess map requests – which is one of the reasons I’ve been doing fewer Google Maps recently.

The nice thing about LeafletJS is that it is entirely agnostic about tile provider – you can use any basemap or even locally served ones. The API is a lot more flexible, with more plugins and options – and let’s be honest, Open Street Map is nearly as good if not better than Google Maps.

I am removing the Google Maps terminology over time in favor of genericitized KML terms because Google Maps says in their license agreements that your only supposed to use their corporate name when using their mapping software, to refer to use to their service.

Structure from motion – Wikipedia

Structure from motion (SfM)[ is a photogrammetric range imaging technique for estimating three-dimensional structures from two-dimensional image sequences that may be coupled with local motion signals. It is studied in the fields of computer vision and visual perception. In biological vision, SfM refers to the phenomenon by which humans (and other living creatures) can recover 3D structure from the projected 2D (retinal) motion field of a moving object or scene.
