I like using diagrams as a way of showing information flow or browser behaviour, but large diagrams can be daunting at first glance. When I gave talks about the Application Cache and rendering performance I started with a blank screen and made the diagrams appear to draw themselves bit by bit as I described the process. Here's how it's done: Specification. 1.
Introduction GeoJSON is a format for encoding a variety of geographic data structures. A GeoJSON object may represent a geometry, a feature, or a collection of features. GeoJSON supports the following geometry types: Point, LineString, Polygon, MultiPoint, MultiLineString, MultiPolygon, and GeometryCollection. Features in GeoJSON contain a geometry object and additional properties, and a feature collection represents a list of features. Specification. 1.

GitHub - hallahan/LeafletPlayback: This is a Leaflet plug-in that plays back points that have a time stamp synchronized to a clock. A Leaflet map with Node.js and MongoDB – denelius. Based on a number of comments, and the level of interest, I have updated this tutorial which I originally posted in 2014 addressing items, including, amongst other things, removing Mapbox libraries and updating the template engine from jade to pug.
Please get in touch via email or comments if you have any feedback. I wanted to explore the Node.js environment with a view to building a very simple mapping application. Initial searches didn’t reveal too much in the way of Leaflet, Node.js and MongoDB examples other than the OpenShift plug example by Steve Pousty back in 2014, which is a great start but I wanted a few more layers and an excuse to use the pug template engine (formerly jade). I attended an informative workshop by Steve Pousty at the 2014 FOSS4G event in Portland OR, same bundle, but with Flask rather than Node.js.
We have been using CartoDB for bird tracking data for a while now and are very happy to see that we have inspired others to do the same, including for other species.
To introduce even more people to this great tool for animal tracking data, I was invited to give a hands-on course at two workshops. Rather than handing the course material to the participants of these workshops only, I decided to publish it here on this blog, so anyone can use it. Introduction.
