This is my second fear mongering post seemingly focused on 10,000km-range North Korean missiles (the first can be found here). I’m really not all that concerned about North Korean missiles in my day-to-day life. The real point of this post is that the web map (here) features animated SVG symbols that are (that is, appear to be) animated along circles, not simple polylines (they actually are polylines in the shape of geodesic circles). Also, notice that the “symbols” are in fact numbers, not simple shapes, which took a while to code, so I hope you enjoy them.
A while ago I was enjoying PaperJS. It seemed like every time I searched for something to do with PaperJS, something else about RaphaelJS showed up. These two appear to be the major players in web drawing, at the moment. While PaperJS uses new technology (the HTML5 canvas element), RaphaelJS relies on SVG, making it compatible with older browsers (although apparently not with Android devices). The thing that I really like about RaphaelJS is that it’s very easy to export complex spatial shapes from ArcMap to SVG format, and use these shapes in a web drawing (I’m not sure of the easiest way to use a spatial shape in PaperJS). Here’s an example of mine, borrowed heavily from the RaphaelJS animation demos.
